Discussion

Our return to a winter-like weather pattern has begun with the latest influx of cold air and now attention turns to a very good chance of accumulating wet snow on Friday in the I-95 corridor. With cold air in place, low pressure will organize along the Mid-Atlantic coastline early Friday and then gradually intensify as it moves to the northeast. “Elevation” typically plays a critical role in late season snowfall amounts and this could lead to a wider range compared to normal on Friday across metro regions with respect to overall accumulations. The highest accumulations will likely take place on grassy surfaces in elevated locations to the north and west of the big cities and there certainly can be slippery conditions on the roadways.

Here is the breakdown for the I-95 corridor:

DC: Snow is likely to break out after midnight and continue into early Friday morning. The snow is then likely to mix with and change to plain rain later in the morning, but not before there are accumulations on the order of a coating to 3 inches with the higher amounts in that range on grassy surfaces in elevated locations to the west and north of the District.

Philly: Snow is likely to break out right around daybreak on Friday and continue through much of the day. The snow can mix with rain later in the day; especially, in Philly and nearby points to the south and east, but it could remain as all snow well to the north and west of Philly. Accumulations on the order of 2-5 inches are possible with the higher amounts in that range on grassy surfaces in elevated locations to the north and west of Philly.

NYC: Snow is likely to break out early Friday and continue through much of the day. The snow can mix with rain later in the day in NYC and nearby points to the south and east, but it is likely to remain as all snow to the north and west of the NYC metro region. Accumulations on the order of 2-5 inches are possible with the higher amounts in that range on grassy surfaces in elevated locations to the west of the NYC metro region.

One final note, it’ll turn milder on Saturday causing some snow melt, but then another cold air mass will arrive early next week and there may actually be another snow threat in the I-95 corridor by the middle of next week.

Discussion

A strong cold front passed through the region yesterday and it has ushered in a major change to the overall weather pattern back to colder-than-normal conditions for the Mid-Atlantic region. This change will not be a short-lived and general colder-than-normal weather is likely through the remainder of March and into the first part of April. Temperatures today will struggle to pass the 40 degree mark after soaring through the 50's on Tuesday.

In addition to the renewed cold, there may be multiple snow threats for the I-95 corridor over the next few weeks including one this Friday as low pressure organizes near the Mid-Atlantic coastline with fresh cold air in place. Snow should break out early Friday and it could mix with rain later in the day in portions of the metro region. Initial snowfall estimates are for 1-3 inches of accumulation with the higher amounts on grassy surfaces in higher elevation locations to the north and west. After a milder day on Saturday, another shot of cold air is destined to arrive here by early next week.

Discussion

A strong cold front will arrive today and this will begin a major change back to a colder-than-normal weather pattern that should last right through the first part of April. While this does not mean that each and every day through this period will be colder-than-normal, the vast majority of the time will be below normal and there may be multiple threats for snow in the I-95 corridor. In fact, the first threat for snow in the I-95 corridor during this resumption of a winter-like pattern will take place late Thursday night and Friday as low pressure organizes near the Mid-Atlantic coastline with cold air in place. After a milder day on Saturday, another shot of cold air is destined to arrive early next week and there could even be another snow threat later next week for portions of the I-95 corridor. Buckle up, it's going to be a wild ride during winter's last gasp from tonight into the first part of April.

12:30 PM | *Snow threat for late in the week as winter-like pattern resumes following our "spring break"*

[12Z GFS model forecast map for Friday evening with snow (blue) in much of the I-95 corridor; map courtesy "tropicaltidbits.com", NOAA]

Discussion

Overview Our “spring break” period is about to end and a colder-than-normal weather pattern will resume on Wednesday, March 18th, and it looks like it will continue through the remainder of March and into the first part of April. In addition to the change back to the colder-than-normal temperatures, there is the threat for snow late this week as moisture in the southern states, and developing low pressure near the coast, collide with cold air in the I-95 corridor.

