Tropical moisture continues to flow up along the eastern seaboard and it is accompanied by a slow-moving upper-level low pressure system. The result here will be another couple of days with occasional showers and thunderstorms can get into the mix as well. After this upper-level low finally “opens up” and exits off to the north and east later in the week, there can be a lull in the action for a brief time. However, another low pressure system will head towards the Great Lakes by the end of the week and it will throw a couple of fronts our way between later Friday and Saturday night. As a result, there will be a renewed threat of showers and thunderstorms from later Friday into Saturday and then drier air should finally return to the region for Sunday and Monday.

A plume of tropical moisture is flowing northward today along the eastern seaboard and this widespread area of moisture is supported aloft by a slow-moving and vigorous upper-level trough of low pressure. The end result here will be another extended period of showers from later today through Thursday and there can be an isolated thunderstorm or two mixed in as well. At week’s end, another system over the Great Lakes will throw a couple of fronts our way and this will renew the threat of showers here from late Friday into Saturday and perhaps even a few strong thunderstorms as well.

It has been unusually dry across much of the Mid-Atlantic region during the past several months, but prospects for getting back to normalcy are looking better and better in what has become an overall wetter weather pattern. In fact, today features an impressive plume of tropical moisture that is flowing right into the Mid-Atlantic region from the southwestern Atlantic Ocean and beneficial rain is falling in most areas. This widespread area of moisture is supported aloft by a vigorous and slow-moving upper-level trough of low pressure and, as such, the threat of showers and thunderstorms will continue through Thursday. After a brief lull in the action later this week, another low pressure system will head towards the Great Lakes and it’ll renew the threat of showers and thunderstorms in the Mid-Atlantic region from later Friday into Saturday. This active weather pattern looks likely to continue through the remainder of the month of May and there will be additional cold air outbreaks as well including potentially one for the Mid-Atlantic region during the Memorial Day weekend.

High pressure slides to our east later today and we’ll have sun followed by late day clouds around to go along with warm conditions. Another slow-moving system is pulling out of the Gulf region and will edge up along the Atlantic seaboard during the next few days resulting in occasional showers around here from tomorrow into Thursday and a couple of thunderstorms can be included as well. In fact, the threat of showers is likely to continue on Friday and Saturday as well as a cold front arrives in the eastern states. Temperatures this afternoon should peak in the upper 70’s, but then be somewhat limited on Tuesday and Wednesday due to an abundance of clouds and the expected shower activity.

It has been unusually dry across much of the eastern US during the past several months with a focus on the Florida Peninsula, but we have been chipping away at these conditions in recent weeks and there are likely to be additional beneficial rainfall events during the new couple of weeks. Rain is falling today throughout much of the Mid-Atlantic region and Northeast US – the second bout of rain this week – and rain is currently falling across portions of the northern Gulf region. This area of Gulf moisture will push east during the next few days and then take a turn to the north early next week and ride up slowly along the Atlantic seaboard. As a result, it appears there will be more beneficial rainfall in the Mid-Atlantic region and Northeast US from later Tuesday into Thursday further alleviating the dry conditions and additional rain threats exist later this month in an on-going active pattern.

There will be additional showers today in the Mid-Atlantic region as a cold front slowly works its way through and an isolated thunderstorm or two is possible. High pressure will take over for the weekend and early part of next week with increasing amounts of sunshine on Saturday and plenty of sunshine on both Sunday (Mother’s Day) and Monday. Another slow-moving system will pull out of the Gulf region early next week and slide up along the Atlantic seaboard. This system will likely result in another round of (welcome) rain for the Mid-Atlantic region from later Tuesday into Thursday of next week.

A day after a stubborn upper-level low pressure system finally departed the Mid-Atlantic region, another one will begin to intensify overhead. At the same time, a cold front will slide slowly southeastward from the Great Lakes and surface low pressure is likely to form along this incoming frontal boundary zone. The end result here will be occasional showers and thunderstorms from later today into late Friday and some of the rain can be heavy at times.
The weather for the weekend and early part of next week is shaping up quite nicely with increasing amounts of sunshine expected on Saturday and mostly sunny skies likely on Sunday and Monday along with comfortably warm conditions. Beyond that, another unsettled weather period develops in the Mid-Atlantic region as as a Gulf system likely rides up along the Atlantic seaboard by later Tuesday and Wednesday.

The stubborn “closed” upper low that has been impacting our weather since the weekend will finally slide to the northeast today as it “opens up” enough aloft to get captured by the polar jet. As a result, our weather will improve today featuring plenty of sunshine with comfortably warm conditions. A cold front will then drop slowly southeastward on Thursday crossing the Great Lakes and reaching the Mid-Atlantic region by late in the day. At the same time, a new upper-level low will develop over the Mid-Atlantic region and surface low pressure is likely to form along the cold frontal boundary zone. The end result should be more showers and thunderstorms around here from later tomorrow into Friday and perhaps even a period of steadier rain. The weekend and early part of next week are shaping up quite nicely with increasing amounts of sunshine expected on Saturday and mostly sunny skies on Sunday and Monday. Beyond that, another unsettled period develops in the Mid-Atlantic region by the middle of next week with a Gulf system likely to ride up along the Atlantic seaboard.

A “closed-off” upper-level low pressure system will continue to produce bands of showers today in the Mid-Atlantic region and there can be some strong thunderstorm activity as well during the afternoon and evening hours. The stubborn “closed” upper low will edge to the northeast on Wednesday as it “opens up” enough to get captured by the polar jet and our weather should improve at mid-week though a shower or two cannot be ruled out.
A cold front will then drop southeastward on Thursday crossing the Great Lakes and reaching the Mid-Atlantic region by late in the day. At the same time, another upper-level low will develop over the Mid-Atlantic region and surface low pressure is likely to form along the cold frontal boundary zone. The end result could be more showers and thunderstorms around here from later Thursday into Friday and perhaps even a period of steadier rain. The weekend could turn out to be pretty decent with increasing amounts of sunshine on Saturday and mostly sunny skies on Sunday. However, upper-level lows are notorious for throwing some curve balls to the weather forecaster so not quite ready yet to give the “all-clear” signal about the weekend.

Some spots in the Mid-Atlantic region were hit by drenching showers and thunderstorms this past weekend while other locations (often right nearby) received much less rain than anticipated. There will be opportunities for more rain in all areas through tomorrow night and some of the rain can be heavy at times. A slow-moving upper-level low pressure system currently centered over the Ohio Valley will continue to produce unstable atmospheric conditions in the region leading to additional bands of showers and thunderstorms.
While the weather settles down a bit on Wednesday as the upper-low grudgingly lifts its way to the northeast of here, there can still be a few showers in the area and perhaps even a thunderstorm or two. A cold front will then drop southeastward on Thursday crossing the Great Lakes and reaching the Mid-Atlantic region. At the same time, an upper-level low will try to re-develop over the Mid-Atlantic region and low pressure may form along the frontal boundary zone. The end result could be more showers around here later Thursday and potentially even some steadier rain from Thursday night into Friday. The weekend may turn out pretty well assuming the late week systems push off to the north and east of here.
