NWS Milwaukee, WI wrote its last area forecast discussion before this severe thunderstorm warning went out at May 11, 3:06 PM CDT, 2 hours 49 minutes earlier.
Area forecast discussion, May 11, 3:06 PM CDT, 2 hours 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 306 PM CDT WED MAY 11 2011 .TONIGHT AND THURSDAY...FORECAST CONFIDENCE MEDIUM. CURRENT CONVECTION ALONG WARM FRONT TO CONTINUE TO SHIFT SLOWLY EAST THROUGH THE REST OF THE AREA THIS AFTERNOON. MORE THUNDERSTORMS ARE EXPECTED TO MOVE NORTHEAST INTO THE AREA INTO EARLY EVENING...WITH SHORTWAVE TROUGH. THROUGH EARLY EVENING...STRONG ELEVATED CAPES OF 2000 TO 4000 J/KG...WITH DECENT DEEP LAYER SHEAR OF 30 TO 35 KNOTS PLUS...WILL CONTINUE TO BRING CHANCES FOR SEVERE STORMS WITH DAMAGING WINDS AND LARGE HAIL. PRECIPITABLE WATER VALUES OF 1.50 INCHES AND SLOW MOVEMENT OF STORMS ALSO BRING A LOCALIZED FLASH FLOODING RISK. ELEVATED CAPES GET REDUCED LATER TONIGHT...AND SHORTWAVE MOVES OUT OF THE AREA...WITH CAP BUILDING IN. THIS SHOULD GRADUALLY REDUCE AREAL COVERAGE OF CONVECTION AS THE NIGHT GOES ON. LOW STRATUS DECK AND FOG ARE AFFECTING AREAS NEAR THE LAKE. WINDS ARE EXPECTED TO SLOWLY TURN SOUTH TONIGHT AND THURSDAY IN THIS AREA. SO...THESE CONDITIONS SHOULD GET PUSHED BACK TO THE LAKE. SOME CONCERN THAT THIS MAY NOT OCCUR DUE TO THE WEAK NATURE OF THE WINDS...AND IF SO THE FOG AND STRATUS WILL REMAIN. WILL HAVE TO WATCH THIS AREA CLOSELY. THUNDERSTORMS ARE EXPECTED TO BECOME MORE NUMEROUS AGAIN ON THURSDAY...AS WEAK SURFACE LOW AND COLD FRONT SLOWLY SHIFT INTO THE REGION. MEAN LAYER CAPES OF 500 TO 1500 J/KG WITH WEAK TO MODEST DEEP LAYER SHEAR OF 15 TO 20 KNOTS ARE EXPECTED. PRECIPITABLE WATER VALUES REMAIN AROUND 1.50 INCHES...AND WITH SLOW MOTIONS LOCALIZED FLASH FLOODING MAY OCCUR. .FRIDAY...FORECAST CONFIDENCE...MEDIUM MODELS ALL HAVE ONE UPPER LOW OVER SOUTHERN MISSOURI/NORTHERN ARKANSAS. WHILE NORTHERN UPPER LOW REACHES THE EASTERN DAKOTAS/MINNESOTA. THIS LEAVES OUR AREA BETWEEN THESE TWO SYSTEMS WITH AN BROAD RATHER WEAK SURFACE TROUGH AXIS FROM THE GREAT LAKES AND ACROSS SOUTHEAST WISCONSIN AND THROUGH ILLINOIS AND MISSOURI. NAM SOUNDINGS SHOWING MINIMAL CAPE LIFTED FROM AROUND 875 MB...ABOUT 80 J/KG...AROUND NOON BEFORE DRYING OUT MORE DURING THE AFTERNOON. NAM QPF IS LESS THAN A TENTH OF AN INCH...AND GIVEN SOUNDINGS NO MORE THAN CHANCE POPS ARE REASONABLE. .SATURDAY AND SUNDAY...FORECAST CONFIDENCE...MEDIUM GFS AND ECMWF STILL HAVE THE FORECAST AREA BETWEEN THE TWO UPPER