Area forecast discussion, Jul 25, 8:00 PM EDT, 21 minutes before
CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 800 PM EDT TUE JUL 25 1995 TONIGHT/S CONVECTION NEVER SEEMS TO HAVE TAKEN ON THE ORGANIZED APPEARANCE ONE WOULD HAVE EXPECTED LOOKING AT THE MODELS SFC MSTR CONVERGENCE OR UVV PROGS. ACTIVITY OVER THE CTP 33 HAS BEEN NON- SEVERE AND NON-FLOODING ..... LET/S KEEP IT THAT WAY! LOOKING AT RAMSDIS... AREA OF CONCERN SHOULD PROBABLY BE FOCUSED MORE ON ACTIVITY OVER SE OH/WV ATTM...ALTHOUGH THE LAST PICTURE AT 2315Z SHOWS SOME WARMING OF THE COLDEST TOPS IS NOW OCCURRING THERE AS WELL. EXPECT ACTIVITY TO SLOWLY DIE OFF TONIGHT AS THE PCPN CONTINUES TO TREK NORTHEAST. THINK THE SVR POTENTIAL IS JUST ABOUT OVER...JUST WILL HAVE TO WATCH FOR HEAVY RAIN. TOMORROW WILL BE ANOTHER 3H DAY. POTENTIAL FOR ORGANIZED CONVECTION SEEMS LESS TOMORROW... WITH MODELS NOT INDICATING ANY SYNOPTIC SCALE FORCING. STILL...OROGRAPHIC AND MESOSCALE EFFECTS WILL LIKELY ACT TO TRIGGER SOME CVCN. JUST A WAIT AND SEE GAME AS TO WHERE THEY EVENTUALLY POP UP. FOR NOW... CURRENT ZONES LOOK GOOD WITH EVENING RW/TRW ENDING... THEN PARTLY CLOUDY. ANOTHER ROUND OF CHC POPS FOR TOMORROW AFTERNOON LOOKS GOOD AS WELL. PERHAPS WOULD WANT TO ADD THE MENTION OF SOME FOG IN THE OVERNIGHT ZONES...ESP WESTERN PA. JUNG
