High pressure is going to be the “driving force” behind our weather today. Things are much calmer early this morning, since yesterday’s early wind managed to subside, as anticipated. Temperatures should reach the mid 50s this afternoon, and then will wind up mostly in the 30s tonight. Whether or not the typically colder spots well inland wind up in the mid or upper 20s will depend largely on cloud cover. We can’t forget that there’ll be a cold front moving across the Northeast tonight and early tomorrow, which may bring a few clouds to the greater Baltimore area, but nothing more. We still believe that temperatures in most places will be hard-pressed to get out of the 40s tomorrow, but this is obviously normal for early in December.
There are no changes in the thinking about the weekend forecast, with both tomorrow and Sunday featuring a good deal of sunshine — the return flow on the back side of the high pressure system as it drifts out into the Atlantic will usher in some milder air, and temperatures will be back in the 50s on Sunday, and probably in the lower 60s Monday and Tuesday. The longer range forecast still hinges upon the eventual timing of our next round of rain, and the eventual change to colder and drier air that will follow on its heels. Although we’re still mentioning the possibility of rain as early as Monday night, the global models still seem to push the next front along “slowly enough” that the greatest rain chances along the Eastern Seaboard will actually be later on Tuesday, Tuesday night and Wednesday.
