A very active weather pattern will likely continue across the eastern half of the nation into the early part of May in large part due to a continuation of cold air outbreaks from Canada into the central and eastern US. These on-going cold air outbreaks are combining with increasingly warm and humid conditions across the southern US to help in the generation of storms and also has increased the chances for severe weather outbreaks; especially, across the southern states. In fact, tornadoes this year are running at above-normal levels and are the highest for the month of April since 2011. The next storm in a series of storms will impact the Mid-Atlantic region from today into late Friday and then another system arrives over the upcoming weekend and colder-than-normal conditions will persist through the period.

Our active weather pattern will persist as long as cold air outbreaks continue to drop into the central and eastern US from Canada and indications are that this flow will continue into at least early May. The next storm in a series of storms is going to impact the region from today into late Friday. There can be a couple of showers this morning even with some ice pellets mixed in and there periods of rain develop late in the day. There can be some soaking rainfall in the overnight hours and into the day on Friday and, given the recent soaking rainfall, the chances for localized flooding will increase during this event. Yet another storm is likely to follow over the weekend with more rain from late Saturday into Sunday and this will be followed by yet another cold air outbreak during the early part of next week. Beyond that, you guessed it, another storm system may follow by late Tuesday and there can be more cold air behind that…and the same pattern just goes on and on and on.

Our active weather pattern will likely persist as long as cold air outbreaks continue to drop into the central and eastern US from Canada. Indications are that this pattern is likely to continue into at least early May leading to multiple storms in coming days and the potential for new severe weather outbreaks in parts of the country. After a chilly and windy day on Wednesday, the next storm in a series of storms is likely to impact the Mid-Atlantic region from later tomorrow into Friday. Given the recent rainfall and the expectation of some soaking rain with this next system, the concern for localized flooding will probably rise in the Mid-Atlantic region on Thursday night and Friday. Yet another storm is likely to follow over the weekend with more rain in the DC-to-Philly-to-NYC corridor from later Saturday into Sunday. Following the weekend storm, yet another cold air outbreak is likely to reach the Mid-Atlantic region after dropping southeastward from Canada into the Great Lakes region and there is no sign of sustained warm weather through at least the beginning of May.

A very active weather pattern continues for much of the nation aided by a continuing influx of cold air masses from Canada into the central and eastern US. A strong cold front at the leading edge of the next cold air outbreak will arrive this afternoon in the DC-to-Philly-to-NYC corridor and there can be strong thunderstorm activity with very gusty winds and hail the primary threats. Much colder air will push into the region in the overnight hours riding in on stiff NW winds and temperatures in many suburban locations by early tomorrow will once again be at or slightly below the freezing mark. Multiple chances of rain will follow in coming days and there will be additional cold air outbreaks for the central and eastern US - perhaps into the early part of May.

The overall active weather pattern will continue for at least another week or so with multiple chances of rain and there will be additional cold air outbreaks in the central and eastern US. A strong cold front will approach the region today causing shower activity and there can be a strong-to-severe thunderstorm with damaging winds and hail a threat. Following the passage of the cold front, much colder air will return late tonight on stiff NW winds and temperatures will once again drop way down into the lower 30’s for overnight lows which is way below-normal for this time of year. Another low pressure system is likely to impact the region with more rain later Thursday and Thursday night and yet another storm could follow over the upcoming weekend. The weekend storm will be followed by another cold air outbreak for the early part of next week.

The overall active weather pattern will continue with multiple chances of rain over the next week or so and there will be a continuation of cold air outbreaks for the central and eastern US. Low pressure will push away from the Mid-Atlantic coastline today – perhaps causing a lingering shower or two - and then a cold front will approach the area on Tuesday. This next cold front will bring showers to the area on Tuesday and then another chilly air mass for this time of year will arrive tomorrow night. Another low pressure system is likely to impact the region with more rain on Thursday night and Friday and yet another storm could follow late in the upcoming weekend.

After an unusually cold morning for the middle of April clouds will increase ahead of a frontal system that will bring us occasional rain tonight into early Saturday. High pressure will return later tomorrow and dominate the weather until late in the weekend. Late Sunday into Monday, low pressure will head towards the Mid-Atlantic coastline and it could brush us some rain on Sunday night and early Monday…a close call. Another cold front should sweep through the region on Tuesday with more shower activity possible.

The passage of an overnight cold front will keep us well below-normal today in terms of temperatures despite some sunshine. After another cold night with lows near freezing and some patchy frost, low pressure will head our way from the Ohio Valley on Friday and result in occasional rain showers from late tomorrow into early Saturday. High pressure will then build into the region this weekend and it should result in some sunshine on both weekend days.

Low pressure will push away from the area this morning and it’ll remain quite chilly for the middle of April despite some sunshine. A reinforcing cold front will arrive in the overnight hours – perhaps with a snow shower or two – and temperatures will drop way down into the low-to-mid 30’s late tonight and again late tomorrow night and frost is possible as well. Another low pressure system will head in a west-to-east fashion on Friday and it’ll likely produce another round of rain showers in the region during the afternoon and evening hours. Additional cold air outbreaks will drop into the central and eastern US as we progress through the second half of April.

Following the passage of yesterday’s strong cold front, colder air moved into the region in the overnight hours. The cold front has stalled out along the east coast and low pressure will form later today along the frontal boundary zone. The low will ride up to the northeast and generate some rain showers in the area from late tonight into Wednesday. It can be just cold enough in some areas for a few flakes of snow to mix in at times; especially, in the higher elevation locations to the north and west of I-95. The colder-than-normal weather for mid-April will stick around through the remainder of the week and there will be additional cold air outbreaks as we progress through the second half of April.
