A frigid start this morning followed by an even colder morning coming up tomorrow.
High pressure is in full control of New England this morning and this will remain the case through the day tomorrow. Temperatures this morning could have gotten colder, but there was enough of a breeze to keep the air mixed and temperatures up slightly. The same wind is resulting in below zero wind chills however. Daytime highs will be in the teens and low 20s and with the wind, wind chills values will remain very cold. Be careful if you are going to be outdoors for an extended period of time today.
The winds will die down tonight, this combined with the same cold air mass overhead will cause temperatures to plummet tonight. Looking at some of the temperature guidance for tomorrow morning, it looks like some spots will fall way, way below zero. This will likely happen in the typical cold spots of Northern and Central New England, especially in valleys. For example, the low temperature forecast for Berlin, NH is -30 for Friday morning. Needless to say, be prepared for a very cold start. We will have another day of sunshine, for the most part, a few clouds will likely move in throughout the day. Temperatures will climb to the upper 20s and low 30s in the afternoon.
The warm air will really start moving in on Friday night, starting above our heads and then at the surface during the day on Saturday. The milder conditions are being forced in by a large area of low pressure that is currently developing in the Central United States. As this system gets more organized, it will tap into moisture from the Gulf of Mexico. This will make this system very "wet" and will likely result in flooding for some locations east of the Mississippi River. We should stay dry here in New England until Sunday as the system will be moving very slowly. All the precipitation will be elongated along the low pressure system's cold front that will drape from the center of the low down toward the Gulf Coast. Eventually the low will pass through the Great Lakes and then well off to our north and west. This will keep the Northeastern US on the warm side of the storm and provide rain for almost everyone.
Temperatures will shoot up nicely on Saturday, reaching at least the 40s with a few 50s in Southern New England. Look it to be a few degrees warmer on Sunday than Saturday, with rain moving in during the afternoon. The model runs from last night and this morning aren't showing as much rain as they were yesterday morning and then ones that weren't showing a lot of rain, now are. I still expect a good deal of precipitation to fall here in New England, which will more than likely result in some flooding problems, especially when you combine it with the warmth we will have.
Stay tuned! Thanks for reading!
