Following a frontal passage, high pressure will build into the region today and funnel in colder air with a northwesterly wind. This same high pressure system will shift to the east of here by mid-week allowing for a southwesterly flow of air to boost temperatures to milder levels.

The week will start off with far below-normal temperatures in the Mid-Atlantic region following the passage of a strong cold front on Sunday night. Temperatures will struggle today to climb past the freezing mark and overnight lows should be in the lower teens in most areas...coldest readings so far this season. Some moderation in temperatures will come by the middle of the week as a low pressure system passes by to our north, and then a “clipper” system could produce some snow and/or rain around here later in the week. Looking ahead, another frigid air mass is likely to impact much of the central and eastern US this weekend supported by an extremely strong Canadian high pressure system.

Low pressure will slide by to our south today and produce accumulating snow across much of central and southern Virginia. In fact, some of the snow can make it as far north as the DC metro region; especially, into those areas on the south and west sides of DC so watch out for possible slick spots and small accumulations later this morning. The week will start off with far below-normal temperatures following the passage of a strong cold front on Sunday night and temperatures later tonight will drop to their lowest levels so far this season. Some moderation in temperatures will come by the middle of the week as a low pressure system passes by to our north, and then a “clipper” system could produce some snow and/or rain around here later in the week.

The weather on Oahu, Hawaii in the early morning hours of Sunday, December 7th, 1941 was not at all unusual for the time of year with mild temperatures and mainly clear skies. Unfortunately, the weather conditions on that particular day would play a role in the bombing of the U.S. naval base by Japanese fighter planes at Pearl Harbor near Honolulu, Hawaii. As Japanese fighters crossed the Pacific Ocean, they were given hope that their mission would succeed when the announcement was made of “clouds mostly over the mounts…visibility good”. It is believed that the decision to attack on that particular day had plenty to do with the projected favorable weather conditions.

Low pressure is pushing to the northeast today from the southeastern states and its moisture field is moving into some very cold and dry Arctic air across the Mid-Atlantic region. The result is that snow has broken out across the southern Mid-Atlantic region and accumulations are likely in the region from DC/Virginia to the Delmarva Peninsula to southern New Jersey. In fact, the DC metro region can see as much as 2 or 3 inches of snow and as much as 4 or 5 inches can accumulate in sections of central and southern Virginia. The Philly and NYC metro regions will be on the northern fringe of this system with light snow a possibility and perhaps a coating in some areas.

Low pressure is pushing to the northeast today and its moisture field is moving into some very cold and dry Arctic air across the Mid-Atlantic region. The result is that snow has broken out across the southern Mid-Atlantic region and accumulations of as much as 2 or 3 inches are possible today in parts of the DC metro region. The steadiest snow should wind down by mid-day and then snow showers are possible in the afternoon and there can be a bit of freezing drizzle. In areas just to the south of us, as much as 4 or 5 inches can accumulate today across central and southern Virginia. Following today’s system, the bulk of the weekend should turn out to be mainly dry and moderately cold with some sunshine likely on both days. By Sunday night, another strong cold front and its associated “clipper” low pressure system can bring some rain and/or snow shower activity to the metro region.

An Arctic blast that resulted in numerous record low temperatures this morning across the Upper Midwest/Great Lakes is on its way to the Mid-Atlantic region, and it will set the stage for an accumulating snow event on Friday in the southern half of the area from DC/Virginia to the Delmarva Peninsula to the southern part of New Jersey. Temperatures in the overnight hours will drop into the teens in many of the suburbs along the I-95 corridor following the passage of an Arctic cold frontal system later today. Moisture on Friday will spread to the northeast from the Tennessee Valley and run into this very cold and dry Arctic air mass and snow will break out early in the day across much of Virginia and the DC metro region...in other words, both the AM and PM commutes can be slippery in these areas on Friday.
