Corrected aviation paragraph... Dry weather is expected through the day under shortwave ridging. Mid/high clouds should continue to cross the area tonight on the wrn periphery of a coastal low. Broken stratocu is expected today after sunrise in cold NW flow, though this is expected to gradually decrease as dry air mixes down during the day. Temperatures are expected to be 10 to 15 degrees below seasonal levels.

&& .SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/... High pressure building over the Great Lakes will keep conditions dry into the weekend. Low pressure will then track south of the region, clipping southern portions of the forecast area with precipitation Saturday and Saturday night. Temperatures will likely allow precip to start as snow, change over to rain during the day, then finish as snow. Temperatures will remain well below normal. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... Sunday and Monday will be dry with high pressure across the region again. Low pressure will track from the central Plains on Tuesday to Michigan on Wednesday. Precipitation will spread east in advance of the low. Temperatures should be warm enough during this time period that locations south and west of Pittsburgh should generally receive rain, while locations north and east will have snow mix in at night. && .AVIATION /04Z THURSDAY THROUGH MONDAY/...

General VFR is expected although high-end MVFR stratocu is expected to mar the sky as mixing gets underway with NW flow late this morning. Sufficient temp/dewpoint spread should alleviate the base-nuisance in the afternoon despite the approach of a disturbance with upper flow. Sfc gusts near 20kt can be expected until decoupling starts toward evening. OUTLOOK... MVFR restrictions are possible Friday with another crossing disturbance.
