AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
358 AM CDT TUE JUL 8 2008

.DISCUSSION...
CONVECTION ONGOING ACROSS MUCH OF CENTRAL AND SOUTH CENTRAL IOWA AND
MUCAPES OF 1000 TO 2000 J/KG STILL LOOM OVER NORTHERN IOWA IN
ADVANCE OF THE PRIMARY BOUNDARY THAT IS SINKING SLOWLY SOUTH THROUGH
SOUTH DAKOTA AND MINNESOTA. VERY HEAVY RAINFALL FELL OVERNIGHT
ACROSS THE SOUTH WITH MEASURED AMOUNTS IN THE BLOOMFIELD AND
CENTERVILLE AREAS IN THE 6 TO 7 INCH RANGE. IN ADDITION WIDESPREAD 3
TO 5 INCHES FELL OVER PORTIONS OF WARREN..MARION AND MONROE
COUNTIES. NUMEROUS REPORTS OF FLOODING ACROSS THESE AREAS.

THE COLD FRONT WILL MOVE INTO CENTRAL IOWA BY 18Z TODAY. SHOULD SEE
ENOUGH BREAK IN THE CLOUD COVER TO DESTABILIZE ONCE AGAIN FOR
THUNDERSTORMS TO DEVELOP WITH A FEW ONCE AGAIN BECOMING SEVERE.
DESPITE PWATS REMAINING AOA 1.5 INCHES OVER SOUTHERN IOWA THIS
AFTERNOON...STORMS SHOULD BE PROGRESSIVE ENOUGH TO REDUCE THE THREAT
FOR ADDITIONAL HEAVY RAINFALL. POSSIBLE SOME OF TONIGHTS FLOODING
WILL BE REAGGREVATED BUT DO NOT EXPECT RAINFALL THIS AFTERNOON BE
CREATE NEW FLOODING AND THEREFORE WILL NOT BE ISSUING A FLASH FLOOD
WATCH. HIGH PRESSURE MOVES INTO THE STATE TONIGHT.

FAIRLY UNSTABLE AIRMASS WILL REMAIN OVER NORTHERN IOWA WEDNESDAY AND
THURSDAY AND WILL ONLY NEED A SMALL TRIGGER TO FIRE A FEW
THUNDERSTORMS EACH DAY. GIVEN NORTHWEST FLOW ALOFT AND POTENTIAL FOR
SHORTWAVES TO QUICKLY MOVE THROUGH THE FLOW CREATES ENOUGH
UNCERTAINTY TO AT LEAST CARRY LOW POPS OVER THE NORTH. STRONG
WARMING AT AROUND 800 MB THURSDAY WILL ESSENTIALLY CAP OF THE
CENTRAL AND SOUTH AND THE REMAINDER OF THE AREA BY THURSDAY NIGHT.
VERY WARM TEMPERATURES EXPECTED ON FRIDAY WITH THE THERMAL RIDGE
ALOFT AND SOUTHWEST WINDS PROVIDING GOOD MIXING. GUIDANCE BECOMING
MORE PROGRESSIVE WITH COLD FRONTAL ARRIVAL FRIDAY NIGHT AND BEING
SOUTH OF THE AREA BY SATURDAY. HAVE INCREASED POPS IN RESPONSE TO
THIS FRIDAY NIGHT AND DECREASED THEM SATURDAY AND SATURDAY NIGHT.
ALSO HIGH TEMPERATURES OVER THE WEEKEND WILL BE COOLER WITH LESS
HUMID CONDITIONS.

&&

.AVIATION...08/06Z
FRONTAL BOUNDARY WILL REMAIN ACTIVE OVER SOUTHERN IOWA THIS
OVERNIGHT WITH NUMEROUS THUNDERSTORMS CONTINUING THROUGH 09Z THEN
BECOMING SCATTERED. SOME FOG LIKELY THIS MORNING ESPECIALLY IN AREAS
THAT HAD DECENT RAIN AMOUNTS. NEXT FRONTAL BOUNDARY WILL MOVE OUT OF
THE DAKOTAS LATE THIS MORNING OVER NORTHERN IOWA THEN MOVE SOUTH
DURING THE DAY. ADDITIONAL SCT THUNDERSTORMS ARE POSSIBLE DURING THE
AFTERNOON MAINLY NEAR DSM TO OTM. HIGH PRESSURE SETTLES IN DURING
THE EVENING WITH SKIES CLEARING.
