FORECAST DISCUSSION FOR ROUTINE AFTERNOON FORECAST ISSUANCE

.SHORT TERM...TONIGHT AND WEDNESDAY
ISSUED AT 224 PM CST TUE DEC 30 2014

COLDEST AIR OF THE SEASON SO FAR WILL BE THE MAIN CONCERN THROUGH
WEDNESDAY...WITH WIND CHILL HEADLINES POSSIBLE. OTHERWISE...THE
COLD BUT DRY PATTERN CONTINUES TO HOLD OVER WISCONSIN.

NOT MUCH TO TALK ABOUT WEATHER-WISE IN THE SHORT TERM WITH ZONAL
FLOW ALOFT KEEPING THINGS QUIET. WITH VERY DRY AIR IN PLACE OVER
THE STATE AND ZERO FORCING ALOFT...PRECIPITATION CHANCES THROUGH
WEDNESDAY ARE NIL. SKIES SHOULD REMAIN MOSTLY CLEAR THROUGH
TONIGHT BEFORE A SHORTWAVE SWINGS INTO THE UPPER MIDWEST WEDNESDAY
AND CLOUDS INCREASE THROUGH THE DAY. NO PRECIP IS EXPECTED WITH
THIS FEATURE DESPITE IT BEING ON THE STRONGER SIDE AS LOW LEVELS
WILL REMAIN VERY DRY.

THE MAIN STORY THROUGH WEDNESDAY WILL BE THE TEMPERATURES AND WIND
CHILLS. LOWS TONIGHT WILL BE COLDER THAN LAST NIGHT AS VERY COLD
AIR REMAINS IN PLACE OVER THE REGION. WITH CLEAR SKIES...PLUMMET
AFTER SUNSET. AND UNLIKE THIS PREVIOUS NIGHT...WINDS WILL NOT BE
LIGHT. WITH TEMPERATURES FALLING WELL BELOW ZERO THROUGH OUT MUCH
OF THE CWA...ANY WIND WILL ALREADY PUT MOST LOCATIONS IN WIND
CHILL ADVISORY CRITERIA. GUIDANCE INCREASED WINDS THROUGH THE
OVERNIGHT WITH NOT MUCH CHANGE TO LOW TEMPERATURES. GIVEN THE NEW
GUIDANCE...WILL BE REISSUING A WIND CHILL ADVISORY FOR TONIGHT FOR
NORTH CENTRAL WISCONSIN. WHILE TO NIGHTS ADVSY EXTENDS A BIT
FURTHER EAST...STILL DONT THINK EASTERN WISCONSIN WILL REACH
CRITERIA. IT WILL BE PLENTY COLD FOR THEM...BUT WITHOUT SNOW COVER
THEY WILL STALL OUT ON THE OVERNIGHT TEMPERATURE PLUNGE.

WHILE WEDNESDAY WILL BE A BIT WARMER DUE TO WAA OUT OF
CANADA...GUSTY WSW WINDS WILL MAKE IT FEEL COLDER THAN THE
OUTSIDE TEMP.

.LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY
ISSUED AT 224 PM CST TUE DEC 30 2014

THE DEEP LOW PRESSURE SYSTEM OVER HUDSON BAY WILL CONTINUE TO DRAW
COLD YUKON AIR INTO THE GREAT LAKES REGION AND GENERATE GUSTY
WEST-NORTHWEST WINDS INTO THURS MORN. WINDS WILL SLACKEN AND TEMPS
WILL WARM INTO THE LOW 20S IN THE FOX VALLEY DURING THE DAY THURS
AS THE TRAILING END OF A SECONDARY COLD FRONT MOVES IN AND WASHES
OUT OVER THE REGION. LOW PRESSURE DEVELOPING OVER THE NORTHERN
ROCKIES AT THAT TIME WILL STEP OUT INTO THE MIDWEST AND
STRENGTHEN...TAPPING A LITTLE BIT OF GULF OF MEXICO MOISTURE AND
BRINGING A DECENT CHANCE FOR SNOW IN NORTHEAST WI SATURDAY
AFTERNOON THRU SUNDAY MORNING. THE LOW WILL MOVE OUT TOWARD THE
NORTHEAST QUICKLY. MODELS ARE IN REASONABLY GOOD AGREEMENT ON
TIMING AND INTENSITY FOR THIS EVENT.
