...FREEZE WARNING REMAINS IN EFFECT UNTIL 7 AM CDT WEDNESDAY...

A FREEZE WARNING REMAINS IN EFFECT UNTIL 7 AM CDT WEDNESDAY. 

A COOL CANADIAN AIR MASS...COMBINED WITH LIGHT WINDS AND CLEAR TO
PARTLY CLOUDY SKIES WILL ALLOW TEMPERATURES TO FALL BELOW
FREEZING OVER MUCH OF THE AREA TONIGHT. OVERNIGHT LOWS ARE
EXPECTED TO RANGE FROM THE MIDDLE 20S IN FAR NORTHERN WISCONSIN
TO THE UPPER 20S AND LOWER 30S FARTHER SOUTH. SLIGHTLY MILDER
TEMPERATURES ARE EXPECTED NEAR THE LAKE MICHIGAN SHORELINE...SO
A WIDESPREAD FREEZE IS NOT LIKELY THERE. IN ADDITION...INCREASING
HIGH CLOUDS OVER CENTRAL WISCONSIN COULD PREVENT A WIDESPREAD
FREEZE THERE.

A FREEZE WARNING MEANS SUB-FREEZING TEMPERATURES ARE IMMINENT OR
HIGHLY LIKELY. THESE CONDITIONS WILL DAMAGE OR KILL EARLY SEASON
CROPS AND OTHER SENSITIVE VEGETATION. PLANTS WHICH ARE STILL IN
POTS SHOULD BE BROUGHT INTO THE HOUSE OR GARAGE FOR PROTECTION.
STORES WITH LARGE AMOUNTS OF ANNUAL PLANTS OUTSIDE COULD HAVE
SIGNIFICANT LOSSES IF THE PLANTS ARE NOT PROTECTED.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
223 PM CDT TUE MAY 27 2008

.SHORT TERM...TONIGHT AND WEDNESDAY. OBVIOUS MAIN CHALLENGE
CENTERS ON ISSUANCE OF FROST OR FREEZE HEADLINES OVERNIGHT.
THIS AFTERNOON THE SURFACE RIDGE AXIS EXTENDS FROM SRN CANADA TO
SE WI WITH UPPER LEVEL CI BRUSHING PARTS OF CENTRAL AND EAST
CENTRAL AT TIMES. WHILE FREEZING TEMPOS A SLAM DUNK OVER NRN WI
TNT...WENT BACK AND FORTH WITH A FROST OR FREEZE OVER THE SOUTH.
DECIDED TO KEEP THE HEADLINES SIMPLE FOR THE TV FOLKS AND ISSUED A
WARNING FOR THE ENTIRE AREA DUE TO RATHER COOL START THIS
AFTERNOON AND SURFACE DEWPOINTS IN THE UPPER 20S.  WILL EVEN
INCLUDE THE LAKESHORE COUNTIES AS TEMPERATURES STARTING COOL
AROUND 50.  PRESSURE GRADIENT THIS EVENING MAY KEEP TEMPS IN CHECK
OVER ERN WI AND ALONG THE LAKE...BUT ANTICIPATE TEMPS FOR INLAND
REGIONS TO PLUMMET AS HIGH BUILDS IN AND WINDS CALM.  AS MENTIONED
SRN PORTIONS MAY SEE A WIDER RANGE IN LOW TEMPS TNT DUE TO THE
CI CLOUDS AND PERHAPS A FROST ADVISORY WOULD HAVE WORKED OUT JUST
AS WELL...BUT CONSIDERING MUCH OF THE FORECAST AREA EXPECTING NEAR
RECORD LOWS TNT...FREEZING WARNING PREFERRED.

QUIET WEATHER FOR WEDNESDAY AS HIGH PRESSURE SYSTEM DOMINATES THE
REGION.

.LONG TERM...WED NGT THRU NXT TUE. AFTER A COOL MID
WEEK...CHALLENGE THEN TURNS TO CHC OF PCPN LATER IN THE WEEK WITH
THE RETURN FLOW AS THE HIGH PRESSURE SYSTEM DROPS SOUTHEAST. TREND
OF THE MODEL RUNS IS FOR A FASTER ARRIVAL OF THE WAA RETURN FLOW
FOR THURSDAY NIGHT AND INTO FRIDAY. INCREASED POPS THURSDAY NIGHT
AS A RESULT. TRENDS ALSO SUGGEST SURFACE LOW AND WARM FRONT WILL
TRACK SOUTH OF THE FORECAST AREA FROM THURSDAY NIGHT INTO
FRIDAY...BUT CLOSE ENOUGH TO PARTS OF CENTRAL AND EAST CENTRAL
WISCONSIN FOR PERHAPS STRONGER STORMS ON FRIDAY.

AFTER THE PASSAGE OF THE FRONTAL SYSTEM ON FRIDAY...NORTHWEST FLOW
WITH SUBTLE BOUNDARIES ON SATURDAY PROVIDE SOME POTENTIAL FOR
CONVECTION...BUT WILL LEAVE DRY OR LOW CHC POPS.

MDM RANGE SOLUTIONS DIVERT LATER SUNDAY INTO THE NEW WORK
WEEK...RANGING FROM A RIDGE OVER THE REGION AS PER DGEX...TO A
STRONG CANADIAN CDFNT DROPPING INTO THE NORTH MONDAY NIGHT AS PER
GFS AND THEN SAGGING SOUTH OVER THE REGION TUESDAY.
