&& .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... Ridging will continue to build through midweek with a drying boundary layer and overall subsidence supporting a dry, seasonable forecast through Wednesday night. && .LONG TERM /THURSDAY THROUGH MONDAY/... Models show decent continuity in the extended with an upper level trough and associated front crossing the forecast area Thursday through Friday morning. Showers and storms along the boundary are likely. Overall model consensus shows troughing east of the forecast area by Friday evening...and with drier, more stable air moving in behind....a dry and sunny weekend is most probable at this time. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/...
-- Changed Discussion --
Low-end VFR or high-end MVFR ceilings will dominate this morning as a stratus deck lingers. Terminals near/north of I-80 will flirt with IFR. Fog is limited to river valleys south of the stratus deck. Ceilings will slowly lift and then break up during the afternoon, leaving VFR conditions for the balance of the forecast. Some valley fog is possible again tonight but impact on terminals should be minimal. Light winds out of the north are expected. .OUTLOOK... VFR conditions will continue through Wednesday night. Restriction chances return Thursday as low pressure impacts the Ohio Valley.
