Given a strong high pressure system positioned to our north and east, low-level winds from a south-to-southeasterly direction will continue to push warm and humid air into the region during each of the next few days. The pattern will be quite unsettled as well with a daily shot at scattered afternoon and evening showers and thunderstorms.

Given a strong high pressure system positioned to our north and east, low-level winds from a southeasterly direction will continue to push warm and more humid air into the region during each of the next few days. The pattern will become unsettled as well with a daily shot at scattered afternoon and evening showers and thunderstorms.

As we start the new work week, an upper-level ridge of high pressure builds across the southeastern states. As a result, low-level winds from a south-to-southwest direction will develop bringing warmer and more humid air into the region. The dry weather pattern will continue as well during the next few days with little to no rainfall expected in the Tennessee Valley.

The 2025 Atlantic Basin tropical season officially gets underway on Sunday, June 1st, and there are signs that the initial threat could come as early as ten days or so from now (i.e., June 8, 9, 10th time frame). A teleconnection index known as the Madden-Julian Oscillation or MJO appears to be foreshadowing the potential of tropical troubles in this time frame as it transitions into a “phase” that is generally quite favorable for activity in the Atlantic Basin. In addition, a second favorable sign may be the evolution of the upper-level pattern of highs and lows across North America which may feature strong ridging over southeastern Canada in about ten days or so. A strong ridge in this part of North America is often favorable this time of year for an “undercutting” tropical system in the southwestern Atlantic, Gulf of America, or Caribbean Sea where sea surface temperatures are generally warmer-than-normal.

After the passage of a slow-moving upper-level low, somewhat drier air has filtered into the region and the threat of showers will be reduced for today and Thursday. Another system will head towards the Great Lakes later in the week and it’ll throw a couple of fronts into the eastern states from Friday into the weekend. As a result, there will be a renewed threat of showers and thunderstorms across northern Alabama in the Friday, Saturday, Sunday time frame to go along with very warm conditions.

A slow-moving upper-level low pressure system will finally push away from the area today, but it’ll be close enough to cause instability in the area and the chance for showers and thunderstorms. That threat of rain will last into tomorrow, but then high pressure takes control briefly on Thursday before another frontal system causes some unsettled conditions at week’s end and during the weekend.

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.
