NWS Green Bay, WI wrote its last area forecast discussion before the first event at Sep 10, 4:37 AM CST, 1 hour 23 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 537 AM CDT TUE SEP 10 2013 UPDATED AVIATION PORTION FOR 12Z TAF ISSUANCE .SHORT TERM...TODAY...TONIGHT...AND WEDNESDAY ISSUED AT 234 AM CDT TUE SEP 10 2013 TIMING OF CONVECTION AND DETERMINING THE LEVEL OF SEVERITY OF STORMS THE PRIMARY CHALLENGES TODAY INTO WEDNESDAY. PRIMARY LOCATION OF THE CONVECTION WILL BE WITH A SLOWLY SOUTHWARD MOVING FRONTAL BOUNDARY TODAY INTO TONIGHT AND THEN A COLD FRONT DROPPING INTO NORTHERN WISCONSIN WEDNESDAY AFTERNOON. ISOLATED CONVECTION DEVELOPED ACROSS THE FAR NORTH ALONG AND NEAR A WEAK FRONTAL BOUNDARY. THIS BOUNDARY EXTENDED SOUTHWARD INTO SOUTHERN MINNESOTA WHERE ISOLATED CONVECTION WAS NOTED OVER AREA SOUTHWEST OF MSP. A WEAKENING SURFACE LOW TRACKED ACROSS THE NORTH EARLY THIS MORNING WHILE A WARM FRONT LIFTED NORTH OVER NORTHEAST WISCONSIN OVERNIGHT. WILL CONTINUE TO WATCH THE NORTH FOR CONVECTION...BUT THE WARMING MID LEVELS AND CAPPING WERE KEEPING THE CONVECTION ACROSS THE NORTH IN CHECK SO FAR EARLY THIS MORNING. UPSTREAM A SHORT WAVE TROUGH WAS GENERATING CONVECTION OVER THE NORTHERN PLAINS. PROGS TRACK THIS SHORT WAVE OVER THE NORTHERN GREAT LAKES REGION LATER TODAY WHILE ANOTHER SHORT WAVE DROPS SOUTH INTO SOUTHERN CANADA LATE TONIGHT INTO WEDNESDAY. BUFKIT SOUNDINGS TODAY INTO TONIGHT SHOW PLENTY OF CIN AND MARGINAL CAPE TO WORK WITH. BUT WITH A BOUNDARY DROPPING SOUTHWARD AND DEEP MID LEVEL WINDS OVER THE GREAT LAKES REGION...SOME POTENTIAL OF ISOLATED STRONG TO SEVERE STORMS TODAY INTO TONIGHT. DUE TO THE PERSISTENT WESTERLY FLOW ALOFT TODAY INTO TONIGHT...PROGS DROP THIS BOUNDARY INTO CENTRAL WISCONSIN TODAY AND LINGER IT TONIGHT BEFORE DROPPING SOUTH OF THE FORECAST AREA LATE TONIGHT. WITH A BOUNDARY IN THE VICINITY...LATER SHIFTS WILL NEED TO CHECK A MODIFIED SOUNDING FOR A TRUER DEGREE OF INSTABILITY TODAY. CONVECTION MAY LINGER OVERNIGHT ALONG AND NEAR THIS BOUNDARY AS THE RRQ REGION OF THE UPPER JET SLIDES OVER THE NORTH HALF OF THE STATE WITH THE DIGGING UPPER TROUGH. WHILE THE CONVECTION WITH THE INITIAL FRONT WILL SLIDE SOUTH OF THE FORECAST AREA LATE TONIGHT...A SECONDARY FRONT WITH THE FALLING UPPER HEIGHTS OVER THE GREAT LAKES REGION WILL DROP INTO NORTHERN WISCONSIN THROUGH WEDNESDAY. WITH COOLER H7 TEMPS AND