Discussion

A strong cold front has passed through the region ushering in much cooler air for today and the weekend, and weather conditions will remain quite unsettled as a coastal low pressure system forms along the now stalled out front. Showers will linger around here into Saturday as a slow-moving nor’easter strengthens along the frontal boundary zone over the next 24 hours or so and it'll remain quite windy and cool. In fact, the air will actually be cold enough farther north for some snow to fall from this coastal low in the interior higher elevations of the Northeast US. Strong Canadian high pressure will take better control of our weather on Sunday and Monday with plenty of sunshine expected both days, but it’ll still be rather cool for this time of year. Milder air works its way to the Mid-Atlantic region by the middle of next week with the 80's likely again later next week.

Below normal temperatures are likely for the upcoming holiday weekend as marine flow of air continues the pattern of late night and early morning low clouds and fog along coastal locations. Some slight warming is possible by the latter part of next week as offshore winds may re-develop.

Discussion

Big changes are on the way for the Mid-Atlantic region over the next couple of days as the pattern transitions from summer-like to rather winter-like by early this weekend with a full-fledged nor'easter developing off the Northeast US coastline. The transition from summer's warmth and humidity to yet another chilly air mass has actually already begun as the peak in the heat occurred yesterday with highs in the upper 80's in many parts of the DC metro region. Temperatures will actually drop more than 40 degrees over the next couple of days from yesterday's highs in the upper 80's to weekend lows in the middle 40's. As a powerhouse cold frontal system approaches the east coast today, there will be occasional showers and thunderstorms. Any shower can contain heavy rainfall and any thunderstorm that forms this afternoon and evening can reach strong-to-severe levels with heavy rain, strong gusty winds and hail. In fact, there will likely be scattered strong-to-severe thunderstorms up and down the east coast later today from the Carolinas to New England as this strong cold front heads to the coast.

Once the cold front reaches the east coast later tonight, a strong upper level low will dig into the Mid-Atlantic coastal region, and this will to cause the frontal system to grind to a halt as a nor’easter-type of coastal storm develops at the same time much chillier air pours into the region. As a result, Friday will turn out to be breezy and much cooler than today in the Mid-Atlantic region with lots of clouds and residual showers and, as the coastal storm only slowly pulls away to the northeast, Saturday will likely also turn out to be somewhat unsettled with some clouds, breezy and cool conditions with a lingering shower or two possible; especially, in areas to the north and east of the District. Farther north, the colder air mass will actually allow for the possibility for snowflakes to fall in some of the interior, higher elevation (>2000 feet) locations of the Mid-Atlantic and Northeast US early this weekend (e.g., Adirondacks, Green and White mountains). By Sunday, strong Canadian high pressure should finally take control of the weather and there will be plenty of sunshine around and that pattern will continue on Monday as well, however, both days will remain cooler-than-normal (normal high is now 77 degrees).

An upper level ridge will take control of our weather as we approach the end of the work week and this will set us up for a nice holiday weekend. In fact, the weather forecast for Friday through Memorial Day can be basically summed up with “mostly sunny and warm with highs near 80 degrees” each day in that period of time.
