FORECASTER: LA CORTEWhat 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 May 28, 7:30 PM EDT, 1 hour 44 minutes earlier.
Area forecast discussion, May 28, 7:30 PM EDT, 1 hour 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 730 PM EDT TUE MAY 28 2013 .SYNOPSIS... A WARM FRONT EXTENDING FROM WESTERN NEW YORK..TO THE SUSQUEHANNA VALLEY...WILL CONTINUE TO DRIFT TO THE NORTHEAST TONIGHT. WARMER AND MORE HUMID CONDITIONS WILL FOLLOW FOR WEDNESDAY... AND LAST INTO THE WEEKEND. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... LATEST REGIONAL RADAR MOSAIC SHOWS PRECIPITATION-FREE CONDITIONS ACROSS MUCH OF THE REGION...AND CLEARING SKIES ACROSS THE SWRN HALF OF THE CWA AS THE WARM FRONT LIFTS NORTH AND EAST. OVERCAST AND COOL CONDITIONS WERE STILL FOUND ACROSS THE SUSQ VALLEY AND POINTS EAST WHERE TEMPS WERE IN THE U50S TO LOWER 60S. THE MAIN AREA OF CONCERN THIS EVENING WILL BE ASSOCIATED WITH THE RATHER LARGE AREA OF THUNDERSTORMS CHUGGING EAST ACROSS LAKE ERIE AND INTO FAR NWRN PENN NEAR THE NOSE OF A 35KT SWRLY LLJ. THE BULK OF THIS FORCING/INSTABILITY WILL LIFT NE ACROSS WRN NEW AND TWD THE FINGER LAKES REGION OVERNIGHT...WITH ML CAPES WANING TO JUST 300-600 J/KG IN MOST AREAS OF CENTRAL PA. HIGH POPS FOR SHRA/POSSIBLE STRONG TO SVR TSRA WILL BE CONFINED TO OUR NW MTN ZONES FOR THE NEXT SEVERAL HOURS...WHILE THE CENTRAL AND SE ZONES SHOULD SEE JUST ISOLATED TO SCT SHOWERS. UNDER THE INCREASING WARM PUSH...THE OVERNIGHT LOWS WILL BE QUITE MILD FOR LATE MAY...AROUND 10 DEG ABOVE NORMAL ON AVERAGE. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/... THE WARM FRONT SHOULD SURGE UP INTO NY ON WED...LEAVING ALL OF MY FCST AREA IN A VERY WARM AND RATHER HUMID AIRMASS. AS SUCH THE BEST FORCING SHOULD SIMILARLY BE SHOVED UP INTO NY STATE. THE MAIN ISSUE WILL BE HOW MUCH IF ANY DIURNAL CONVECTION MANAGES TO KICK OFF DURING THE DAY. THE OPERATIONAL NAM AND 09Z SREF BOTH ARE PRETTY GENEROUS SPLASHING MAINLY LIGHT QPF AROUND IN THE AFTERNOON...WHILE OTHER GUIDANCE IS NOT SO OPTIMISTIC THAT IT WILL RAIN. THE NAM SEEMS TO BE USING A FAIRLY PRONOUNCED SHORT WAVE RIDING OVER THE TOP OF THE BUILDING EASTERN RIDGE TO TRIGGER STORMS WHILE THE OTHER MODELS DO NOT SEEM SO KEEN ON THIS FEATURE. I LIKE THE IDEA OF KEEPING VERY LOW POPS OVER THE FAR NORTH...NEAREST THE WARM FRONT...WITH MOST OF THE REMAINDER OF MY REGION BEING HOT AND HUMID...BUT OTHERWISE RAIN FREE. HIGHS SHOULD SURGE WELL UP INTO THE 80S ACROSS THE AREA...SOME 10-15 DEG ABOVE NORMAL FOR A CHANGE. && .LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/... UPPER RIDGE IS FORECAST TO BUILD/AMPLIFY NWD ALONG THE EASTERN SEABOARD DURING THE PERIOD AS AN UPPER TROF CLOSES OFF/MOVES EASTWARD ACROSS THE NORTHERN PLAINS AND INTO THE WRN GREAT LAKES. THIS WILL BRING ANOTHER WARM SPELL FOR MUCH OF THE EAST AS WE HEAD INTO THE BEGINNING OF JUNE. THE LONG TERM PERIOD WILL BEGIN WITH SEVERAL DAYS OF MAINLY DRY WEATHER WITH LITTLE IN THE WAY OF LARGE SCALE FORCING APPARENT. SRLY/SWRLY SFC WINDS WILL LEAD TO INCREASING SFC MOISTURE AND INSTABILITY...BUT SIGNIFICANT CHANCES FOR SHOWERS/TSTMS WILL HOLD OFF TIL LATER SATURDAY AND ESPECIALLY SUNDAY AND MONDAY WHEN A FRONT MOVES THROUGH THE UPPER FLOW AND INTO PA. A COOL DOWN FOR THE FIRST FULL WEEK OF JUNE MAY THEN BE IN THE OFFING FOR THE NORTHEAST...AS UPPER FLOW BECOMES QUITE TROFFY LOOKING IN SEVERAL OF THE LONG RANGE MODELS. && .AVIATION /00Z WEDNESDAY THROUGH SUNDAY/... STEADY RAIN HAS GIVEN WAY TO SCATTERED SHOWERS OVER MOST OF THE AREA. SWRN TERMINALS HAVE IMPROVED TO VFR WHILE THE SLOW MOVING WARM FRONTAL ZONE CONTINUES TO CAUSE LOW CEILINGS TO HANG TOUGH FROM BFD-UNV DOWN INTO THE LOWER SUSQ VALLEY. IT NOW LOOKS LIKE IMPROVEMENT MAY BE SLOW OVER ABOUT THE NERN HALF OF THE FCST AREA...WHILE SWRN AREAS ARE MORE IN THE WARM AIR AND TRENDING TOWARD VFR WITH JUST SCATTERED SHOWERS AND THUNDERSTORMS. BY MID TO LATE MORNING ALL SITES SHOULD ENJOY THE IMPROVEMENT AS THE WARM FRONT FINALLY EMERGES UP INTO NY STATE. BEST CHANCE FOR MORE THUNDER AND REDUCED CONDITIONS WILL BE ALONG THE NY BORDER WED AFTERNOON. .OUTLOOK... THU-FRI...MAINLY VFR. SOME RESTRICTIONS IN AM FOG AND HAZE POSSIBLE. SAT-SUN...MAINLY VFR BUT WITH AFTERNOON THUNDERSTORMS POSSIBLE... MANLY WEST. && .EQUIPMENT... STATE COLLEGE RADAR IS BACK UP AND IN NORMAL OPERATING MODE AS OF 23Z THIS EVENING. && .CTP WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...LAMBERT/LA CORTE NEAR TERM...LAMBERT/LA CORTE SHORT TERM...LA CORTE LONG TERM...GARTNER AVIATION...LA CORTE EQUIPMENT...LAMBERT
