The country is sharply divided today in terms of temperatures with record-breaking warmth in the East and bitter cold in much of the western half of the nation. In addition to the cold, accumulating snow is falling in a swath from the Upper Midwest to northern New England from a storm system that has impacted a large part of the nation in recent days. Snow is also falling across many western states and blizzard warnings have been posted in of all places the southern part of California. In fact, for the first time ever, blizzard warnings have been issued by the San Diego office of NOAA’s National Weather Service for the San Bernardino Mountains.

The passage of a warm front will result in a dramatic temperature surge around here this afternoon with afternoon highs likely to be close to the 80 degree mark…perhaps even a record-breaker. A cold front pushes through later tonight and it will result in windy and noticeably cooler conditions for the end of the work week. It remains quite chilly on Saturday and weak low pressure can produce some snow and/or rain shower activity in the region, but its moisture content will be rather limited. Another system could bring us some additional precipitation during the early part of next week.

A cold front pushed through the region late yesterday and today will turn out to be cooler with mainly cloudy skies. Rain is likely by later in the morning or early this afternoon as low pressure pushes to our northwest and a warm front approaches from our southwest. Following the passage of a warm front, temperatures should jump dramatically on Thursday - well up into the 70’s - with partly sunny skies and breezy conditions. Another cold front passes through the region tomorrow night ushering in colder and very windy conditions for Thursday night and Friday. Low pressure could produce some snow shower activity around here on Saturday, but the moisture content for this system appears to be limited.

Low pressure will track northwest of the region today producing a few showers; primarily, in the afternoon hours. In addition, the winds will pick up noticeably this afternoon with gusts possible to 45 mph. It’ll turn colder later tonight on the heels of a cold frontal passage and skies will clear after midnight. On Wednesday, it’ll be a colder day and there will be the chance of rain as a warm front approaches from our southwest. After the passage of the warm front, temperatures could shoot up well up into the 70’s on Thursday - perhaps record-breaking territory - and then another cold shot will arrive at week’s end. Low pressure could produce some rain and/or snow shower activity around here sometime during the upcoming weekend.

The overall weather pattern across the eastern US has been active in recent weeks and there is reason to believe it’ll remain quite energetic over the next couple of weeks. In fact, the Mid-Atlantic/Northeast US can become quite a “battle zone” region with the development in coming days of high-latitude blocking across Greenland/Northeastern Canada at the same time high pressure ridging persists over the Southeast US. There will be times when the SE US ridge shows its strength with warm air surging northward into the Mid-Atlantic region and other times in which the high-latitude blocking flexes its muscle resulting in cold air dropping southward from Canada into the northeastern part of the US.

The week ahead will feature and up and down temperature pattern and it’ll be unsettled with a series of low pressure systems moving by to our northwest. Today will be a mild day and there can be some shower activity this afternoon with the approach of a cold frontal system, but rain is more likely later in the evening. It stays mild on Tuesday with a shower threat and then colder on Wednesday. The warmest day of the week is likely to be on Thursday before colder air returns for the end of the week.

A strong cold front will pass through the region this morning ushering in a cold air mass for tonight and Saturday. Winds ahead of the front this morning will be from the southwest and then will shift to a northwesterly direction in the afternoon and temperatures will fall into the 40’s. Temperatures late tonight will bottom out in the mid-to-upper 20’s and be confined to the mid 40’s for highs on Saturday afternoon. Temperatures will rebound on Sunday and Monday as high pressure shifts to a position off the east coast allowing for the formation of a low-level southwesterly (and milder) flow of air.

A warm front will result in some shower activity around here later today and temperatures will again reach unseasonably mild levels likely in the upper 60’s for afternoon highs. A cold front will head this way later tonight bringing with it additional showers lasting right into the morning hours on Friday. It’ll turn much colder on Friday night and Saturday, but this cold snap will be rather short-lived as temperatures should rebound noticeably for Sunday and Monday.

The next couple of days will be unseasonably mild in the Mid-Atlantic region with upper 60’s on the table in the DC metro region for afternoon highs. As a front approaches on Thursday, the chance for showers will be on the increase and winds will pick up in intensity as well. After the frontal passage on Friday, it’ll turn much colder for Friday night and Saturday, but - as has been the case with most recent cold snaps - this one will be rather short-lived. Temperatures will begin a noticeable rebound on Sunday and the milder pattern will continue early next week.

A weak cool front passed through the region last night and high pressure will now resume control of the weather in the Mid-Atlantic region. After a mild day on Tuesday, it’ll turn even warmer tomorrow and it stays relatively warm on Thursday as well. Showers are likely later in the week as the next cold front approaches the eastern states from the Ohio Valley. Following the passage of this next cold front, it’ll turn colder to begin the weekend, but - as has been the case in recent weeks - the cold snap will be rather short-lived.
