CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 100 PM EDT SUN JUL 30 2000 CURR SAT LOOP SHWS LRG BREAKS IN SRN ZNS AND SOME CU POPPING ALONG HIER TRRN. RDR RATHER QUIET ALL THINGS CONSIDERED...BUT GIVE IT AN HOUR. THE COLD/DRIER AIR DAM SHOWS SIGNS OF GIVING UP...AS DWPTS VERY HI (>65F) FOR ALL OF CWA. UPR TROF AND SFC SHADOW OV MIDWEST. DIDN/T I WRITE THIS YESTERDAY?? WHEN WILL THIS PTRN BREAK DOWN? THAT IS THE ONLY QUESTION. THE MAIN TASK WUD BE TO TRY TO NARROW THE OCCURRANCE/LIKLIHOOD OF PRECIP. BUT TO DO THAT IN THIS SET-UP WOULD MAKE US ALL UTTERLY MAD. THE BEST CALL IS PROBABLY TO RUN WITH THE GUIDANCE AND PLAY THE POPS MDT (HI CHCS TO LIKLIES) THRU THE PD. AT FIRST GLANCE...THE NGM MOS BULLETINS ALL SEEM VERY PESSIMISTIC W/CLD CVR FCST...BUT IT IS WHAT WE HAVE SEEN FOR DAYS NOW. WHY NOT FALL IN LINE? THE MOST PRECISE I WANT TO BE ATTM IS TO SAY THAT MOST OF THE PRECIP WL BE FALLING DURING DIURNAL PEAK HEATING AND ON TOWARD MIDNIGHT. SCT NATURE OF CONVECTION WL PRECLUDE ME FROM WRITING STATEMENTS TO HEIGHTEN FLOOD POTENTIAL. NO ONE AREA IS ANY MORE PRONE TO FLOODING AT THIS POINT THAN ANY OTHER. BESIDE...WE HV HAD SOME RAIN AND THE STREAMS ARE HANDLING THINGS VERY WELL. XTNDD: SAME OLD SAME OLD...WED LOOKING SLIGHTLY WARMER THAN OTHER DAYS...AND POPS CONSISTENT THROUGHOUT THE PD. UPR TROF LOOKS TO FILL IN THRU THE PD AND MAY AC TUALLY DISAPPEAR AND ONLY BE REFLECTED BY LRG UPR HI OVER ERN ATLTC. NEED THERE BE MORE SAID THAN THIS: CHC SHRA/TSRA EVERY DAY W/NEARLY NORMAL TEMPS? .CTP...NONE. DANGELO
