Forecast: Gorgeous, crisp fall weekend behind front

October 18, 2013/0 Comments/by John Homenuk

Warmer and unsettled weather which affected the area late this week is on the way out, being pushed away by a cold front which pushed through the region Thursday Night. The first in a series of expected cold fronts through late next week, cooler and less humid air will spill into the region by Friday afternoon. Luckily, along with the cooler air will come pleasant conditions with clearing skies and light westerly winds. This weekends weather will be characterized by plenty of sunshine, and temperatures topping out in the upper 60s. As it looks now, another gem on a long running list of great weekends which stretched back to September.

Cloudy, drizzly and unsettled through weeks end

The combination of a weak coastal system, meandering off the Mid Atlantic coast, and multiple mid level disturbances moving through the Northeast US will result in generally unpleasant weather from Wednesday through the end of the week. The coastal system is weak but brings moisture and an onshore flow, as the decaying mid level vorticity slowly retrogrades towards the coast on Wednesday. Low clouds and drizzle are possible, despite the lack of any steady rain, especially near the coasts.

Mid level disturbances shifting northeast from the Mississippi and Ohio Valleys through the Great Lakes and Northeast will bring more unsettled weather through the end of the week — signaling the beginnings of a more active pattern. The weekend is expected to feature improving conditions once the frontal system eventually moves off the coast.

Forecast: Unsettled, cooler pattern not far away

Despite the fact that pleasant weather has essentially dominated late summer and Autumn thus far, the pattern of late has trended a bit more unsettled. This is fairly typical for this time of year, as the first signs of wavelength changes are beginning to be seen in the atmospheric pattern and jet stream. However, a more dramatic pattern change is being forecast by most models in the medium range — with noticeable wave amplification throughout the Northern Hemisphere. In the short term, unsettled weather will begin to impact the area as early as Wednesday with a weak system meandering offshore beginning to back towards a coast slightly. Another frontal system back to our west will eventually approach and cross the area around mid-week, bringing in the first of several shots of cooler air.

Update: Cloudy and drizzly now, heavier rains tonight

After a brief bout of rain this morning, most of the area is currently in a dry-slot. Lots of dry air has filtered into the region thanks to a high pressure system to the north. And considering the storm is still well to the south of the area, there is not enough lift in the atmosphere at our latitude to consistently supply rain. This is why our forecast called for the heaviest rain to be tonight and tomorrow morning, rather than today.