LOWS...AS THE NORTHERN LOW DROPS TO IOWA AND THE SOUTHERN LOW MOVES EAST ACROSS KENTUCKY OR TENNESSEE. THE SURFACE TROUGH SAGS SOUTH INTO MORE OF A LOW OVER THE OHIO RIVER VALLEY. NAM AND GFS HAVE MORE QPF SATURDAY THAN THE 00Z ECMWF...AND BOTH GFS AND 00Z ECMWF HAVE SOME QPF SUNDAY...THE ECMWF MORE ACROSS SOUTHERN WISCONSIN. .LONG TERM... .MONDAY THROUGH WEDNESDAY FORECAST CONFIDENCE...MEDIUM THE NORTHERN LOW BECOMES THE PRIMARY LOW AND DROPS SOUTHEAST TOWARD KENTUCKY ON MONDAY...WITH THE UPPER TROUGH HANGING BACK INTO WISCONSIN TUESDAY AND POSSIBLY INTO WEDNESDAY. THE FORECAST AREA...ESPECIALLY THE SOUTHEAST MAY STILL BE IN THE PRECIPITATION CHANCES MONDAY...BUT BU TUESDAY THE GFS AND 00Z ECMWF BUILD A SURFACE HIGH ACROSS THE UPPER GREAT LAKES. HOWEVER THE 00Z ECMWF HAS LIGHT QPF RATHER CLOSE...UP TO SOUTHERN LAKE MICHIGAN TUESDAY THAT RETROGRADES BACK INTO SOUTHEAST WISCONSIN TUESDAY NIGHT AND WEDNESDAY. WILL USE THE CONSENSUS FORECAST IN THIS TIME FRAME. EITHER WAY THICKNESS VALUES ARE QUITE COOL...AND WITH ANY CLOUD COVER AND PRECIP...HIGHS WOULD BE RATHER COOL. && .AVIATION... SCATTERED TO NUMEROUS THUNDERSTORMS EXPECTED TO AFFECT TAF SITES THROUGH THE EARLY EVENING HOURS. IFR VISIBILITIES WITH MVFR CEILINGS ARE EXPECTED WITH ANY OF THE STORMS. SOME OF THE STORMS MAY BE SEVERE...AND PRODUCE DAMAGING WINDS TO 50 KNOTS...LARGE HAIL AND HEAVY RAINFALL. IN ADDITION...KMKE...KENW AND KUES WILL SEE LOW STRATUS AND FOG INTO THE EARLY EVENING...WITH ONSHORE WINDS. LIFR CEILINGS AND VISIBILITIES ARE EXPECTED...WITH KUES POSSIBLY GOING UP TO MVFR CONDITIONS AT TIMES. IF WINDS REMAIN ONSHORE TONIGHT INTO THURSDAY...THE LOW STRATUS DECK AND FOG LINGER AT THE EASTERN SITES. IF WINDS REMAIN SOUTH...THE LOW STRATUS DECK AND FOG WILL REMAIN OVER THE LAKE EAST OF THESE SITES. FOR NOW...THINK WINDS WILL TURN SOUTH AND KEEP THESE CONDITIONS OUT OF THE EASTERN SITES TONIGHT INTO THURSDAY. MVFR VISIBILITIES WITH LIGHT FOG SHOULD THEN LINGER TONIGHT...WITH VFR RETURNING THURSDAY. MORE SCATTERED THUNDERSTORMS ARE POSSIBLE THURSDAY AFTERNOON ACROSS TAF SITES. FOR NOW...WILL JUST MENTION VICINITY IN TAFS. && .MARINE...PATCHY DENSE FOG IS EXPECTED OVER THE NEARSHORE WATERS TONIGHT AND THURSDAY...CONTINUING THE TRENDS FROM TODAY. PATCHY DENSE FOG MAY CONTINUE THURSDAY NIGHT INTO FRIDAY...BEFORE FRONT PUSHES THROUGH THE AREA AND WINDS SHIFT NORTHEAST. BRISK NORTHEAST WINDS OVER THE UPCOMING WEEKEND INTO EARLY NEXT WEEK WILL GENERATE HIGH WAVES OVER THE NEARSHORE WATERS.
