AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREEN BAY WI 318 PM CDT TUE OCT 23 2007 .SHORT TERM...TONIGHT AND WEDNESDAY...MAIN CONCERN IS WITH PASSING SHORTWAVE AND SFC COLD FRONT. STRONG SHORT WAVE...AS SEEN ON WV IMAGERY...PRESENTLY MOVING INTO NRN MINNESOTA. THIS WAVE HAS PRODUCED SOME SCATTERED SHOWERS OVER THE ARROWHEAD OF MINNESOTA DURING THE AFTERNOON. DECENT 6.5-7 C/KM MID LEVEL LAPSE RATES OUT AHEAD OF THE SHORTWAVE...WITH THE H850-500 MOISTURE WORKING SE OVER MOST OF THE CWA...PRODUCED THE MID DECK OF CLOUDS ACROSS THE AREA THIS AFTERNOON. THE STRONG SHORTWAVE WILL ROTATE THROUGH THE UPPER NW FLOW THIS EVENING AND EXIT THE AREA AFTER MIDNIGHT. AT THE SFC...COLD FRONT IS CURRENTLY STRETCHING NE TO SW ALONG A CWDV-KDLH-KSTC LINE. FAIRLY LARGE DIFFERENCES BETWEEN THE GFS AND THE REST OF THE MODELS AS THE WAVE PUSHES THROUGH TONIGHT. 12Z GFS DIVES THE SHORTWAVE FARTHER TO THE SOUTHEAST...WHILE THE 12Z NAM/UKMET AND 09Z SREF ARE IN GOOD AGREEMENT THROUGH TONIGHT WITH POSITIONING OF THE WAVE. DIFFERENCES ARE ALSO APPARENT IN THE GFS ENS...WITH THE STD DEV ON H500 HEIGHTS INCREASING OVERNIGHT ACROSS SRN WI. AT THE SFC...THERE SEEMS TO BE FAIRLY GOOD AGREEMENT IN THE TIMING OF THE FRONT...WITH IT PASSING KRHI BY 00Z AND KGRB BETWEEN 03-06Z. HAVE TRENDED TOWARD THE NAM/UKMET/SREF SOLUTION AND HAVE JUST BRUSHED THE PCPN ACROSS THE NRN TIER OF COUNTIES...AS DRIER AIR BETWEEN THE SFC AND H800 ACROSS CENTRAL WI EVAPORATES ANY POSSIBLE PCPN THAT MAY FALL. BEHIND THE FRONT...STRONG NW WINDS LOOK TO PICK UP...AS STRONG CAA BUILDS OVER NRN WI. H925-850 WINDS ARE FROM THE NW AT 30-40 KTS...SHOULD KEEP WINDS UP DURING THE OVERNIGHT HOURS. HAVE SOME CONCERNS ABOUT LAKE EFFECT RAIN/SNOW OVER THE LES REGIONS OF FAR NRN WI. LK SUPERIOR TEMPS AROUND 7-8C OVER WRN PART OF THE LK. GFS COOLER THAN THE NAM...WITH H850 TEMPS AROUND -7C...COMPARED TO -5 ON THE NAM. THIS GIVES A MARGINAL 14C DIFFERENCE BETWEEN THE LK AND H850...BUT WITH PREFERRED NW FLOW ALOFT...BELIEVE THAT ISOLATED LAKE EFFECT RAIN SHOWERS ARE POSSIBLE AFTER MIDNIGHT BEHIND THE TROUGH. THE LIMITING FACTOR WILL BE HOW QUICKLY THE ABOVE H800 DRIER AIR WORKS OVER THE AREA WITH THE BUILDING RIDGE. HAVE LEFT THE MENTION OF MIXING WITH SNOW...AS 1000-500 AND 1000-850 THICKNESSES FALL TO FAVORABLE VALUES...ALTHOUGH BUFKIT SOUNDINGS KEEP SATURATED AREA BELOW BEST SNOW GROWTH REGION. UPPER RIDGE BUILDS OVER THE REGION ON WED BEHIND THE SYSTEM...AS HIGH DEVELOPS OVER THE CNTL PLAINS AND SLIDES NE ACROSS WISCONSIN. HAVE LEFT SOME LINGERING CLOUDS OVER FAR NE WI DURING THE MORNING...DUE TO LINGERING H850-700 MOISTURE AND PROXIMITY TO EXITING TROUGH. OTHERWISE...BELIEVE WED SHOULD BE SUNNY ACROSS THE AREA AS VERY DRY H850-500 AIR MOVES OVER NE