AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1055 AM CDT WED MAY 24 2006

.DISCUSSION...
VERY WARM AIR HAS ARRIVED THIS MORNING...WITH WAA FROM THE SOUTHWEST
HELPING TEMPERATURES TO CLIMB 6-7F AN HOUR THIS MORNING...PUTTING US
CLOSE TO 80F BY 10AM.  850MB TEMPS AT 12Z SOUNDING TIME WOULD
NOT SUSTAIN TEMPS TOO MUCH HIGHER...BUT WITH WAA AT THAT LEVEL FROM
THE WEST AND SOUTHWEST...TEMPS COULD CONCEIVABLY GO A COUPLE OF
DEGREES ABOVE FORECAST LOW 80S IF ENOUGH WARM AIR MOVES IN
OVERHEAD...THEN MIXES DOWN.  WILL ISSUE AN UPDATE FOR MORNING
WORDING AND A SLIGHT BUMP TO THE MAX TEMPS.

&&

.PREV DISCUSSION...
MAIN CONCERN THIS FORECAST IS SEVERE THUNDERSTORM CHANCES THIS
AFTERNOON AND EVENING AND OVER SE IL THU AS VIGOROUS CUTOFF UPPER
LEVEL LOW OVER THE DAKOTAS TRACKS INTO WI/NORTHERN IL THU. 00Z
SHORT RANGE MODELS ARE FAIRLY SIMILAR AND NOT TOO DIFFERENT FROM 12Z
RUNS...ASIDE FROM SUSPICIOUS GFS BULLSEYE QPF FIELD OVER SOUTHERN IL
TONIGHT. GUIDANCE HAS BEEN TRENDING WARMER WITH TEMPS NEXT FEW DAYS
ESPECIALLY FOR HIGHS.

SHORT TERM...TODAY THROUGH FRIDAY NIGHT...
MCS OVER IOWA FEEDING OFF STRONG SSW LOW LEVEL JET WITH WIDESPREAD
CONVECTION AND SCATTERED SHOWERS AS FAR EAST AS FAR NW IL NW OF
GALESBURG EARLY THIS MORNING. THICKER CIRRUS CLOUDS OFF MCS AS FAR
EAST AS PEORIA AND SPRINGFIELD WHILE MOSTLY CLEAR SKIES EAST OF
THERE WHERE JUST THIN CIRRUS CLOUDS. 08Z/3 AM SURFACE MAP SHOWS 997
MB LOW PRESSURE OVER NORTHCENTRAL SD WITH AN OCCLUDED FRONT OVER
EASTERN SD/NE INTO CENTRAL KS AND TO A 1007 MB LOW OVER THE OK
PANHANDLE. MOIST DEWPOINTS 55 TO 65 POOLING AHEAD OF THIS BOUNDARY
AND AS PUSHING INTO EASTERN IOWA/MO. MEANWHILE 1022 MB HIGH PRESSURE
OVER SE OH AND WV KEEPING IL DRY SO FAR WITH DEWPOINTS IN THE UPPER
30S TO MID 40S. TEMPS NOT AS COOL AS PAST MORNINGS WITH READINGS
RANGING FROM AROUND 50F NEAR THE WABASH RIVER TO THE MID 60S IN
CLOUDIER AREAS AND BETTER SSE FLOW FROM PEORIA AND SPRINGFIELD WEST.
UPSTAIRS A 564 DM 500 MB CUTOFF LOW WAS OVER THE CENTRAL DAKOTAS.

