Forecast for Monday, November 19, 2012

A northeasterly flow has developed across the region and this has been resulting in a lot of high clouds, especially across the eastern half of the region. A lot of these clouds should linger into the overnight hours. They may break up a bit early in the morning on Monday…but they should soon redevelop with some daytime heating. The clouds are expected to insulate most of us tonight preventing a rapid drop in temperature. However, there may be enough drier air north and west of the city to keep the clouds thin enough so that the temperatures drop off a bit more there.  These same clouds should prevent our area from warming up aggressively on Monday.

An area of high pressure looks as if it will block an area of developing low pressure from moving close to the coastline Tuesday and Wednesday. With this low expected to track well south and east, only some clouds and an increasing breeze are expected Tuesday and Wednesday. A few widely scattered sprinkles or rain showers cannot be ruled out along the coast Tuesday Night or Wednesday, but even here there should not be much in the way of measurable precipitation.

A cold front is expected to sweep across the region Friday Night into Saturday Morning with a low pressure area riding to our north. The cold front should bring some scattered rain showers as it passes through and there will be some chilly air moving in behind it. There could be some snow flurries or even a snow shower Saturday Night and Sunday, especially in the Poconos and Lehigh Valley. It will turn breezy behind the frontal passage.
