NWS St. Louis, MO wrote its last area forecast discussion before the first event at Apr 26, 2:50 AM CST, 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 350 AM CDT THU APR 26 2001 MAIN FCST QUESTION THIS MORNING DEALS WITH PRECIP CHANCES FRI INTO SATURDAY. SYNOPTIC SITUATION DOES NOT LOOK TOO FAVORABLE FOR ANYTHING SIGNIFICANT...BUT MODEL QPFS HAVE BEEN AND CONTINUE SHOWING SOME ACCUMULATION AROUND OUR CWFA. AT THE SURFACE...MODELS HAVE A COLD FRONT SLIDING SOUTH THROUGH THE AREA FRIDAY AND REALIGNING AS A NW-SE ORIENTED WARM FRONT FRIDAY NIGHT. ACCORDING TO THE NGM...SOME PORTION OF OUR AREA WILL SEE RAIN ALL DAY FRIDAY. IN CONTRAST...THE AVN AND ETA STAY DRY UNTIL FRIDAY NIGHT (BEYOND THE 48H RANGE OF THE NGM). DIFFERENCE OF OPINION SEEMS TO REST IN PART ON WHEN AND IF THE LOW LEVEL CONVERGENCE ALONG THE FRONTAL FEATURES WILL BE FAVORABLE FOR PRECIP DEVELOPMENT. AS EXPECTED FROM QPF PROGS...THE NGM HAS THE BEST CONVERGENCE DURING THE DAY FRIDAY...WHILE THE ETA AND ESPECIALLY THE AVN...SET THINGS UP FOR FRIDAY NIGHT. A LOOK AT THE ETA 300K SFC...WHICH FALLS BETWEEN 850 AND 700 MB...ALSO SHOWS THE BEST ISENTROPIC PRESSURE ADVECTION ALONG THE WARM FRONT FRIDAY NIGHT. AM LEANING TOWARD THE AVN/ETA SOLN AND PLAN TO KEEP FRIDAY DRY DURING THE DAY. BASED ON THE POSITION OF THE WARM FRONT RELATIVE TO THE FEATURES MENTIONED ABOVE...THE ETA QPF SOLN LOOKS BEST FOR FRIDAY NIGHT. WITH MOST OF THE ETA ACTIVITY STAYING TO THE NORTH AND WEST...THIS WOULD ALSO MEAN KEEPIuNG A DRY FCST. NO CHANGES ARE PLANNED FOR EXTENDED. .STL...NONE LENNING