HIGH PRESSURE TO RETREAT SLOWLY EASTWARD INTO THE MID ATLANTIC
STATES TODAY WHILE MCS WEAKENS AS IT MOVES TOWARD CENTRAL IL THIS
MORNING WITH ITS WEAKENING CONVECTION. ITS MOISTURE ALONG WITH
INCREASING SOUTHERLY BREEZES BETWEEN HIGH PRESSURE TO THE EAST AND
LOW PRESSURE AND FRONTAL BOUNDARY TO THE WEST WILL INCREASING
MOISTURE ACROSS IL TODAY AS DEWPOINTS RISE INTO THE UPPER 50S TO MID
60S DURING THIS AFTERNOON. THIS ALONG WITH DAYTIME HEATING TO
DESTABILIZE THE ATMOSPHERE TO DEVELOP SCATTERED CONVECTION THIS
AFTERNOON. CAPES INCREASE TO 2000 TO 3000 J/KG OVER WESTERN IL THIS
AFTERNOON WHERE BEST CHANCE OF SEVERE HAIL/WIND POSSIBLE INTO THIS
EVENING. EASTERN IL NOT AS UNSTABLE WITH CAPES 1500 J/KG OR LESS
WITH AIR MASS DRIER SO LESS CHANCE OF SEVERE EAST OF I-57. HAVE
LIKELY CHANCES OF CONVECTION WEST OF I-57 THIS AFTERNOON AND ACROSS
AREA THIS EVENING...THE LOWER TO CHANCE POPS OVERNIGHT WITH HIGHEST
CHANCES OVER SE IL AS OCCLUDED FRONT PUSHES EAST ACROSS IL. BUMPED
UP HIGHS INTO THE LOW TO MID 80S AS 850 MB TEMPS ELEVATE TO 17C.

THINK A DRY WEDGE WILL WORK NE INTO CENTRAL/SE IL LATER TONIGHT AND
THU MORNING WHICH MODELS WERE HINTING AT YESTERDAY AND SHOWING AGAIN
WITH TODAY/S RUNS. FAIRLY STRONG SURFACE AND UPPER LEVEL LOW
PRESSURE MOVES ACROSS SOUTHERN WI THU AND TO DEVELOP CONVECTION AND
INCREASE LOW CLOUDS THU AFTERNOON FROM NW TO SE AS LAPSE RATES
STEEPEN. HIGHEST CAPES ARE IN SE IL FROM I-70 SE DURING MIDDAY WITH
2000 TO 3000 J/KG AND LIFTED INDICES OF MINUS 5 TO 8C BY NAM WHICH
MAY BE A LITTLE HIGH IF DEWPOINTS DONT GET INTO THE MID TO UPPER
60S. SPC HAS SLIGHT RISK OF SEVERE STORMS THU AFTERNOON FROM MATTOON
SE. HAVE CHANCE OF CONVECTION THU WITH BEST CHANCES THU AFTERNOON NE
AREAS. NAM...GFS AND NGM ACTUALLY KEEP SE IL DRY THU WITH DRY WEDGE
HOLDING THROUGH THE DAY SO RISK OF SEVERE WX MAY BE MORE ISOLATED
OVER SE IL THU AFTERNOON. WARMED HIGHS A FEW DEGREES THU WITH LOW TO
MID 80S AND WARMEST SE IL WHERE GUIDANCE SIMILAR WITH UPPER 80S AT
LAWRENCEVILLE WHICH COULD HAPPEN IF DRY WEDGE WITH MORE SUNSHINE
CONTINUES INTO THE AFTERNOON. CHANCE OF SHOWERS LINGERS THU EVENING
BEFORE DIMINISHING FROM THE WEST AFTER MIDNIGHT THU NIGHT AS LOW
PRESSURE DRIFTS EAST INTO EASTERN LOWER MI BY DAWN FRI.

FRI STILL LOOKS DRY AS CLOUDS DECREASE FROM WEST TO EAST AS STRONG
UPPER LEVEL RIDGE STARTING TO BUILD BACK INTO IL. HIGHS 80 TO 85
WITH WARMEST READINGS SW AREAS AND STILL RATHER HUMID WITH DEWPOINTS
IN THE LOWER 60S.

LONG TERM...SATURDAY THROUGH WEDNESDAY...
NO CHANGES MADE TO THE EXTENDED FORECAST AS EXTENDED MODELS SIMILAR
AND CONSISTENT IN SHOWING STRONG UPPER LEVEL RIDGE SLATED TO BUILD
ACROSS THE EASTERN U.S. THIS WEEKEND AND EARLY NEXT WEEK AND KEEP IL
ON THE VERY WARM AND DRY SIDE WITH HIGHS IN THE MID TO UPPER 80S.
COULD BE A SLIGHT CHANCE OF AFTERNOON/EARLY EVENING CONVECTION EACH
DAY ESPECIALLY IN EASTERN IL WITH VERY WARM AND HUMID AIR MASS IN
PLACE...BUT CHANCES TOO LOW TO MENTION IN FORECASTS AT THIS POINT.

&&

.ILX WATCHES/WARNINGS/ADVISORIES...
NONE.
