CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
CONVECTIVE TRENDS ARE BEING MONITORED FOR POSSIBILITY OF INCREASING
SEVERE POTENTIAL.
MID-LEVEL JET STREAK/SHORT WAVE TROUGH IS BEGINNING TO TURN
SOUTHEASTWARD FROM SOUTHERN SASKATCHEWAN INTO SOUTHERN MANITOBA.
DOWNSTREAM OF THIS FEATURE...LOW-LEVEL WARM ADVECTION IS BECOMING
MAXIMIZED ACROSS EASTERN WISCONSIN AND THE UPPER PENINSULA OF
MICHIGAN. THIS HAS CONTRIBUTED TO CONVECTIVE DEVELOPMENT DURING
THE PAST 1 TO 2 HOURS WEST/NORTHWEST OF GREEN BAY...WITH ADDITIONAL
ACTIVITY LIKELY DURING THE NEXT FEW HOURS AS FAR NORTH AS PARTS OF
THE WESTERN UPPER PENINSULA OF MICHIGAN. FOCUS FOR DEVELOPMENT
APPEARS TO BE WIND SHIFT FROM SOUTHERLY TO WESTERLY...JUST ABOVE
THE SURFACE...ON NOSE OF LOW-LEVEL THERMAL RIDGE...WHICH IS
CONTRIBUTING TO STEEP LAPSE RATES AND CAPE IN EXCESS OF 2000 J/KG.
WARM ADVECTION STORMS WILL SLOWLY DEVELOP EASTWARD ACROSS THE UPPER
PENINSULA OF MICHIGAN/NORTHEASTERN WISCONSIN/AND NORTHERN LAKE
SUPERIOR...INTO PARTS OF NORTHERN LOWER MICHIGAN BY LATE AFTERNOON.
LARGE HAIL WILL BE PRIMARY SEVERE THREAT WITH THIS ACTIVITY...WITH
SOMEWHAT MORE SIGNIFICANT SUPERCELL THREAT DELAYED UNTIL LATER THIS
AFTENOON IN CLOSER PROXIMITY OT MID-LEVEL JET STREAK...ACROSS THE
MINNESOTA ARROWHEAD/WESTERN LAKE SUPERIOR/WESTERN MICHIGAN UPPER

WEAK SURFACE TROUGH CURVES FROM NORTHEAST MINNESOTA INTO THE MID

DESTABILIZATION...DEEPENING CONVECTIVE DEVELOPMENT IS ONGOING EAST

SLOW INCREASE IN COVERAGE/INTENSITY OF CONVECTIVE ACTIVITY IS

FORCING IN ENTRANCE REGION OF JET STREAK TOPPING BROAD NORTHERN

CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
SEVERE THREAT ACROSS MUCH OF INTERIOR CENTRAL AND SRN FLA WILL
LIKELY INCREASE OVER THE NEXT 1-2 HOURS...AND LAST INTO THE EARLY
EVENING.
LATEST RADAR IMAGERY SHOWS STRONG TO SEVERE CONVECTION ALONG THE
WEST AND EAST COAST SEABREEZE FRONTS...AIDED BY MODERATELY STRONG
DIVERGENCE AHEAD OF UPPER LOW OVER LA. VWP FROM TBW AND MIA
INDICATES THAT MID LEVEL WINDS FROM 30-35 KTS WERE PRESENT OVER
CENTRAL AND SRN FLA. OUTFLOW FROM DEVELOPING CONVECTION ALONG THE
WEST COAST SEA BREEZE FRONT HAS AIDED IN PUSHING THE FRONT FARTHER
INLAND FROM NRN HENDRY CO NWWD INTO SERN HILLSBOROUGH COUNTY.
RECENT RADAR IMAGERY FROM MLB INDICATES THAT THE EAST COAST
SEABREEZE CONTINUES TO ADVANCE INLAND...AND WAS ABOUT 1 KM DEEP. AS
THIS BOUNDARY CONTINUES TO MOVE WWD AND INTERACTS WITH DEVELOPING
CONVECTION ALONG WEST COAST SEA BREEZE FRONT AND NWD MOVING OUTFLOW
BOUNDARY FROM CONVECTION OVER SRN FLA...EXPECT AN INTENSIFICATION
OF CURRENT CONVECTION OVER CENTRAL FLA. ADDITIONAL SEVERE
CONVECTION MAY CONTINUE TO DEVELOP ALONG THE NWWD MOVING OUTFLOW
BOUNDARY ACROSS SCENTRAL INTERIOR FLA. MODERATE INSTABILITY /
AROUND 2500 J/KG OF MUCAPE / ALONG WITH 35-40 KTS OF DEEP LAYER
SHEAR WILL SUPPORT ROTATING UPDRAFTS CAPABLE OF LARGE HAIL. WEAK
SR FLOW IN THE 2-4 KM LAYER WILL LEAD TO MOSTLY OUTFLOW DOMINANT
STORMS. 20 DEGREE TEMPERATURE/DEWPT DEPRESSIONS WOULD FAVOR THE
POTENTIAL FOR DAMAGING DOWNBURST WINDS.

