TAKE A MOMENT - Since tomorrow is Veteran's Day,
formerly called Armistice Day, take a moment to remember
this country's veterans, especially those who never made it home.
SEVERE WEATHER PUMMELS THE OHIO VALLEY -- Severe thunderstorms
accompanied by high winds moved through the Ohio Valley and across
the Appalachians during Thursday afternoon and evening. These
thunderstorms were in association with a storm system that had
moved from the lower Mississippi Valley to the Great Lakes on
Thursday. As of late evening, 78 reports of high winds were made
from Kentucky, southern Indiana, southern Ohio, Tennessee, Virginia
and the western Carolinas. In Knoxville, TN the high winds caused
a large tree to fall on a pickup truck, killing two children and
injuring their father. These winds also felled numerous trees
and power lines. A 92 mph wind gust was reported at Bowling Green,
KY . Large hail was also reported in suburban Louisville, KY.
Earlier in the day, severe thunderstorms produced wind damage
in Alabama and northern Georgia, where large hail also fell.
The occluding low pressure center as of late Thursday night was
located over western Lake Erie with an occluded front that extended
southeastward over Ohio, where a warm front extended eastward
across the Appalachians to the Del-Mar-Va Peninsula, while a cold
front continued southward along the Appalachians to the Florida
Panhandle and out across the Gulf of Mexico. Thunderstorms continued
along the cold front, especially across southeastern Ohio, western
Pennsylvania and West Virginia. This area was under severe weather
watches. Additional thunderstorms were also detected farther south
along the cold front, across the Piedmont of the Carolinas. A large
precipitation shield also extended around the northern and western
sides of the system, from the Middle Atlantic and southern New
England westward to the central Great Lakes.
The storm system is expected to continue its occlusion process
as the primary low pressure center moves northward into Ontario.
A secondary low is forecast to develop near the point of occlusion
and move to the lower Delaware Valley Friday morning. By evening,
the secondary low is expected to move northeastward offshore of
the Middle Atlantic coast, while the primary low dissipates over
Ontario. A slight risk of severe thunderstorms continues through
Friday morning for a region to the east of the advancing cold
front, extending from the eastern lakes southward to the Carolinas.
As much as 1.5 inches of rain could fall across New England between
Friday and Saturday mornings.
WINTRY WEATHER ACROSS THE WEST -- Essentially all of the
nation west of the Mississippi experienced unseasonably cool weather
on Thursday as afternoon high temperatures were below the long-term
average highs for the date. The largest departures where across
Montana, where high temperatures ranged between 25 and 35 degrees
below the average. Several locations set daily low maximum temperature
records, to include Sioux City, IA (23 degrees), Sioux Falls,
SD (23 degrees), Amarillo, TX (34 degrees), Texarkana, AR (45
degrees). Record low temperatures were also set at Sioux City,
IA (13 degrees), Amarillo (16 degrees), Liberal, KS (16 degrees),
Goodland, KS (16 degrees) and Del Rio, TX (33 degrees).
A large and diffuse region of low pressure situated over the Great
Basin on Thursday night was expected to produce heavy snows across
much of the Rockies through Saturday morning. One low pressure
center located over northwestern Arizona had an accompanying cold
front that stretched southwestward into southern California. Another
low center was located over the central Sierras. Widely scattered
light precipitation was detected across the West.
The low pressure area over northern Arizona is expected to drift
eastward on Friday. Precipitation in the form of mountain snow
is expected to continue with some significant accumulations. A
winter storm warning was in effect through Friday for much of
Utah, as 1-2 feet of new snow are expected in the northern Wasatch
and the Uinta Mountains, while in the southern mountains, 3 to
6 inches could fall. Snow advisories were posted for portions of northern
Arizona, Nevada and Wyoming, where as much as 6 inches are likely
by late Friday. A winter storm watch was posted effective Friday
and Friday night for Colorado west of the Continental Divide,
along with adjacent counties in Utah. As much as a foot of snow
was expected, along with southwest winds to as high as 35 mph.
With relatively clear skies across the lower Mississippi Valley
and southern Plains associated with cold high pressure, vigorous
nighttime cooling should result. Freeze warnings were issued for
portions of west Tennessee and northeast Arkansas in the vicinity
of Memphis, TN, and the Hill Country of central Texas. Cold air
spilling into northern California necessitated frost advisories
for the central valleys of that state.
