Area Forecast Discussion...UPDATED National Weather Service Pittsburgh PA 1254 AM EDT Thu May 23 2024 .SYNOPSIS... Showers and storms are possible today mainly south of Pittsburgh. Seasonably warm highs today. Periodic thunderstorm chances are expected through the holiday weekend as a series of upper level disturbances cross the region. && .NEAR TERM /THROUGH TODAY/... KEY MESSAGES: -Showers and storms are possible today, mainly south of PIT as a cool front stalls just south of the region. -Cooler temperatures today, but still seasonable. _____________________________________________________________ For the overnight period...have updated the PoPs to better reflect current conditions and the latest hires guidance. Activity is having a difficult time developing ahead of the slow moving cool front due to a lack of upper level support, a stabilizing atmosphere, and warmer air aloft that is creating a cap that can be seen on the 00Z PIT sounding. Will still keep in the risk for showers/storms overnight, but its looking more isolated to scattered. Temperatures will remain mild. A cool front will drift south and east of the forecast area this morning, stalling over the northern reaches of the Mid-Atlantic region. This will allow for a break from convection for a portion of the morning hours. The question for the afternoon is the path of a shortwave trough which will move eastward in the vicinity of the quasi-stationary front this afternoon. Seeing some differences in model solution with the track of the wave. This is due to the influence of a second, albeit weaker, shortwave that will move across northern Ohio/PA this afternoon. Some of the operational models want to almost phase the two waves allowing for rainfall to spread further north. While, other models want to keep them separate and focus on the northern wave pushing the southern wave further south. Latest blended guidance is trying to find a happy medium, but is focusing the higher PoPs mainly south of I-70 this afternoon. The latest CAM models are leaning toward a more southern track of the wave, keeping much of the area dry. With so much uncertainty for this afternoon will lean heavily on the blended guidance. The resting place of the front and track of the shortwave will also play a role in how much convection can re-fire this afternoon. Obviously a further south placement would keep the higher levels of instability/buoyancy further south, limiting storm development. Cloud cover will also depend upon how far south things settle, as drier air will be spreading southward behind the front. There is a good chance that the I-80 corridor could see plenty of sunshine today. Temperatures will cool a few degrees, but still remain seasonable. && .SHORT TERM /TONIGHT THROUGH SATURDAY/... KEY MESSAGES: - High pressure and brief ridging should keep the area dry Friday. -A crossing shortwave will return the risk for showers and storms Saturday. _____________________________________________________________ Confidence is increasing that dry weather will develop Thursday night into Friday as shortwave ridging crosses the region with high pressure at the surface. Minimal airmass change with slightly higher heights should promote above normal temperature again. Ensembles are leaning toward a wave crossing the region Saturday producing showers and thunderstorms; timing varies, but potential exists for convection to exit east of the area before evening activities. That variability leads to an inconclusiveness on severe potential but note that analogs for the pattern and machine-learning analysis suggests at least a low probability for hazardous weather that day. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... KEY MESSAGES: - Variability remains high on long term forecast and may be predicated on prior day's convective outcomes. - Overall, periodic showers and thunderstorms with slightly above normal temperature is favored through the holiday weekend and into next week. ____________________________________________________________ A more well-organized low pressure system is becoming the favored pattern development to end the holiday weekend as it lifts through the Great Lakes. Higher probabilities for showers and thunderstorms are expected during this time frame but it is unlikely to be "all day" rain type of events. Early analogs for this pattern also suggest at least a low probability for hazardous weather, but much variation in that potential remains. Long range suggests a shift to a cooler, dry pattern by the middle of next week as upper troughing develops over the Great Lakes. Expect temperature to fall below the seasonal average, with Tuesday potentially being the transition day from shower activity to dry weather. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... A general VFR forecast for the period. The best chance for a shower or storm to hit a port would likely be prior to dawn. Have covered this early threat of convection with a tempo group with a brief reduction in vis/cigs possible. This is done with low confidence as probabilities of a storm hitting a port is minimal. Additional showers and thunderstorms may develop this afternoon primarily south of PIT which could return associated chances for restrictions later in the afternoon. .Outlook... Periodic thunderstorm chances and restrictions are likely through the weekend as an active weather pattern continues. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None.
