AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI 319 PM CDT MON JUL 7 2014 .SHORT TERM... TONIGHT...FORECAST CONFIDENCE MEDIUM. MAIN FOCUS WILL BE ON CONVECTIVE TRENDS. DRIER AIR HAS ARRIVED IN THE WAKE OF THE FRONT THAT SHIFTED SOUTHEAST OF WI LATE LAST NIGHT. AXIS OF HIGHER MLCAPE HAS TAKEN SHAPE ACRS PARTS OF NRN WI AHEAD OF A SURFACE TROUGH AND ALSO FROM IA INTO SRN MN WITH BETTER RETURN FLOW THERE. STORMS FIRING FROM NW WI INTO EC MN. THESE ARE TRENDING ESE THOUGH AIRMASS MORE STABLE IN SRN WI. LATEST HRRR SHOWS AXIS OF ONGOING ACTIVITY DROPPING INTO SW WI AS THE EVENING GOES ON WITH STRONGER CELLS STAYING JUST NW OR W OF CWA WITH WEAKER SHOWERS/ISOLD TSRA SPREADING INTO SRN WI. HOWEVER VERY IMPRESSIVE JET PATTERN TAKES SHAPE AS THE EVENING AND OVERNIGHT PROGRESS. 12Z NAM SHOWS A NEARLY COUPLED JET STRUCTURE EVOLVING WITH MASSIVE DIVERGENCE. SO FAVORABLE UPPER JET STREAM WILL CERTAINLY BE A FACTOR. 500 MILLIBAR SHORTWAVE WILL BE APPROACHING WITH DIFFERENTIAL CYCLONIC VORTICITY ADVECTION. THERE WILL BE SOME RECOVERY IN MOISTURE WITH RENEWED 25 TO 35 KNOT SOUTHWEST 850 JET ARRIVING TOWARDS 06Z. BETTER CONVECTIVE POTENTIAL PROGGD TO AFFECT SRN WI IN THE 02-11Z TIME FRAME. GFS SHOWS 0-6 KM SHEAR 50 KNOTS PLUS BY 06Z. SSEO SHOWS BETTER UPDRAFT HELICITY FURTHER WEST THEN DECREASING INTO THE CWA. BUFKIT SOUNDINGS NOT SHOWING A MASSIVE AMOUNT OF CAPE COMING INTO PLAY BUT THERE WILL BE A RETURN FLOW AHEAD OF THIS SYSTEM SO EXPECT THE BEST OVERLAP OF FORCING/THERMODYNAMICS TO BE IN SC WI CLOSER TO SWODY1 AREA OF CONCERN. THE LATEST HRRR IS CERTAINLY A WEAKER SOLUTION THAN THE 12Z NMM AND 12Z ARW. ALL OF THE SHRA/TSRA WILL LIKELY EXIT SE WI AROUND 12Z PLUS OR MINUS AN HOUR. TUESDAY...FORECAST CONFIDENCE MEDIUM. STRONGLY CYCLONIC FLOW WILL PERSIST. SO THIS WILL LIKELY SET UP SOME PRETTY DECENT LAPSE RATES RESULTING IN MORE SHRA/TSRA ACTIVITY. HIGHEST POPS WILL BE PLACED IN THE NE CWA. 925 TEMPS DROP INTO THE TEENS IN THE WAKE OF THIS LATEST FRONT. SO HIGHS WILL DROP BACK INTO THE 70S. TUESDAY NIGHT THROUGH THURSDAY NIGHT...FORECAST CONFIDENCE HIGH. AN UPPER TROUGH WILL SWING ACROSS THE NRN GREAT LAKES FOR TUE NT AND WED AM. THIS MAY ALLOW ISOLD TO SCT INSTABILITY SHOWERS TO CONTINUE FROM TUE AFTERNOON INTO TUE NT OVER EAST CENTRAL WI. THE UPPER TROUGH WILL BE MOVING AWAY FOR WED WITH HEIGHT RISES. THERE WILL REMAIN ENOUGH COLD AIR ALOFT FOR SCT-BKN CUMULUS WITH POSSIBLY SOME SPRINKLES OVER EAST CENTRAL WI. HIGH PRESSURE TO THEN PREVAIL WED NT INTO THU AM. SLY WINDS TO THEN DEVELOP THU AFTERNOON AS SHORTWAVE RIDGING OCCURS AHEAD OF AN APPROACHING SHORTWAVE TROUGH FROM THE NRN PLAINS. TEMPS WILL BE BELOW NORMAL BUT PLEASANT. PWS TO REMAIN BELOW ONE INCH WITH VERY COMFORTABLE HUMIDITY. .LONG TERM...FRIDAY THROUGH MONDAY...FORECAST CONFIDENCE MEDIUM. THERE WILL BE GOOD CHANCES OF SHOWERS AND TSTORMS FRIDAY AFTERNOON AND NIGHT AS A SLOW MOVING SHORTWAVE TROUGH MOVES ESEWD ACROSS THE STATE WITH SLY WINDS AND MOISTURE TRANSPORT AHEAD OF IT. MUCH UNCERTAINTY FOR THE WEEKEND WITH QUASI-ZONAL FLOW AND THE POTENTIAL FOR A W-E STATIONARY FRONT OVER SRN WI OR NEARBY ON SOME OF THE MODELS. THE UNCERTAINTY WILL CONTINUE INTO EARLY NEXT WEEK ON THE DEGREE OF SOUTHWARD DIGGING OF A CANADIAN POLAR TROUGH. WENT WITH CHANCES OF SHOWERS/TSTORMS THROUGH THE WEEKEND AND MONDAY WITH TEMPS AT OR SLIGHTLY BELOW NORMAL. && .AVIATION/00Z TAFS/...VFR INTO THIS EVENING WITH JUST A FEW CU AND SOME INCREASE IN HIGH CLOUDS FROM MN/IA. LOOKING AT A 02-11Z AS THE GENERAL WINDOW FOR STORMS...STARTING IN THE WEST AT 02-04Z AND WRAPPING UP AT THE 11Z TIME IN THE FAR SOUTHEAST. UPPER JET WILL BE A FACTOR SO STORMS EXPECTED TO SURVIVE TO THE EAST DESPITE GETTING INTO THE DIURNALLY LESS FAVORABLE TIMEFRAME. ANY LOWER CIGS AND VSBYS EXPECTED TO BE BRIEF AS STORMS WILL BE MOVING ALONG WITH THE STRONGER FLOW UPSTAIRS. SLIGHT RISK WAS EXPANDED A BIT FURTHER EAST INTO SC WI SO KMSN MORE VULNERABLE TO A SVR STORM THAN THE EASTERN TAF SITES. UPPER FLOW REMAINS CYCLONIC ON TUESDAY SO CHCY POPS FOR SHRA/TSRA. && .MKX WATCHES/WARNINGS/ADVISORIES... WI...NONE. LM...NONE. && TONIGHT/TUESDAY AND AVIATION/MARINE...COLLAR TUESDAY NIGHT THROUGH MONDAY...GEHRING
