Area Forecast Discussion National Weather Service Pittsburgh PA 542 AM EDT Tue Jul 16 2024 .SYNOPSIS... Storm chances continue across the Ohio River Valley before drier weather and seasonable temperatures return behind a Wednesday cold front. && .NEAR TERM /THROUGH WEDNESDAY/... KEY MESSAGES: - Active weather continues until the passage of a cold front on Wednesday. - Continued well above normal temperatures. __________________________________________________________________ Uncertainty in the forecast continues as upstream development will largely dictate our weather until the passage of a Wednesday cold front. Convection will be possible again this afternoon. Damaging wind remains the main threat, though isolated tornadoes and large hail can note ruled out. Similar to Monday, the source of uncertainty surrounds weak forcing and storm development. Cloud coverage and subsidence in the wake of the remnants of a morning MCS should limit development for much of the day. Actually, the majority of CAMs suggest limited development. If storms remain cold pool- balanced, the tornado threat may be a bit higher, otherwise, winds will remain the primary threat in downbursts with sufficient dry air in the mid levels. SPC has maintained the Slight Risk across the region for today. A more stout shortwave trough dropping into the Great Lakes on Wednesday will finally help to push a cold front along for an eventual Wednesday afternoon/night passage, bringing a more concentrated precipitation area Wednesday, but then an end to the convective threat behind it. Heat and humidity will continue to be part of the story during the early part of the week. The potential for advisory-level heat index values of 100 or more on Tuesday depending on convective extent and timing. The current forecast update tended towards the higher end of temperature guidance, although at this time there is only about a 15% chance we exceed advisory criteria. The only way that we realize that at this point is mostly clear skies. Guidance still has a large spread on cloud cover dependent on the progression of the aforementioned overnight MCS. Will keep an eye on things, but confidence was too low to issue and products for tomorrow at this point. Nonetheless, cumulative heat stress will approach major stage for most, so avoid prolonged exposure to the elements and stay hydrated. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... KEY MESSAGES: - A drier and cooler pattern will ensue on Thursday and continue into next weekend. _________________________________________________________________ Dry and cooler conditions return Thursday with expanding high pressure across the Great Lakes and northeast CONUS into next weekend. With much drier air in place conditions will be much more comfortable with dewpoints back down into the 50s. && .LONG TERM /SATURDAY THROUGH MONDAY/... KEY MESSAGES: - Diurnal shower/storm chances increase slightly with increased moisture. ------------------------------------------------------------------- Rising heights Saturday/Sunday in response to increased troughing over the Central Plains may bring moisture back from the south, leading to increased diurnal precipitation chances, mainly southeast of Pittsburgh. This will also result in a warming trend through the weekend. && .AVIATION /10Z TUESDAY THROUGH SATURDAY/... VFR is expected through much of the day. Mixing will likely result in SW wind gusts to 20kt by mid morning. CU rule and model soundings indicate a scattered to broken CU layer will develop by mid to late morning as convective temperatures are reached. Models differ on the extent and timing of convective development through the day. Most guidance indicates a shortwave will track across the region from late morning through the afternoon. Included Prob30 for thunder and restrictions at each airport for the most likely time of occurrence, tied to the timing of the shortwave passage. Convection should wane Tuesday evening as instability wanes, and with a lack of forcing. .Outlook... Cig/vsby restrictions are possible Tuesday night/Wednesday morning with patchy low level moisture in place. Showers and thunderstorms, and associated restrictions, are likely with the passage of a Wednesday cold front. VFR returns Thursday through Saturday under building high pressure. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None.
