Discussion
It’ll turn milder today after a cold, damp start to the day and afternoon temperatures should make it to the upper 40's for highs. A strong cold front will sweep through the region later this evening and likely bring us a round of rain showers before midnight. As low pressure intensifies over New England on Wednesday and strong high pressure edges this way from the Upper Midwest, the pressure gradient will tighten and winds will pick up dramatically. In fact, winds could gust to 45 mph on Wednesday and they’ll stay strong through Thursday to go along with progressively colder temperatures. Looking ahead to the weekend, snow is a threat around here as low pressure pulls out of the Gulf of Mexico at the same time strong, cold high pressure slides eastward across southern Canada. It is still too early to tell how quickly this Gulf storm can intensify by the time it reaches the Mid-Atlantic coastline as that'll depend on potential phasing of a northern stream wave of energy with a southern stream disturbance…stay tuned.
