Area forecast discussion, Jun 20, 2:10 PM CDT, 5 hours 1 minute 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.
