Even in an overall mild weather pattern, there can be some accumulating snow if the timing is just right between low pressure systems and the usually brief cold air outbreaks that can still take place. We are currently experiencing a mild weather pattern here in the Mid-Atlantic region with 70 degrees possible tomorrow afternoon in parts of the I-95 corridor and there will be another significant warm up in the early-to-middle part of next week, but there is also a shot at some accumulating snow this weekend. A strong cold front will usher in much colder air by the weekend and low pressure will pull out of the southern states on Saturday and head towards the Mid-Atlantic coastline threatening us with accumulating snow as well as ice and rain.

A warm front will approach the region later today and it should generate some shower activity around here during the overnight hours. After its passage on Thursday, temperatures should jump into the 60’s, but a strong cold front will bring an end to the warm up by the weekend. This cold front will likely bring more rain to the area tomorrow night and on Friday and then colder air pushes in by the early part of the weekend. At the same time the cold air arrives, low pressure will try to push northward from the southern states along the stalled out frontal boundary zone. If that system can make it this far north - and it appears increasingly likely - it may be just cold enough for some snow in the region by late Saturday.

Even in an overall mild weather pattern, there can be snow threats this time of year. Indeed, the I-95 corridor may experience temperatures near 70 degrees on Thursday, but then a strong cold front will bring dramatically colder temperatures by the weekend and low pressure is going to try to push in this direction from the southern states. If that system can make it this far north – and this is on the table, but not yet certain – then it may be just cold enough for some snow in the region over the weekend before it warms up again next week. Longer term, there are signs for a return to more sustained cold in the eastern US come late February and March.

There is abundant very cold air around in the Northern Hemisphere (e.g., Arctic dips to -76°F) as we reach the mid-point of February and snowfall has been very impressive in recent days from British Columbia-to-Chicago-to-Paris-to-Moscow, but unless the atmospheric flow pattern changes, this abnormal cold and potential snow won’t necessarily come to the eastern US. In fact, the weather pattern in the eastern US has featured multiple mild spells in recent days and little in the way of snowfall for the immediate I-95 corridor, and the overall mild weather pattern looks like it will continue for the next week-to-ten days. After that, however, there are numerous signs that suggest there will be a crucial change to the overall atmospheric pattern over the Northern Hemisphere and this will likely allow for multiple cold air outbreaks to once again be directed into the eastern US.

Chilly high pressure will control our weather today, but it’ll drift out to sea in the overnight hours and a warm front will approach the region tomorrow from our south. The warm front is likely to result in some rain around here tomorrow night and showers could linger into Thursday which will become a very mild day with highs likely reaching 60 degrees. A strong cold front will slowly slide through the region on Thursday night and Friday generating more rain and then colder air pours in by the early part of the weekend. We'll have to monitor the chance for low pressure to push this far north over the weekend as it could be just cold enough for some snow.

We’ll finally get some drying later today following the long-lasting soaking rain event this weekend as low pressure slowly pulls away and high pressure builds into the region. Temperatures today will be noticeably cooler than yesterday, but not bad at all for this time of year. In fact, there is no extreme cold in sight as our overall mild weather pattern continues and temperatures could climb back to near the 60 degree mark by Thursday before a late week cool down. One final note, Central Park received 1.79 inches of rain over the weekend.

It has been very dry in recent months in the DC metro region and drier-than-normal in the Philly and New York City metro regions, but heavy rain is headed this way for the upcoming weekend and that, combined with rains earlier this week, should help alleviate some of the dry conditions in the area. Multiple waves of moisture-laden low pressure will slowly ride up along a frontal boundary zone this weekend from southwest-to-northeast and by the time the weekend ends, many spots in the DC-to-Philly-to-NYC corridor will have received 1.50-2.50 inches of rainfall. Even heavier amounts of rainfall may pile up in the Tennessee Valley from this weekend system where some spots could receive 6+ inches by early Monday morning.

A soaking rain event is headed to the area for the upcoming weekend and it should result in 1.5-2.5 inches of rain by the end of the weekend. The heaviest rain will likely occur late tomorrow night and early Sunday, but this will be a rather long precipitation event with about a 24-hour period of rainfall from late Saturday to late Sunday. High pressure pushes off the east coast today and this will open the door for Gulf of Mexico moisture to ride northward from the Deep South towards the Mid-Atlantic. In addition, Atlantic Ocean moisture will feed into this slow-moving low pressure system as low-level winds turn to an east-to-southeast direction early this weekend. It’ll turn slightly milder later today compared to yesterday, but there will be plenty of clouds around as a weak disturbance passes by to our north. Even milder air moves in for the weekend to accompany the soaking rain event and temperatures should pass the 50 degree mark by Sunday afternoon.

It has been very dry in recent months across the DC metro region and drier-than-normal in the Philly and NYC metro regions, but a soaking rainfall is headed this way for the upcoming weekend and that, combined with rains earlier this week, should help alleviate some of the dry conditions in the area. Moisture-laden low pressure will slowly ride up along a frontal boundary zone this weekend from Texas to the Northeast US and by the time the weekend ends, many spots in the DC-to-Philly-to-NYC corridor could have received two or more inches of rainfall.

Low pressure has pushed away from the region and high pressure will take control with cold, breezy and dry conditions. Temperatures will struggle to reach the freezing mark for afternoon highs, but we’ll begin to turn milder on Friday and then even warmer this weekend. Unfortunately, the weekend warm up will coincide with some rain later Saturday into Sunday.
