Area Forecast Discussion National Weather Service Pittsburgh PA 354 AM EDT Tue Aug 27 2024 .SYNOPSIS... Hot and humid today and Wednesday. Strong to severe storms could develop Wednesday afternoon. Conditions will remain warm, muggy and unsettled through the end of the week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... KEY MESSAGES: - Hot, humid and mainly dry weather today. - Heat indices in the mid to upper 90s for much of the region. ------------------------------------------------------------------- Slow height rises expected today as a large ridge builds into the midwest. With plenty of sunshine, and warm air advection, high temperatures will push into the 90s for much of the forecast area. For most of Ohio, northern WV and Southwest PA, NBM probs of max T>90 range from 90 to 100%. Further north in western PA, probs max T >90 fall off to 50 to 80% with locations north of I-80 seeing low probs for temps greater than 90. Probs of max T > 95 really fall off with portions of Ohio ranging close to 50 to 60%, while most of northern WV and W PA are showing probs less than 30%. Heat indices will be quite toasty as well with surface dewpoints in the 60s to low 70s for much of the day. We may see dewpoints decrease a bit later this afternoon as mixing increases and begins to bring drier air down to the surface. Heat indices look to remain below advisory levels with low to upper 90s possible this afternoon. With the building ridge, and lack of much forcing, NBM probs for measurable rainfall are less than 5%. Some of the deterministic models want to try and bring a late day shortwave over top of the ridge and drive it southward. This feature looks rather weak and will be fighting the amplifying ridge. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... KEY MESSAGES: - There is a slight risk for severe storms on Wednesday, with showers and thunderstorms expected mainly in the afternoon and evening. - Well-above normal temperature continues, with heat indices near 100F in some areas. - Temperatures remain well above normal Thursday with a continued threat for convection. ------------------------------------------------------------------- High uncertainty on the convection threat and high temperatures on Wednesday. This will also have an impact on the heat indices as well. Differing model solutions on shortwave/surface cold front impact Wednesday afternoon. This would have an effect on the strength of the ridge, cloud cover, precipitation initiation and timing, and ultimately the high temperatures. Ensembles are showing a series of shortwaves moving over top of the ridge and flattening it tonight and Wednesday. At the same time, a weak surface cold front is shoved southward as heights fall. None of the large scale ascension is very strong on Wednesday, as the main shortwave looks to remain well to the west of the area. However, with the cold front crossing, this would likely spark showers and storms as it does so. Current NBM probs are not high for measurable rainfall and thunder, generally less than 40%, but this would be a place to lean on the CAMs to pick up on the more mesoscale features. Instability will increase on Wednesday, but current CAMs are keeping the most buoyant air to our west and to our east. Wind shear will also increase, with 20 to 25kts anticipated as the front crosses. Limiting factors for stronger convection on Wednesday will be the very warm air aloft and increasing cloud cover as the ridge breaks down and the front pushes through. Current NBM highs and surface dewpoints look a little over done considering the setup. Will back of to closer to the 25th percentile to cover these features. A slight risk (2/5) for severe storms remain on Wednesday, with the primary threat being damaging wind. Another minor and brief amplification of the ridge is possible on Thursday. The cold front, that should cross the region on Wednesday, will likely stall somewhere over the Mid-Atlantic region and sit there through most of the day. Another shortwave will cross the area Thursday afternoon keeping in the risk for showers and storms. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... KEY MESSAGES: - Temperatures remain well above normal through Friday. - Temperatures will cool a bit over the weekend, with an increasing threat of showers and storms Friday into Saturday. - Dry weather looks to return for the end of the long term period. ------------------------------------------------------------------- Ensembles indicate amplifying central-CONUS ridging by late week, renewing northwest flow over the area and bringing some relief from the heat. A more potent cold front is progged early weekend, which may return more widespread rain chances to the area. && .AVIATION /08Z TUESDAY THROUGH SATURDAY/... Patchy MVFR to IFR fog is expected through early morning for FKL, DUJ, and LBE, with low level moisture in place due to recent rainfall. Elsewhere, VFR is expected through Tuesday night as upper level ridging builds in. CU rule and model soundings indicate a scattered cumulus layer will develop by mid morning on Tuesday. There could be an isolated afternoon thunderstorm near FKL and DUJ, as a weak shortwave crosses on the northern periphery of the ridge. Confidence in occurrence is too low for TAF inclusion at this time. .Outlook... Periodic restrictions in scattered showers and thunderstorms are possible Wednesday through Saturday with a series of crossing disturbances. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None.
