AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1119 AM CST TUE JAN 29 2008

.DISCUSSION...
ISSUED 1004 AM CST TUE JAN 29 2008

CURRENT FORECAST ON TRACK. FRONT CURRENTLY APPROACHING GBG AND
SHOULD SWEEP ACROSS FORECAST AREA DURING THE DAY BRINGING SHARPLY
COLDER TEMPS. SOME SHRA HAVE DEVELOPED DURING LAST HOUR NORTH OF
QUINCY ALONG THE BOUNDARY AND THIS LINE MAY BE THE START OF A MORE
SIGNIFICANT CONVECTIVE EVENT. HOWEVER...LOWS CLOUDS ENTRENCHED
OVER THE EAST AND NORTHEAST ZONES MAY INHIBIT CONVECTION SOMEWHAT
AND LIMIT AND DAMAGING WIND THREAT TO SOUTH OF U.S. HIGHWAY 36.

MAIN THREAT WILL BE WORKING HIGH MOMENTUM AIR DOWNWARD IN
DOWNDRAFTS. SO THIS SITUATION WILL BE A COMBINATION OF GRADIENT
WINDS AND FORCING DUE TO CONVECTION. WILL MONITOR CLOSELY TO
DETERMINE IF A SHORT-FUSED HIGH WIND WARNING MAY BE MORE USEFUL
THAN TRYING TO PINPOINT WHICH SHOWERS MAY PRODUCE DAMAGING GUSTS.
OF COURSE THIS ASSUMES THAT ANY WARNINGS ARE NEEDED WHICH IS STILL
TO BE SEEN.

&&

.AVIATION...
ISSUED 1114 AM CST TUE JAN 29 2008

VSBYS AND CIGS HAVE FALLEN IN WARM ADVECTION AREA IN EASTERN
ILLINOIS AND ARE EVIDENT AT CMI AND BMI. CONDITIONS SHOULD IMPROVE
SOMEWHAT PRIOR TO COLD FRONTAL PASSAGE AS WINDS INCREASE AND
BECOME A BIT MORE SOUTHWESTERLY. HOWEVER...WIND SPEEDS WILL REMAIN
IN THE 20-30KT WITH OCCASIONAL GUSTS TO 35KT RANGE. LINE OF
CONVECTION HAS BEGUN TO FORM UP ALONG STRONG CONVERGENT BOUNDARY
OVER NORTHWEST ILLINOIS. INDIVIDUAL CELLS MAY BE SIGNIFICANT
ENOUGH TO FORCE DOWN HIGH MOMENTUM AIR OFF THE SURFACE.
