AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREEN BAY WI
309 PM CDT THU MAY 30 2013

FORECAST DISCUSSION FOR ROUTINE AFTERNOON FORECAST ISSUANCE

.SHORT TERM...TONIGHT AND FRIDAY
ISSUED AT 308 PM CDT THU MAY 30 2013

CURRENT SEVERE TO NEAR-SEVERE TSTMS COUPLED WITH ANOTHER SVR
THREAT ON FRI REMAINS THE MAIN FOCAL POINT OVER THE NEXT 24 HOURS.

THE 19Z MSAS SFC ANALYSIS SHOWED A STRONG AREA OF LOW PRES OVER
N-CNTRL SD WITH A WARM FRONT EXTENDED E-NE THRU UPR MI. A SURFACE
TROF STRETCHED SEWD FROM THE LOW PRES TOWARD NW MO. CLUSTERS OF
TSTMS COVER MOST OF THE REGION WITH SOME OF THESE STORMS TURNING
SEVERE. EXPECT SVR RISK TO CONT INTO EARLY EVENING AS INDIVIDUAL
SHORTWAVES ROTATE NEWD AROUND A NEGATIVELY-TILTED UPR TROF OVER
THE CNTRL CONUS AND SHEAR VALUES BEGIN TO INCREASE INTO A
MODERATELY UNSTABLE AIR MASS OVER WI.

ONGOING CONVECTION SHOULD CARRY OVER INTO AT LEAST THE EVENING
HOURS AS ANOTHER SHORTWAVE LIFTS NE INTO THE WRN GREAT LAKES.
WHILE INSTABILITY MAY WEAKEN A BIT UPON SUNSET...SHEAR IS FCST TO
INCREASE WHICH WOULD HELP TO MAINTAIN UPDRAFT POTENTIAL AND
ADDITIONAL TSTMS. THE THREAT FOR MORE SHWRS/ISOLATED TSTMS TO
PERSIST THRU THE OVRNGT HOURS AS THE NEGATIVELY-TILTED UPR TROF
ROTATES NEWD THRU THE MIDWEST. ANY SEVERE WEATHER HOWEVER SHOULD
DIMINISH BY THE MIDNGT HOUR AS THE ATM STABILIZES BEHIND THE
INITIAL STORMS AND NOCTURNAL COOLING TAKES PLACE.

MUCH LIKE TODAY...TSTM POTENTIAL FOR FRI WL COME DOWN TO HOW MUCH
LINGERING CLOUD COVER REMAINS OVER THE REGION. IF WE CAN BREAK OUT
OF THE CLOUDS AND ALLOW FOR AT LEAST SOME DIURNAL HEATING...SEVERE
POTENTIAL WOULD INCREASE FOR THE AFTERNOON HOURS AS CAPES COULD
REACH 1500 J/KG AND 0-6 KM BULD SHEAR RISES TO >50 KTS. COULD BE
ANOTHER ACTIVE WEATHER DAY SOMEWHERE IN WI WITH MORE SEVERE
WEATHER EXPECTED. MAX TEMPS SHOULD BE A FEW DEGS COOLER THATN
TODAY WITH MORE CLOUDS AROUND AND COOLER AIR ALOFT AS THE MAIN UPR
LOW MOVES TOWARD THE UPR MS VALLEY.

.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY
ISSUED AT 308 PM CDT THU MAY 30 2013

MAIN FCST CONCERNS ARE CONVECTIVE TRENDS AND SVR TSTM THREAT
FRIDAY EVENING...PCPN TRENDS FOR THE REST OF THE WEEKEND...THEN
DRY CONDITIONS EARLY NEXT WEEK.

WILL KEEP THIS BRIEF...AS MAIN FOCUS IS ON THIS AFTERNOONS SEVERE
POTENTIAL AND WARNINGS.

