899 FXUS61 KCTP 291747 AFDCTP Area Forecast Discussion National Weather Service State College PA 147 PM EDT Fri Aug 29 2025 .SYNOPSIS... * Chilly fall-like pattern with low humidity continues today through Sunday. * Meteorological Fall (September 1) kicks off with continued pleasant and dry conditions and a gradual warmup for Monday through Wednesday. * Cooler than normal temperatures will likely be observed across most of the area today into tonight. && .NEAR TERM /THROUGH TONIGHT/... Consistent northwesterly flow today is keeping our high temps 5 to 10 degrees F below normal for this time of year across the central mountains and up through northwestern Pennsylvania. Fair weather cu will continue to spread across the area this afternoon making for a pleasant end to the work week. High pressure will build into the south east portions of the state late tonight and should become centered over Central PA Saturday. Clouds will clear overnight and winds will become calm, making ideal conditions for efficient radiational cooling and lows well into the lower 40s across much of the CWA. Across the northwest mountains near Bradford temperatures could dip into the upper 30s with some spots possibly developing localized frost in the coldest places. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... Saturday will feature a prolonged return to mostly sunny skies, low daytime humidity with excellent vsby and high temps in the upper 60s to mid 70s from the northern and western high terrain, to the Valleys of Scent and SE PA. Strong high pressure will firmly be in place by Saturday afternoon. The center of the high will be located over the southern Great Lakes region. The fall like conditions will be here to stick around for the end of August. && .LONG TERM /SUNDAY THROUGH THURSDAY/... High pressure from north-central Canada will keep it (very) dry for the second half of the weekend. The compact upper low just to our NE will finally lift away before the start of the work week, but troughiness remains. The sfc high should fend off rainfall until the second half of the upcoming week. However, low level southeast flow could make for some pesky low clouds at times. Temps rise only slightly for the first half of the week (maxes in the 70s and lower 80s). The next chance for rain will not arrive until late Wednesday into Thursday as the next spoke of the upper level trough swings down from central Canada to bring another cold frontal passage to the Mid-Atlantic and New England regions. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... Widespread VFR conds were found across Central PA early this afternoon, beneath partly sunny skies with a northwesterly sfc breeze occasionally gusting 15-20 kts. Winds will diminish this evening. Some model guidance is suggesting that there could be fog and/or low clouds across the NW mtns overnight. However, confidence is low enough that decided to leave it out of the TAFs for now. Otherwise, expect continued VFR conds. Regardless, Saturday should feature plentiful sunshine and widespread VFR conds areawide. Outlook... Sat-Tue...AM valley fog possible; otherwise predominantly VFR. && .CLIMATE... Altoona set a record low temperature yesterday (8/27) of 43 degrees (45 in 1958). && .CTP WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...Lambert/Bowen NEAR TERM...Bowen SHORT TERM...Bowen LONG TERM...Bowen AVIATION...Evanego CLIMATE...Dangelo
