LAMBERTWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS State College, PA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 18, 6:57 PM EDT, 1 hour 50 minutes earlier.
Area forecast discussion, Jun 18, 6:57 PM EDT, 1 hour 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 657 PM EDT WED JUN 18 2014 .SYNOPSIS... CENTRAL PA WILL REMAIN ON THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE CENTERED OVER THE SOUTHEAST STATES. A NEARLY STATIONARY FRONTAL BOUNDARY STRETCHED ACROSS THE STATE WILL BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS TONIGHT INTO THURSDAY. SLIGHTLY COOLER AND DRIER AIR IS EXPECTED TO WORK INTO THE AREA THURSDAY AFTERNOON THROUGH FRIDAY AS THE FRONT SAGS SOUTH OF THE STATE. ENOUGH MOISTURE WILL RETURN TO THE REGION THIS WEEKEND TO PRODUCE MAINLY AFTERNOON SCATTERED SHOWERS AND THUNDERSTORMS ONCE AGAIN. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... SFC QUASI SNTRY FRONT EXTENDING FROM NWRN PENN TO THE LEHIGH VALLEY WILL BE THE FOCUS FOR NUMEROUS SHOWERS AND THUNDERSTORMS THIS EVENING THROUGH MUCH OF THE OVERNIGHT HOURS AS AN INITIAL WARM ADVECTION ARM OF CONVECTION /OVER FAR NWRN PENN/ TEAMS UP WITH AN EXTENSIVE MCS /CURRENTLY RACING ACROSS WESTERN LAKE ERIE AND NCENT OHIO/. MESO LOW TRAINING THIS MCS...AND LINKED TO THE RIGHT ENTRANCE REGION OF 80-90 KT JET MAX ACROSS SRN ONTARIO...WILL SLIDE ACROSS LAKE ERIE LATE TONIGHT...AND NWRN PENN THURSDAY MORNING HELPING TO FOCUS THE GREATEST THREAT FOR EXCESSIVE RAIN ACROSS SEVERAL OF OUR NW ZONES THROUGH MID MORNING THURSDAY. RECENTLY ISSUED A FLASH FLOOD WATCH THROUGH 14Z THURSDAY /FOR 4 COUNTIES IN NW PENN/ IN COLLABORATION WITH WFO PBZ. ELSEWHERE ACROSS THE CENTRAL AND WESTERN MTNS OF PENN...THE THREAT EXISTS FOR FEW...TO SEVERAL HOUR PERIOD OF SHOWERS AND PERHAPS A FEW STG TO SVR TSRA WITH THE PASSAGE OF THE SLOWLY WEAKENING MCS LATER TONIGHT. LOWEST PROBABILITY FOR CONVECTION WILL BE ACROSS THE LOWER SUSQ VALLEY AND LIMITED TO VERY LATE TONIGHT. IT WILL BE WARM AND MUGGY OVERNIGHT ACROSS THE SOUTHERN HALF OF THE STATE THANKS TO THICKENING CLOUD COVER FROM THE WEST BY SHORTLY AFTER DUSK. EARLY MORNING MINS WILL BE IN THE UPPER 60S TO AROUND 70 IN SPOTS. ACROSS TO THE NORTHERN TIER...MINS WILL DROP INTO THE MORE COMFORTABLE MID TO UPPER 50S. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/... SHOWERS AND STORMS SHOULD PERSIST THROUGH THE FIRST HALF OF THE MORNING AS SFC FRONT SAGS SOUTHWARD ACROSS NORTHERN PA. SOME AREAS...ESPECIALLY THOSE THROUGH SOUTHERN PA...SHOULD HAVE 0.75 TO 1.5"+ PWATS ALLOWING FOR CONTINUED CONVECTION. LLVL DRY AIR WILL FILTER IN BETWEEN 15 TO 18Z WHICH WILL TAPER OFF ANY PRECIPITATION ALONG THE NORTH...THOUGH WARM AIR AND AN ADVANCING SFC LOW COULD ALLOW CONVECTION TO CONTINUE THROUGH TOMORROW AFTERNOON. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... A BATTLE BETWEEN UPPER LOW OVER EASTERN QUEBEC AND ATTEMPTS BY THE UPPER RIDGE OVER THE SRN U.S. TO REBUILD INTO THE EAST WILL DOMINATE THE LONG TERM PERIOD. MODEL GUIDANCE SUGGESTS THAT THE UPPER LOW WILL WIN OUT EARLY IN THE PERIOD WITH THE UPPER HIGH CENTER RETROGRESSING SWWD TOWARD THE ARKLATEX BY FRIDAY NIGHT. AN AREA OF SFC HIGH PRESSURE WILL KEEP IT A BIT COOLER AND DRIER ON FRIDAY BEHIND A COLD FRONT THAT IS EXPECTED TO MOVE SOUTH OF THE STATE BY THE START OF THE LONG TERM PERIOD. THE UPPER RIDGE IS FORECAST TO BUILD NORTH INTO THE GREAT LAKES WHILE ONE SIGNIFICANT TROF SWINGS EAST OF THE COAST. THIS WILL HELP THE AFOREMENTIONED FRONT TO LIFT BACK NORTH AS A WARM FRONT EARLY IN THE WEEKEND. SEVERAL OTHER SHORTWAVES TRAVELING THROUGH THE UPPER FLOW AROUND THE QUEBEC LOW ARE FORECAST TO PRODUCE A SERIES OF SFC WAVES ALONG THE FRONT. THIS LOOKS TO BRING BACK THE CHANCE OF SHOWERS AND THUNDERSTORMS STARTING EARLY IN THE WEEKEND AND INTO NEXT WEEK. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... VFR CONDS SHOULD CONTINUE THROUGH THE AFTN WITH THE THREAT FOR TSTMS INCREASING THIS EVENING AND INTO THE OVERNIGHT HOURS. THE GLOBAL AND HIRES MODEL DATA TEND TO FAVOR THIS IDEA...SUGGESTING ANOTHER LATE DAY OR NOCTURNAL/OVERNIGHT TSTM EVENT. LOOK FOR CONDITIONS TO DETERIORATE AFTER 00Z THROUGH 12Z...ESPECIALLY FOR THE CENTRAL AND SOUTHERN TAF SITES DUE TO LOW CLOUDS...SCATTERED SHOWERS AND STORMS. MVFR CIGS AND VSBYS IN TSRA SHOULD ADVANCE FROM THE WEST TO EAST...WITH PRECIPITATION AND POSSIBLE IFR CONDITIONS BY MORNING. EXPECT SKIES TO IMPROVE BETWEEN 15 TO 18Z IN THE NORTH AS DRY AIR MOVES IN. OUTLOOK... THU...SCT TSTM IMPACTS LKLY. FRI...NO SIG WX.
