Clouds Abound, Temperatures Up and Down
Jason Samenow @ 9:30 AM
For next several days, the metro area will be stuck in a battleground between cold air to the north and warm air to the south. These opposing airmasses will trade blows, resulting in a series of temperature swings (from mild to cool to mild to cool) as well clouds and intermittent rain showers.
Milder, chance of showers. We'll be on the warm side of the frontal boundary (just to our north) today, which should allow temperatures to finally surpass 50 degrees. The amount of sunshine will dictate how far above 50 it will get. I tend to think it will be mostly cloudy with occasional showers -- especially in the afternoon, preventing temps from reaching their potential (near 60). Nonetheless, it should still be 10 degrees warmer than yesterday, with highs 52-57. Overnight, skies remain cloudy with some spotty light rain a possibility, especially after midnight. Lows should be in the low to mid 40s.

Morning showers, a peek of PM sun? Cooler air will try to make a slight move southward with the frontal boundary dropping into the region by morning, but will retreat northward during the afternoon. There may be some lingering showers to start the day, followed by the possibility of some decrease in cloudiness and a bit of sunshine emerging. High temperatures should reach the mid to upper 50s. With a mild airmass in place overnight, low temperatures should only fall into the mid to upper 40s.
Mild again, chance of showers. While we'll begin the day on the warm side of the front, it's likely to gradually shift southward increasing shower chances as it passes by. Cool air will be slow to trickle in, with highs well into the 50s.
According to Wikipedia, only 7 tropical cyclones have formed in the Atlantic basin during December since 1944. Will we add an 8th? Just maybe. Last night, the National Hurricane Center (NHC) issued a Special Tropical Disturbance Statement pertaining to low pressure several hundred miles east of Puerto Rico. Says the NHC:

Tuesday
Morning showers, a peek of PM sun? Cooler air will try to make a slight move southward with the frontal boundary dropping into the region by morning, but will retreat northward during the afternoon. There may be some lingering showers to start the day, followed by the possibility of some decrease in cloudiness and a bit of sunshine emerging. High temperatures should reach the mid to upper 50s.

Mild again, chance of showers. While we'll begin the day on the warm side of the front, it's likely to gradually shift southward increasing shower chances as it passes by. Cool air will be slow to trickle in, with highs well into the 50s.A Look Ahead
- On Thursday, a strong cold front will move through the region in the evening, with showers likely most of the day. Highs should be in the low 50s.
- Skies clear on Friday with cooler air slowly filtering in, with highs near 50.
- We'll need to watch a storm developing to the south on Saturday. As it heads north, it should stay far enough east to bring just a few clouds, although precipitation (yes, that's intentionally vague) cannot be ruled out. Highs should be in the 40s.
- On Sunday, partly cloudy skies seem most likely, with highs again in the 40s.
