An active weather pattern continues today with a powerful nor’easter finally starting to pull away from the New England coastline and a vigorous upper-level low over Texas that has resulted in an outbreak of severe thunderstorms and tornadoes in the Deep South. This same upper-level low will push to the east over the next 24 hours and contribute to a windy and rainy end to the week in the Mid-Atlantic/NE US.

An off-shore storm will shift away from the region today and there will be some sunshine, but its proximity will continue to result in windy conditions in the Mid-Atlantic. High pressure will build into the area on Thursday, but then another storm will form near the eastern seaboard from Friday into Saturday. This next system is associated with the energy left behind from the storm that pounded the west coast on Sunday and Monday and it could bring more significant rain and wind to the Mid-Atlantic region. Looking ahead, a cold front is likely to push our way by the middle part of next week.

A nor’easter will intensify off the southern New England coastline today and then it’ll take a loop back towards Long Island later tonight which will prolong its impact around here into tomorrow. An occasional shower is possible here this morning and mid-day and could become more numerous late in the day and early tonight. The bigger impact from the intensifying off-shore storm will be the winds which will increase over the next few hours and potentially gust past 40 mph later in the day and also during the night. Another low pressure system can have an impact around here later in the week as energy from yesterday’s west coast storm reaches the eastern seaboard.

A powerful storm system has pounded the west coast during the past 24 hours or so and a strong Nor’easter is about to unfold just off the east coast. This developing Nor’easter will impact much of the Mid-Atlantic/Northeast US from later tonight into Wednesday morning with flash flooding type rains in some areas and potentially damaging wind gusts; especially, along coastal sections. The development of the east coast storm will wait for the arrival of a surface cold frontal system which will push eastward this afternoon from the Ohio Valley into the Mid-Atlantic. This frontal system can result in some strong-to-severe thunderstorm activity along the I-95 corridor from later today into early tonight following a day of near record warmth.

The passage of a warm front will usher in much warmer air for later today and highs will bounce back into the 70’s after a cool end to the weekend. Low pressure pushes this way from the Midwest tonight and a second one will intensify off the coast on Tuesday. This combination will generate rain in the area from late today into Tuesday and some of it will be heavy at times. In addition, there will be the chance for a strong-to-severe thunderstorm from later today into tonight. The coastal low pressure system will meander offshore at mid-week and another then storm could impact our region late in the week. Looking ahead, the overall pattern changes quite dramatically next week - the first week of November - with a quick start to some winter-like cold on the table.

One strong storm system has impacted the west coast states from Washington-to-California in the past 24 hours or so with significant rainfall, but an even stronger storm is likely have an impact from Sunday into Monday. In fact, this next storm could become the strongest system in many years to impact the region from British Columbia (Canada) to California. Rainfall will be excessive with this next storm, winds will be powerful and potentially damaging, and snow will pile up in the higher elevations of the Sierra Nevada Mountains in eastern California. The upper-level support for this system is likely to then cross the country next week and that could result in a mid-week severe weather outbreak and a late week storm near the eastern seaboard.

A cold front will clear through the region this morning and today will turn out a bit cooler than yesterday and the weekend will be on the cool side as well. While there will be some sunshine on each of the next three days, a shower cannot be ruled at times as weak disturbances will pass by. The best chance in awhile for some decent rainfall in the Mid-Atlantic region will come from later Monday into Tuesday as low pressure pushes to the east from the Midwestern states. Elsewhere, a major storm will slam into the US west coast from Sunday into Monday with tremendous amounts of precipitation and also powerful winds and it could translate into a storm near the east coast by the end of next week.

Much of California and the rest of the western US has been experiencing “extreme” or “exceptional” drought conditions in recent weeks, but that could change in a big way in coming days. A very powerful storm will slam into the US west coast from Sunday into Monday and it could generate a foot or more of rain in the northern part of California and heavy snowfall across interior higher elevation locations of the Sierra Nevada Mountains. In addition, winds associated with this monster storm are likely to be excessive and potentially damaging in many spots along the west coast and even inland. This same system is likely to cross the country later next week and it could wind up as a significant east coast storm by week’s end.

High pressure remains in control of the weather today and it’ll provide some more nice weather in the Mid-Atlantic region ahead of a cool frontal passage that takes place in the overnight hours. It turns cooler behind the front on Friday and stays cool this weekend with some sunshine likely on all three days. The first chance for some decent rainfall around here will come early next week as low pressure pushes into the Mid-Atlantic region. Elsewhere, a big pattern change will take place across California and this will result in substantial rainfall amounts for at least the northern half of California in coming days.

High pressure remains in control across much of the eastern US and the weather will be pretty nice in the local region. A cold front will push through by week’s end and it could result in a couple of showers around here on Friday night and Saturday. An even cooler air mass will follow for the early part of next week with a new high pressure system building into the DC-to-Philly-to-NYC corridor.
