&& .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/... Strong ridge will build in over the area tonight and hold through most of Wednesday. A shortwave trough will move into Western Ohio late Wednesday and begin the process of shifting the ridge axis to the east. With a lack of moisture and subsidence under the ridge, most of Wednesday should remain dry. A late day shower or storm cannot be ruled out over Ohio as the shortwave will increase large scale ascent over a destabilized lower atmosphere. Very warm Wednesday with temperatures 10+ degrees above normal. Shower chance will increase across the entire area Wednesday night, as aforementioned shortwave continues it slow trek eastward. It will take most of Thursday for the trough axis to make it through, necessitating the inclusion of pops through much of the day. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... Ensembles are in good agreement that a broad and rather strong ridge will develop over the Eastern US through the much of the long term. This will provide the area with very warm temperatures and increasing levels of humidity. && .AVIATION /08Z TUESDAY THROUGH SATURDAY/... High pressure will maintain VFR at all terminals for the period, with exception for pertain fog. Restrictions were confined to ports nearest water sources. .OUTLOOK /WEDNESDAY THROUGH SATURDAY/... The next chance for restrictions will come with late week low pressure. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$ is the U.S. government's official web portal to all federal, state and local government web resources and services.