WI. WINDS SHOULD DIMINISH DURING THE MORNING HOURS...AS HIGH QUICKLY BUILDS NE OVER THE REGION. TEMPS FOR WED...WENT COOLER THAN TODAY AND CLOSE TO GUIDANCE...AS COLDER AIR DIVES SOUTH BEHIND THE FRONT...BUT WARMER H850 TEMPS WILL APPROACH CNTL WI DURING THE AFTN AS RIDGE BUILDS OVER THE AREA. .LONG TERM...WEDS NGT THROUGH NEXT TUES...MAIN FCST CONCERN IS PCPN CHCS DURING THE THU NGT TO SAT PERIOD. HIGH PRESSURE WILL BRING DRY WX TO THE FCST AREA WEDS NGT INTO THU. MODELS GENERALLY AGREE ON MOVG THE UPPER LOW CURRENTLY OVER ARKANSAS AND LOUISIANA SLOWLY EAST OVER THE NEXT 24 HOURS...THEN RETROGRADING IT NWWD TOWARD THE UPPER MIDWEST/WSTRN OHIO VALLEY REGION LATE IN THE WEEK (DUE TO THE BLOCKING INFLUENCES OF A STG UPPER RIDGE OVER THE WSTRN ATLANTIC OCEAN). AS THIS SYSTEM APPROACHES...SOME LIGHT PCPN SHOULD GRADUALLY SPREAD NORTH ACROSS WI LATE THU NGT INTO FRI. A NORTHERN STREAM TROF IS EXPECTED TO INTERACT WITH THE UPPER LOW FRI NGT INTO SAT...WITH THE SYSTEMS ATTEMPTING TO PHASE JUST TO OUR EAST. THE 12Z/GFS IS QUICKER THAN OTHER MODELS IN SHIFTING THE SYSTEM TO OUR EAST...AND APPEARS TO BE AN OUTLIER. FOR NOW...WILL COUNT ON PCPN LINGERING ACROSS THE FA THROUGH SAT. HIGH PRESSURE WILL BUILD INTO THE RGN DURING THE SUN/MON PERIOD... BRINGING ANOTHER PERIOD OF GENERALLY DRY WX. THERE IS SOME UNCERTAINTY ABOUT THE MON NGT/TUES PERIOD...AS SOME MEDIUM RANGE MODELS BRING LIGHT PCPN INTO THE RGN AS A COLD FRONT APPROACHES AND EVENTUALLY PASSES THROUGH. FOR NOW...WILL JUST LEAVE THE FCST DRY...AS MOST OF THE ENERGY IS EXPECTED TO PASS TO OUR NORTH AND MOISTURE WILL LIKELY BE SPARSE. && .AVIATION...EXPECT VFR CONDITIONS ACROSS NORTHEAST WISCONSIN TONIGHT...AS A COLD FRONT MOVES SOUTHEAST ACROSS THE REGION. MID CLOUDS PRESENTLY OVER MOST OF NE WI PRODUCING BASES AROUND 9-12KFT...BUT EXPECT SOME SCT040 CU TO MOVE ACROSS THE REGION AS FRONT PASSES THROUGH. BEHIND THE FRONT...EXPECT STRONG NW WINDS TO BRING SOME GUSTY CONDITIONS TO THE AREA. WAS TEMPTED TO MENTION LLWS IN THE TAFS BETWEEN 00-09Z...AS STRONG 30-35KT WINDS BETWEEN 2-3KFT MOVE THROUGH BEHIND THE FRONT. DECIDED TO LEAVE LLWS OUT...SINCE STRONG PRESS GRADIENT BEHIND THE FRONT SHOULD KEEP WINDS UP AS BEST CORE OF WINDS PASS OVER. && .MARINE...HAVE DECIDED TO EXTEND THE SCA FOR THE REST OF THE MARINE ZONES FOR THROUGH 18Z TOMORROW. BELIEVE THE STRONGEST WINDS WILL BE OVER THE NEARSHORE AREAS BY DOOR COUNTY AND WILL MENTION WINDS UP TO 30 KTS THERE. 30-35KT H925 WINDS WILL MOVE ACROSS THAT REGION BEHIND THE FRONT AND WITH THE STRONG CAA AND RELATIVELY WARM LK TEMPS...EXPECT MOST OF THE STRENGTH TO MAKE IT TO THE SFC. APPROACHING HIGH ON WED WILL ALLOW WINDS TO DIMINISH DURING THE DAY. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && SRF/TSK
