AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
259 PM CDT WED MAR 24 2010

.SHORT TERM...TONIGHT AND TOMORROW.

LATEST RUC ANALYSIS AND VIS/IR/WV IMAGERY SHOW SPLIT FLOW CONVERGING
AROUND THE GREAT LAKES REGION.  SOUTHERN STREAM SHORTWAVE OVER NEW
MEXICO IS SENDING AN EXPANSIVE CIRRUS SHIELD OVER THE SOUTHERN HALF
OF THE STATE THIS AFTERNOON.  LOW LEVELS REMAIN DRY HOWEVER...WITH
DEWPOINTS FALLING INTO THE MID TEENS OVER CENTRAL WISCONSIN.
FARTHER TO THE NORTH...STRONG SHORTWAVE OVER MANITOBA IS PUSHING AN
ARCTIC COLD FRONT TO THE SOUTH OVER THE US-CANADIAN BORDER. BITTERLY
COLD AND DRY AIR IS POISED TO SHIFT SOUTH BEHIND THE FRONT...WHICH
IS DUE TO ARRIVE LATE TONIGHT AND TOMORROW.  AS A RESULT...SMALL
PRECIP CHANCES...AND TEMPS AND CLOUDS ARE THE MAIN FORECAST
CHALLENGES.

TONIGHT...THE SHORTWAVE ACROSS THE SOUTHERN PLAINS WILL TRACK TO THE
EAST WHICH WILL SHIFT THE CONVERGENT UPPER LEVEL FLOW CURRENTLY
PRESENT ACROSS THE SOUTHERN HALF OF THE STATE TO THE SOUTHEAST.  AS
A RESULT...WILL SEE THE BLANKET OF CIRRUS ERODE ACROSS CENTRAL AND
EAST-CENTRAL WISCONSIN...LEAVING MOSTLY CLEAR SKIES BY LATE IN THE
EVENING.  MEANWHILE...STRONG SHORTWAVE WILL SWING ACROSS ONTARIO AND
SEND AN ARCTIC COLD FRONT ACROSS THE REGION AFTER MIDNIGHT.  VERY
LITTLE MOISTURE ALONG THE FRONT ACCORDING TO PROGGED SOUNDINGS...AS
MID-LEVEL MOISTURE SEEMS TO GET STRETCHED.  MAY SEE AN ISOLATED
FLURRY ACROSS N-C WISCONSIN WITH SOME MINOR LAKE SUPERIOR
CONTRIBUTION AS DELTA T/S GROW TO THE MID TEENS.  OTHERWISE...THE
FRONT MAY ONLY CONTAIN SOME SCT LOW CLOUDS ALONG WITH INCREASING NW
WINDS. WENT A COMBO OF THE PREVIOUS GRID AND SREF FOR THE
LOWS...WHICH WILL RANGE FROM AROUND 20 NORTH TO MID 30S SE.

TOMORROW...ARCTIC HIGH PRESSURE WILL BUILD IN...ONCE THE FRONT
DEPARTS IN THE MORNING.  VERY DRY AIR WILL ARRIVE BEHIND THE FRONT
WITH 850-700MB RH/S BETWEEN 15-25 PCT.   DESPITE THE INSTABILITY
OVER LAKE SUPERIOR...THE DRY AIR SHOULD PREVENT ANY LAKE EFFECT
PRECIP...THOUGH MAY SEE SOME SHALLOW LAKE CLOUDS ACROSS NORTHERN
WISCONSIN IN THE MORNING.  THESE CLOUDS SHOULD MIX OUT IN THE
AFTERNOON WITH A RELATIVELY STRONG MARCH SUN AND DECENT WINDS
PROVIDING GOOD MIXING.  TEMPERATURES WILL BE RETURNING TO MORE OF A
SEMBLANCE OF WINTER CONDITIONS.  NEARLY ALL GUIDANCE WENT COLDER
WITH THE 12Z RUNS...AND LOW LEVEL TEMPERATURE DISTRIBUTIONS SUGGEST
THE COLDEST TEMPS WILL RESIDE ACROSS N-C AND FAR NORTHEAST
WISCONSIN.  DROPPED HIGHS A FEW DEGREES...AND WILL RANGE FROM AROUND
30 NORTH...TO THE MID 40S OVER CENTRAL WISCONSIN.  THE FOX VALLEY
WILL FIND IT TOUGH TO GET OUT OF THE MID 30S WITH GUSTY NE WINDS
FUNNELING DOWN THE BAY.

.LONG TERM...FRI THRU NEXT WED.

NOT MUCH CHANGE IN PREV FORECAST AS SRN STREAM REMAINS ACTIVE INTO
FIRST PART OF EXTENDED FORECAST PERIOD. SOME DIFFERENCES IN
MODELS...ESP BETWEEN 28/12Z GFS AND 28/00Z ECMWF WITH RESPECT TO
SPEED OF LATE WEEKEND SRN STREAM SYSTEM...BUT SINCE BULK OF IT WILL
STAY S OF FORECAST AREA...NOT MUCH IMPACT HERE. HOWEVER...WEAK
SHRTWV TROF IN NRN STREAM AT AROUND SAME TIME COULD BRING LIGHT
PRECIP LATE SAT OR SAT NIGHT.

DIFFERENCES ALSO SEEN IN AMPLITUDE OF RIDGING ACROSS MIDDLE OF COUNTRY
TOWARD END OF PERIOD. THIS HAS OBVIOUS RAMIFICATIONS ON TEMP
FORECAST...ALTHOUGH BOTH SOLUTIONS INDICATE TEMPS WELL ABOVE NORMS
BY MID WEEK.
&&

.AVIATION...BKN MVFR CONDITIONS ARE POSSIBLE AT RHI LATE TONIGHT
WHEN AN ARCTIC COLD FRONT ARRIVES.  OTHERWISE...VFR CONDITIONS ARE
EXPECTED THROUGH THE TAF PERIOD...WITH SOME POSSIBLE SCT STRATO-CU
AND GUSTY WINDS ARRIVING TONIGHT.
&&

.GRB WATCHES/WARNINGS/ADVISORIES...
NONE.
