Conditions will remain quite unsettled around here today with a stiff wind, plenty of clouds, and likely occasional showers as strong low pressure spins southwestward over the western Atlantic Ocean. This low pressure system will finally make a permanent exit early this weekend and begin to move out over the open waters of the North Atlantic. As a result, it’ll become somewhat more settled around here on Saturday and Sunday and a warming trend will begin. It’ll turn out to be quite a decent day on Monday with plenty of sunshine and quite mild conditions, but showers are likely to return to the area on Tuesday night and Wednesday.

Conditions will remain unsettled over the next couple of days because of the atmospheric roadblock that an offshore strong storm is going to encounter. Winds will increase noticeably today around here as the offshore storm intensifies and begins a loop back towards the NE US coastline. The increased winds will continue tonight and on Friday as well. In addition, there will be a band of clouds and showers that will rotate around the low pressure system and actually drop southwestward later tonight into Friday from the Northeast US to the Mid-Atlantic region. This low pressure system is likely to finally make a true exit during the early part of the weekend into the open waters of the North Atlantic and this will lead to much more settled conditions on Saturday and Sunday with much milder temperatures going into the early part of next week. In fact, Monday is looking like a very nice day with sunshine and warm conditions.

One thing a snow lover in the central and eastern US is rooting for during the wintertime is a “high-latitude blocking” pattern in the upper part of the atmosphere as it is often favorable for sustained cold air outbreaks and potentially accumulating snow. One way meteorologists can monitor the likelihood for this type of weather pattern is to track a teleconnection index known as the North Atlantic Oscillation (NAO). If this index falls into “negative” territory for a sustained period of time during the wintertime – a snow lover’s dream – it is often associated with sustained colder-than-normal weather in the eastern and central US and an increased chance for accumulating snow. Here we are now into the month of April and the largely absent “-NAO” pattern this winter season has finally arrived with “high-latitude blocking” likely for the next week or two across the northern latitudes. This may not lead to snow this time of year – although stranger things have happened – but it does signal the likely continuation of cold air outbreaks into the central and eastern US through at least the middle of April.

Low pressure is pushing off the North Carolina coastline this morning and it’ll head to the northeast out over the open waters of the western Atlantic. It will not, however, continue in this direction for much longer before it encounters a blocking pattern in the upper part of the atmosphere which will lead to an unusual movement in coming days as it will retrograde back towards the Northeast US. The offshore storm will likely result in unsettled conditions around here during the next few days with plenty of clouds today thanks to chilly air aloft which makes it unstable as well as plenty of low level mositure. On Thursday, as this offshore system strengthens and begins to loop back around towards the coast, the NW winds will pick up in intensity gusting to 25 mph or so. By Thursday night or early Friday, a band of clouds and showers may actually drop southwestward through the Northeast US and into the Mid-Atlantic region as the offshore low makes its closest approach. Over the weekend, high pressure from our west is likely to bring about more settled conditions around here and milder temperatures.

Low pressure will push off the Carolina coastline later tonight and make a move to the northeast out over the open waters of the western Atlantic. It will not, however, continue in this direction for too long before it encounters a blocking pattern in the upper part of the atmosphere which will lead to an unusual movement in coming days as it will retrograde back towards the Northeast US. This low pressure system is producing rainfall today across the southern Mid-Atlantic and then, as it retrogrades back around late this week, it could swing a band of clouds and showers from northeast-to-southwest through the Northeast US and into the Mid-Atlantic region.

A cold front passed through the region late yesterday and it’ll turn out to be cooler today with plenty of clouds and perhaps a shower or two. Low pressure is pushing east across the southern US and will exit off the Carolina coastline late tonight. High pressure will build across the region for the second half of the week generating mainly rain-free conditions in the Mid-Atlantic region.

There will be some improvement today following a wet weekend and temperatures will climb to rather comfortable levels this afternoon near the 60 degree mark. High pressure will build across Canada as we begin the new work week at the same time moisture will be increasing in the south-central US. Low pressure will form during the next couple of days over the Tennessee Valley and, while some of its moisture will reach the area, the worst of its impact will stay to our south.

Today will turn out to be a decent day with partial sunshine and mild conditions, but occasional rain is headed our way for the weekend. A cold front has dropped through the region and it’ll stall out to our south by tonight. This front will turn around on Saturday and head northward as a warm front producing more rain in the area - some of it heavy at times - and then a cold front will approach on Sunday with additional showers likely and perhaps an afternoon or evening thunderstorm. There is the threat for another storm by the middle of next week, but it is still unclear as to how far to the north and east it will come.

The active weather pattern that we have been experiencing across much of the nation in recent days will continue at least into the middle of next week. Low pressure over the middle of the nation this weekend will keep much of the eastern half of the nation unsettled and there are signs that a significant storm may form by the middle of next week. The potential is there for a strong storm to develop next week in the south-central US and then head northeast towards the Mid-Atlantic region and it could have a wide-ranging impact on a large part of the eastern third of the nation.

There will be a brief break in the action today from our recent wet weather pattern with a pretty nice day in store and high pressure building into the region. However, another unsettled and wet period begins late tonight and continues into the upcoming weekend. Low pressure will ride along an approaching cold frontal system on Friday and there can be showers associated with it from late tonight into early Friday. This front will stall to our south by the beginning of the weekend and then turn around and come back north as a warm front. As a result, more rain is likely on Saturday and then as a cold front approaches late in the weekend, additional showers will be possible on Sunday. There is the threat for another storm by the middle of next week which could become quite strong and expansive and potentially have an impact on much of the eastern third of the nation.
