In the wake of yesterday’s storm system, the week will close out on a cold, but dry note with afternoon highs confined to the middle 40’s. The normal high for this time of year is about 57 degrees so we’ll be well below as we head into the weekend. High pressure will settle in this weekend and a warming trend will begin across the Tennessee Valley. In fact, the 60’s are likely for highs around here by the early part of next week, but the warm up on Monday and Tuesday will also come with a chance of showers. It’ll turn colder again for the second half of next week following a mid-week cold frontal passage.

Colder air has moved into the region and a large batch of moisture will head northeast today resulting in some rain around here and it might become just cold enough for a transition to snow and/or ice later today across northeast Alabama and southern middle Tennessee. In these colder areas, small accuumulations are even possible by early tonight. A clearing trend will develop late tonight as a large scale upper-level trough slides to the east of here and a reinforcing Arctic air mass will push in resulting in quite a cold finish to the work week and also to the beginning of the upcoming weekend. High pressure will settle in later in the weekend and a warming trend will begin. In fact, the lower 60’s are likely for highs around here by the early part of next week, but the warm up on Monday and Tuesday will also come with a chance of rain showers.

It has turned colder today across the Mid-Atlantic region and an even colder air mass will push in for tomorrow and Friday. At the same time, a large batch of moisture will push northeastward on Thursday and the combination of the fresh, cold air and moisture should lead to a significant snow event from southern Virginia-to-North Carolina-to-upstate South Carolina. As has been the case for much of the winter season, the corridor from DC-to-Philly-to-NYC will very likely escape without any appreciable snowfall, but there are some signs for more sustained cold and perhaps a better chance for snow as February winds down and March gets underway.

A cold front has passed through the region bringing cooler air to the region and it’ll turn even colder on Thursday. It’ll stay quite unsettled as well with a chance of rain showers today and tonight and then a chance of rain and/or snow showers for tomorrow and tomorrow night. Dry and chilly weather conditions are likely for the end of the work week and then a warm up will take place this weekend and into the early part of next week.

It goes without saying that this winter has been very frustrating for snow lovers in the DC-to-Philly-to-NYC corridor as there just hasn’t been the right combination of cold and moisture to result in significant snowfall. A strong cold frontal passage at mid-week will indeed usher in a cold air mass fully capable of producing snow in the Mid-Atlantic region as long as moisture becomes available. In fact, there will be plenty of moisture meandering across the southern US over the next couple of days and it looks like some of this will northeastward into the Carolinas and as far north as southern Virginia at the same time this upcoming cold air mass becomes firmly established. The result may be a significant snow event from southern Virginia to upstate South Carolina with half a foot possible in North Carolina and – as has been the case for much of the winter – snow lovers from DC-to-Philly-to-NYC will be looking with envy from the outside. Longer term, there are some signs of hope for cold and snow in the Mid-Atlantic’s I-95 corridor, but we have had false promises already this winter and time is beginning to run short.

High pressure has shifted to the Mid-Atlantic region as we begin the new work week and this will result in warmer conditions across the Tennessee Valley. In addition to the warm up, it has turned more humid as Gulf of Mexico moisture pushed northward on the back side of the high pressure system and this will increase our chances for showers and thunderstorms. A cold front will drive through the region by later tonight bringing colder air into the region for the second half of the week. A lot of moisture will be hanging around the Gulf States and SE US later this week and this could result in some rain and/or snow activity around here.

High pressure will shift to the Mid-Atlantic region as we begin the new work week and this will result in warmer conditions in the Tennessee Valley. In addition to the warm up, it’ll turn more humid as Gulf of Mexico moisture pushes northward on the back side of the high pressure system. By tonight and Tuesday, we’ll come under the influence of a cold frontal system that will be dropping southeastward from the Northern Plains. The chance of showers will increase around here tonight and continue on Tuesday before colder, drier air moves in at mid-week.

After a cold start to the day, sunshine will boost temperatures into the 40’s for the afternoon to go along with dry conditions. It’ll stay dry into the weekend with high pressure taking control and a warming trend will bring us back to 60+ degrees by early next week.

An Arctic front has pushed through the Northern Plains and into the Upper Midwest at mid-day and temperatures have plunged to below zero in many locations. In addition, winds are quite strong in these same areas resulting in dangerous wind chill values as low as 30 degrees below zero. This Arctic air outbreak will continue to push to the south and east over the next 24 hours and will bring some of the coldest readings yet this season to the Mid-Atlantic and Northeast US by the early part of the weekend. As has been the case for much of the winter, the cold air will be rather short-lived and temperatures will ease noticeably by Sunday afternoon in the Mid-Atlantic/NE US.

A cold frontal system has cleared the region in the overnight hours and temperatures will turn out much cooler today compared to yesterday as clouds thin out. Favorable conditions for radiational cooling will take place tonight (i.e., clear skies, light winds) and overnight lows will likely be in the middle 20’s. It’ll stay dry into the weekend with high pressure taking control and a warming trend will bring us back to 60+ degrees by early next week.