INCREASING LAPSE RATES...GOING FORECAST OF A CHANCE OF WEDNESDAY AFTERNOON STORMS OVER NORTHERN WISCONSIN SEEMS REASONABLE. WITH A WARM START THIS MORNING...WILL RUN A NON DIURNAL TEMP TREND TODAY. FOG WILL LINGER ACROSS THE NORTH...ESPECIALLY NORTH OF THE FRONTAL BOUNDARY. .LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY ISSUED AT 234 AM CDT TUE SEP 10 2013 WHILE NOT CONTINUOUS THRU THE EXTENDED PERIOD...THE MAIN FEATURES IN THE LONG-TERM TO CONSIST OF A ROCKIES UPR RDG AND A NE CONUS UPR TROF. THIS PATTERN WOULD PROVIDE A MAINLY NW FLOW ALOFT INTO THE WRN GREAT LAKES LEAVING NE WI VULNERABLE TO COLD FRONTAL PASSAGES AND A TASTE OF EARLY AUTUMN LATE IN THE WEEK. THE MAIN FCST ISSUE IS HOW TO HANDLE THE NEXT DECENT CHC FOR PCPN LATE IN THE FCST CYCLE. MDLS CONT TO SHOW A RATHER STRONG SHORTWAVE TROF TO DIG INTO THE GREAT LAKES REGION WED NGT. WHILE FORCING AT MID-LEVELS IS STRONG AND THERE IS SOME LIFT FROM THE LEFT EXIT REGION OF THE UPR JET... QUESTION FOR PCPN CHCS WL COME DOWN TO AMOUNT OF MOISTURE LEFT BEHIND AFTER THE PREVIOUS FNT MOVED THRU. BASED ON EXPECTED CAA AND N-NW WINDS COMBINED WITH THE FORCING/LIFT...HAVE ADDED A SLGT CHC OF SHWRS TO NRN WI WED NGT. HAVE ALSO ADDED A BIT MORE CLOUDS TO THE FCST WITH PARTLY CLOUDY SKY CONDITIONS. AS A RESULT...HAVE RAISED MIN TEMPS A DEG OR TWO THROUGHOUT THE FCST AREA. THE UPR TROF TO FIRMLY BE ENTRENCHED OVER THE GREAT LAKES ON THU WITH COOL AIR ALOFT (8H TEMPS AROUND +6C) AND A FAST-MOVING SHORTWAVE DIVING SE THRU WI. WORRIED ABOUT INSTABILITY SHWRS POPPING UP THU AFTERNOON WITH THE HELP OF THE MID-LEVEL FORCING FROM THE SHORTWAVE. AS WAS THE CASE WED NGT...AMOUNT OF MOISTURE AVAILABLE WL DETERMINE WHETHER ANY PCPN COULD DEVELOP. ONCE AGAIN...A FEW SHWRS MAY GET GOING...BUT BE ISOLATED IN NATURE. ONE THING FOR SURE IS THAT TEMPS WL BE MUCH COOLER THAN PREVIOUS DAYS WITH TEMPS ONLY A COUPLE OF DEGS ABOVE NORMAL. THE CRUX OF THE THIS UPR TROF IS FCST TO SHIFT EAST TOWARD THE ERN GREAT LAKES THU NGT AND ALLOW FOR AN AREA OF HI PRES TO BEGIN BUILDING E-SE TOWARD WI AFTER MIDNGT. SKIES TO CLEAR THRU THE NGT...BUT BOUNDARY LAYER WINDS IN THE 15 TO 25 KT RANGE MAY PREVENT TEMPS FROM TRULY TANKING. EVEN SO...EXPECT TO SEE MIN TEMPS OVER THE COLDER SPOTS OF NRN WI TO DIP INTO THE UPR 30S WITH PERHAPS A LITTLE PATCHY FROST. THE REST OF THE FCST AREA TO SEE MAINLY LWR TO MID 40S...WITH AROUND 50 