Area Forecast Discussion National Weather Service Pittsburgh PA 146 PM EDT Sun May 10 2020 .SYNOPSIS... Thunderstorm chances will increase late this afternoon and continue into the evening as cold front advances; a few storms may be strong. && .NEAR TERM /THROUGH TONIGHT/... Pre-frontal rain showers have continued to overspread the Ohio River Valley this afternoon as a low pressure system strengthens across the Great Lakes. A broken squall line is currently developing in eastern Indiana along the cold front boundary. Cyclogenesis will continues as the low pivots over Lake Erie, and the squall line will become more defined as it advances east into Ohio. Strong southwest flow (warm, moist advection) near the surface and cold air (-27 C at 500mb) embedded in the mid level trough, will increase low and mid-level lapse rates and help destabilization of the atmosphere in eastern Ohio/western PA/northern panhandle of WV. Surface CAPE values will increase but be marginal (less than 500-600 J/kg). Any strong storms that form this evening will mostly be due to jet dynamics as the mid- level jet increases to 50kts; thus, damaging wind will be the main threat today. Marginal severe hail is not out of the question despite limited CAPE aloft; low-level freezing levels will ensure that ice particles reach the ground. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... A surge of cold air (-5c at 850mb) on the backside of the low will support a change/mix of rain to snow for most areas by early Monday morning. A shallow warm boundary layer should preclude accumulation, but lighter amounts are not out of the question for elevations above 2,000ft; Tucker County may see up to an inch with strong orographic lift. Despite the cool air aloft, temperatures will stay near or just above freezing; a Freeze Warning will not be issued in the ridges with this forecast package. Precipitation will taper off Monday evening with subsidence and dry advection as surface high pressure builds under continued broad and cold upper troughing. That pattern should maintain continued cold, but dry conditions into mid week. Freeze headlines may need to be issued for portions of our region early Tuesday and Wednesday morning. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... A pattern shift is indicated for the latter half of the week as flow flattens. Temperature will quickly moderate and rise above the averages by weeks end while precipitation chance will be shortwave supported and progressive. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... VFR conditions present at the start of the TAF period as shortwave ridging departs, with gusty SW wind of 15 to 25 knots. The next shortwave will bring showers and a few thunderstorms to the region mainly during the evening hours. The best chance of getting thunder will be mainly west of PIT, where the best instability will lie. Storms are expected to congeal into a pre-frontal line, and will likely impact ZZV, HLG, and BVI between 22Z and 01Z. Have included TEMPO thunder for these sites. Kept VCTS for PIT and FKL due to uncertainty that thunder will survive that long, with only SHRA mention at others. Any storm will be capable of producing a brief wind gust to between 35 and 45 knots, as well as a brief MVFR/IFR visibility restriction. FROPA will occur tonight, and ceilings will deteriorate to MVFR/IFR levels with time. Some scattered showers will also linger, with snow starting to mix in late. Slow improvement is likely after sunrise Monday, although MVFR restrictions should continue for the most part. .Outlook... Restrictions are likely again by Wednesday night with the advance of the next area of low pressure. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. &&
