Area forecast discussion, Jul 11, 2:30 PM CDT, 1 hour 53 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 230 PM CDT SUN JUL 11 2004 .DISCUSSION...LATEST SURFACE ANALYSIS HAD COMPLEX AREA OF LOW PRESSURE OVER THE UPPER MIDWEST...ALONG WITH NUMEROUS BOUNDARIES. AIRMASS REMAINS VERY MOIST AND UNSTABLE ACROSS REGION AND WILL CONTINUE TO SUPPORT OCCASIONAL ROUNDS OF SHOWERS/THUNDERSTORMS UNTIL IT IS SCOURED OUT BY MIDWEEK. MAIN CONCERNS IN THE SHORT TERM REMAIN SHOWER/STORM THREAT UNTIL DRIER/COOLER AIR FILTERS IN BY WEDNESDAY. 12Z MODELS IN GOOD OVERALL AGREEMENT AND HAVE NO REAL FAVORITE AT THIS TIME. STILL...WILL CONTINUE TO FOLLOW THE ETA FOR THE DETAILS. GUIDANCE TEMPERATURES CLOSE/REASONABLE AND WILL NOT STRAY TOO FAR. SHORT TERM...TONIGHT THROUGH WEDNESDAY NIGHT... TONIGHT...EXPECT SHOWERS/STORMS TO CONTINUE TO TREK ACROSS FORECAST AREA...ESPECIALLY DURING THE EVENING HOURS. THE CONVECTION WILL BE SUPPORTED BY STRONG DIURNAL INSTABILITY AS WELL AS UPPER FORCING FROM AN APPROACHING SHORTWAVE AND MCV. PRECIPITABLE WATER VALUES APPROACHING TWO INCHES CONTINUE TO SUPPORT A HEAVY RAIN THREAT... THOUGH THE FASTER SPEED OF TONIGHT/S STORMS SHOULD MITIGATE THIS SOMEWHAT. MONDAY AND MONDAY NIGHT...WEAK RIDGING WILL BUILD IN ALOFT BEHIND DEPARTING SHORT WAVE (WHICH SHOULD ALSO PULL MAIN FRONTAL BOUNDARY TO OUR SOUTH). HOWEVER...WILL LINGER A MORNING CHANCE OF CONVECTION IN THE EAST TO CAPTURE ANY REMAINING NOCTURNAL STORMS. OTHERWISE...A WARM AND HUMID AIRMASS WILL BE IN PLACE WITH CONSIDERABLE DIURNAL INSTABILITY EXPECTED. HOWEVER...WILL NOT CARRY PRECIPITATION MENTION AT THIS TIME DUE TO A LACK OF A FOCUSING MECHANISM. THIS WILL NEED TO BE MONITORED BY LATER SHIFTS. TUESDAY AND TUESDAY NIGHT...STRONG UPPER LOW...CURRENTLY OVER SOUTHWEST CANADA...WILL DIVE ACROSS THE GREAT LAKES AND PULL A FRONTAL BOUNDARY THROUGH THE STATE. THE UNSTABLE AIRMASS IN PLACE AND GOOD FORCING WITH THE UPPER WAVE/SURFACE FRONT SUPPORT SHOWERS/STORMS ONCE AGAIN. CURRENT INDICATIONS ARE THAT THE FRONT SHOULD CLEAR MAJORITY OF AREA BY TUESDAY EVENING...TAKING THE PRECIPITATION THREAT WITH IT. WEDNESDAY AND WEDNESDAY NIGHT...FLOW BECOMES NEUTRAL ALOFT AND HIGH PRESSURE BUILDS IN AT THE SURFACE AS THE UNSEASONABLY STRONG UPPER WAVE CARVES OUT A TROF IN THE EASTERN UNITED STATES. THIS WILL RESULT IN DRY CONDITIONS AND SOMEWHAT BELOW NORMAL TEMPERATURES. LONG TERM...THURSDAY THROUGH SUNDAY...MODELS/ENSEMBLES CONTINUE TO BE IN GOOD OVERALL AGREEMENT WITH THE UNSEASONABLY STRONG TROF THAT WILL BE IN PLACE OVER THE EASTERN UNITED STATES FROM MIDWEEK INTO THE WEEKEND. INITIALLY THIS WILL RESULT IN HIGH PRESSURE AT THE SURFACE ACROSS THE REGION...ALONG WITH DRY CONDITIONS AND BELOW NORMAL TEMPERATURES. RETURN FLOW DEVELOPS ON SATURDAY...SIGNALING A RETURN TO MORE SEASONABLE HEAT AND HUMIDITY. A SYSTEM IS EXPECTED TO MOVE OUT OF THE PLAINS ON SUNDAY AND BRING THE REGION ITS NEXT CHANCE FOR SHOWERS/STORMS. && .ILX WATCHES/WARNINGS/ADVISORIES... IL...NONE. && BAK
