Area Forecast Discussion...UPDATED National Weather Service Pittsburgh PA 1227 AM EDT Mon Mar 31 2025 .SYNOPSIS... Above normal temperatures continue with severe thunderstorms possible tonight into early Monday. A brief bit of drier and cooler weather is expected Tuesday. Heavy rainfall is expected across the Ohio River Valley late week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... KEY MESSAGES: - Line of showers and storms tonight into early Monday with a few possibly severe ------------------------------------------------------------------- A line of showers and thunderstorms continue to track across the area overnight. Recent satellite images show cloud tops warming with this convection, with a gradual weakening trend. There is still shear in place, though recent mesoanalysis shows this is beginning to diminish across the Upper Ohio Valley region. Cancelled the Severe Thunderstorm Watch west of where the current line is, as the severe potential has ended. Will monitor trends over the next couple of hours for futher adjustments. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TUESDAY/... KEY MESSAGES: - Cold front expected to cross the region slowly on Monday ------------------------------------------------------------------- By 6am Monday morning, showers and storm will likely still be advancing through the region. The cold front may be positioned over central Ohio, a noted delay due to the upper-level wind field running parallel along the front. If the front progressives faster, this could set up a favorable time window for much of our region to avoid the brunt of any severe weather early on Monday. Model consensus is very strong in showing most of the destabilization Monday well east of the ridges towards the I-81 corridor. This leaves a non-zero but low chance that impactful severe storms can fire along the front bright and early Monday morning as the front crosses the remainder of our region. Confidence is high that by 6pm the front will be at least passed counties northwest and west of Allegheny County (Mercer/Venango/Lawrence/Columbiana). Temperatures will remain well above normal Monday after within the warm sector. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... KEY MESSAGES: - A cool-down is most likely Monday night into Tuesday. - Above average temperatures Wednesday through Friday. - Potential for heavy rain Thursday into Saturday ------------------------------------------------------------------- Dry and cooler conditions settle in Tuesday behind the cold front. Both are rather short-lived as another system climbs through the Upper Midwest on Wednesday dragging a warm front back through the region. This ushers in the return of above normal temperatures and rainfall. There looks to be potential for a boundary to stall across the Ohio Valley beginning late-week and lasting into the weekend. The exact placement and any further wobbling of this stationary boundary will be very important to the expected impacts but it looks likely that somewhere in the OH Valley is in for rounds of rainfall and the possibility of high water impacts. It remains very early to say exactly where these impacts will be greatest but clustered analysis. Long-range ensembles yield several days next week where the chance to see >1 inch of rainfall in 24hrs is above 30% in our region. There is also a noted 50% chance of some rivers reaching 'Action' stage, including downtown Pittsburgh. && .AVIATION /06Z MONDAY THROUGH FRIDAY/... First area of showers and thunderstorms will move through all ports early in the forecast period. This will bring tempo restrictions to vis/cigs. MVFR cigs are generally favored through the rest of the forecast period. Another round of scattered showers are possible during the morning and early afternoon hours with the passage of the cold front. Showers look to be non-restrictive. Wind gusts should strengthen during the morning hours, with gusts of 20 to 25 mph possible. Winds will be backing rapidly once the cold front crosses, so a switch from southwest to northwest should be expected. Outlook... VFR returns Tuesday under high pressure. Low pressure may bring another round of rain and restrictions Wednesday into Thursday with an unsettled pattern continuing to close out the week. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None.
