... Canadian high pressure will build from the Great Lakes into the Northeast and Middle Atlantic through today, then gradually shift offshore during the first half of next week.
NEAR TERM /THROUGH TONIGHT/... High pressure will remain in control through tonight. Plenty of sunshine today will be followed by mainly clear skies tonight. Temperatures will be below average once again through the period. Highs will reach the middle 60s. Lows will drop into the lower 40s. Patches of frost is possible again later tonight along and west of the Blue Ridge.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Plenty of sunshine and cooler than normal temperatures expected once again Monday through Tuesday night. High pressure will remain overhead. Highs Monday will reach the middle 60s once again, while highs on Tuesday could reach near 70.
LONG TERM /WEDNESDAY THROUGH SATURDAY/... Warmer weather will prevail through the long term as surface high pressure shifts to our south and ridging briefly builds in overhead. This will allow warmer west to southwest winds to envelop the region, with temps returning to near to just above normal with temps rising to the upper 70s to near 80 during the afternoons, dropping to the 50s by the late night periods.
It is notable that some guidance suggests that the remnants of Beta could try to bring clouds and rain into the region by the end of the week into next weekend, but confidence on this solution remains very low, and a passing front/upper level trough may end up supressing it to our south.
