There is a major warm up coming here later this week and for the weekend, but it will be just a temporary break in the overall cold weather pattern that we have been experiencing for several weeks now. Clouds will thicken up today as low pressure forms along the SE US coastline and there can be some rain and snow shower activity at anytime from today into early tomorrow. It stays chilly at mid-week, but then the warm up begins in earnest on Thursday and the mid-to-upper 70's are quite likely for highs on Friday and Saturday. The transition back to next week's colder weather may not come quietly this weekend as there is likely to be a widespread severe weather outbreak for much of the central and eastern US and a heavy rain event here in the Sunday/Monday time frame.

It is currently about as cold as it ever gets during the month of April in the Northern Plains and Upper Midwest and it’ll turn much colder here in the Mid-Atlantic region this weekend following a brief spike in temperatures this afternoon. In fact, temperatures here this weekend will be some 20-25 degrees below normal for this time of year and this seemingly never-ending colder-than-normal weather pattern is likely to continue into at least the second half of the month. A strong cold front will push through the region later tonight and usher in the next cold air mass for the weekend and a couple waves of low pressure will form along the frontal boundary zone on Saturday making snow an on-going threat in parts of the I-95 corridor.

A “clipper-like” low pressure system will drop southeastward across the Great Lakes today and it is bringing rain and snow showers to parts of the Mid-Atlantic region. This system will also drag a cold front through the area tonight 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 mixed precipitation into the I-95 corridor and there can be some accumulating snow as well. While this does not appear to be a significant event, the second wave of energy that "hangs back" for later tomorrow has to still be monitored as a small shift can have a big impact. Stay tuned.

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 scattered flurries possible, 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 at the onset. 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 just in time for the Nationals home opener. 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 showers 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 for the Nationals home opener 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.

Low pressure will pull away from the region today and any rain or a wintry mix will end early this morning and the afternoon should feature mainly cloudy skies. 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 Thursday for the Nationals home opener and then there is another rain/snow threat during the upcoming weekend.