UPPER AIR -- The upper air charts for 00Z on Friday revealed
a large height trough over the West Coast. This trough reflects
the cold air that continues over the region. A height ridge is
found across the East Coast, where relatively warm air was located.
As a result, the upper tropospheric flow was from the southwest
across much of the nation.
TEMPERATURE EXTREMES ACROSS THE CONTINENTAL US -- Thursday's
lowest temperature was 8 degrees below zero at Jordan, MT. Thursday's
highest temperature was 86 degrees at Opa Locka, FL.
ALASKAN WEATHER -- High pressure located over northwest
Canada maintained a relatively cold air mass over eastern Alaska.
The western boundary of this air mass was a front that extended
southeastward from the Lisburne Peninsula in northwest Alaska
to the Wrangell Mountains in southeast Alaska. Relatively warm
air was found to the south and west of this front, as southeasterly
winds brought relatively mild air northward. As a result of this
warm air advection, rain fell at Nome, a relatively unusual event.
An occluded front associated with a major storm system in the
western Bering Sea curved southeastward across the central Aleutians.
Farther east, a weak storm system was located just south of the
Alaska Peninsula. These systems produced clouds and rain across
most of the Aleutians, the Alaska Peninsula and the region surrounding
Bristol Bay. Weak high pressure was located across the eastern
Gulf of Alaska, southeast Alaska and the Panhandle. Easterly winds
were found across the North Slope, causing blowing snow at Barrow
and Deadhorse. These strong winds also caused wind-chill equivalent
temperatures to fall to 55 degrees below zero at Barrow. Winds
gusted to as high as 46 mph at Barter Island on Thursday morning.
The lowest overnight temperature in Alaska on Thursday morning
was 27 degrees below zero at Arctic Village, while the mid-afternoon
highest statewide temperature was 50 degrees at Dutch Harbor.
HAWAIIAN WEATHER -- Typical trade wind weather continued
across the 50th State on Thursday as a result of high pressure
to the north of the islands. East to northeast trade winds had
speeds ranging from 10 to 25 mph. A series of high pressure systems
are expected to move eastward across the North Pacific over the
weekend, maintaining the pressure gradient across the islands.
As a result, easterly trade winds will be maintained with speeds
ranging from 10 to 15 mph. Some brief trade showers could fall
on the windward slopes of the mountains, especially at night and
early mornings.
A SOMBER ANNIVERSARY -- Today is the 25th anniversary of
the sinking of the Great Lakes ore carrier, Edmund Fitzgerald,
during a powerful storm on Lake Superior. The National Weather
Service Forecast Office at Marquette, MI has a web page
commemorating the sinking and describing the advances in marine
weather forecasting over the last quarter century.
FULL MOON -- The moon will reach the full moon phase late
tomorrow afternoon at 2115 Z (or 4:15 PM EST or 3:15 PM CST).
The full moon of November is often called the "Frosty Moon"
or "Beaver Moon".
HISTORICAL WEATHER EVENTS - 10 November
From the files of the Aviation Weather Center, Kansas City,
MO and Intellicast
- ...1835...A severe storm crossed the Great Lakes with 19 ships
lost and 254 sailors killed. (Intellicast)
- ...1915...An unusually late season violent F-4 tornado struck
the central Kansas town of Great Bend killing eleven persons along
its 35 mile track. The tornado destroyed 160 homes in Great Bend
killing 11 persons and causing a million dollars damage. Debris
was carried 85 miles. Hundreds of dead ducks dropped from the
sky northeast of the track's end. (The Weather Channel)
- ...1975...Another "freshwater fury" hit the Great
Lakes. A large ore carrier on Lake Superior, the Edmund Fitzgerald,
sank near Crisp Point with the loss of its crew of 29 men. Eastern
Upper Michigan and coastal Lower Michigan were hardest hit by
the storm, which produced wind gusts to 71 mph at Sault Ste Marie,
MI and gusts to 78 mph at Grand Rapids, MI. Severe land and road
erosion occurred along the Lake Michigan shoreline. A popular
hit song by Gordon Lightfoot was inspired by the storm. (David
Ludlum)
- ...1987...A cold front brought snow to the Appalachian Region
and freezing temperatures to the central U.S. Up to nine inches
of snow blanketed Garrett County of extreme western Maryland.
