A cold frontal system dropped through the region early yesterday and it ushered in a colder air mass that will stick around right through the upcoming weekend. In addition to the chill, winds will continue to a factor from the northwest causing it to feel even colder than the actual ambient air temperature. This colder air mass is anchored by strong high pressure across southern Canada which will remain in control through Sunday at which time it’ll begin to shift eastward. Looking ahead, once this high pressure system shifts to the western Atlantic Ocean early next week, a big warm up will develop in the eastern half of the nation. This warm up will first develop across the central US and then it'll expand into the eastern US. Much warmer conditions will arrive here in the Mid-Atlantic region for the Tuesday/Wednesday/Thursday time frame with highs likely well up in the 60's by the middle of next week.

A strong and cold Canadian high pressure system will dominate the weather scene over the next few days in much of the northeastern quadrant of the nation including the Mid-Atlantic region. The days will feature colder-than-normal temperatures for early March and persistent NW winds will make it feel even colder than the actual ambient air temperature. Once this high pressure system shifts off the east coast early next week, a strong southwesterly flow of air will set up on its backside and begin a significant warm up in the central US on Sunday/Monday which will then expand into the eastern states on Tuesday/Wednesday/Thursday.

A cold frontal system dropped through the region last night and has ushered in a colder air mass that will stick around right through the weekend. In addition to the noticeable cool down from yesterday, winds will become a big factor later today and we'll have stiff NW winds into the early part of the weekend. This colder air mass is anchored by strong high pressure across southern Canada which will remain in control through Sunday. Looking ahead, once this high pressure system shifts to the western Atlantic Ocean early next week, a big warm up will develop - first across the central US and then it'll expand into the eastern US. Much warmer conditions will arrive here for the Tuesday/Wednesday/Thursday time frame with highs likely well up in the 60's by the middle of next week.

High pressure will build into the southern Mid-Atlantic region today and the result here will be a noticeable improvement in temperatures and much less wind compared to the past 36 hours or so. A cold frontal system will drop southward through the region tonight and it’ll usher in a colder air mass for the remainder of the week and for the upcoming weekend. This colder air mass will be anchored by strong high pressure across southern Canada and this system will be in control from tomorrow through Sunday.

The rain that we have experienced since early yesterday will wind down this morning and an Arctic front will blast through the region late in the day. As a result, winds will kick up noticeably later today and they will be very strong tonight with gusts possible to 50 mph or so. In addition, temperatures will drop sharply in the overnight hours bottoming out in the mid-to-upper 20’s and wind chills will be considerably lower. After a cold and sunny day on Tuesday, temperatures will moderate at mid-week under continuing mostly sunny skies.

Don’t be surprised to see some snowflakes later tonight in some of the northern and western suburbs along the DC-to-Philly-to-NYC corridor as moisture pushes into a relatively cold and dry air mass (dew points in the teens). In fact, there can be a coating to an inch or so in some of the nearby northern and western suburbs of Philly and NYC and also in some of the far northern and western suburbs of DC.
Rain will be the dominate precipitation type on Saturday morning in the DC-to-Philly-to-NYC corridor before it winds down at mid-day and there will be significant rainfall on Sunday and Sunday night. An Arctic front will then blast through the Northeast US/Mid-Atlantic region on Monday and the winds will kick up noticeably later in the day and continue quite strong on Monday night. In addition, the plunge in temperatures will be quite dramatic in this short, but intense Arctic cold air outbreak and there can even be a few snow squalls in the Northeast US upon its arrival.

This system can generate some rain by later tonight and the rain will continue on Saturday morning. A more significant rainfall is coming to the DC metro region for Sunday and Sunday night. A cold front pushes through the area early Monday bringing in another chilly air mass for the early part of next week and the winds will kick up noticeably by late in the day.

High pressure will take control today and under mostly sunny skies, afternoon temperatures will climb to the much more comfortable low-to-mid 60's - likely the warmest day since Christmas Eve (62 degree high). A cold front passes through the region tonight perhaps accompanied by a shower or two and it’ll turn colder again for the last couple days of the work week. By the end of the week, low pressure will try to form near the Mid-Atlantic coastline and it can produce some rain in the area on Friday night and Saturday - perhaps mixed with snow for a brief time.
