380 FXUS61 KCTP 040818 AFDCTP Area Forecast Discussion National Weather Service State College PA 418 AM EDT Tue Aug 4 2026 .WHAT HAS CHANGED... * No significant changes && .KEY MESSAGES... 1) Short break in the muggy precip pattern today 2) Warmer/more humid with heavy downpours Wed-Sat && .DISCUSSION... KEY MESSAGE 1: Short break in the muggy precip pattern today Sat RGB composite shows the expected fog in the valleys. This should dissipate by 8 or 9 AM in most places but could take until 10 AM in the deeper places. After that, only some higher clouds moving north out of the SE and isold cu, mainly over the NW. Temps not too different from Mon, just a shade warmer in the Allegheny Plateau and Laurel Highlands. RH dips into the 40s and lower 50s for everyone this aftn. ------------------------------------------------------- KEY MESSAGE 2: Warmer/more humid with heavy downpours Wed-Sat Upper low over GA will open up and get absorbed by the longer- wave trough moving across the nrn Plains and upper Great Lakes. The resulting SSE flow of high PWAT air and lack of well-defined fronts and will put us back into a muggy and unsettled pattern. The lack of organization will mean more pulse/airmass type thunderstorms. The high moisture content will make heavy downpours likely. But, targeting where they will be on any specific day is going to be too difficult at this range. River gauges already show a return to base flows in most places that received the very heavy rainfall and flooding the other day. Thankfully, the coverage shouldn`t be too dense Wed and Thurs. The expected isolated/sct coverage should give the ground a little more time to dry out. But, with each day, the coverage should become more complete. Each successive day should also yield a slightly higher worry for flooding. At this point, the WPC outlooks remain in the next-to-lowest (marginal) category, just above no worries, for W,R,F & Sat which is almost certainly a nod to the scattered nature of the expected airmass/pulse storms. && .AVIATION /07Z TUESDAY THROUGH SATURDAY/... Some fog at BFD during the last hour. Expect the fog there to become more widespread until shortly after sunrise. Elsewhere expect mainly VFR conditions through this evening. Some chance of fog at spots like IPT and UNV, but a bit less likely at these sites. Expect winds today to be not real strong. Very dry air aloft at sunset Monday evening, will result in mainly dry conditions today and at least the first part of Wed. Higher dewpoint air likely to push into the southern part of PA after 06Z Wed. Outlook... Wed...Restrictions possible with SHRA/TSRA, especially in the south. Thu...AM fog possible. Afternoon SHRA/TSRA. Fri-Sat... Daily chances for showers and isolated t-storms. Low VFR to MVFR conditions prevailing most of the time. && .CLIMATE...
