4/11/12 Summer comes back for the weekend!

A stubborn area of cold low pressure over Canada will bring more of an influence to our weather today and tomorrow as it slowly begins to move south and east and eventually out to sea late on Thursday.

The cold air continues to filter in as it rotates around the low pressure.
The air aloft is quite cold at around 5,000 feet. (Well below freezing). Higher elevations today may see a snow flake or some ice pellets in the pop up showers that form. Interestingly, the highest elevations in New England have seen close to TWO FEET of snow!

With situations where you cook the surface of the Earth with sunshine and you have extremely cold air just above the surface you get an excellent chance for rising air and a wide array of pop up showers to form. These showers will be quite random across the northeast. There will not be much in the way of lifting to produce thunderstorms, but enough cold air could help produce some ice pellets to drop from the sky or a snowflake or two.

The low moves out to sea by Thursday night and is replaced by high pressure that will set up off of the Carolinas. This will help bring sunshine and usher in a warm southwest wind for the weekend.  Expect highs to reach into the 70s for the weekend, with an 80 possible on Sunday. However, clouds and a late day shower or thunderstorm may keep temperatures slightly cooler than what they could be.

Weekend weather pattern shows warm air surging into the northeast. A cold front and area of low pressure over Lake Superior will move close to the Northeast by later Sunday.
Today's (SLEET) accounts for some ice pellets that may fall in a few showers especially across the higher terrain. Sun returns for Friday and Saturday. An 80 is possible on Sunday, depending on the timing of the cloud arrival.
