AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI

.VERY SHORT TERM...TONIGHT AND FRIDAY.

MAIN AREA OF THUNDERSTORMS WILL EXIT SOUTHEAST WI SHORTLY AFTER 00Z
THIS EVENING. ANY LINGERING SHOWERS WILL BE DISSIPATING AS WELL.
THANKFULLY...THE STORMS ARE GOING OVER AREAS IN EAST CENTRAL AND
SOUTHEAST WI THAT DID NOT GET AS HEAVY OF RAINFALL AMOUNTS OVER THE
WEEKEND.

SKIES SHOULD CLEAR TONIGHT...BUT FOG NOT AN ISSUE DUE TO
THE STRONGER NORTHWEST WINDS JUST ABOVE THE SURFACE. LOWERED MIN
TEMPS FOR TONIGHT FROM THE PREVIOUS FORECAST INTO THE LOWER 60S
GIVEN THE 925MB TEMPS OF 18-20C AND A WEAK TO MODERATE INVERSION.

THE CENTER OF AN UPPER LOW WILL DRIFT OVER THE GREAT LAKES REGION ON
FRIDAY. A SHORTWAVE ROTATING AROUND IT WILL SWING ACROSS WISCONSIN
DURING THE PEAK AFTERNOON HEATING HOURS. STEEP LOW LEVEL LAPSE RATES
WILL LEAD TO WIDESPREAD CUMULUS. THERE WILL BE JUST ENOUGH CAPE TO
SUPPORT SCATTERED THUNDERSTORMS...BUT NOT EXPECTING SEVERE.
WELL-MIXED LOW LEVELS WILL ALLOW FOR GUSTY NORTHWEST WINDS DURING
THE AFTERNOON. WIND GUSTS IN THE 20 TO 25 MPH RANGE ARE LIKELY.

HIGHS WILL BE COOLER TOMORROW IN THE MID 70S WITH AFTERNOON CLOUDS
AND LOWER 925MB TEMPS IN THE 16 TO 18C RANGE.

.SHORT TERM...FRIDAY NIGHT THROUGH SUNDAY.

SEVERAL MID-LEVEL SHORT WAVES WILL ROTATE SOUTHWARD ACROSS SOUTHERN
WI FRIDAY NIGHT AND SATURDAY AS LONG WAVE TROUGH CONTINUES TO
AMPLIFY ACROSS THE CENTRAL/EASTERN GTLAKES AND EASTERN CONUS.
STRONGEST OMEGA AND BEST LAYER Q-VECTOR CONVERGENCE ARRIVES SAT MRNG
AND EARLY AFT WITH LAST PASSING WAVE. LAYER RH GREATER THAN 90
PERCENT EXTENDS WELL INTO THE MID-LAYERS AT THIS TIME.  THEREFORE
WILL CONTINUE LIKELY WORDING FOR SHRA AND ISOLD T ON SAT WITH
DECREASING TREND LATER SAT AFTN AND EARLY EVE AS SHORT WAVE SLIDES
SOUTH OF AREA.  SURGE OF DRIER AIR AND INCREASING SUBSIDENCE ARE
EXPECTED TO END THE PRECIP THREAT SAT NIGHT AND SUNDAY AS LOW
PRESSURE TROUGH SETTLES OVER THE OH/TN VALLEY REGION.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY.

CUTOFF UPPER LOW OVER TN/OH VALLEY REGION AND CENTRAL GTLAKES BEGINS
TO RETROGRADE SLOWLY WESTWARD EARLY NEXT WEEK IN RESPONSE TO
BUILDING WESTERN ATLANTIC HIGH PRESSURE RIDGE. EXTENDED GUIDANCE IN
REASONABLE AGREEMENT ON THIS SCENARIO.  UPPER LOW SHIFTS WWD INTO
CENTRAL MS VALLEY REGION BY TUE WITH LONG WAVE TROFFING THEN
REMAINING FAIRLY STATIONARY ACROSS CENTRAL CONUS THROUGH THE END OF
NEXT WEEK...WHILE UPSTREAM AND DOWNSTREAM BLOCKING RIDGES REMAIN
OVER WESTERN THIRD OF CONUS AND OVER WESTERN ATLANTIC.

WITH LOW TO MID LEVEL CONVERGENCE AND GRADUALLY INCREASING LOW LEVEL
HUMIDITY ANTICIPATED...EXPECT THE CHANCE FOR CONVECTION TO RETURN TO
SOUTHERN WI AROUND TUESDAY AND CONTINUE THROUGH THE 4TH.  THINKING
BEST TIMING FOR CONVECTION WILL BE IN THE AFTERNOON AND EVENING ON
THESE DAYS DURING PEAK HEATING.
