Area forecast discussion, Oct 23, 2:10 PM CST, 2 hours 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LA CROSSE WI 310 PM CDT SUN OCT 23 2011 .SHORT TERM...THROUGH TUESDAY NIGHT 310 PM CDT SUN OCT 23 2011 MAIN FORECAST CONCERN IS WITH THE RAIN CHANCES MONDAY NIGHT INTO TUESDAY NIGHT. SURFACE ANALYSIS THIS AFTERNOON SHOWS AN AREA OF LOW PRESSURE OVER WESTERN ONTARIO WITH A TROUGH OF LOW PRESSURE/WIND SHIFT LINE STRETCHING TO THE SOUTH THROUGH WESTERN WISCONSIN INTO WESTERN IOWA. WATER VAPOR SATELLITE SHOWING A RATHER POTENT SHORT WAVE TROUGH MOVING ACROSS NORTHERN MINNESOTA. THE FORCING FROM THIS WAVE IS RESPONSIBLE FOR THE LINE OF SHOWERS AND ISOLATED THUNDERSTORMS ALONG THE WIND SHIFT LINE FROM EASTERN MINNESOTA INTO NORTHEAST IOWA. THE WAVE WILL CONTINUE TO MOVE EAST THROUGH THE EVENING AND IS EXPECTED TO REACH LOWER MICHIGAN BY 06Z. THE WIND SHIFT LINE IS EXPECTED TO MOVE EAST AT ABOUT THE SAME SPEED. WITH THIS MOVEMENT...THE LINGERING SHOWERS ALONG THE WIND SHIFT LINE ARE EXPECTED TO BE LIMITED TO THE EASTERN PARTS OF THE FORECAST AREA AND WILL CARRY SCATTERED SHOWERS FOR AREAS ALONG AND EAST OF THE MISSISSIPPI RIVER. DID CARRY THESE THROUGH 06Z BUT WOULD NOT BE SURPRISED IF THESE CLEAR OUT OF THE FORECAST BETWEEN 02 AND 04Z. ONCE THIS SYSTEM GOES BY...RIDGE ALOFT WILL BUILD OVER THE AREA FOR MONDAY BEFORE FLATTENING OUT AS THE NEXT SHORT WAVE TROUGH COMES IN. THIS WAVE WILL BE IN THE NORTHERN PART OF A POSITIVE TILT LONG WAVE TROUGH. AS THE WAVE COMES IN...IT IS EXPECTED TO PRODUCE AROUND 4 PVU/S OF VORTICITY ADVECTION IN THE 500-300 MB LAYER. AN AREA OF SURFACE LOW PRESSURE SHOULD DEVELOP OVER NEBRASKA MONDAY NIGHT WITH A WARM FRONT STRETCHING EAST INTO SOUTHERN WISCONSIN. AS THE WAVE MOVES EAST...THE SURFACE LOW IS EXPECTED TO TRACK EAST ALONG THE WARM FRONT REACHING SOUTHERN WISCONSIN LATE TUESDAY AFTERNOON. A WEST TO EAST BAND OF MODERATE FRONTOGENESIS IN THE 1000-500 MB LAYER IS EXPECTED TO DEVELOP NORTH OF WARM FRONT ACROSS SOUTHERN MINNESOTA INTO CENTRAL WISCONSIN. THE LIFT FROM THE FRONTOGENESIS WILL COINCIDE WITH BEST ISENTROPIC UP GLIDE WITH 23.12Z NAM SHOWING UP TO 10 UBAR/S ON THE 295K SURFACE. DESPITE RELATIVELY WEAK FORCING FROM THE SHORT WAVE TROUGH ITSELF...THE LOW LEVEL THERMODYNAMICS ARE EXPECTED TO BE STRONG ENOUGH TO PRODUCE A BAND OF LIGHT TO MODERATE RAIN NORTH OF THE WARM FRONT. THIS RAIN SHOULD START TO MOVE IN/DEVELOP OVER THE AREA AFTER 06Z TUESDAY AND WILL CARRY 50 PERCENT CHANCES OVER THE NORTHEAST PORTIONS OF THE FORECAST AREA. WITH THE BEST FRONTOGENESIS AND ISENTROPIC UP GLIDE EXPECTED TUESDAY MORNING...WILL HAVE 60 TO 70 PERCENT CHANCES ALONG AND