High pressure will be in control as we begin a new work week and it’ll drift to the east of here by mid-week. As a result, it’ll start off on the cool side, but turn milder on Tuesday. An influx of more Arctic air and its associated slow-moving cold front will have a big impact on a wide part of the nation this week and it’ll bring rain here at mid-week. Colder air will follow the frontal passage and we’ll see temperatures drop noticeably by the late week as Arctic air filters into the region.

Kind of a topsy-turvy temperature pattern this week with colder conditions today as cold, Canadian high pressure takes control and then milder conditions to return on Thursday. That warm up on Thursday will be short-lived, however, as another cold front swings through the Tennessee Valley and ushers in colder air for the late week and the start to the weekend. It turns milder again for the early part of next week with highs back to near the 50 degree mark.

A cold and active weather pattern will continue this last full week of January across the eastern US and there is growing potential for an important ocean storm early this weekend. Any impact in the Mid-Atlantic region would likely be in the Friday night/Saturday time frame and it will largely depend on the ultimate track of the storm and its intensification rate. Many ingredients are going to come together at the end of the week that will allow for explosive intensification of surface low pressure including the following: jet streaks in the northern and southern branches of the jet stream, plenty of cold air to the north and west, and deepening low pressure aloft that takes on a “negative” tilt. At this time, it is just too early to tell if this ocean storm will track well off the coast, close in or perhaps even ends up taking a slightly inland track which is a scenario that is still on the table though not too likely. It certainly looks like it’ll be an interesting next few days as we track this growing threat.

The week will start off milder (but close-to-normal) than recent days with high pressure over the northern Gulf of Mexico in control. As the high pushes to the east today, our low-level winds will become southerly pushing slightly milder air into the Tennessee Valley. Clouds will increase tonight as low pressure organizes near the northern Gulf and it can generate a couple of rain showers around here late tonight and on Tuesday. Sunshine should return on Wednesday as high pressure builds into the region from northwest of here, but it’ll turn colder with a low-level northerly wind flow.

The passage of an Arctic front on Thursday paved the way for cold cold air to push into the region and temperatures today will stay well below-normal for late January. Low pressure will move off the Carolina coastline later tonight and it will have no impact around here. The overall pattern remains cold through the weekend, but temperatures will modify on Monday likely able to reach the 50 degree mark for afternoon highs.

An Arctic air mass is filtering into the region today in the wake of the passage of a slow-moving frontal system. There is some post-frontal precipitation with this particular system and - with temperatures near the freezing mark – this can result in some freezing rain so watch out for slick spots on the roads. Winds will also be a factor today gusting up to 25 mph or so from a northerly direction as colder air filters into the region. It’ll remain on the colder-than-normal side into the upcoming weekend, but milder conditions are likely to arrive early next week.

An Arctic frontal system will work its way through the Mid-Atlantic region early tomorrow and some “post-frontal” snow can cause slick spots on the roads from about the time of the AM rush hour to around mid-day. Rain will break out later tonight in the DC-to-Philly-to-NYC corridor ahead of the Arctic front, but then as colder air filters into the region, precipitation will mix with and then change over to snow right around morning commute time on Thursday. Accumulations are likely to end up in the 1-3 inch range by mid-day tomorrow after the changeover takes place. Bitter cold conditions will follow the system for tomorrow night and Friday with overnight lows in the 10-15 degree range and highs doing no better than the 20’s to end the work week.
