026 FXUS61 KCTP 141908 AFDCTP Area Forecast Discussion National Weather Service State College PA 308 PM EDT Mon Jul 14 2025 .SYNOPSIS... * Continued seasonably warm and humid for many days * Afternoon and evening focused showers and thunderstorms are expected into the early evening hours. * Flooding possible almost anywhere east of State College and Altoona before midnight. * Tuesday still looks like the driest day of the next seven with a brief visit from high pressure. && .NEAR TERM /UNTIL 1 AM TUESDAY MORNING/... Still focused on flooding as the main issue of the next 8 hrs. Many hot spots around the CWA, but certainly hottest over Lycoming/Sullivan/Columbia counties. But, there are 2-3 other spots already that have needed a Flash Flood warning. Given that the heaviest of the rain seems to be sliding to the east of UNV-AOO right now, it is likely more stable to the west and they may be out of the woods. However, latest HRRR does redevelop a little deep coinvection over Centre Co in a couple of hours. We will consider dropping some of the watch, but not sure it is wise to do so until closer to 5 or 6 PM allowing the trend to become more certain. && .SHORT TERM /1 AM TUESDAY THROUGH 6 AM TUESDAY/... The rain should be over for all but really isolated spots after sunset most everywhere, and by 11 PM in the far SE. Then, we`ll just be watching for the fog to form. Have drawn a widespread fog over all of the CWA tonight. A dense fog advy appears likely, but we`ll wait for the fog to show it`s hand for that to be posted. Very slightly drier air is moving in from the NW. Tuesday appears very much dry for the great portion of the CWA. However, the high pressure advnacing from the NW is not strong at all, and the southern border will still be at risk for sct SHRA/TSRA. Virtually no risk of wind/hail tmrw, but still a SLGT risk of excessive rainfall. The locations that have thus far (330 PM) received the most rain/worst flooding have a very low chc of rainfall. However, Lancaster Co will be a close call for additional rainfall over the area getting too much right now. && .LONG TERM /TUESDAY THROUGH MONDAY/... The cold front pulls slowly moves through the area Monday evening into Tuesday morning, allowing for a brief period of no precipitation across central Pennsylvania through the morning hours on Tuesday. This will be short-lived, however, as the front will move back in to the southern tier Tuesday afternoon and trigger another round of showers and thunderstorms. Large-scale pattern remains fairly consistent, allowing for continued chances for diurnally driven showers and thunderstorms across central Pennsylvania throughout much of the long-term forecast period. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... Approach of a deeper upper trough from the west is a good signal that storms will form again midday Monday. Will just mention after 16Z. Most of the storms will be SE of IPT-UNV-AOO depending on timing of the trough axis, but a few are possible to the NW of that area. Outlook... Tue-Wed...Mainly VFR. Isold-Sct PM TSRA poss, mainly south. Thurs-Fri...Sct/Nmrs SHRA/TSRA. && .CTP WATCHES/WARNINGS/ADVISORIES...
