AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 253 PM CDT FRI AUG 28 2009 .SHORT TERM...TONIGHT THROUGH MONDAY NIGHT FORECAST CONCERNS INCLUDE PRECIPITATION CHANCES THROUGH SATURDAY/VERY COOL CONDITIONS SATURDAY THROUGH MONDAY NIGHT. CURRENTLY...WATER VAPOR IMAGERY WAS SHOWING A DEEPENING SHORTWAVE TROUGH DIGGING SOUTHEAST ACROSS MN/WI/IA. NICE CHANNELED DARKENING WAS NOTED ON THE BACKSIDE OF THE TROUGH AS NOSE OF 110-120KT JET WAS MAKING ITS WAY SOUTHEAST OUT OF WESTERN MANITOBA INTO WESTERN MN. AT THE SURFACE...A COLD FRONT EXTENDED FROM WESTERN UPPER MI THROUGH THE TWIN CITIES...INTO EAST CENTRAL SD. RADAR SHOWING A BROKEN/SCATTERED BAND OF SHRA/TS ALONG AND BEHIND THIS FRONTAL BOUNDARY...BEING AIDED BY LEFT EXIT REGION DYNAMICS OF THE 100-120KT JET. OTHERWISE...TEMPERATURES ACROSS THE AREA AHEAD OF THE SHORTWAVE TROUGH/FRONT THIS AFTERNOON WERE AGAIN SLIGHTLY BEHIND SEASONAL NORMALS IN THE 70S. 28.12Z NAM/GFS/ARXWRF AND 28.09Z ALL IN VERY GOOD AGREEMENT THROUGH THE SHORT TERM PERIOD. WILL BE WATCHING THE MID-LEVEL SHORTWAVE CONTINUE DEEPENING OVERHEAD TONIGHT AND SURFACE COLD FRONT PUSHING THROUGH THE AREA THIS EVENING. NAM CONTINUES TO SHOW MODEST MUCAPE AROUND 1000J/KG ALONG THE FRONTAL BOUNDARY INTO THIS EVENING BEING AIDED BY MID-UPPER LEVEL COOLING. WITH THIS IN MIND...WILL GO WITH SCATTERED SHRA/ISOLD T WORDING THROUGH THIS EVENING. MODELS THEN SHOW SHRA/TS THREAT SHIFTING EAST OF THE AREA BY MIDNIGHT...SO DROPPED POPS FOR THE OVERNIGHT HOURS. COLD CYCLONIC FLOW ALOFT ASSOCIATED WITH CLOSED LOW WILL RESIDE OVER THE UPPER MISSISSIPPI RIVER VALLEY/GREAT LAKES REGION THROUGH SATURDAY. STEEP LAPSE RATES WILL GENERATE PLENTIFUL CUMULUS ALONG WITH BREEZY NORTHWEST WINDS. MODELS KEEP COLD CORE SHRA NORTHEAST OF THE AREA...BUT BELIEVE AREAS NORTHEAST OF I-94 CORRIDOR STILL SUSCEPTIBLE TO A FEW -SHRA. WILL KEEP A SLIGHT CHANCE ACROSS THAT AREA FOR NOW. OTHERWISE...WITH CLOUD COVER AND 850MB TEMPERATURES HOVERING BETWEEN 2-5C...HIGHS WILL STRUGGLE INTO THE MID 60S MOST AREAS. SATURDAY NIGHT THROUGH SUNDAY LOOKS DRY WITH SURFACE HIGH BUILDING IN...BUT CONTINUED VERY COOL WITH COLD CYCLONIC FLOW LINGERING OVERHEAD. 850MB TEMPERATURES STILL IN THE 3-5C RANGE...BUT WITH A BIT MORE SUNSHINE...HIGHS ON SUNDAY ARE EXPECTED TO BE A FEW DEGREES WARMER THAN SATURDAY.

