Severe Thunderstorm Warning 70, NWS State College, PA

CENTRAL PENNSYLVANIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
930 AM EDT WED MAY 24 2000

WHAT A DIFFERENCE A DAY MAKES. (WE/VE BEEN DOWNGRADED TO SLGT RISK
OF SVR BY SPC) BUT...THINGS ARE STILL RIPE FOR SVR DEVELOPMENT...
JUST NOT AS WIDESPREAD AN EVENT IS LIKELY AS THOUGHT B4. THE RAIN
LAST NITE HAS BROUGHT US ABUNDANT LLVL MSTR AND THE SS OUT THE
WINDOW IS HELPING TO RAPIDLY WARM US UP. WEAK TO NON-EXISTENT LLVL
JET WL NOT HELP W/CONTINUED STORM INFLOW POSSIBILITIES. ALSO...SFC
ANALYSIS SHOWS VERY LTL IN THE WAY OF EXISTING BOUNDARIES. WL HV TO
WAIT FOR A TRIGGER TO POP THINGS OFF. REAL FRONT (WHICH IS ALSO VERY
WEAK) SEEMS TO LIE FROM CHI TO STL AT 12Z PER VISB PICS AND HAND
ANALYSIS.

06Z MESOETA SOUNDINGS SEEM TO UNDERESTIMATE THE LLVL MSTR AVBL TODAY
AND THEREFORE NOT QUITE AS IMPRESSIVE AS XPCTD. ALSO THE MDLS KEEP
SFC WINDS ARE MORE W/SW FOR MOST OF THE DAY UNTIL REPONSE TO DIGGING
S/W CROSSING TO OUR NORTH THIS EVENING BRINGS WINDS AROUND TO A MORE
SRLY COMP ACRS ERN ZNS JUST AFT SUNDOWN. OVERALL...ACTION WL BE
LATER IN THE DAY INTO THE EVE AND ON TOWARD MIDNIGHT. HELLACIOUSLY
STRONG NWRLY FLOW JET (120+ KTS) AND OVERALL INSTABILITY WITH DRY
AIR AT MID LVLS KEEP US PRIMED AND...MAYBE...WAITING. WL CONTINUE
THE NEAR-SEVERE WORDS IN THE FCST...AND ADD TO THE ERN ZNS FOR THE
LATE EVENING (ERLY TONIGHT PD).

.CTP...NONE.