DEGS NEAR LAKE MI. THE BROAD AREA OF HI PRES SETTLES OVER THE GREAT LAKES FOR FRI AND WL BRING BOUNTIFUL SUNSHINE AND LIGHT WINDS TO THE AREA. FRI ALSO LOOKS TO BE THE COOLEST DAY OF THE EXTENDED PERIOD WITH MAX TEMPS ONLY IN THE LWR TO MID 60S. QUIET/COOL WEATHER TO PERSIST OVER NE WI THRU SAT AS THE HI PRES SLOWLY TREKS OFF TO THE EAST. MAY NEED TO LWR TEMPS FRI NGT AS WINDS DECOUPLE AND THE AIR MASS ALOFT IS STILL QUITE COOL. WOULD NOT BE SURPRISED TO SEE PARTS OF NRN WI DROP INTO THE UPR 30S ONCE AGAIN WITH MORE PATCHY FROST. WINDS BY SAT ARE PROGGED TO VEER TO THE S-SW AND BEGIN TO USHER IN WARMER AIR WITH MAX TEMPS GENERALLY IN THE 65-70 DEG RANGE. FCST ISSUES ARISE TOWARD THE LATTER HALF OF THE WEEKEND AS THE MDLS INDICATE AN UPR RDG ATTEMPTING TO RE-ESTABLISH ITSELF OVER THE CNTRL CONUS AND UPR TROFFING TAKING PLACE OVER THE NW AND NE CONUS. PROBLEM IS THAT THE MDLS DISAGREE ON THE STRENGTH OF THESE FEATURES WHICH WOULD IMPACT A SYSTEM MOVING ACROSS THE PLAINS/ MIDWEST. THERE WL ALSO BE A CDFNT IN OUR VICINITY...BUT DOUBTFUL WHETHER THIS FNT WOULD BE NORTH OR SOUTH OF THE FCST AREA ON SUNDAY. JUST TOO MUCH UNCERTAINTY TO MAKE ANY SIGNIFICANT CHANGES TO THE FCST AND GENERALLY FOLLOWED THE CONSENSUS SOLUTION WHICH KEEPS A CHC POP IN THE FCST FOR ALL OF NE WI. UNFORTUNATELY...THIS UNCERTAINTY CARRIES OVER TO MON AS THE MIDWEST SYSTEM SLOWLY WORKS TOWARD THE WRN GREAT LAKES. EXACTLY WHERE THIS SYSTEM WL BE LOCATED TO DETERMINE THE EXTENT OF PCPN CHCS FOR NE WI. FOR NOW...MAY HAVE TO ADD AT LEAST A MINIMAL POP AND HOPE TO GET A BETTER HANDLE ON THIS SYSTEM WITH THE NEXT MDL RUN. && .AVIATION...FOR 12Z TAF ISSUANCE ISSUED AT 537 AM CDT TUE SEP 10 2013 IFR/LIFR CIGS/VSBYS EARLY THIS MORNING ACROSS NORTHERN WISCONSIN AND MAINLY NORTH OF A FRONTAL BOUNDARY ACROSS NORTHERN WISCONSIN...AND WILL IMPROVE TO MVFR CIGS LATER THIS MORNING AND AFTERNOON. MAINLY VFR CONDITIONS SOUTH OF THE FRONT WITH PATCHY MVFR VSBYS DUE TO HAZE. MVFR CIGS MAY TEND TO DEVELOP SOUTHWARD TODAY AS THE FRONT DROPS SOUTH. SOUTH SURFACE WINDS AROUND 10 KNOTS WITH NEAR 40 KNOTS WINDS AT 2000 FEET FROM THE WEST TO SOUTHWEST WILL PRODUCE LLWS CONDITIONS EARLY THIS MORNING. ISOLATED SHOWERS AND STORMS EXPECTED TODAY WITH SHOWERS AND STORMS BECOMING SCATTERED OVER CENTRAL AND EAST CENTRAL WISCONSIN THIS EVENING BEFORE ENDING LATE TONIGHT. && .GRB WATCHES/WARNINGS/ADVISORIES...
