Area forecast discussion, Jul 14, 3:52 PM EDT, 1 hour 44 minutes before
Area Forecast Discussion National Weather Service State College PA 352 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 convection 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 advancing 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/... Latest hires guidance/12Z HREF 3hr PMM shifts heavy rain threat to the south of the MD line for Tuesday afternoon. This should result in a reduced ERO risk with later updates from WPC. The flash flood risk ramps back up on Wednesday with the return of deep moisture/forcing after the reprieve on Tuesday. The remainder of the week looks seasonably warm/humid with daily rounds of scattered convection during the afternoon and evening. Heat risk peaks in the major category on Thursday afternoon with max HX values peaking around between 98-102F in the Lower Susquehanna Valley. There still appears to be a minimum in POPs on Saturday with more unsettled wx Sunday into early next week. && .AVIATION /20Z 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... Flood Watch until midnight EDT tonight for PAZ012-018-019- 025>028-034>037-041-042-045-046-049>053-056>059-063>066. && SYNOPSIS...Dangelo NEAR TERM...Dangelo SHORT TERM...Dangelo LONG TERM...Steinbugl AVIATION...Dangelo
