AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
246 PM CST WED JAN 19 2011

.SHORT TERM...TONIGHT INTO THURSDAY.

SHORT WAVE THAT BROUGHT LIGHT SNOW/FLURRIES TO THE AREA THIS
MORNING IS NOW PULLING EAST INTO LAKE MICHIGAN. HIGH PRESSURE AT
THE SURFACE TO SHIFT EAST THROUGH SOUTHERN WI/NRN IL TONIGHT.
MODELS ALL SUGGEST SOME GRADIENT REMAINING OVERNIGHT. CLOUDS
CLEARED LATE THIS MORNING...EARLY AFTERNOON ONLY TO BE REPLACED BY
CONVECTIVE CU FOR THE AFTERNOON. EXPECT SOME CLEARING THIS EVENING
AS CURRENT CU DISSIPATES...THOUGH STILL SEE CLOUDS UPSTREAM. IN
ADDITION WAA AHEAD OF NEXT SHORT WAVE TO MOVE THROUGH OVERNIGHT.
WILL SIDE WITH EARLIER FORECAST AND GO TOWARDS WARMER GUIDANCE...A
BIT LOWER THAN EARLIER FORECAST PACKAGE.

ARCTIC COLD FRONT WILL ENTER THE FORECAST AREA THURSDAY AFTERNOON.
EXPECT SOME LIGHT SNOW AND FLURRIES WITH ITS PASSAGE. MODELS
PRETTY CONSISTENT ON COLD AIR ENTERING LATER IN THE AFTERNOON.
WILL NOT SHOW ANY FALLING TEMP TREND AT THIS TIME. THOUGH LATEST
ECMWF CAME IN A BIT FASTER...NAM USUALLY BETTER WITH COLD AIR.

.LONG TERM...THURSDAY NIGHT THROUGH NEXT WEDNESDAY.

UPPER LEVEL FLOW WAS FORECAST TO RETAIN ITS GENERAL PATTERN OF A RIDGE
IN THE EASTERN PACIFIC AND TROUGH OVER THE CENTRAL/EASTERN CONUS.
FLOW ACROSS WISCONSIN BECOMES NORTHWEST LATE THIS WEEK BEFORE
BECOMING MORE ZONAL DURING THE EARLY PART OF NEXT WEEK. CLIPPER
TYPE SYSTEMS IN THE NORTHERN BRANCH OF THE UPPER FLOW MAY BRING A
CHANCE OF SNOW TO THE REGION WHILE MORE SIGNIFICANT SYSTEMS IN THE
AMPLIFIED SOUTHERN BRANCH REMAIN SOUTH OF THE AREA. NO MAJOR
SYSTEMS WERE FORECAST TO REACH THE FORECAST AREA THROUGH THE
MIDDLE OF NEXT WEEK...BUT SOME LAKE EFFECT SNOW SHOWERS ARE POSSIBLE
AT TIMES WITH COLD AIR PASSING OVER LAKE SUPERIOR.

NORTHWEST FLOW WILL RESULT IN RATHER COLD TEMPERATURES THURSDAY
NIGHT AND ENOUGH WIND IS EXPECTED THAT WIND CHILLS COULD APPROACH
WARNING CRITERIA IN PARTS OF THE CWA. EXPECT A GRADUAL WARM UP AS
THE UPPER FLOW BECOMES MORE ZONAL. BUT IT WILL PROBABLY TAKE UNTIL
THE MIDDLE OF NEXT WEEK BEFORE TEMPERATURES REACH SEASONAL
NORMALS.
&&