CORE OF COLDEST AIR WILL SHIFT EAST OF THE AREA SUNDAY NIGHT...BUT WITH CLEAR SKIES AND SURFACE HIGH SETTLING DIRECTLY OVERHEAD...GOOD RADIATIONAL COOLING EXPECTED. LOWS EXPECTED TO BOTTOM OUT IN THE MID 30S IN THE FAVORED COLD SPOTS ALONG AND NORTHEAST OF THE I-90/94 CORRIDOR...AND IN THE LOWER TO MID 40S ELSEWHERE. EXPECTING PLENTIFUL RIVER VALLEY FOG WITH THIS SYNOPTIC SETUP...BUT WILL ALSO HAVE TO KEEP AN EYE ON FROST POTENTIAL IN THE AFOREMENTIONED FAVORED COLD-SPOT AREAS. THIS WILL DEPEND ON IF FOG FORMS FIRST WITH GREEN/RELATIVELY MOIST VEGETATION AND RELATIVELY MOIST FIRST METER OR TWO ABOVE THE GROUND. THIS WOULD FAVOR MORE OF A FOG POTENTIAL AND THUS INHIBIT THE FROST POTENTIAL. AGAIN...WILL HAVE TO KEEP A CLOSE EYE ON THIS. FOR NOW...HAVE INCLUDED PATCHY FROST MENTION IN THOSE FAVORED COLD-SPOT AREAS. .LONG TERM...TUESDAY THROUGH FRIDAY 28.00Z ECMWF AND 28.06Z GFS REMAIN IN FAIRLY GOOD AGREEMENT WITH OVERALL SYNOPTIC PATTERN THROUGH THE PERIOD. THERE IS EXCELLENT AGREEMENT ON HIGHLY AMPLIFIED PATTERN ACROSS THE CONUS WITH WEST COAST RIDGE/EASTERN CONUS TROUGH WHICH PUTS OUR AREA IN NORTHWEST FLOW ALOFT. LOOKS DRY MONDAY NIGHT THROUGH WEDNESDAY AS STRONG SURFACE HIGH REMAINS ANCHORED ACROSS THE MIDWEST/GREAT LAKES REGION. MINOR DIFFERENCES SHOW UP BETWEEN THE GFS/ECMWF WITH HANDLING OF A MINOR SHORTWAVE TROUGH THAT TOPS/MOVES THROUGH THE MEAN RIDGE TO OUR WEST IN THE WED-FRI TIME FRAME. THE ECMWF TAKES A MORE NORTHERLY TRACK...TAKING THE WAVE THROUGH THE DAKOTAS INTO IA/UPPER MIDWEST WHEREAS THE GFS TAKES IT FROM THE DAKOTAS INTO THE PLAINS...WITH PRECIPITATION REMAINING WELL SOUTHWEST OF OUR AREA. WITH SUCH A STRONG AREA OF HIGH PRESSURE/DRY AIR IN PLACE...CONFINED POPS WEST OF THE MISSISSIPPI RIVER WEDNESDAY NIGHT THROUGH THURSDAY...AND KEPT THURSDAY NIGHT/FRIDAY DRY FOR NOW. WITH AREA STAYING IN NORTHWESTERLY FLOW ALOFT...TEMPERATURES WILL REMAIN A FEW DEGREES BELOW SEASONAL NORMALS. && .AVIATION...

BROAD BAND OF POST-FRONTAL BKN/OVC GENERALLY MVFR CIGS TO MOVE SOUTH ACROSS THE TAF SITES TONIGHT INTO SAT MORNING. WITH DIURNAL WARMING/MIXING AND STEEP LOW LEVEL LAPSE RATES ON SAT...CLOUD DECK SHOULD RISE INTO THE 3K-4K FT RANGE AND BE MORE SCT-BKN FOR SAT AFTERNOON...BECOMING SCT-CLEAR SAT EVENING. && .ARX WATCHES/WARNINGS/ADVISORIES...
