AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
440 AM CDT WED MAY 7 2014

.TODAY AND TONIGHT...FORECAST CONFIDENCE MEDIUM.

THUNDERSTORMS COMING TO AN END OVER EAST CENTRAL WI. HOWEVER WILL
KEEP CHANCES OF TSTORMS IN THE FORECAST THROUGH THE MORNING AS 850-
700 MB WARM ADVECTION CONTINUES WITH WEAK CAPPING ALOFT. SKEPTICAL
OF WIDESPREAD STRATUS DEVELOPMENT TODAY AS SUGGESTED BY SOME OF THE
MODEL GUIDANCE. ALTHOUGH LOW LEVEL MOISTURE WILL INCREASE...BELIEVE
MODELS HAVE A HIGH BIAS WITH THE MOISTURE. THERE COULD HOWEVER BE
SOME FOG OVER AND NEAR THE LAKE VIA ADVECTION FOG.

THE WARM FRONT WILL MAKE IT TO THE IL AND WI BORDER WITH 70S STILL
FORECAST SOUTH AND WEST OF MADISON ESPECIALLY WITH LOWER CONFIDENCE
IN STRATUS DEVELOPMENT. ELY WINDS WILL KEEP TEMPS COOLER ELSEWHERE
WITH 50S NEAR THE LAKE. THE WARM FRONT WILL THEN SLOWLY MOVE NWD
THROUGH THE CWA TONIGHT. FAIRLY GOOD CAPPING ALOFT BUT WILL HAVE TO
WATCH FOR MCS DEVELOPMENT OVER SRN MN. OTHERWISE ONLY HAVE LOW POPS
IN THE NRN CWA AS 850 MB WARM ADVECTION INCREASES.

.THURSDAY - CONFIDENCE...MEDIUM
SRN WI EXPECTED TO BE WELL ENTRENCHED IN THE WARM SECTOR WITH
SOUTHERLY LOW LEVEL FLOW WELL ESTABLISHED. SURFACE LOW LIFTS FROM
NEBRASKA TO MINNESOTA. STRONGEST DYNAMICS REMAIN TO OUR WEST...
HOWEVER SSW UPPER FLOW STILL SHOWS SOME VORT ACTION...THOUGH STILL
LOOKING HIGHLY CONVECTIVE IN NATURE AND SUSPECT. WIND FIELDS RAMP
UP AS THE DAY WEARS ON. CWASP VALUES OF 75 TO 85 PCT PRIOR TO 00Z.
IF A TRIGGER CAN BE REALIZED DURING PRIME TIME HEATING/INSTABILITY
WITH IN THE WARM SECTOR WE WOULD BE LOOKING AT ALL FORMS OF SEVERE
WEATHER ON THE TABLE...ESP ACROSS WRN 1/2 OF THE CWA. SEEING SOME
HIGH 0-3KM SHEAR NUMBERS FROM BUFKIT. THE HIGHER VALUES OF CWASP
AND IMPRESSIVE NUMBERS ON THE CIPS ANALOGS CERTAINLY WARRANTS
HEIGHTENED CONCERN IF THIS WARM SECTOR CAP CAN BE BROKEN. THE NAM
SOUNDING ERODES THE CAP WITH CONVECTION AFTER 2 PM WHILE THE GFS
HOLDS THE CAP FIRM. THE NAM MAY BE A BIT TOO MOIST. SWODY2 HAS
HATCHED AREA FROM NW WI SSW INTO NE IA...THIS LOOKS REASONABLE FOR
NOW GIVEN PLACEMENT OF UPPER DYNAMICS AND LOW LEVEL JET AXIS. WILL
HAVE HIGHEST POPS IN THE WESTERN CWA CLOSER TO MOIST AXIS AND 700
MILLIBAR SPEED MAX. IF A DRIER AND MORE CAPPED GFS SOLUTION PLAYS
OUT WILL HAVE TO WAIT UNTIL EVENING FOR THE MAIN DYNAMICS AND
FRONT TO ERODE THE CAP. EXPECTING 925 TEMPS TO SUPPORT SOME SOME
LOW 80S IN THE SRN CWA.

