Record Cold Arriving Tonight Wednesday Only Slow Moderation Late Week
Our arctic front is coming through today with a big yawn as far as precipitation is concerned. Rain that is on the radar this morning is in a narrow northeast southwest band and looks like a yardstick coming through. The cold air coming in from the west is impressive but the precipitation shuts off before it has any impact. While there could be a brief change over to some wet snow as the front passes offshore, it won’t amount to anything and it will not cause any issues regarding travel. By the time temperatures get below freezing, the precipitation is long gone and everything dries up. Temperatures will fall into the 30s this afternoon and then below freezing this evening as skies clear out. Gusty winds will bring wind chill into the equation but we are not looking at anything fierce as far as the wind goes.

Record lows are set for Wednesday morning with lows in the teens to lower 20s. Records for Wednesday are what I would call low hanging fruit as the numbers are not all that low. What might be more impressive will be records set for the “lowest high temperature” for the day Wednesday. Highs will only be in the upper 20s to mid 30s which is very cold for mid November. We will have plenty of sunshine but it will be ineffective sunshine.
Winds drop off and skies will be mainly clear Wednesday night which sets up for a very cold Thursday morning. Lows will be in teens in all but the warmest urban locations where it will be in the mid 20s.
We would moderate Thursday rather quickly were it not for the high going out to our northeast. This sets up a bit of an onshore flow. Clouds are likely to develop with only limited sunshine. Highs will be back into the 40s. Friday will be the bounce day as we head into the 50s before the next cold cold front approaches from the northwest and low pressure comes out of the Gulf of Mexico and moves to just off the Southeast US coast.
The upper air pattern is not favorable for this system to move up the coast but rather it gets kicked out to the northeast and well to our south. That allows high pressure from Canada to build into New England this weekend. This is going to keep things rather chilly around here. We also have to wonder about clouds with the onshore flow. This will be one of those instances where dry air from New England will try to drain southward but low clouds could be an issue this weekend and we have to decide whether there could be some spotty light rain or drizzle at some point, at least that could be the case for the immediate coast. Saturday is likely to be the better day with perhaps more sun but we may not get much out of the 30s to lower 40s for highs. We could be just in the 40s on Sunday.
