Edit: NWS forcast discussion

THE LARGE-SCALE PATTERNDOES FAVOR DEVELOPMENT OF A SFC LOW OVER THE MID MS VALLEY AND AMILLER TYPE-B SCENARIO AFTER THAT AS THE UPPER TROUGH SWINGS TOTHE EAST. BUT...THE DEVIL REMAINS IN THE DETAILS. SO...EYES ARECENTERED ON PERHAPS ANOTHER LATE WINTER/EARLY SPRING STORM FOR PAFROM PERHAPS LATE SUNDAY INTO MONDAY NIGHT. MOST MDLS AND ENSEMBLEMEMBERS DO BRING SOME PRECIP INTO AT LEAST SRN HALF OF PA FROMTHIS SYSTEM. HOWEVER...THE BIG TROUBLES REMAIN TIMING...NORTHWARDEXTENT OF PRECIP DUE TO TIMING OF LOW TRANSFER...AND OF COURSETEMPS AND P-TYPES DURING THE PRECIP. IN OTHER WORDS...EVERYTHINGIS STILL UNCERTAIN. DID HAVE ENOUGH CONFIDENCE TO MAKE POPS AROUND50 PCT IN THE S FOR TWO PERIODS...BUT IT IS STILL A DAY 5-6/POTENTIAL/ STORM. PLENTY OF TIME FOR THE PROGS TO WAGGLE ALLDIFFERENT DIRECTIONS FOR MANY DAYS.http://forecast.weather.gov/product.php?site=NWS&issuedby=CTP&product=AFD&format=CI&version=1&glossary=1&highlight=off
