EVENT...STNRY CELLS ALONG IL/MO BORDER SHOULD START MOVING SOON
.
SATELLITE ANALYSIS AND TRENDS...COLDEST CLOUD TOPS HAVE CONTRACTED AND
ARE NOW OVER MOSTLY GREENE COUNTY AS WELL AS SE PIKE COUNTY. CELL THAT
WAS MOVING ALONG WITH THE NRN END END OF A BNDRY..NOTICEABLE ON VIS
IMAGERY DUE TO THE THE CU EXTENDING SWD ALONG IT..HAS COLLAPSED. VIS/IR
INDICATE THE OUTFLOW FROM THIS CELL IS CURRENTLY INITIATING A FEW MORE
CELLS JUST SW OF THE COLDEST CLOUD TOPS MENTIONED ABOVE AND THE OUTFLOW
SHOULD BRIEFLY ENHANCE THE CNVTN OVER CALHOUN/GREENE/JERSEY COUNTIES
AND INTO PARTS OF MADISON/MACOUPIN. ONCE THIS BNDRY MOVES THROUGH..IT
SHOULD FINALLY ALLOW THE CELLS TO MOVE AWAY FROM THE MO/IL BORDER TO THE
E. AUTOMATED STLT ESTIMATES SHOWED 2 MAXES OVER W IL OF 2.7-2.9" FOR THE
3 HRS ENDING 1500Z...ONE OVER GREENE COUNTY AND ONE OVER ERN PIKE. BOTH
OF THE MAXES LOOK AS THOUGH THEY SHIFTED SLIGHTLY NE OF WHERE THEY SHOULD
BE DUE TO THE COLDER TOPS BEING BLOWN OFF FROM THE BEST DVLPMT ALONG THE
MO/IL BORDER JUST A BIT. SEE WEB ADDRESS FOR ESTIMATE GRAPHIC. JUST IN
1515Z IMAGE SHOWED A MERGER OF CELLS ALSO ABOUT TO OCCUR OVER STL.
.
HOWEVER//20-30KT 850MB JET CONTINUES TO BE AIMED ACROSS MO INTO W CENTRAL
IL PER RECENT PROFILERS AND GOES SOUNDER/GPS VALUES INDICATES 1.8-1.95"
PW VALUES OVER CENTRAL MO CURRENTLY. DWPTS INTO THE LOW 70S IN CENTRAL
MO ARE ALSO A CONCERN AND LI'S HAVE CERTAINLY BECOME MORE UNSTABLE WITH
THE DIURNAL HEATING THAT HAS OCCURRED THERE. WILL HAVE TO CONTINUE TO
WATCH THAT AREA AS RECENT STLT TRENDS MAY BE HINTING AT DVLPMT ALONG A
KTBN TO KVIH TO KSTL LINE. WILL CONTINUE TO WATCH THIS AREA AND UPDATE
IF NECESSARY.
