A “clipper-like” low pressure system will drop southeastward across the Great Lakes today and it is bringing some rain and snow shower activity to the Mid-Atlantic region. This system will also drag a cold front through the area and much colder-than-normal air will head into the region for the weekend after a brief spike in temperatures this afternoon. A couple of waves of low pressure will form along this cold frontal boundary zone on Saturday and likely throw some mixed precipitation into the region, but it doesn’t appear to be a significant event. Stay tuned, however, as there are still some uncertainties on tomorrow's system(s).

An active and cold weather pattern will continue for the Mid-Atlantic region into the middle of next week with additional cold air outbreaks and the threat for more early spring snow. After a blustery and cold day today, a “clipper-like” low pressure system will drop southeastward across the Great Lakes on Friday and it will bring some rain and snow shower activity to the Mid-Atlantic region. This system will drag a cold front through the area and much colder-than-normal air will flood the region for the weekend after a brief warm up on Friday afternoon. A wave of low pressure will form along this cold frontal boundary zone and likely throw some snow into the I-95 corridor on Saturday, but it doesn’t appear to be a significant event. Yet another low pressure system may impact the Mid-Atlantic region in the early part of next week.

After a brisk and cold day today with possible scattered flurries, a “clipper-type” low pressure system will bring rain showers to the region late tonight and on Friday and the rain could be mixed with snow at times. In fact, there could be a coating of snow in the early morning hours across many suburban locations before it turns milder later in the day. This low pressure system will push a cold front through the region by early Saturday which will usher in a very cold air mass for this time of year. A wave of low pressure will form along the frontal boundary zone on Saturday and precipitation will likely break out early in the day. The precipitation is likely to begin as rain or a wintry mix and then change to snow during the day on Saturday and some accumulations are likely along the DC-to-Philly-to-NYC corridor. It stays abnormally cold on Sunday following the Saturday storm and another system could impact the region early next week.

A very active weather pattern is bringing the I-95 corridor intense winds today associated with a strong cold frontal system and there may be another round of springtime accumulating snow this Saturday for parts of the region. Winds could gust past 50 mph this afternoon and early evening following the passage of a strong cold front as a fresh cold air mass rushes into the region. On Thursday, it’ll be blustery and quite cold for this time of year and the winds will start off the day quite strong though they will likely diminish during the mid and late afternoon hours. A “clipper-type” low pressure system will then bring rain and snow showers to parts of the I-95 corridor on Friday and also push a cold front through the region. This front will usher in very cold air for this time of year and low pressure will form along the stalling frontal boundary zone and likely generate some accumulating snow in the DC-to-Philly-to-NYC corridor.

A warm front pushed through the region last night and today will feature the mid-day arrival of a strong cold frontal system that can generate damaging wind gusts of up to 60 mph and isolated power outages. This strong cold front produced severe weather yesterday in the Ohio Valley and there can be damaging wind gusts around here both when a line of showers and storms arrives at mid-day and then following the frontal passage later this afternoon as temperatures drop and winds shift to NW from SW. Much colder air pushes in overnight and it’ll be windy and cold on Thursday. Low pressure will then trek southeastward on Friday across the Great Lakes and it’ll advance a cold front in our direction. That front will pass through the area by the early part of the weekend and usher in a very chilly air mass for this time of year. Low pressure may then form along the stalling out cold frontal boundary zone on Saturday and threaten us with accumulating snow. Stay tuned.

The overall weather pattern in the Mid-Atlantic region will remain colder-than-normal into at least the middle of April, but that doesn’t mean every single day will be below-normal. In fact, temperatures on Wednesday will jump into the 60’s in the DC-to-Philly-to-NYC corridor ahead of a cold front which could generate thunderstorms and strong wind gusts, but then much colder air returns for tomorrow night and Thursday. Another strong cold front will arrive on Friday and low pressure will likely form early in the weekend along this frontal boundary zone as it stalls out just south of here. This system could very well produce accumulating snow in the I-95 corridor on Saturday and that may not be the last threat of snow in this seemingly never-ending active and cold weather pattern.

A warm front will push through the region later tonight and it will generate occasional rain in the area and some patchy fog could form in the overnight hours. A strong cold front will arrive on Wednesday bringing with it occasional showers and maybe a strong thunderstorm or two and it’ll become much milder just ahead of the front. It promises to be a breezy and cold on Thursday and then there is another strong cold front to deal with on Friday. Colder conditions this weekend could be accompanied by some snow depending on the movement of low pressure along a frontal boundary zone. One final note, yesterday’s snowfall was the highest amount in April (5.5” at Central Park) since the great blizzard of April 6-7, 1982.

Low pressure will pull away from the region today and any snow this morning will likely wind down by mid-day as rain or a mix of rain and snow and the afternoon could feature some clearing skies. Total accumulations of 2-4 inches likely with isolated higher amounts possible and there can be some slippery spots for the morning commute. A warm front will generate showers on Tuesday and then a strong cold front will produce some rain here on Wednesday. It promises to be a windy and cold day on and then there is another snow threat during the upcoming weekend.

This is no April Fool’s joke…accumulating snow is coming to much of the I-95 corridor late tonight and early Monday. There have been two threats to monitor for this upcoming week in terms of the potential for snow and the first one is indeed going to result in accumulating snow and the second threat is still definitely on the table for next weekend.

Temperatures at mid-day on Friday are near 70 degrees in the DC metro region and in the 60’s in the Philly and NYC metro regions, but next week continues to look quite different with colder-than-normal air masses headed our way. In additional to the colder air masses, there are two snow threats that will have to be monitored – one late Sunday night into early Monday and then another is possible at the end of next week or next weekend.