YOUKUM COUNTIES. ADDITIONAL CONVECTION WAS DEVELOPING OVER THE
HIGHER TERRAIN OF THE BIG BEND AREA AND FROM MIDLAND COUNTY SEWD

WILL SUPPORT ROTATING UPDRAFTS WITH THE POTENTIAL FOR LARGE HAIL.
LARGE SUBCLOUD TEMPERATURE/DEWPOINT SPREADS WOULD ALSO FAVOR

CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
THUNDERSTORMS DEVELOPING OVER EXTREME SERN MN / NERN IA / SWRN WI
MAY POSE A SEVERE THREAT OVER THE NEXT 2 TO 3 HOURS...BUT WW NOT
ANTICIPATED ATTM AS STORMS LIKELY WILL WEAKEN SUBSEQUENT TO THE
LOSS OF DAYTIME HEATING.
LATEST SURFACE ANALYSIS SHOWS WEAK SURFACE BOUNDARY LYING ACROSS
NWRN WI / SERN MN / N CENTRAL IA...WITH DEWPOINTS IN THE MID TO
UPPER 60S AHEAD OF BOUNDARY CONTRIBUTING TO AN AXIS OF MODERATE
INSTABILITY FROM SRN WI INTO ERN IA. ALTHOUGH BOUNDARY-LAYER FLOW
IS VEERED ACROSS THE AREA...WNWLY MID-LEVEL FLOW NEAR 50 KTS PER
ARX /LA CROSSE WI/ WSR-88D VWP AND MODEL FORECASTS IS RESULTING IN
SUFFICIENT DEEP-LAYER SHEAR FOR STORM ORGANIZATION / SUPERCELLS.
ALTHOUGH WBZ LEVELS ARE ABOVE 10000 FT AND MID-LEVEL TEMPERATURE
NOT PARTICULARLY COLD PER DVN 18Z RAOB...AMOUNT OF INSTABILITY /
SHEAR SUGGESTS THAT AT LEAST A LIMITED HAIL THREAT EXISTS IN
ADDITION TO LOCALLY DAMAGING WINDS. WITH THE LACK OF A CLEAR
FEATURE ALOFT TO CONTRIBUTING TO BROAD-SCALE UVV...LOSS OF DAYTIME
HEATING SHOULD RESULT IN A SLOW WEAKENING OF THE CONVECTION.

SEVERE THREAT OVER THE NEXT HOUR ACROSS WW 356 WILL BE CONFINED TO
ISOLATED SUPERCELL THUNDERSTORM WHICH WILL MOVE SWD THROUGH STARR
COUNTY. LARGE HAIL AND DAMAGING WINDS WILL BE LIKELY WITH THIS
STORM...BUT THIS STORM HAS SHOWN SIGNS OF BECOMING OUTFLOW DOMINANT

BE POSSIBLE ALONG THE LEADING EDGE OF CONVECTIVE OUTFLOW ACROSS
DUVAL AND WEBB COUNTIES SEEN ON VIS SATELLITE IMAGERY.
OTHERWISE...THE NERN HALF OF WW 356 MAY BE CLEARED IN THE NEXT

GREATEST TORNADO THREAT APPEARS TO EXIST ACROSS THE ERN 1/3 OF WW

ALTHOUGH THUNDERSTORM DEVELOPMENT HAS BEEN MINIMAL ACROSS THE MN

EXPECTED TO DIMINISH AS CONVECTION MOVES EWD OFF THE HIGHER TERRAIN

STRONG TO SEVERE CONVECTION THAT DEVELOPED OVER THE LAST HOUR
