The last couple of weeks were well above-normal in the eastern half of the nation, but this week will be a lot different with progressively colder conditions. In addition, winds will become quite a factor as they will become very strong on Wednesday and Thursday with gusts to 50 mph possible in the DC-to-Philly-NYC corridor. As far as precipitation is concerned, a strong and active cold front will arrive later this evening with occasional rain showers and there can be a rumble of thunder. Looking ahead, snow continues to be a threat for the weekend in the Mid-Atlantic region. The chances for significant snow this weekend in the DC-to-Philly-to-NYC corridor will ride on the timing of the phasing together of waves of energy in the northern and southern jet streams. Early indications suggest the phasing together of these two systems may not occur until they’re both offshore which would reduce chances for important snow accumulations in the I-95 corridor; however, it is way too early to write off a significant snowfall for the DC-to-Philly-to-NYC corridor.

It’ll turn milder today after a cold, damp start to the day and afternoon temperatures should make it to the upper 40's for highs. A strong cold front will sweep through the region later this evening and likely bring us a round of rain showers before midnight. As low pressure intensifies over New England on Wednesday and strong high pressure edges this way from the Upper Midwest, the pressure gradient will tighten and winds will pick up dramatically. In fact, winds could gust to 45 mph on Wednesday and they’ll stay strong through Thursday to go along with progressively colder temperatures. Looking ahead to the weekend, snow is a threat around here as low pressure pulls out of the Gulf of Mexico at the same time strong, cold high pressure slides eastward across southern Canada. It is still too early to tell how quickly this Gulf storm can intensify by the time it reaches the Mid-Atlantic coastline as that'll depend on potential phasing of a northern stream wave of energy with a southern stream disturbance…stay tuned.

The last couple of weeks were well above-normal in the eastern half of the nation, but this week will be a lot different with noticeably colder conditions. In addition, winds will become quite a factor as they will become quite strong on Wednesday and Thursday with gusts to 50 mph likely in the DC-to-Philly-NYC corridor. As far as precipitation is concerned, a quick burst of snow is possible this afternoon and frozen precipitation is a threat later tonight; primarily, in areas to the north of the PA/MD border. Looking ahead, snow is on the table this weekend in the Mid-Atlantic region as a storm tries to get going near the eastern seaboard.

This looks like quite a cold week in the Mid-Atlantic region with frozen precipitation likely here late tonight, potentially damaging winds at mid-week and perhaps a weekend snow threat. Very cold air has dropped southward through New England from southeastern Canada during the past 24 hours or so and low pressure is headed towards the Great Lakes from south-central Canada. Precipitation is likely to arrive here later tonight and it should be cold enough for a wintry mix of snow, sleet and rain. Some slick spots are possible towards morning along with small accumulations of snow and ice. Another low pressure system and its associated strong cold front will cross the region tomorrow night and usher in a very cold air mass for the mid and late week. In addition, winds will become very strong following the Tuesday night frontal passage with gusts past 40 mph likely on Wednesday and Thursday. Looking ahead, a storm will try to get organized near the east coast this weekend and snow is a threat for the Mid-Atlantic region...stay tuned.

Rain will overspread the area tonight as the next storm system arrives from the southern states and the threat for rain will continue well into the day on Saturday. High pressure will build into the area late tomorrow and the weekend promises to close on a pretty sunny note on Sunday, but it will be windy and chilly. Very cold air will push into southeastern Canada and New England on Monday at the same time a strong cold front slowly advances eastward across the Great Lakes. More rain is likely here by late Monday or Monday night, but with the cold air so close by, it wouldn’t be surprising to see some frozen precipitation at the onset; especially, across some of the northern suburbs. A cold shot arrives from the northwest at mid-week.

Weak low pressure will push away from the east coast this morning, but a second and stronger system will follow close behind. Skies should clear this afternoon as high pressure builds eastward and it should remain dry for much of the day on Friday. Later tomorrow night, rain will overspread the area as the next storm system arrives and the threat for rain will continue into Saturday. High pressure returns for the second half of the weekend, but the weather goes downhill on Monday. Very cold air will push into southeastern Canada and New England on Monday at the same time a strong cold front advances eastward across the Great Lakes. More rain is likely here by late Monday or Monday night and it looks like it will continue into Tuesday.

2018 turned out to be one of the wettest years ever in many spots across the central and eastern US and, in some areas, it turned out to be the wettest on record. For example, Washington, D.C. experienced its wettest year ever in 2018 and Philadelphia wound up in 2nd place just a few inches behind 2011. The first few hours of the 2019 began with some rain in the I-95 corridor and the next few days will feature more rain as tow low pressure systems pull out of the southern states and heads towards the Mid-Atlantic.

A couple of low pressure systems will come out of the southern states and head our way over the next few days. The first system will skirt the Philly metro region late tonight and early Thursday with some rainfall before it pulls away from the east coast later Thursday. The second and stronger system will impact the Mid-Atlantic with periods of rain on Friday night and early Saturday before it then pulls away from the east seaboard. High pressure dominates the scene later this weekend and early next week before a strong cold front likely arrives on Tuesday with showers.

The active weather pattern of late will continue for much of this week with a couple of systems that are likely to impact the Mid-Atlantic region. One low pressure area will slide up to our west over the next 12-24 hours and it will generate more rain for the already-waterlogged Mid-Atlantic region. Temperatures today should reach into the upper 40’s as slightly milder air will surge northward on the warm, eastern side of this storm system. High pressure returns into the Mid-Atlantic region for the bulk of Tuesday and Wednesday and temperatures will trend downward. Another low pressure area will intensify over the south-central US later this week and likely head towards the eastern seaboard with more rain or perhaps even some snow.

As the eastern US suffers through yet another soaking rain event to close out this shortened work week, seeds are already being sown for another rain event early next week as this active weather pattern looks like it will continue right into the new year. Today’s system plunged into the Southwest US earlier this week and is now headed towards the Great Lakes region and well to the west of the I-95 corridor. Given this well inland track, warmer air has surged northward along the eastern seaboard resulting in plain rain around here and it looks like there may be a repeat performance by the atmosphere early next week.
On Monday, strong energy in the upper atmosphere will pull out of the Southwest US and head towards the eastern Great Lakes - once again keeping the east coast in the warm sector with plain rain likely from later Monday into early Tuesday. Colder air will then filter into the Mid-Atlantic region at mid-week at the same time another strong wave of energy drops into the Southwest US. It is still unclear and many days away, but there is a chance that this system may end up taking more of a southern track late next week which would make it a bit trickier in terms of rain versus snow in the Mid-Atlantic region; however, cold air will likely only be marginal.