NORTHEAST OF I94 AND THEN DROPPING DOWN TO A MAXIMUM OF 60 PERCENT TUESDAY AFTERNOON AS THE FORCING STARTS TO SHIFT EAST. ANY LINGERING RAIN TUESDAY EVENING SHOULD BE LIMITED TO THE EASTERN SECTIONS AND WILL JUST CARRY A 20 TO 40 PERCENT CHANCE THROUGH 06Z WEDNESDAY. .LONG TERM...WEDNESDAY THROUGH SUNDAY 310 PM CDT SUN OCT 23 2011 ONCE THIS SYSTEM MOVES BY...THE MODELS SUGGEST ANOTHER WAVE OF LOW PRESSURE WILL MOVE ALONG THE BAROCLINIC ZONE IN ASSOCIATION WITH THE NEXT SURFACE LOW. BY THIS TIME...THE BAROCLINIC ZONE IS EXPECTED TO BE DOWN IN THE OHIO RIVER VALLEY SO THE SURFACE LOW WILL TRACK WELL TO THE SOUTH OF THE AREA. THE RAIN ON THE NORTH SIDE OF THIS LOW MAY GET CLOSE TO THE SOUTHERN SECTIONS OF THE FORECAST AREA BUT DID STAY WITH A DRY FORECAST FOR WEDNESDAY. ALL THE MODELS THEN SHOW A TROUGH OF LOW PRESSURE COMING THROUGH FRIDAY. THE 23.12Z GFS AND GEM KEEP ANY PRECIPITATION WELL TO THE NORTH ACROSS CANADA WHILE THE 23.12Z ECMWF DOES SHOW SOME ACROSS NORTHERN MINNESOTA AND WISCONSIN. THIS IS A NORTHWARD SHIFT FROM THE 23.00Z RUN AND WILL JUST HAVE A SMALL CHANCE ACROSS THE NORTH. AFTER THAT...NEXT WEEKEND LOOKS DRY AT THIS TIME. && .AVIATION...TODAY AND TONIGHT 1234 PM CDT SUN OCT 23 2011 A COLD FRONT COMBINED WITH AN UPPER LEVEL DISTURBANCE MOVING SOUTHEAST ACROSS THE AREA THIS AFTERNOON WILL PRODUCE SCATTERED SHOWERS AND ISOLATED THUNDER. THERE ARE SOME INDICATIONS THAT A FEW OF THESE STORMS COULD BE STRONG ENOUGH TO PRODUCE SOME SMALL HAIL ALONG WITH GUSTY WINDS...BUT ARE EXPECTED TO REMAIN BELOW SEVERE LIMITS. FELT CONFIDENT ENOUGH TO INCLUDE TEMPO SHRA GROUP IN THE KRST/KLSE TAFS THROUGH 22Z THIS AFTERNOON. HOWEVER...DUE TO THE ANTICIPATED ISOLATED/WIDELY SCATTERED NATURE OF THE THUNDERSTORMS... OPTED JUST TO CARRY A CB REMARK FOR NOW IN THE TAFS. LOOK FOR THIS COLD FRONT TO EXIT EAST OF THE AREA THIS EVENING AROUND 00Z WITH CLOUDS SCATTERING OUT FROM WEST TO EAST. WAS INITIALLY CONCERNED ABOUT RIVER VALLEY FOG AT THE KLSE TAF EARLY MONDAY MORNING AS WINDS DECOUPLE AND A RELATIVELY MOIST GROUND IS EXPECTED FROM TODAY/S RAINFALL...BUT RUC/NAM BUFKIT SOUNDINGS SHOW WINDS AT BLUFF-TOP REMAINING ABOVE 10KT WHICH WOULD ACT TO PRODUCE SOME RIVER CHANNEL STRATUS INSTEAD OF FOG. HAVE THEREFORE INCLUDED SCT003 IN THE KLSE TAF FROM 24.08Z THROUGH 24.14Z. WILL CONTINUE TO WATCH THIS CLOSELY. MORE RAINFALL WOULD INCREASE THE GROUND MOISTURE AND FUEL FOR MORE FOG...STRATUS DEVELOPMENT. OTHERWISE...VFR CONDITIONS ARE IN THE TAFS THROUGH THE PERIOD. && .ARX WATCHES/WARNINGS/ADVISORIES... 310 PM CDT SUN OCT 23 2011 WI...NONE. MN...NONE. IA...NONE. && SHORT TERM...04 LONG TERM...04 AVIATION...DAS
