Area Forecast Discussion National Weather Service Pittsburgh PA 1211 AM EDT Tue Sep 17 2024 .SYNOPSIS... Approach of a coastal low will raise precipitation chances mid week but mainly favor areas southeast of Pittsburgh while having a low probability of dissipating drought conditions. Above average temperature is likely for most of the next week. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... KEY MESSAGES: - Increasing cloud cover and low probability showers expected with coastal low approach ------------------------------------------------------------------- Late Evening Update... The 00Z PIT sounding continued to show very dry air below 400 mb, with moisture and cirrus above. With the dry air in place, maintained only slight chance pops late tonight for Tucker county, as moisture increases on the northern side of the low centered across the SE CONUS. Early Evening update... No major changes needed. Latest hires model data has slowed the chance for rain late tonight over mainly Tucker county. The slight chance/chance PoPs were updated to reflect this. Previous discussion... The slow northward movement of a Carolina low and its associated moisture plume will gradually increase areal coverage/thickness of cirrus overnight. Upslope flow and increasing moisture will increase mostly light rain shower chances for the higher terrain of WV after midnight. Otherwise, the greater cloud coverage should limit nocturnal cooling. && .SHORT TERM /6 AM THIS MORNING THROUGH THURSDAY NIGHT/... KEY MESSAGES: - Periodic rain chances midweek as coastal low meanders around the Mid-Atlantic - Probabilities remain low in seeing 1" or greater of rainfall ------------------------------------------------------------------- There remains fairly high consensus for the coastal low to meander around the Carolinas to Mid-Atlantic vicinity midweek as its parent trough remains detached from the broader northern jet streams. Drawing Atlantic moisture around its periphery will lead to fairly robust cloud coverage across the forecast area while embedded wave dynamics foster bands of precipitation. The main question remains the exact low positioning, with two scenarios (centered along NC coast; centered over central VA) is the most likely outcomes. The farther southern positioning would favor accumulating rainfall primarily to just the WV high terrain, leaving periodic sprinkles for the area Tuesday night through Thursday. The northern positioning would better bring synoptic rain bands into the Upper Ohio River valley and offer periodic wetting rains. Either solution is unlikely to offer a great deal of hope for easing drought conditions; 72 hour probabilities for greater than 1" are less than 10 percent outside of the WV high terrain and even there the percentage is only 30. There remains high confidence that the coastal low influence will begin to wane Thursday night by sagging southeast. Expect a west to east gradient in changes to both temperature (higher), cloud cover (lower) and precipitation chances (lower). && .LONG TERM /FRIDAY THROUGH MONDAY/... KEY MESSAGES: - Above average temperatures return - Dry weather next weekend ------------------------------------------------------------------- Long range ensembles favor a highly amplified pattern of positively titled ridging over the Great Lakes, a detached saggy trough near the SE coastline, and shortwave troughs traversing the northern Rockies. This portends to high confidence in resumption of above normal temperature and dry weather for the Upper Ohio River Valley. Variance in this solution lays in the degree of ridge amplification for the Great Lakes and/or whether phasing can develop between the sagging SE CONUS trough and a deeper low near Nova Scotia. && .AVIATION /04Z TUESDAY THROUGH SATURDAY/... VFR is expected through the TAF period as mid and high clouds increase ahead of a low pressure system slowly approaching from the south. A few stratocu clouds are also possible with some limited increase in moisture at around 5kft on Tuesday. With the Upper Ohio Valley region on the northern side of the low, expect a persistent east wind at 5-10kt. .Outlook... Occasional restrictions and showers are possible, especially near MGW, Tuesday night through Thursday as the low slowly tracks across the Lower Ohio Valley and Appalachians region. VFR is then expected through Saturday as high pressure builds in. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. && SYNOPSIS...Frazier NEAR TERM...WM/22/Frazier SHORT TERM...Frazier LONG TERM...Frazier AVIATION...WM