Details After a mild day to start the week, Tuesday will feature a strong cold frontal passage in the Mid-Atlantic region. While tomorrow can still be on the mild side, the winds will pick up noticeably and these winds will signal big changes in the offing for Wednesday (and beyond). In fact, temperatures are likely to drop into the 20’s later tomorrow night and struggle to pass 40 degrees on Wednesday in much of the Mid-Atlantic region. Moisture from the southern states will advance northward on Thursday and low pressure will begin to organize near the coast. By later Thursday night and Friday, with cold air in place in the I-95 corridor, it is indeed possible for snow to break out across DC, Philly and NYC as we head into the last day of the work week. The latest (12Z) GFS model forecast map for Friday evening depicts a pretty widespread area of snow (blue) throughout much of the I-95 corridor with low pressure off the coastline. Stay tuned.

Saturday

Partly sunny, cold, chance for snow, mid 40’s

Discussion

The new week will start off rather mild both today and Tuesday, but there will be plenty of clouds around each day and then big changes will take place by mid-week. A strong cold front will arrive on Tuesday and it will usher in an important change to the overall weather pattern with the return of colder-than-normal air to the Mid-Atlantic region for the second half of the week and beyond. In fact, snow is even a possibility at the end of the week as moisture along the coast will push northward at the same time cold air will be in place around here. One final note, Boston, MA broke its all-time snowfall record this weekend for a winter season with more than 108 inches now officially recorded.

Discussion

After a dry and chilly day to end the work week, soaking rain will move into the region late tonight and continue through much of the day on Saturday. Sunday will feature some sunshine, but it’ll be quite breezy and a shower cannot be ruled out. The new work week will start out quiet and mild, but colder air will push into the Mid-Atlantic region by mid-week.

Discussion

The temperature peaked out at 59 degrees late yesterday in Central Park, but a noticeably colder air mass moved into the region from the north in the overnight hours and this will shave about 15 degrees off of our afternoon highs and wind chill values will be even lower. Meanwhile, an area of moisture is gathering together in the Deep South and it looks like it’ll arrive in the form of rain, heavy at times, tomorrow night and Saturday. It’ll stay chilly on Friday ahead of the soaking rain and on the cool side during the upcoming weekend. Looking ahead, it appears that next week will begin on a relatively mild note on Monday, but then colder air will return by mid-week.

Discussion

After a damp start to the day, skies could clear a bit for the afternoon and temperatures should climb right through the 50’s. Colder air will return on Thursday as strong high pressure pushes into the Northeast US from southern Canada. An area of moisture in the southern states will increase our chances for rain as the work week comes to a close and the weekend is likely to start off on the wet side.

Friday

Increasing clouds, cold, chance for rain at night, it could be just cold enough for sleet or snow to be mixed in at the onset, low 40’s

Saturday

Mostly cloudy, cold, chance for rain or snow, low 40’s

Sunday

Partly sunny, cold, the chance for rain or snow showers, low-to-mid 40’s

Discussion

Clouds will dominate the skies today and this will cut temperatures a bit from yesterday and rain is likely to develop late this afternoon and continue this evening. Wednesday will feature some afternoon clearing and temperatures will be quite mild with temperatures climbing well up into the 50’s. Much colder air will move into the Northeast US on Thursday anchored by strong high pressure and temperatures will turn noticeably cooler. It’ll stay quite chilly on Friday and another batch of moisture from the southern states will advance northward towards the I-95 corridor. The result could be rain by Friday night and continuing into Saturday and it could be just cold enough at the onset for sleet or snow to be mixed in.

Discussion

Temperatures today should reach the 50 degree mark with clearing skies and it could climb well into the 50's on Wednesday. Clouds will dominate on Tuesday keeping us slightly cooler than today and rain is likely later in the day and tomorrow night. Late in the week, colder air will be pushing in from the north and a large area of moisture will advance northward into the Mid-Atlantic region from the southern states. As a result, rain or even snow could break out at the end of the work week.
