The potential continues for accumulating snow this weekend in the I-95 corridor as low pressure forms off the Mid-Atlantic coastline, but amounts are still uncertain as questions still remain on the exact storm track and speed of intensification. One possible solution is that a storm intensifies quite rapidly later this weekend and "hugs" the Mid-Atlantic coastline - this scenario would produce more in the way of snow accumulation for the DC-to-Philly-to-NYC corridor. Another possible outcome is that the storm is farther east in a location well off the coast and it intensifies more slowly - this would lead to less snow for the Mid-Atlantic I-95 corridor region. Preliminary snowfall estimates are 1-3 inches in the DC metro region, 2-5 inches in the Philly metro region, and 3-6 inches in and around NYC - all still subject to change. The snow would be of the wet variety and would accumulate primarily on non-paved surfaces roughly in the time period of Saturday night into Sunday night. Stay tuned.

A cold front will arrive later today with scattered showers and thunderstorms and its passage will send high temperatures down some ten degrees or so between this afternoon and tomorrow afternoon. An even more important and stronger cold front will push through the region late Friday and this frontal passage will usher in noticeably colder (Arctic) air for the weekend as cold high pressure builds to our north. By early Sunday, attention will shift to the east coast as it is quite likely that a strong storm will form near the Mid-Atlantic coastline and - given the cold air that will be in place - there is a possibility for accumulating snow in the DC-to-Philly-to-NYC corridor with several inches on the table.

The real "March Madness"...signs continue to point to the threat for a strong coastal storm late Sunday that could bring significant accumulating snow to the I-95 corridor from DC-to-Philly-to-NYC. A cold front will approach the region today and its passage will bring scattered showers and thunderstorms and high temperatures down some ten degrees between this afternoon and tomorrow afternoon. An even stronger cold front will push through later tomorrow and its passage will usher in noticeably colder Arctic air for the weekend as high pressure builds in to our north. By late in the weekend, strong low pressure is likely to form near the Mid-Atlantic coastline and it could actually generate accumulating snow in the I-95 corridor with several inches of wet snow on the table - stay tuned.

Today and Thursday will be quite mild in the Mid-Atlantic region with high temperatures well up in the 60’s in most spots and perhaps even 70+ degrees in the DC metro region. A cold front will arrive on Thursday and its passage will send high temperatures down some ten degrees or so between tomorrow afternoon and Friday afternoon. An even more important and stronger cold front will push through the region late Friday and this frontal passage will usher in noticeably colder (Arctic) air for the weekend as cold high pressure builds to our north. By Sunday, attention will shift to the east coast as it is quite likely that a storm will form near the Mid-Atlantic coastline and - given the cold air that will be in place - there is a possibility for accumulating snow in the DC-to-Philly-to-NYC corridor. By the way, looking far ahead, there are signs for multiple cold air outbreaks as we wind down the month of March and begin April.

Today will likely turn out to be the mildest day of the week with temperatures climbing into the 70’s, but it’ll stay unsettled as well with a good chance of showers this afternoon and early tonight and maybe a thunderstorm or two. A cold front will approach on Thursday keeping it unsettled around here and a downward trend in temperatures will begin following the passage of that front. A secondary cold front will produce another threat for showers in the Mid-Atlantic region late Friday and then building high pressure to our north will usher in progressively colder air this weekend. By late Sunday, there are signs that a storm will form near the east coast and this potential storm could actually bring snow to portions of the Northeast US and Mid-Atlantic region, but there are still several days to go to this possible event so stay tuned – we’ll monitor it closely.

Tomorrow will likely be the mildest day of the week with high temperatures well up in the 60’s in much of the I-95 corridor – perhaps even 70+ degrees in the DC metro region – but then a couple of cold fronts will create a downward trend in temperatures around here late in the week and this weekend. One cold front arrives on Thursday in the Mid-Atlantic region and this will be followed by a secondary push of colder air late Friday. By the early part of the weekend, building high pressure to our north will usher in progressively colder air and then attention will shift to the east coast at the end of the weekend for the potential of a coastal storm.

The weather remains unsettled for the next couple of days with a continuing shower threat, but it also becomes increasingly milder. A colder pattern then begins later this week following the passage of a cold frontal system on Thursday. By the weekend, high pressure will usher in progressively colder air and there are signs for a coastal storm by the end of the weekend. Depending on the track of this potential coastal storm, snow could actually fall in portions of the interior Northeast US by late Sunday or early Monday. Stay tuned.

An area of moisture from the south-central US has pushed into the Mid-Atlantic region and it’ll stay damp and unsettled into tomorrow. High pressure is going to build into the region for the mid-week time period with Wednesday probably turning out to be the mildest day of the week and then a cold front approaches on Thursday. This front will usher in a colder period of weather for about a week to ten days in the Mid-Atlantic region and snow could actually make a return to portions of the interior Northeast US during this colder stretch. In fact, there are signs for a significant coastal storm around next Sunday which could generate snow in the interior Northeast US (i.e., areas to the NW of I-95; odds favor rain in the big cities) and that may not be the last chance for snow in this part of the country.

A weak cool front passed through the region in the overnight hours and we’ll be some 15 degrees cooler today as a result; however, it’ll still be well above normal for this time of year. High pressure from the Upper Midwest will build into the region today and remain in control of our weather on Saturday, but then moisture from the south-central US will make a push towards the Mid-Atlantic region during the second half of the weekend. Consequently, clouds will increase on Sunday and showers are quite likely around here by later Sunday night and on Monday. Looking ahead, the overall relatively mild weather pattern looks like it will continue for another week or so, but more cold air outbreaks are likely to return to the region later in the month.

High pressure remains anchored off the east coast this morning and southwesterly winds on its backside will bring more record warmth to the Mid-Atlantic region. A weak cool front, however, will push in overnight from our northwest and high temperatures will drop some 15 degrees on Friday behind the front compared to today's potential record warmth. High pressure will remain in control on Saturday, but clouds will increase on Sunday and showers are likely by later Sunday and Monday. Looking ahead, the overall weather pattern stays relatively mild for another week to ten days, but there are signs for multiple cold air outbreaks later this month so enjoy the warmth while we have it.
