Area forecast discussion, Mar 25, 3:15 AM CDT, 8 hours 21 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DES MOINES IA 315 AM CDT SUN MAR 25 2007 .SHORT TERM /TODAY-TONIGHT/... SFC ANALYSIS SHOWS LOW PRESSURE OVER NORTHERN NE AT 0630Z WITH ATTENDANT WARM FRONT ACROSS NORTHERN IA ALONG MN BORDER. MINI SUPERCELLS FORMED ALONG THE BOUNDARY EARLIER THIS EVE WITH SOME WIND REPORTS THOUGH ACTIVITY DIM AFTER DARK. MAIN THRUST OF DYNAMICS CONTINUES TO WEST WITH POTENT SHORTWAVE ON WATER VAPOR IMAGERY TNT. CONVECTION CONTINUES TO BREAK OUT ALONG LEADING EDGE OF PVA MAX IN NORTH CENTRAL NEBRASKA HEADING TOWARD NW IOWA. AS POTENT SHORTWAVE MOVES OVER SOUTHERN MN AND NORTHERN IA THIS AFTERNOON...AIRMASS BECOMES INCREASINGLY UNSTABLE AROUND 18Z WITH GFS PROGGED MLCAPE TO INCREASE TO 600-800 J/KG OVER THE EASTERN SECTIONS OF THE STATE WHILE CIN REMAINS IN THE 30 TO 45 J/KG RANGE. DRYLINE FORECAST TO ADVECT EAST WITH LESSENING CAPES TOWARD SUNSET. UPPER LVL WINDS KEY TO CONVECTION THIS AFTERNOON AS MECHANICAL FORCING MAXIMIZED OVER FAR NORTHERN IA...SOUTHEAST MN...AND WESTERN WI. H500-H300 LVL JET CORE OVER STATE BY 18-23Z WITH H300 110KT MAX CENTERED IN STATE. FEEL LINE OF CONVECTION SHOULD FIRE FROM NORTHWEST TOWARD FAR NORTH CENTRAL AS DRYLINE BEGINS TO INTERACT WITH LLVL MOISTURE ALREADY IN PLACE...ENHANCED BY UPPER LVL WIND MAXIMA AND INCREASING INSTABILITY TOWARD THE EARLY AFTERNOON. ELEMENTS SHOULD QUICKLY ADVANCE EAST OUT OF CWA WITH MINIMAL IMPACT AFTER 9 PM. WITH WAVE EXITING THE REGION WILL SEE QUIET WEATHER FOR REMAINDER OF NIGHT. .LONG TERM /MONDAY-SATURDAY/... RELATIVELY WARM PATTERN TO REMAIN FOR MUCH OF THE WEEK WITH WEST TO SOUTHWEST FLOW ALOFT. TEMPS WILL REMAIN MUCH ABOVE GUIDANCE AND HAVE INCREASED TEMPS MOST PERIODS SANS DAYS 6-7 TO REFLECT THE PATTERN. MODELS CONTINUE TO HAVE DIFFERENCES IN HANDLING THE OLD MEXICO H500 LOW FOR MONDAY NIGHT THROUGH TUES NIGHT WITH MOISTURE CHANNEL EITHER BEING ADVECTED INTO CENTRAL IA OR SHUNTED EAST. GFS FAVORS FASTER AND MORE WESTERLY FLOW...EURO FAVORS SLOWER NORTHEASTWARD EJECTION WITH MOISTURE ARRIVING LATER ON TUESDAY. HAVE INCREASED POPS LATE MONDAY NIGHT/TUESDAY AS SOME CONSENSUS HERE. GEM MORE ADAMANT ABOUT KEEPING H500 FLOW AND WAVE AWAY FROM AREA INITIALLY. HAVE TRIMMED HIGHS TUES A BIT WITH PRECIP IN MIND...BUT RAISED HIGHS WED IN ADVANCE OF NEXT STRONG SW WAVE AND INCREASING SW SFC FLOW. GEM/GFS IN CLOSER AGREEMENT WITH OVERALL FEATURES OF OPEN WAVE AND STRONG SHORT WAVE ROTATING AROUND THE BASE OF THE LONG WAVE TROUGH. EURO NOW SUGGESTING WAVE COMPLETELY CUT OFF FROM FLOW ...LIFTING MORE NORTH WITH TIME. HAVE CUT BACK POPS WED AND INCREASED FOR WED NIGHT/THURS AS LOW TRACKS NORTH. GFS ONCE AGAIN THE MOST PROGRESSIVE MODEL AND HAVE DOUBTS IT WILL BE THE MODEL OF CHOICE IN A DAY OR TWO. CONCERNS FOR SEVERE WEATHER WILL BE ONGOING FOR MAINLY LATE WEEK AS INCREASING SW FLOW ALOFT ALLOWS FOR DEEP MOISTURE TO RETURN AHEAD OF H500 SHORT WAVE. ATTM CONFIDENCE LOWERING...BUT FEEL THAT BEST POTENTIAL ON THUR AND FRIDAY DEPENDING ON TIMING OF SHORT WAVE ROUNDING TROUGH. HAVE MADE LITTLE CHANGE TO THUR/FRI PERIOD AND TEMPS WILL BE MAIN ISSUE FOR NEXT 24 HOURS THERE. WITH H500 LOW IN THE VCTY... WILL EXPECT SCT CONVECTION TO CONTINUE. COLD AIR FROM CANADA WILL ALSO NEED TO BE WATCHED...THOUGH WITH SOME TREND TOWARD SLOWER SOLNS ...THIS MAY NOT PRESENT ITSELF AS MUCH OF A PROBLEM. && .DMX WATCHES/WARNINGS/ADVISORIES...NONE && REV