Freezing temperatures were reported as far south as El Paso, TX
and San Angelo, TX. Gale force winds lashed the Middle Atlantic
Coast and the coast of southern New England. Thunderstorms brought
fire quenching rains to Alabama, and produced large hail and damaging
winds to eastern North Carolina. Ahead of the cold front, seven
cities in Florida and Georgia reported record high temperatures
for the date as readings warmed into the 80s. (Storm Data) (The
National Weather Summary)
- ...1988...Strong winds circulating around a deep low pressure
system in southeastern Ontario buffeted the northeastern U.S.,
with the Lower Great Lakes Region hardest hit. Winds in western
New York State gusted to 68 mph at Buffalo, to 69 mph at Niagara
Falls, and to 78 mph at Brockport. Four persons were injured at
Rome, NY when a tree was blown onto their car. (The National Weather
Summary) (Storm Data)
- ...1989...Strong southwesterly winds prevailed along the eastern
slopes of the Rockies in Montana and Wyoming. Winds of 80 to 90
mph prevailed across the northwest chinook zone of Montana, with
gusts to 112 mph. Unseasonably warm weather accompanied the high
winds. Shortly after midnight the temperature at Kalispell, MT
reached a record 59 degrees. Windy and wet weather prevailed across
Washington State. Strong southerly winds gusted to 70 mph at Rattlesnake
Ridge, near Hanford. Six rivers in western Washington State rose
above flood stage between the 9th and the 11th of the month, following
eight days of moderate to heavy rain. Rainfall over the western
slopes of the Cascade Mountains between the 3rd and the 10th ranged
from 14 to 24 inches. High freezing levels also caused the early
snowpack to melt, adding to the runoff in the rain-swollen rivers.
Damage was heaviest in Whatcom County, where the Nooksack River
caused nearly six million dollars damage, mostly to roads and
bridges. (The National Weather Summary) (Storm Data)
- ...1990...A rapidly deepening coastal storm produced severe
weather in North Carolina. A strong F2 tornado touched down on
Hatteras Island. Winds gusted to 78 mph at the airport. (Intellicast)
11 November
- ...1911...The central U.S. experienced perhaps its most dramatic
cold wave of record. During the early morning, temperatures across
the Central Plains ranged from 68 degrees at Kansas City to 4
above at North Platte, NE. In Kansas City, the temperature warmed
to a record 76 degrees by late morning before the arctic front
moved in from the northwest. Skies became overcast, winds shifted
to the northwest, and the mercury began to plummet. By early afternoon
it was cold enough to snow, and by midnight the temperature had
dipped to a record cold reading of 11 degrees above zero. Oklahoma
City also established a record high of 83 degrees and record low
of 17 degrees by midnight that same day (11/11/11), followed by
14 degrees, another record low, by the next morning. In southeastern
Kansas, the temperature at Independence plunged from 83 degrees
to 33 degrees in just one hour. The arctic cold front produced
severe thunderstorms and tornadoes in the Mississippi Valley,
a blizzard in the Ohio Valley, and a dust storm in Oklahoma. On
this 11/11/11 date, Janesville, WI was hit by an F4 tornado killing
9 and injuring 50. Within an hour of the tornado, the survivors
were digging out in blizzard conditions and shivering in zero
temperatures. (David Ludlum) (The Weather Channel) (The Kansas
City Weather Almanac) (Intellicast)
- ...1940...The "Armistice Day" storm, one of the
most powerful and destructive winter storms on record, raged across
the Great Lakes Region and the Upper Midwest. A band of heavy
snow fell, with 26.6 inches at Collegeville, MN and 16.2 inches
at Minneapolis, MN. Winds gusted to over 60 mph. A blizzard left
49 dead in Minnesota, and gales on Lake Michigan caused ship wrecks
resulting in another 59 deaths. Up to seventeen inches of snow
fell in Iowa, and at Duluth, MN the barometric pressure reached
28.66 inches. The blizzard claimed a total of 154 lives, and killed
thousands of cattle in Iowa. Whole towns were isolated by huge
snowdrifts. (David Ludlum) (Intellicast)
- ...1955...An early arctic outbreak set many November temperature
records across Oregon and Washington. The severe cold damaged
shrubs and fruit trees. Many new temperature records were set
as temperatures plunged to near zero in western Washington, and
dipped to 19 degrees below zero in the eastern part of the state.
