Area forecast discussion, Jul 15, 11:27 PM EDT, 2 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 1127 PM EDT SUN JUL 15 2012 .SYNOPSIS... THE LARGE SCALE PATTERN IS TRYING TO BUILD A LARGE RIDGE OVER THE WESTERN UNITED STATES AND A TROUGH OVER THE NORTHEASTERN UNITED STATES. THIS FAVORS COOLER AND DRIER WEATHER LATER THIS WEEK...ABOUT THURSDAY AND INTO THE COMING WEEKEND. BUT THE FRONTAL SYSTEM THAT SHOULD HELP CARVE OUT THE TROUGH WILL PULL SOME VERY WARM AIR INTO PENNSYLVANIA FROM THE WEST. MONDAY WILL BE WARM AND TUESDAY AND MOST OF WEDNESDAY SHOULD BE HOT. MOISTURE AHEAD OF THE FRONTAL SYSTEM FAVORS SHOWERS AND THUNDERSTORMS LATE WEDNESDAY OR EARLY THURSDAY. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... MOST OF THE SHOWERS AND STORMS IN SOUTHEASTERN SECTIONS ARE FINALLY SUBSIDING AND/OR SLIDING EAST. SOME ROADS AND POOR DRAINAGE AREAS WILL TAKE SOME TIME TO DRAIN OFF THE WATER. TWO OTHER AREAS OF WEAKENING SHOWERS ONE OVER THE NORTHWEST ANOTHER IN THE SOUTHWEST MOUNTAINS. ALL APPEAR TO BE WANING. IR IMAGERY SHOWS HOPE OF LOWERED CHANCE SHOWERS. THOUGH WITH THE RAIN THE POTENTIAL FOR PATCHY FOG IS PRESENT. SIMPLY PUT IT IN ALL THE GRIDS AFTER 2 AM UNTIL SHORTLY AFTER SUNRISE. MOST AREAS WILL BOTTOM OUT IN THE 60S. THIS AIR MASS IS DRIER BUT NOT MUCH COLDER THAN THE ONE IT REPLACES. IT CAME FROM THE ANOMALOUS RIDGE TO OUR NORTH OVER CANADA. BUT A RELATIVELY DRIER NIGHT SHOULD BE GOOD. && .SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/... DESPITE THE FRONTAL SYSTEM THAT CAME THROUGH. MONDAY WILL BE ON THE WARM SIDE. THE 850 HPA TEMPS WILL BE ABOUT 16C TO BEGIN THE DAY AND 18C TO END IT. THE LATTER IS ABOUT 1 SIGMA ABOVE NORMAL. WILL BE A WARM LATE AFTERNOON. GOOD NEWS IS THE PW VALUES ARE IN THE 28-30MM RANGE COMPARED TO THE 48-50MM RANGE. THE AIR IS CONSIDERABLY DRIER AND KEPT ANY POPS IN ONLY SLIGHT CHANCE AND KEPT MOST AREAS WITH POPS BELOW 10 PERCENT. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... MADE MINOR MODIFICATIONS TO FORECAST. KEPT IT HOT ON TUESDAY BUT LOWERED POPS A BIT. PW BEGINS TO RISE OVERNIGHT TUESDAY INTO WEDNESDAY. FRONTAL TIMING IS CRITICAL TO THE WEDNESDAY FORECAST. GRIDS ARE STILL WARM BASED ON POST 18Z FROPA. SURGE HIGH PW AIR LATE WEDNESDAY IMPLIES POTENTIAL CONVECTION AND RAIN POTENTIAL WED AFTERNOON AND EVENING. CLOSE REPLAY OF TODAY? UPPER TROFFING IS FORECAST BY MEDIUM RANGE GUIDANCE TO DEVELOP OVER EASTERN CANADA THROUGH MIDWEEK THEN BEGIN LIFTING OUT OVER THE WEEKEND. THIS TROF WILL SERVE TO SUPPRESS THE NORTHERN FRINGE OF THE SUBTROPICAL RIDGE/BERMUDA HIGH THAT HAS BEEN DOMINATING THE EASTERN SEABOARD. SHORTWAVE ENERGY WITHIN THE TROF WILL SUPPORT THE PASSAGE A COLD FRONT AROUND WEDNESDAY BRINGING THE HIGHEST CHANCE OF SHOWERS/TSTMS FOR THIS PD. COOLER AND DRIER AIR IS STILL EXPECTED BEHIND THE FRONT...WITH SLIGHTLY BELOW NORMAL TEMPS PROGGED FOR NEXT WEEKEND. AHEAD OF THE FRONT YET MORE HOT AND DRY WEATHER IS INSTORE FOR CENTRAL PA. && .AVIATION /04Z MONDAY THROUGH FRIDAY/... LAST OF THE CONVECTION JUST MOVING OUT OF THE AREA. SEVERAL UPDATES TO THE TAFS DONE. REDUCED VSBYS IN PATCHY FOG POSSIBLE OVERNIGHT...AND SOME LOW CLOUDINESS MAY FORM...ESPECIALLY ACROSS THE WESTERN HIGHLANDS /JST AND BFD/ AS FLOW BECOMES LIGHT WESTERLY AND UPSLOPE. MONDAY WILL GENERALLY BE VFR AFTER ANY MORNING FOG AND LOW CLOUDS BURN OFF. AN ISOLATED AFTN SHRA/TSRA IS POSSIBLE...MAINLY ACROSS THE SOUTH. THE NEXT CHANCE FOR SIGNIFICANT WX WILL COME ON WEDNESDAY...AS AN APPROACHING COLD FRONT TRIGGERS SCT SHRA/TSRA. OUTLOOK... TUE...VFR. WED...SCT TSTM IMPACTS LKLY ASSOCD WITH COLD FROPA.