HAVE SOME CONCERN ABOUT ANOTHER POSSIBLE BOUT OF SVR TSTMS LATE
FRIDAY AFTERNOON/EVG. MODERATE INSTABILITY IS EXPECTED TO DEVELOP
LATE FRIDAY AFTERNOON/EARLY EVG. SHEAR IS EXPECTED TO BE MUCH
STRONGER THAN YDAY/TODAY...WITH 0-6 KM SHEAR OF 45-60 KTS...AND
0-3 KM SRH AROUND 200 IN EC WI. MODELS SUGGEST A NICE LOW-LEVEL
CONVERGENCE/UPPER LEVEL DIVG COUPLET OVER EC WI TOWARD 00Z/SAT...
WITH THE REGION IN THE RRQ OF A 90 KT UPPER LEVEL JET. IF
INSTABILITY DEVELOPS AS EXPECTED...COULD DEFINITELY SEE A TORNADO
THREAT DURING THE LATE AFT/EARLY EVG...ESP IN EC WI. WILL CARRY
LIKELY POPS OVER THE ENTIRE CWA DURING THE EVG...THEN SLGT CHC/
CHC POPS FOR THE OVERNIGHT PERIOD.

PCPN CHANCES ON SATURDAY WILL BE FOCUSED ON DIURNAL CONVECTION...
AND ALONG A COLD FRONTAL BOUNDARY SAGGING SOUTH THROUGH N WI. WILL
CONTINUE TO FOCUS THE HIGHEST POPS OVER N WI DURING THE AFTERNOON.
SHOWER CHANCES WILL CONTINUE SATURDAY NIGHT...WITH THE HIGHEST POPS
OVER NORTHERN WI. PCPN SHOULD TAPER OFF ON SUNDAY MORNING.

CANADIAN HIGH PRESSURE WILL BE IN CONTROL LATE SUNDAY INTO
TUESDAY. LOOKS LIKE A DECENT CHANCE OF SOME FROST OVER NORTH
CENTRAL AND FAR NORTHEAST WI SUNDAY NIGHT AND MONDAY NIGHT...SO
HAVE ADDED PATCHY/AREAS OF FROST TO THE FCST.

PCPN CHANCES WILL RETURN TUESDAY NIGHT INTO THURSDAY AS THE
CANADIAN HIGH SHIFTS TO THE EAST. WILL HOLD OFF ON ANY MENTION OF
THUNDER UNTIL THURSDAY...BASED ON INSTABILITY FCSTS OFF THE ECMWF
MODEL.

.AVIATION...FOR 18Z TAF ISSUANCE
ISSUED AT 1226 PM CDT THU MAY 30 2013

TSTMS HAVE ALREADY BLOSSOMED ACROSS THE MIDWEST/WRN
GREAT LAKES THIS AFTERNOON AS A SHORTWAVE RIDES NE INTO THE REGION
AND INTERACTS WITH AN UNSTABLE ATMOSPHERE AND INCREASING SHEAR.
THESE STORMS MAY BECOME SEVERE WITH DAMAGING WIND GUSTS AND
TORRENTIAL DOWNPOURS THE MAIN THREATS. VFR CONDITIONS IN GENERAL
WL PERSIST THIS AFTERNOON...BUT QUICKLY BECOME MVFR CIGS/VSBYS
UNDER ANY TSTMS. THE THREAT FOR ADDITIONAL SHWRS/TSTMS CONTS TNGT
AS ANOTHER SHORTWAVE APPROACHES. EXPECT MVFR CIGS/VSBYS TNGT WITH
LOCALLY IFR CONDITIONS OVER THE RHI...AUW AND CWA TAF SITES AFTER
06Z. PCPN CHCS PERSIST INTO FRI AS A CDFNT MOVES INTO THE UPR MS
VALLEY MORE SHORTWAVES ARRIVE. VFR CONDITIONS SHOULD RETURN BY
MID-MORNING...WITH MORE MVFR CONDITIONS NEAR ANY TSTMS.

.HYDROLOGY...
ISSUED AT 308 PM CDT THU MAY 30 2013

1 TO 3 INCHES OF RAIN FELL LAST NIGHT ACROSS PORTIONS OF CENTRAL
WISCONSIN WITH MORE PCPN EXPECTED THIS AFTERNOON...TONIGHT AND
FRIDAY. THE GROUND OVER THIS AREA REMAINS SATURATED AND IT WILL NOT
TAKE MUCH MORE WATER TO CAUSE PONDING ON AREA ROADWAYS...AND ALLOW
FOR RIVERS AND STREAMS TO RISE. PEOPLE LIVING NEAR LOW-LYING
AREAS...RIVERS AND STREAMS SHOULD KEEP ALERT FOR HEAVY RAINFALL
AND BE PREPARED TO MOVE TO HIGHER GROUND IF ANY FLOODING IS
OBSERVED.
