000 FXUS61 KCTP 232119 AFDCTP AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 519 PM EDT WED APR 23 2014 .SYNOPSIS... HIGH PRESSURE WILL BUILD IN FROM THE GREAT LAKES OVERNIGHT. COOL AND DRY WEATHER IS EXPECTED TO CONTINUE THURSDAY...AS THE HIGH SLIDES EAST OVER THE AREA. CLOUDS WILL INCREASE THURSDAY NIGHT AND ANOTHER COLD FRONT WILL BRING OUR NEXT CHANCE FOR SHOWERS ON FRIDAY. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
-- Changed Discussion --
AN EXTENSIVE BLANKET OF COLD AIR STRATO-CU REMAINS OVER THE AREA LATE THIS AFTN...AS THE LOW LEVEL THERMAL TROUGH MOVES OVR THE REGION. SETTING SUN...COMBINED WITH ARRIVAL OF MUCH DRIER AIR ON NW FLOW WILL PRODUCE CLEARING SKIES THIS EVENING. LATEST RAP SOUNDINGS AND LAMP GUIDANCE SUGGEST CLEAR SKIES ACROSS MOST OF THE AREA BY 00Z. THE WIND WILL REMAIN FAIRLY GUSTY INTO THE OVERNIGHT OVER CENTRAL AND EASTERN AREAS...BUT WILL DIMINISH TO LIGHT AND VARIABLE OVER THE WEST WHERE THE GRADIENT WILL SLACKEN IN RESPONSE TO THE HIGH MOVING IN. WHILE TEMPS WILL BOTTOM OUT IN THE FROSTY LEVELS IN OUR COUNTIES WHERE THE GROWING SEASON HAS TECHNICALLY BEGUN...THINKING IS THAT THE WIND WILL KEEP FROST AT BAY. NO HEADLINES ARE PLANNED AT THIS JUNCTURE FOR THE POCKETS OF FROST AND NORMAL CHILLY AREAS WHERE LOWS WILL DROP TO NEAR FREEZING. OVERALL LOWS TONIGHT WILL BE QUITE CHILLY FOR THE SEASON...RANGING FROM THE MID TO UPPER 20S ACROSS THE NRN AND WRN MTNS...TO THE MID 30S IN THE SOUTHEAST. THIS WILL AVERAGE SOME 5 TO 10 DEGREES BELOW NORMAL.
