&& .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... Minimal day-to-day change expected through the period as the forecast area remains parked under a eastern CONUS ridge. Temperatures will be 10 to 15 degrees above seasonal levels with dewpoints in the low to mid 60s. Diurnal chances for showers/storms can be expected each day with daytime heating but there does not appear to be any significant features to focus activity until late on Sunday. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... The eastern CONUS ridge is progged by ensemble guidance to shift east off the coast by early next week. Mainly diurnal shower and thunderstorm chances are expected in the moist, unstable atmosphere west of the ridge through much of the long term period. Models differ on the handling of a low across the Carolinas by mid week, and the northern extent of any associated precip. Used adjusted Superblend guidance through the period to account for the uncertainty and varying operation model solutions. Temperatures are expected to remain above seasonal levels. && .AVIATION /01Z FRIDAY THROUGH TUESDAY/... VFR conditions will persist through the evening hours. Towards morning, increasingly moist low levels will allow for MVFR fog formation at most terminals, with some IFR ceiling possible at FKL/DUJ. A weak wave may provide a few overnight showers but chances are too low for inclusion. VFR will be reestablished by midmorning Friday as fog dissipates and ceilings lift. An isolated shower or storm remains possible Friday afternoon, but again, not enough confidence in ocurrence for a VCSH/VCTS mention at this time. CL .OUTLOOK /FRIDAY THROUGH MONDAY/... Restriction chances in afternoon/evening convection will continue through the holiday weekend. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && $$
