EVENT...NARROW CNVTN BAND WITH MOD/HVY RAIN
.
SATELLITE ANALYSIS AND TRENDS...NARROW BAND OF CNVTN BEGAN TO FIRE UP
AFTER 22Z AND NOW EXTENDS FM N MO THRU CENTRAL WI. OBJECTIVE ANALYSIS
SHOWS THAT IT LIES WITHIN ZONE OF SFC CONVERGENCE..WITH MAX CONVERGENCE
AND COLDEST CONVECTIVE CLOUD TOPS FM NR OTM TO DBQ/IA. THIS ALSO
COINCIDES WITH 850MB THETA-E RIDGE..WITH PROFILER DATA SHOWING SWRLY
LL JET OVERLYING THE RIDGE. THE LINE HAS BEEN EDGING EWD PRECLUDING HVY
TOTALS. HYDROESTIMATOR INDICATES HRLY RATES OF 0.5"+..BUT WITH LN MOVG
THE HE IS INDICATING LESSER 1 HR TOTALS OF 0.2-0.4". HOWEVER..RAPIDLY
COOLING TOPS INDICATE INCRG INTENSITY.
.
EVEN THOUGH THE NARROW LN OF CNVTN HAS BEEN EDGING EWD..THE CONCERN IS
THAT THE COVERAGE OF MOD/HVY PRECIP WILL EXPAND. MAIN BAND OF PRECIP
EXTENDS FM TX/SW OK THRU NE KS INTO W HALF OF IA AND COINCIDES WITH 850MB
FRONT. LEADING EDGE IS SPREADING SURGING NEWD ACRS SE MN/WI BORDER ATTM.
.
FURTHER E..WITH THE NARROWER CNVTV BAND..THE CONCERN IS THAT IT WILL
CONTINUE TO INTENSIFY AS LL WAA SURGES ACRS IL INTO S WI AS SFC PLOTS
OVER IL SHOW 60S TEMPS AND 50S DEW POINTS MOVG NWD. WITH SNOW COVER IN
PLACE..MOD/HVY RAIN CAN EXACERBATE MELTING/RUNOFF PROBLEMS. LATEST G12
IMAGE AT 0015Z SUGGEST THE POSSIBILITY OF SOME CELL TRAINING OVER E IA
THRU SRN/CENTRAL WI OVER THE NEXT FEW HRS.
