Low pressure will push from the central Plains towards the Ohio Valley later today and tonight and it will push a warm frontal system into the region by early tomorrow which will be followed by the passage of a cold frontal system on Friday night. A couple of showers are possible this morning across SE PA and occasional showers are likely later today and tonight. On Friday, it'll turn warmer and there will be occasional rain and perhaps a strong thunderstorm or two. Some of the rain can be heavy at times later tomorrow just ahead of the strong cold frontal system. Winds will pick up noticeably late tomorrow night and Saturday will be a windy, dry day with cooler conditions and mainly sunny skies. Another strong cold front arrives on Sunday with the likelihood of more shower activity in the Mid-Atlantic region.

A cool frontal system passed through the region last night and today will be slightly cooler with a noticeable NW breeze at times. High pressure will continue to control our weather as we begin the day on Thursday, but showers are possible by late in the afternoon and quite likely by later tomorrow night. The shower threat will continue on Friday and there can be a thunderstorm mixed in as well as low pressure pushes a couple of frontal systems through our region. Dry weather is likely to start the weekend in the Mid-Atlantic region, but another shower threat is possible on Sunday as a strong cold front approaches from the northwest.

High pressure takes control of our weather today, but then a cold front can bring some shower activity here tonight - perhaps even an isolated thunderstorm – but this does not look like a significant rain event. After nice weather on Wednesday and Thursday, the combination of northern and southern stream systems could result in more substantial rain here from Thursday night into Friday.

The slow-moving upper-level low pressure system that trekked across the country last week is just now exiting off the Mid-Atlantic coastline and it will be close enough today to impact the region with plenty of clouds and perhaps a few afternoon showers. High pressure takes over for Tuesday, but then a cold front can bring some shower activity here tomorrow night - perhaps even a thunderstorm. After nice weather at mid-week, the combination of northern and southern stream systems could result in some rain here from Thursday night into Friday.

The threat of heavy rain and severe weather will shift today to the eastern seaboard with severe thunderstorm activity possible all the way from the Mid-Atlantic to Florida. The heaviest and steadiest rain will occur in the overnight hours with up to a few inches possible in spots and localized flooding is a serious concern given the already well-saturated grounds. The main area of rain exits off the east coast early tomorrow morning; however, the rest of the weekend will remain quite unstable as a strong upper-level low painfully grinds its way across the region. As a result, instability showers are quite likely here on Saturday and there can be an isolated thunderstorm or two. By Sunday, the upper-level system will be overhead in the Mid-Atlantic region leading to the possibility of lingering clouds and additional instability showers on Easter Day. On Monday, this wave of energy in the upper atmosphere that has impacted much of the nation in recent days will finally exit off the Mid-Atlantic coastline.

Deep upper-level low pressure will intensify over the next 24 hours as it slowly grinds its way across the southern states. The combination of this strong wave of energy in the upper atmosphere and an influx of very moist tropical air will result in a severe weather threat later today and tonight in the Deep South. In addition to the severe weather threat which includes the potential for hail and isolated tornadoes, heavy rainfall is likely later today in the southern states and localized flooding is a concern as grounds are well saturated. The threat for heavy rainfall and severe weather will shift to the eastern seaboard late tomorrow and tomorrow night with the possibility of strong-to-severe thunderstorm activity extending from the Mid-Atlantic region to Florida.

The threat of heavy rain and severe weather will shift to the eastern seaboard late Friday and Friday night with severe thunderstorm activity possible from the Mid-Atlantic region to Florida. While the steadiest and heaviest rain will end by early Saturday, there will likely be some instability shower activity as the upper-level low will still be positioned to the west of the region. By Easter Sunday, the powerful upper-level system and main culprit of this upcoming active weather will begin to weaken, but the atmosphere will remain unstable enough for the chance of additional showers. High pressure ridging takes control on Monday and temperatures will climb well into the 70’s and there should be plenty of sunshine to start the new work week.

Deep upper-level low pressure will intensify over the next couple of days as it slowly grinds its way across the southern states. The combination of this strong wave of energy in the upper atmosphere and an influx of very moist low-level air will result in a severe weather threat today in the region from Texas-to-Kansas and later tomorrow across Mississippi, Alabama and perhaps as far north as Tennessee. In addition to the severe weather threat which includes the potential for large hail and tornadoes, heavy rainfall is likely later today in the south-central states and then on Thursday across the southeastern US. Any heavy rainfall can result in localized flooding as much of the eastern half of the nation is experiencing well-saturated ground conditions. The heavy rainfall and severe weather threat will reach the eastern seaboard on Friday afternoon and evening with the possibility of strong-to-severe thunderstorms from the Mid-Atlantic region to Florida.

A back door cool front passed through the region last night and it’ll turn a bit cooler today with a low-level flow of air out of the northeast. This same front will turn around later tomorrow and advance to the north as a warm front. As a result, it’ll turn warmer on Thursday and become quite warm on Friday along with increasing south-to-southwest winds as we close out the work week. A strong cold front supported by vigorous energy in the upper atmosphere will grudgingly works its way to the east coast at the end of the week and this will result in a soaking rain event for the DC-to-Philly-to-NYC corridor from later Friday into early Saturday. In addition to the heavy rainfall, there is quite likely to be a threat for strong-to-severe thunderstorm activity in much of the Mid-Atlantic region later Friday and Friday night. As the upper-level low crawls to the Mid-Atlantic coastline this weekend, it'll remain mainly cloudy on Saturday and instability showers will remain a threat. Skies should become partly sunny on Easter Sunday, but a shower cannot be ruled out.

Deep upper-level low pressure will slowly grind its way to the east coast late this weekend and during the upcoming weekend and the result is likely to be a major rain event for the DC-to-Philly-to-NYC corridor from later Friday into early Saturday. In addition, vigorous energy in the upper atmosphere will combine with a push of tropical moisture to increase chances for severe weather in the I-95 corridor from later Friday into Friday night to include the possibility of isolated tornadoes. As the deep upper-level low inches overhead on Saturday, instability showers could form, but Sunday should see some improvement as the system finally begins to weaken and pushes off the Mid-Atlantic coastline.