.THURSDAY NIGHT - CONFIDENCE...MEDIUM
HIGHEST POPS THIS PERIOD AS SURFACE/850 FRONTS AND ENCROACHING
DYNAMICS ALL IMPINGE UPON SRN WI TO SUPPORT MORE ORGANIZED CONVECTION.
STILL THINK WE WILL HAVE ENOUGH INSTABILITY ESP IN WRN CWA CLOSER
TO 850 JET AXIS AND BETTER DIVERGENCE ALOFT FROM 200-300 MILLIBAR
JET CORE. SEVERE POTENTIAL LOOKS HIGHEST IN THE WESTERN CWA WHERE
THESE FORCING MECHANISMS INTERACT WITH MORE PRIME LEFTOVER DAYTIME
INSTABILITY. CIPS ANALOGS LOOK PRETTY IMPRESSIVE TO SUGGEST SOME
SVR POTENTIAL WITH CONVECTION LIKELY TAKING A LINEAR CONFIGURATION
WITH WIND BEING THE MORE DOMINANT CONCERN.

.FRIDAY - CONFIDENCE...MEDIUM
FRONT AND INSTABILITY SHIFT EAST WITH LINGERING SHRA. UPPER FLOW
STILL SOUTHWEST SO ADDITIONAL SHORTWAVE ACTIVITY STILL LIKELY.
DRIER AND COOLER AIRMASS WORKS IN...BUT 925 TEMPS STILL SHOW TEMPS
WELL INTO THE 60S.

.SATURDAY - CONFIDENCE...MEDIUM
LOOKS QUIET WITH SURFACE/850 HIGH DOMINATING. 925 TEMPS 10-14C SO
STILL 60S CWA WIDE.

.SUNDAY THROUGH TUESDAY - CONFIDENCE...LOW
MODELS STILL AT ODDS ON HOW NEXT SYSTEM WILL PAN OUT. WHILE THE
GFS HAS 2 DISTINCT LOWS AND A MORE PROGRESSIVE SOLUTION...THE
ECMWF IS MORE CONGEALED WITH AN INVERTED TROUGH LOOK THAT IS MUCH
SLOWER AND PRODUCES A LONGER DURATION PRECIP EVENT FOR SRN WI.
WITH SUCH DIFFERENCES STILL IN PLAY WILL GO WITH THE ALLBLEND POPS
AT THIS TIME.

&&

.AVIATION/12Z TAFS/...REMOVED THE LOWER CIGS FOR TODAY AND TNT AS
THE MODELS APPEAR TO HAVE A HIGH BIAS ON THE LOW LEVEL MOISTURE.
STILL EXPECT SOME FEW-SCT STRATUS WITH PERHAPS SMALL AREAS OF CIGS
FROM LATER THIS AM THROUGH TNT. AS THE WINDS GET LIGHTER TNT AND THE
WARM FRONT MOVES THROUGH...AREAS OF MVFR VSBYS WILL ALSO BE POSSIBLE
ESPECIALLY NEAR LAKE MI AS ADVECTION FOG WILL LIKELY BE PRESENT OVER
THE LAKE. OTHERWISE JUST SMALL CHANCES OF SHOWERS AND TSTORMS FOR
TODAY AND TNT WITH THE WARM FRONTAL PASSAGE.

&&

.MARINE...A SMALL CRAFT ADVISORY IS IN EFFECT FOR TODAY. ELY WINDS
HAVE RECENTLY INCREASED OVER THE NEARSHORE WATERS. THE ELY WINDS AND
WAVES WILL BE PRODUCE MARGINAL SMALL CRAFT ADVISORY CONDITIONS FOR
TODAY WITH LESSER WINDS AND WAVES TONIGHT.

&&

.MKX WATCHES/WARNINGS/ADVISORIES...
WI...NONE.
LM...SMALL CRAFT ADVISORY UNTIL 7 PM CDT THIS EVENING FOR LMZ643>646.
