High pressure will maintain dry and warm weather most of today. Unsettled but warm weather is expected for the second half of the week.
-- End Changed Discussion --
&& .NEAR TERM /UNTIL 6 PM THIS EVENING/...
-- Changed Discussion --
Ridging should maintain dry weather most of today. Slight to low chances for showers and thunderstorms should return toward evening for areas west of the PA/OH border as a weak shortwave approaches. Temperatures are expected to average around 10 degrees above seasonal levels.
-- End Changed Discussion --
&& .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/...
-- Changed Discussion --
The weak shortwave is progged to complete it`s passage across the region tonight, with shower chances continuing. A few early evening thunderstorms are possible with marginal instability across Ohio. Another weak crossing shortwave Thursday should maintain shower and thunderstorm chances across the area. Moisture and instability should continue to increase in southwest flow through Saturday on the western periphery of an eastern CONUS ridge. With a lack of significant shortwave support, expect mainly diurnally driven showers and thunderstorms. The warming trend should continue, with temperatures 10 to 15 degrees above seasonal levels expected using the latest GFS MOS and consensus guidance.

&& .LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
-- Changed Discussion --
Ensemble progs indicate the east coast ridging should persist through early next week. A relatively moist and unstable airmass in place should result in daily, mainly diurnally driven shower and thunderstorm chances through the period. Temperatures should continue averaging 10 to 15 degrees above seasonal levels. Used edited Superblend guidance for the long term period to account for uncertainty and to smooth out day to day operational model differences.

&& .AVIATION /07Z WEDNESDAY THROUGH SUNDAY/... VFR can be expected through Wednesday. There is a chance for degradation at zzv this eve as a disturbance supports scattered showers and possibly a thunderstorm. Have addressed this with a "vicinity shower" mention given a lack of confidence in convection coverage. .OUTLOOK /THURSDAY THROUGH SUNDAY/... Restriction chances in scattered showers and possible thunderstorms will continue into the weekend. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$ 07/15
