Area forecast discussion, Jun 20, 2:10 PM CDT, 6 hours 37 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 210 PM CDT TUE JUN 20 2000 FORECAST CONCERNS MAINLY FIRST 24 HOURS WITH HEAVY RAIN AND SVR WX RISKS 18Z SFC ANALYSIS SHOWING CDFNT ACROSS CENTRAL IOWA. VIS SAT AND RADAR IMAGERY INDICATING A WIDE LINE OF SHOWERS AND THUDNERSTORMS MOVING THROUGH THE CWA ATTM WELL AHEAD OF THE FRONT AND CU ALONG THE FRONT. DIURNAL HEATING HAS ALLOWED FOR A NARROW AXIS OF LIS FROM -4 TO -8 ACROSS CETNRAL AND SE IL WITH DEWPOINTS INTO THE MIDDLE 70S AHEAD OF THIS LINE. THIS IS ALLOWING FOR RAPID INTENSIFICATION ON THE LEADING EDGE OF THE LINE. SPC HAS SLGT RISK GENERALLY ALONG AND WEST OF INTERSTATE 55 AND BEST RISK MAY ACTUALLY BE EAST OF THIS AREA. THE BEST INSTABILITY AND DYNAMICS WILL REMAIN BOTH BOTH NORTH...CLOSER TO THE UPR LVL S/W AND SOUTHWEST OF THE CWA...BUT GIVEN THE ABOVE PARAMETERS WOULD EXPECT THE CURRENT LINE TO CONTINUE TO INTENSIFY...ESPSCIALLY AHEAD OF THE LINE AS WELL AS ON THE SOUTHERN END. A MORE SIGNIFICANT CONCERN IS THE RISK OF FLASH FLOODING ACROSS AREAS IN THE SE STILL DRYING OUT FROM THE PAST WEEKS RAINS. GIVEN FFG OF 1 TO 1.5 INCHES IN A FEW HOURS...PWS OF 1.5 TO 2 INCHES AND THE FACT THAT THE MODELS SHOW THE BOUNDARY SLOWING DOWN BY MORNING ACROSS THIS SAME AREA...WILL ISSUE A FFA FOR ROUGHLY ALONG AND SOUTH OF INTERSTATE 70 FOR TONIGHT. OVERNIGHT SHIFT MAY NEED TO EXTEND BASED OF TRENDS. BETWEEN INTERSTATES 55 AND 70...WILL ADD WORDING OF HEAVY RAINFALL POSSIBLE...BUT WILL LEAVE OUT OF THE WATCH. AS THE FRONT MOVES INTO EASTERN IOWA AND WESTERN IL...ANOTHER LINE OF SHOWERS AND THUDNERSTORMS IS EXPECTED TO DEVELOP. RISK OF SVR WX DOES EXIST WITH CLEARING NOW SHOWING UP AHEAD OF THE FRONT AND DIURNAL HEATING UNDERWAY. WITH THE FRONT STILL TO MOVE THROUGH THE SE DURING THE DAY ON WEDNESDAY...WILL TAPER OFF THE CHCS DURING THE DAY. BEHIND THE FRONT...LOW LVL MSTR RAPIDLY DECREASES AND ALLOWS FOR LESS HUMID...BUT WARMER CONDITIONS WITH MORE SUNSHINE...ESPECIALLY INTO THE AFTERNOON HOURS ACROSS THE WEST AND CENTRAL PARTS OF THE STATE. THIS TREND WILL MOVE INTO THE SE DURING WEDNESDAY EVENING ALLOWING FOR DECREASING CLOUDS THERE. WILL NOT MAKE ANY MAJOR CHANGES TO THE CURRENT ZONES THROUGH THE REMAINDER OF THE PERIOD AS PREV SHIFT HAD A GOOD HANDLE ON THINGS. THE EXTENDED FORECAST INTO THIS WEEKEND PAINTS A POTENTIALLY STORMY PICTURE. MRF SHOWS LOW PRESSURE MOVING OUT OF THE PLAINS AND WEAKENING AS IT MOVES EAST...BUT NOT BEFORE IT HELPS DRAW MOSITURE AND WARMER TEMPS BACK INTO THE REGION ON FRIDAY...WHICH SHOULD BE DRY. THE FRONT APPEARS TO STALL OUT OVER THE WEEKEND ACROSS THE UPPER OHIO VALLEY. THIS...ALONG WITH THE MOISTURE SHOULD PROVIDE AT LEAST CHC OF PCPN FOR SATURDAY AND SUNDAY SO WILL WORD AS SUCH. TEMPS WILL BE IN 80S AND 60S FOR HIGHS/LOWS RESPECTIVELY. THANKS FOR COORDINATION...PAH..IND...LSX PRELIMINARY CCF FOR COORDINATION PURPOSES ONLY...
