Area forecast discussion, Jun 10, 9:10 PM EDT, 13 minutes before
Area Forecast Discussion...UPDATED National Weather Service Pittsburgh PA 910 PM EDT Wed Jun 10 2020 .SYNOPSIS... A cold front will support showers and thunderstorms this evening. Some storms may be severe. Dry weather will return Thursday under building high pressure, with temperature returning to near average through the end of the week. && .NEAR TERM /THROUGH THURSDAY/... Have cleared part of the watch in Ohio behind the main line of convection. PoPs were updated to reflect current radar trends. Previous discussion... Effective shear and instability will increase as the associated negatively tilted trough tracks east this evening and a line of storms capable of producing damaging wind will cross this evening ahead of the cold front. && .SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... Dry conditions return on Thursday with building high pressure behind the front. It will be noticeably more comfortable with dewpoints back down into the 50s and daytime highs in the upper 70s. A weak front is progged to drop south over the area later on Friday but conditions should remain largely dry with limited moisture...mainly just resulting in increased cloud coverage. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... A persistent upper trough/low is expected to remain across most of the Eastern CONUS through the long term period. A sfc ridge under the trough/low should maintain mainly dry weather through much of the period, though slight to low rain chances are possible on occasion as waves rotate around the low. Cooler than average temperatures should recover to seasonable levels toward mid week. && .AVIATION /01Z THURSDAY THROUGH MONDAY/... Expect VFR conditions with a period of MVFR cigs and vis as a line of storms pass through the region during the evening hours, generally from 00Z through 06Z. Behind the convection, lingering MVFR cigs can be expected for an hour or two before a return to VFR. A second front will approach the area around dawn. This boundary will bring a period of restrictive MVFR cigs which will hang around through much of the morning hours. A return to VFR is expected during the afternoon. Gusty surface winds through a couple of hours after FROPA. No substantial wind direction shift is expected until Thursday afternoon. .Outlook... VFR will largely prevail through the next several days. && .CLIMATE... Record high temperature for June 10: PIT...94F (1911) ZZV...95F (1911) MGW...98F (1933) DUJ...87F (2012, 1984) HLG...94F (1936) PHD...93F (1999) && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None.
