Sterling nibbling:
.LONG TERM /FRIDAY THROUGH TUESDAY/...
Split upper level flow will persist Friday over the central and
eastern U.S. There remains the potential for some wintry
precipitation over parts of the region late in the weekend, which
will ultimately be determined by the interaction of the northern and
southern stream. At the surface, high pressure will reside over the
southeast U.S. on Friday with a Saskatchewan Screamer (Alberta
Clipper) moving over the northern Great Lakes. This system will
progress eastward on Saturday, with a cold front passing through the
local region likely sometime Saturday. Highs ahead of this cold
front could approach the upper 50s to near 60 degrees east of I-81.
Temperatures will remain closer to normal (or slightly below) Sunday
heading into early next week as an upper level trough moves
overhead.
Regarding precipitation potential, ensemble probabilities and the
NBM indicate snow is possible across the region, with higher
probabilities along the Allegheny Front Saturday night
except in wedgie areas
