Area forecast discussion, Apr 30, 10:50 AM EDT, 4 hours 53 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 1050 AM EDT WED APR 30 2003 HAVE ADJUSTED WINDS TODAY AND WILL NOT CHANGE MUCH ELSE ASIDE FROM A POSSIBLE BUMP IN HIGH TEMPS OVER THE SOUTHWEST. SKY COVER FROM MODEL RH FIELDS WOULD SUGGEST HIGH CLOUDS FOR A GOOD PORTION OF THE DAY AND SOME SC AT DIFFERENT LEVELS DURING THE MORNING AND AFTERNOON. WMFNT CURRENTLY OVER OHIO RIVER IS PROGGED TO MOVE N OF FCST AREA TODAY AND MOST ACTIVITY SHOULD REMAIN ALONG OR N OF THIS FRONT. HOWEVER, A NOTICEABLE VORT ON SATELLITE IMAGERY SEEMS TO BE HANDLED FAIRLY WELL WITH THE MODELS AND THEY INDICATE THAT IT WILL MOVE ENE TOWARDS THE SCIOTO RIVER VALLEY THIS AFTERNOON. SHOWER ACTIVITY SEEMS TO BE OCCURRING UNDERNEATH THE VORT EARLY TODAY THOUGH MOST OF THIS DOESNT APPEAR TO BE REACHING THE GROUND. ADD A LITTLE DAYTIME HEATING AND I THINK THAT ILL BE BUMPING THE POPS OVER SRN FCST AREA TO 50 AND MENTION SCATTERED SHOWERS AND THUNDERSTORMS VS THE CHANCE WORDING WE CURRENTLY HAVE IN THERE. WITH THIS THINKING, WILL NOT BUMP HIGH TEMPS BY THAT MUCH AND LEAVE CURRENT UPPER 70S/AROUND 80 IN ZONES. ISC GRIDDS UPDATED BY TOP OF THE HOUR AND ZONES OUT SHORTLY AFTERWARDS. ILN...NONE. FRANKS
