Area forecast discussion, Jun 24, 5:30 AM CST, 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DES MOINES IA 630 AM CDT WED JUN 24 2009 .SHORT TERM /TODAY/... NUMEROUS FORECAST PROBLEMS REMAIN IN THE SHORT TERM. LAST EVENINGS MCS HAS WASHED OUT THE VERY OPPRESSIVE NEAR 80 DEGREE DEWPOINTS AND REPLACED THEM WITH VALUES IN THE LOW TO MID 60S. HAVE SOME UNCERTAINTY HOW MUCH THE DEWPOINTS WILL RECOVER TODAY ESPECIALLY WITH ANOTHER OUTFLOW BOUNDARY HEADING EAST OUT OF NEBRASKA. HAVE RAISED DEWPOINTS BACK INTO THE MID 70S THIS AFTERNOON OVER THE SOUTH HOWEVER WITH FORECAST HIGHS IN THE LOWER TO MID 90S...DO NOT EXPECT HEAT INDEX VALUES TO TOP 110 DEGREES AT GOOD QUALITY CONTROLLED REPORTING STATIONS. THEREFORE WILL BE PEELING THE EXCESSIVE HEAT ADVISORY BACK TO THE FAR SOUTHWEST COUNTIES WHERE BETTER CHANCE FOR RECOVERY EXISTS AND REPLACE WITH A HEAT ADVISORY. IN ADDITION...SIGNIFICANT RELIEF OCCURRED OVERNIGHT FURTHER JUSTIFYING THE DOWNGRADE TO ADVISORY. INSTABILITIES ARE BEGINNING TO LIFT BACK TO THE NORTH AS THE MID LEVEL MOISTURE IS BACK IN RECOVERY MODE. MCS HAS BEEN ONGOING OVER EASTERN NEBRASKA MUCH OF THE NIGHT AND HAS BEEN SLOW TO MOVE EASTWARD...FIGHTING STABLE CONDITIONS OVER NORTHERN IOWA. THIS IS EXPECTED TO CHANGE LATER THIS MORNING AND INTO THIS AFTERNOON AS THE MEAN UPPER LEVEL RIDGE FLATTENS WITH SHORT WAVE MOVING ACROSS THE NORTHERN PLAINS AND STRONG KINEMATIC FORCING BEGINS TO KICK IN AIDED BY A NEAR COUPLED JET. EXPECT ANOTHER ROUND OF THUNDERSTORMS...SOME EXPECTED TO BE SEVERE. BETTER 0-6 KM SHEAR WOULD FAVOR A FEW SUPERCELLS WITH RIGHT MOVER STORM MOTIONS TO THE SOUTHEAST. .LONG TERM /TONIGHT THROUGH TUESDAY/... TONIGHT THROUGH TUESDAY CONTINUES TO BE A VERY DIFFICULT FORECAST WITH CHALLENGES OF PROJECTING CONVECTIVE TRENDS AND FAVORED AREAS FOR HEAVY RAIN/SEVERE WEATHER. CURRENTLY...THE NAM/WRF SOLUTIONS LOOK TO HAVE THE BEST HANDLE ON REALITY...ALBEIT A BIT SLOW WITH THE CURRENT CONVECTION MOVING INTO FAR NW IOWA. WORKING UNDER THE ASSUMPTION THAT CONVECTION WILL BE SUSTAINED THROUGH THE DAY...ESPECIALLY ACROSS THE NORTH HALF...THE OUTFLOW WOULD LIKELY REINFORCE A BOUNDARY GENERALLY ACROSS THE WSW PORTION OF THE FORECAST AREA. THIS SCENARIO WOULD LIKELY RESULT IN ANOTHER MCS TONIGHT...FEEDING DOWN THE BOUNDARY AND THE GREATEST INSTABILITY ACROSS THE WEST AND CENTRAL PORTIONS OF THE STATE. CONFIDENCE IN THESE SPECIFICS PLAYING OUT IS STILL QUITE LOW GIVEN THE FAIR TO POOR INITIALIZATION OF THE VARIOUS MODELS. HOWEVER...CURRENT FEELING IS HEAVY RAIN AND ADDITIONAL STRAIGHT LINE WIND THREAT IS STILL LIKELY OVER PORTIONS OF THE FORECAST AREA TONIGHT. HAVE BUMPED POPS UP ANOTHER NOTCH AND ADDED HEAVY RAIN MENTION. IN TERMS OF ANTECEDENT MOISTURE...AREAS SOUTH OF HIGHWAY 30 AND EAST OF INTERSTATE 35...GENERALLY ALL BUT THE NORTHWEST QUADRANT...HAVE THE LOWEST 1-3 HOUR FLASH FLOOD GUIDANCE. HOWEVER...JUST ABOUT ANYWHERE COULD EXPERIENCE FLASH FLOODING IF SUBJECTED TO EXTREME RAINFALL RATES. WILL ALSO HAVE TO MONITOR THE FAST-RESPONDING CREEKS AND RIVERS CLOSELY. ON THURSDAY...THERE COULD BE REMNANTS OF AN OVERNIGHT MCS INITIALLY...AND POSSIBLY REDEVELOPMENT IN THE SOUTHEAST DURING THE AFTERNOON IF THE BOUNDARY STALLS PER THE NAM...BUT BY THEN OUTFLOW MAY HAVE SHOVED THE BOUNDARY TOO FAR SOUTH. IN THE LATER PERIODS...MEDIUM RANGE MODELS STILL FAVOR FRIDAY NIGHT INTO SATURDAY FOR THE NEXT FRONTAL PASSAGE AND HAVE RAISED POPS SLIGHTLY. NO CHANGES TO THE FORECAST FROM SUN-TUES. && .AVIATION...24/12Z SCATTERED THUNDERSTORMS AND OUTFLOW FROM STORMS WILL ONCE AGAIN BE OVER IOWA THROUGH THE PERIOD. EXPECT STORMS TO MOVE OVER NORTHERN IOWA THIS MORNING WITH CONVECTION REACHING CENTRAL IOWA THIS AFTERNOON. ANOTHER COMPLEX OF STORMS IS FORECAST TO MOVE THROUGH THE REGION THIS EVENING. CONDITIONS WILL BE VFR EXCEPT FOR NEAR THUNDERSTORMS. && .DMX WATCHES/WARNINGS/ADVISORIES...
