AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LA CROSSE WI
309 PM CST FRI JAN 1 2010
.SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT
THE MAJOR CONCERN FOR TONIGHT AND SATURDAY MORNING WILL BE THE
WIND CHILLS. UNDER CLEAR SKIES AND A DRY AIR MASS...TEMPERATURES
SHOULD QUICKLY FALL OVERNIGHT INTO THE 10 TO 20 BELOW RANGE. WITH
WIND SPEEDS OF 10 TO 15 MPH...THE WIND CHILLS WILL LIKELY FALL
INTO THE 30 TO 40 BELOW RANGE ACROSS THE HIGHER TERRAIN AREAS OF
SOUTHEAST MINNESOTA AND NORTHEAST IOWA...AND INTO THE 25 TO 35 BELOW
RANGE ACROSS THE REMAINDER OF THE AREA. DUE TO THIS...WE WILL BE
SHORTLY ISSUING WIND CHILL ADVISORIES AND WARNINGS. THESE
BITTERLY TO DANGEROUSLY COLD WIND CHILLS WILL LIKELY LINGER
THROUGH AT LEAST 9 AM SATURDAY MORNING.
LOOKING AT THE TEMPERATURES UPSTREAM IN THE VICINITY OF THE HIGH
PRESSURE SYSTEM...THEY ARE STILL IN THE TEENS BELOW ZERO. SINCE
THIS HIGH WILL BE MOVING SOUTHEAST TOWARD THE AREA THIS WEEKEND...
THERE ARE CONCERNS THAT THE MOS TEMPERATURES FOR TONIGHT THROUGH
SUNDAY MORNING MAY BE A BIT TOO WARM. THIS IS NOT THAT UNCOMMON
WITH THESE ARCTIC AIR MASSES. AS A RESULT...THE MAXIMUM/MINIMUM
TEMPERATURE GRIDS WERE ADJUSTED COOLER. THEY ARE NOW IN MORE IN
LINE WITH THE TWO METER TEMPERATURE PLUMES AND THE COLDER GEM
VALUES WHICH SEEM TO BE VERIFYING A BIT BETTER UPSTREAM.
ON SATURDAY NIGHT...THE MINIMUM TEMPERATURES WILL LIKELY BE THE
COLDEST OF THE WEEKEND. THIS IS DUE TO THE ARCTIC HIGH PRESSURE
SYSTEM BEING NEARLY OVERHEAD. HOWEVER THIS HIGH WILL ALSO CAUSE
OUR WINDS TO BECOME VERY LIGHT AND THIS WILL REDUCE THE COOLING
EFFECT FROM THE WIND.
ON SUNDAY NIGHT...A SHORT WAVE TROUGH WILL BE MOVING SOUTHWEST
ACROSS THE NORTHERN GREAT LAKES. ON BOTH THE THE 01.00Z AND 01.12Z
MODELS...IT CONTINUES TO APPEAR THAT THIS SYSTEM WILL CAUSE AN
INCREASE IN THE CLOUDS ACROSS NORTH CENTRAL AND CENTRAL WISCONSIN.
AFTER SOME DISCUSSION...IT WAS DECIDED TO INCREASE THESE CLOUD
PERCENTAGES BY 10 TO 20 PERCENT ACROSS THESE AREAS. IN
ADDITION...THIS SYSTEM WILL BRING SOME SLIGHTLY WARM AIR INTO THE
REGION. AS A RESULT...OVERNIGHT LOW TEMPERATURES MAY NOT BE QUITE
AS COLD AS THEY WERE OVER THE WEEKEND.
.LONG TERM...MONDAY THROUGH FRIDAY
THE 01.00Z AND 01.12Z MODELS ARE STILL SHOWING THAT A SHORT WAVE
TROUGH WILL ROTATE SOUTHWEST ACROSS THE AREA ON MONDAY. AT THIS
TIME...IT ONLY LOOKS LIKE THIS SYSTEM WILL BRING SOME MID AND HIGH
CLOUDS TO THE AREA. THERE WAS SOME DISCUSSION OF INCREASING THE
CLOUDS TO MOSTLY CLOUDY ACROSS WESTERN WISCONSIN...AND PARTLY
CLOUDY ACROSS SOUTHEAST MINNESOTA AND NORTHEAST IOWA. HOWEVER
THERE WAS SOME CONCERN THAT THIS WAVE MAY BE A BIT TOO FAR WEST...
SO IT WAS THE CONSENSUS TO JUST INCREASE THE CLOUD COVERAGE BY
10 TO 20 PERCENT.
WITH THE MODELS CONTINUING TO SHOW THAT A TROUGH WILL MOVE OVER
TOP OF THE WESTERN NORTH AMERICAN RIDGE AND THEN MOVE SOUTHEAST
THROUGH THE UPPER MISSISSIPPI RIVER VALLEY FROM WEDNESDAY THROUGH
THURSDAY...A SLIGHT CHANCE OF SNOW WAS ADDED TO THE GRIDS. IF THIS
TREND CONTINUES...THESE SNOW CHANCES WILL LIKELY HAVE TO BE RAISED
FURTHER. AT THIS TIME...THE SNOW AMOUNTS LOOK TO BE A HALF INCH OR
LESS. BEHIND THIS WAVE...THERE WILL BE A 1054 MB HIGH BUILDING
SOUTHWARD INTO THE NORTHERN PLAINS. THIS WILL BRING ANOTHER SURGE
OF ARCTIC AIR INTO THE REGION.
&&
.AVIATION...TONIGHT AND SATURDAY
ARCTIC HIGH PRESSURE WILL BUILD SOUTHEAST FROM THE NORTHERN PLAINS
TONIGHT. THIS WILL RESULT IN SUBSIDENCE ACROSS THE AREA WITH CLEAR
SKIES EXPECTED THROUGH THE TAF PERIOD. WITH THE CENTER OF THE HIGH
STILL WEST OF THE LOCAL AREA...NORTHWEST WINDS WILL CONTINUE IN THE
8 TO 12 KNOT RANGE THROUGH 18Z SATURDAY.
