The interesting and active weather pattern of recent weeks will continue into at least the middle of the month with two storms on the table for this week in the Mid-Atlantic/Northeast. The first storm for the Mid-Atlantic/Northeast US will come on Monday and an even bigger threat comes at mid-week with the greatest potential impact. In fact, the mid-week storm could turn out to be a major snowstorm for a large part of the Mid-Atlantic/Northeast US. In the short term, the weather remains mild during the next couple of days in much of the eastern half of the nation, but a colder air mass is going to filter into the northeastern quadrant of the nation on Sunday night and Monday following the passage of a cold front - setting the stage for a very wintry week.

The interesting and active weather pattern of recent weeks will continue into at least the middle of the month with two storm threats on the table for next week in the central and eastern US. The first storm threat for the Mid-Atlantic/Northeast US will come during the early part of next week and an even bigger threat comes at mid-week with the greatest potential impact. In fact, the mid-week storm could turn out to be a major snowstorm for a large part of the Mid-Atlantic/Northeast US. In the short term, the weather turns milder in much of the eastern half of the nation, but a colder air mass is going to filter into the northeastern quadrant during the early part of next week following the late weekend (uneventful) passage of a cold front.
Teleconnection indices such as the Arctic Oscillation (AO) and North Atlantic Oscillation (NAO) are supporting the idea of “high-latitude blocking” to get well-established by the middle of next week which, in turn, supports the idea for strong high pressure to build across southeastern Canada – always a key factor to the prospects of getting accumulating snowfall in the I-95 corridor. In this time period, two separate waves of energy will cross the southern states and then move northeastward towards the Mid-Atlantic coastline. With a cold air source building to the north across the southeastern part of Canada by the middle of next week, this type of setup could result in significant accumulating snow for at least parts of the Mid-Atlantic/Northeast US.

High pressure has taken control of our weather and will result in milder conditions around here as we head into the weekend. Low-level winds will shift to a southerly direction today as the high shifts off the eastern seaboard and we’ll stay mild on both weekend days just ahead of the next cold frontal system. The weekend cold frontal passage will be accompanied by a few showers and then a colder air mass will build into the region early next week. The overall weather pattern will remain very active next week with two storm threats to monitor - one on Monday and the second on Wednesday - and enough cold air will be around to allow for the possibility of snow getting involved especially at mid-week.

The interesting and active weather pattern of recent weeks will continue into at least the middle of the month with multiple storm threats on the table for next week in the central and eastern US. The first storm threat for the Mid-Atlantic/Northeast US will come during the early part of next week and perhaps the bigger threat comes at mid-week. The weather turns milder over the next few days in much of the eastern half of the nation, but a colder air mass is likely to arrive in the northeastern quadrant during the early part of next week following the late weekend passage of a cold front. Teleconnection indices such as the Arctic Oscillation (AO) and North Atlantic Oscillation (NAO) are supporting the idea of “high-latitude blocking” to get established by the middle of next week which, in turn, supports the idea for high pressure to build across southeastern Canada.

High pressure will take control of the weather around here for the next couple of days and a warming trend will begin and continue right into the upcoming weekend. The next cold front will approach during the second half of the weekend likely accompanied by some rain shower activity in the Mid-Atlantic region. A colder air mass arrives here on Monday after the passage of the cold front and we’ll have to watch for the possibility of low pressure forming near the east coast by the middle of next week.

A cold front is approaching the Mid-Atlantic region and it is accompanied by a strong wave of energy in the upper part of the atmosphere and a powerful jet streak. As a result, snow showers have broken out across much of the Northeast US and Mid-Atlantic region and they are dropping southeastward at this hour towards the DC-to-Philly-NYC corridor. There is the chance for a heavier burst of snow in some spots which can cause small accumulations and quickly developing slick spots on the roadways. High pressure resumes control of the weather for the latter part of the work week.

A cold front will approach the region today from the northwest and it has some support in the upper part of the atmosphere with a robust wave of energy and a powerful jet streak. As a result, there can be snow shower activity in the region primarily during the late morning and early afternoon hours. The highest chance for snow shower activity will be across the northern suburbs where small accumulations are possible and slick spots on the roadways. Skies will clear tonight and high pressure will take control for the latter part of the work week. It turns milder this weekend ahead of the next strong cold frontal system which is likely to be accompanied by some rain shower activity in the Mid-Atlantic region. A colder air mass arrives early next week after the passage of the weekend cold front and we'll have to monitor a possible threat of low pressure near the eastern seaboard.

A cold front will arrive in the Mid-Atlantic region on Wednesday and it will be accompanied by a strong wave of energy in the upper part of the atmosphere and a powerful jet streak. As a result, snow showers can break out on Wednesday; primarily, in areas near and to the north of the PA/MD border region, and there is even the chance for small accumulations in some spots. High pressure resumes control of the weather for the latter part of the work week.

Low pressure pushed away from the Carolina coastline on Monday and strengthened out over the open waters of the western Atlantic Ocean. It'll remain chilly today with clouds giving way to some sunshine and then a weak front will approach the area in the overnight hours. That front could generate a shower on Wednesday and then high pressure takes over for the latter part of the week and there will be a warming trend going into the weekend ahead of the next front. The weekend front may be accompanied by some shower activity in the Mid-Atlantic region and it'll be followed by a colder air mass for the early part of next week.

Clouds this morning will give way to partial sunshine as low pressure pushes away from the Carolina coastline and strengthens out over the western Atlantic Ocean. An area of high pressure will build into the region on Tuesday and dominate our weather pattern right into the upcoming weekend. A frontal system will likely arrive late in the weekend and it may be accompanied by some rain activity in the Mid-Atlantic region.
