This morning I’m looking at an overwhelming amount of data pointing to a returning cold pattern that frankly, I’ve had a hard time piecing together exactly what I’m seeing and what it means for the northern Mid Atlantic and the East coast as a whole. The implications of the developments at the stratospheric [...]

For the first time in a while, I can actually say there is no threat of rain of any kind through this weekend, and frankly that’s nice to say. High pressure will dominate the northern Mid Atlantic through Monday with dry conditions, clear skies, and temperatures rebounding to near and above normal temperature regimes!

First, for those new to NY NJ [...]

The upper low that had dominated the weather conditions over the Plains and Mississippi Valley for several days has been ejected to the east and is rapidly weakening.
The remnant short wave trough over the Ohio Valley is still pulling a great deal of moisture to the north into the Southeast, Mid Atlantic, and Northeast. [...]

I think most would agree that the Labor Day weekend has been the best weather weekend of the summer, which is ironic since this weekend is the last of the “summer” weekends for those in the vacation business. The air mass will be shift to a more humid pattern once again and with higher [...]

The end of the week is expected to be rather quiet, but rather chilly for the middle of March. A strong cold front will exit the forecast area on Wednesday night with strong Canadian high pressure building into the region from the northern Plains. At 500 MB, a strong upper low located at 50 [...]
