.
SATELLITE ANALYSIS AND TRENDS...STRONG TRAINING CELLS CONTINUE THEIR
MARCH NEWD ACROSS MO TWDS CENTRAL IL ALONG A SFC BNDRY THAT IS JUST
AHEAD OF THE COLD FRNT. THESE CELLS HAVE BEEN VERY EFFICIENT RAINFALL
PRODUCERS THUS FAR WITH AUTOMATED STLT ESTIMATES OF 2-2.5" OVER THE
1700Z-2000Z TIME PERIOD OVER W CENTRAL MO AND EVEN THESE AMOUNTS MAY
BE UNDERDONE DUE TO MERGERS BETWEEN CELLS. LOW/MID LVL WIND FLOW IS
LINED UP FAIRLY UNIFORMLY FROM THE SW ACROSS E OK/NW AR/S MO/W IL PER
PROFILER AND VWP DATA TRANSPORTING PW'S OF 1.2-1.5" NEWD WITHIN THE LINE
OF CELLS. VIS IMAGERY SHOWS SEVERAL OVERSHOOTING TOPS ALONG THE CENTER
OF THE LINE ACROSS SW/S CENTRAL/E CENTRAL MO WITH THE LINE ITSELF SLOWLY
TRANSLATING EWD.
.
HAVE BECOME SLIGHTLY CONCERNED ABOUT THE AREA N OF THE STRONGEST PART
OF THE LINE IN NE MO/E IA AS SFC MOISTURE CNVG HAS STRENGTHENED HERE
OVER THE PAST 2 HRS AND THE CENTER OF THE AXIS OF THETA-E HAS STEADILY
MOVED BACK TO THE NW FROM W CENTRAL IL NOW TO THE NE MO/SE IA BORDER
SINCE 17Z. 20Z SFC ANALYSIS REVEALS THE SFC LOW TO BE BETWEEN KCNC AND
KCSQ IN IA AND HAS BEEN ABLE TO LEECH SOME DEEPER MOISTURE NWD FROM THE
CNVTN TO THE S. JUST OUT AHEAD OF THE COLD FRNT DEWPTS IN THE HIGH 50S
AND LOW 60S NOW STRETCH ACROSS N MO INTO SE IA AND NEARLY TO THE WI/IL
BORDER. A SMALL BREAK IN THE CLOUDS HAD ALLOWED FOR SOME CNVTN TO FIRE
ALONG THE COLD FRNT BUT NOT SURE IF ANYTHING ELSE WILL FORM WITH CIRRUS
AND SUBSIDENCE FROM THE STORMS TO THE S. UPPER LVL DIFFLUENCE IS SEEN
OVER NE MO THOUGH PER STLT WINDS SO THE INGREDIENTS ARE IN PLACE FOR
AT LEAST A FEW HR HVY RAINFALL EVENT IN SE IA/NW IL/NE MO..DEPENDING ON
WHETHER CNVTN INITIATES. SEE WEB ADDRESS FOR GRAPHICS IN ABOUT 10 MIN.