(David Ludlum)
- ...1987...A deepening low pressure system brought heavy snow
to the east central U.S. The "Veteran's Day storm" produced
up to 17 inches of snow in the Washington, DC area snarling traffic
and closing schools and airports. Afternoon thunderstorms produced
five inches of snow in three hours. This amount of snow is rare
in winter let alone the middle of fall. Thunder and lightning
accompanied the snow for several hours. Gale force winds lashed
the Middle and Northern Atlantic Coast. Norfolk, VA reported their
earliest measurable snow in 99 years of records. (Storm Data)
(The National Weather Summary)
- ...1988...Low pressure brought snow to parts of the Rocky
Mountain Region. Totals in the San Juan Mountains of southwestern
Colorado ranged up to 10 inches at Summitville. Evening thunderstorms
produced large hail in central Oklahoma and north central Texas.
(The National Weather Summary) (Storm Data)
- ...1989...Veteran's Day was an unseasonably warm one across
much of the nation east of the Rockies. Temperatures warmed into
the 70s and 80s from the Southern and Central Plains to the southern
half of the Atlantic coast. Thirty-four cities reported record
high temperatures for the date, including Saint Louis, MO with
a reading of 85 degrees. Calico, AR and Gilbert, AR reported record
highs of 87 degrees. (Storm Data) (The National Weather Summary)
- ...1991...Thunderstorms dumped golfball sized hail at Montyville
and Norwich in southeastern Connecticut during the early morning
hours. (Intellicast)
12 November
- ...1906...The mercury soared to 106 degrees at Craftonville,
CA, a November record for the U.S. (The Weather Channel)
- ...1959...Between Noon on the 11th and Noon on the 12th, a
winter storm buried Helena, MT under 21.5 inches of snow, which
surpassed their previous 24 hour record by seven inches. (The
Weather Channel)
- ...1968...New England was battered by the third severe coastal
storm in only 5 days. An intense low crossed Long Island and produced
wind gusts to 100 mph at Block Island, RI. Tides ran 5 to 10 feet
above normal in some places with severe coastal flooding and damage.
Rockland, ME recorded a wind gust of 86 mph. Winds reached 90
mph in Massachusetts. Up to 10 inches of snow fell at some of
the higher elevations, bringing the totals for the three storms
as high as 60 inches. (David Ludlum) (Intellicast)
- ...1974...A great Alaska storm in the Bering Sea caused the
worst coastal flooding of memory at Nome, AK with a tide of 13.2
feet. The flooding caused 12 million dollars damage, however no
lives were lost. (David Ludlum)
- ...1980...A fringe rain band from Hurricane Jeannie in the
Gulf of Mexico let loose a deluge of 23.38 inches of rain in 24
hours at Key West, FL, an all-time 24 hour record. (Intellicast)
- ...1987...Heavy snow spread across much of New England. Totals
in Massachusetts ranged up to 14 inches in Plymouth County. The
seven inch total at the Logan Airport in Boston was their highest
of record for so early in the season, and the 9.7 inch total at
Providence, RI was a record for November. Roads were clogged with
traffic and made impassable as snowplow operators were caught
unprepared for the early season snowstorm. (Storm Data) (The National
Weather Summary)
- ...1988...Thunderstorms developing ahead of a cold front produced
severe weather in the Lower Mississippi Valley during the afternoon
and early evening hours. Thunderstorms produced wind gusts to
80 mph at Bovina, MS. Morning thunderstorms drenched Atlanta,
TX with more than four inches of rain. (The National Weather Summary)
(Storm Data)
- ...1989...Thirty-three cities reported record high temperatures
for the date as readings soared into the 70s and 80s from the
Southern and Central Plains to the Southern and Middle Atlantic
Coast Region. The afternoon high of 80 degrees at Scottsbluff,
NE was a record for November, and highs of 76 degrees at Rapid
City, SD and 81 degrees at Chattanooga, TN were the warmest of
record for so late in the season. (The National Weather Summary)
