After a couple of very active days in the Tennessee Valley with numerous showers and thunderstorms, the weather will change dramatically today as high pressure builds into the region. As a result, there will be plenty of sunshine, comfortable temperatures, and virtually no chance of rain in the area. The weather remains decent this holiday weekend, but it does get quite warm by the time we get to Monday afternoon with highs back near the 90 degree mark.

The combination of an increasingly humid air mass, strong surface frontal system and a vigorous mid-level low will help generate numerous showers on Friday and Friday night in the Mid-Atlantic region and possible severe thunderstorms. In fact, there may be two bands of thunderstorms to closely monitor during this event- one during the mid-day/early afternoon hours and a second during the late evening associated with the frontal passage. The main severe weather parameter threats will be damaging wind gusts, “flash-flooding” downpours, and isolated tornadoes are even possible. The upper-level low will be rather slow-moving from west-to-east and this is likely to result in an unsettled weather day on Saturday in the Mid-Atlantic region with scattered showers and strong thunderstorms. The upper-level will exit off the coast on Sunday resulting in improvement to end the weekend and the weather on Monday, Memorial Day, should feature plenty of sunshine, very warm conditions and highs well up in the 80’s.

An active weather pattern continues for another in the Tennessee Valley and it can include some strong-to-severe thunderstorm activity with potential damaging wind gusts and heavy downpours. A slow-moving cold front associated with an intensifying upper-level trough will be the main culprit for the numerous showers and thunderstorms. High pressure will take over on Friday and it looks like it may set the stage for a pretty decent Memorial Day weekend though it will get quite warm by Monday.

High pressure will take over at the end of the work week and it looks like it may set the stage for a decent Memorial Day weekend though it will get quite warm by Monday.

In the wake of the departure of low pressure, the day will start off on the dry side, but clouds will increase later as another wave approaches the Mississippi Valley. While the chance of showers and thunderstorms will increase later today and tonight, the rain will be more likely on Wednesday and Wednesday night as an upper-level trough intensifies. In fact, numerous showers are likely in the mid-week time frame around here and some storms that form can be strong-to-severe.

High pressure to the east of here will continue to pump very warm air into the Tennessee Valley and temperatures today and Friday should reach 90+ degrees for afternoon highs. Generally rain-free weather is expected through tomorrow, but the approach of a cool front this weekend will increase the chances for showers and thunderstorms. By the second half of the weekend, temperatures will become more comfortable on the backside of the cool frontal system.

Very warm weather conditions will dominate the scene during the next few days in the Tennessee Valley with highs of 90+ degrees likely in northern Alabama. High pressure will push to the east of here and its backside flow of air will keep it quite warm around here for the mid and late week time periods. The chance of shower and thunderstorm activity will be somewhat limited today, but higher moisture levels on Thursday will increase probabilities.

There are still cold air outbreaks destined to push into the US from Canada as we progress through the second half of May and even accumulating snow for the Rockies, but that doesn’t mean we can’t have a threat of a hurricane. In fact, there are signs that the atmosphere will become supportive of a tropical storm or hurricane in the Gulf of Mexico region later this month or early in June in what is likely to be an active season for the Atlantic Basin.

Today will be another rain-free day in the Tennessee Valley and quite warm as well with afternoon highs well up in the 80’s. Humidity is going to become a noticeable factor for each of the next few days; especially, when compared to the generally dry weather pattern of recent days and weeks. The chance of showers and thunderstorms will increase this weekend, but the passage of a frontal system will likely result in rain-free weather again here early next week.
