Muggy Air Brings Scattered Showers & Thunderstorms This Weekend...

Good Saturday evening, everyone! The warm and humid air has finally entrenched itself over much of the eastern United States this weekend...and that means it doesn't take much to kick off some showers and thunderstorms. Fortunately...since there are A LOT of outdoor activities going on this weekend, most of these showers and thunderstorms are widely scattered in nature, so it's really a 'hit or miss' type situation. While some areas have seen slow-moving thunderstorms produce torrential downpours today (Roane and Calhoun counties)...Charleston, Huntington and most of the I-64 corridor has remained dry so far thankfully. If the air wasn't so moist and unstable...a very weak upper-level disturbance moving in from the Tennessee Valley would probably come in without consequence; however, with the summer-like air 'willing' to rise on it's own (warm, moist air is buoyant and lighter)...even weak systems can get the job done to kick off some rain here and there. A nearby stationary front will continue to act as a 'focus' for scattered activity, too. So...with this set-up in place, additional, scattered showers and thunderstorms will continue to pop-up here and there this evening. Once again, though, NOT everyone will see this activity. Once the sun sets and temperatures begin to drop a little bit...the air will lose it's willingness to rise, so thunderstorm activity will slowly begin to subside by mid to late evening. Could there be a passing shower here or there? Yes...but the overall vigor and scale of rainfall will gradually decrease after sunset. A southeasterly wind may favor the eastern mountains to hang on to any rain the longest. Otherwise...it's a muggy evening with temperatures slowly falling into the upper 60s towards 10 PM to Midnight in many spots. Even with mostly cloudy skies...light winds and a pretty moist ground/lower atmosphere may allow for patchy fog development late. Overnight low's will fall into the low 60s by tomorrow morning.

Sunday will start with some patchy fog...but most of the morning looks dry for Church services under partly sunny to mostly cloudy skies. However, by the afternoon...the atmosphere will become unstable given rising temperatures and pretty high humidity (dewpoints in the 60s), so, like today, it won't take much to kick off showers and thunderstorms. In fact...with the stationary front interacting with a trough (upper-level disturbance) moving in from the west, showers and thunderstorms may be more widespread. While the weak upper-level winds will drastically reduce the chances for severe weather, slow-moving showers and thunderstorms may allow for a localized flooding threat...so that will be closely watched. A very moist atmosphere may also augment this potential threat. High temperatures will reach the upper 70s...but it will feel even warmer given the muggy air. Overnight Sunday into Monday morning...the deepest moisture and the weak disturbance will slowly slide eastward, allowing for a downward trend in rainfall. Monday morning will start with some valley fog, though, in the muggy low to mid 60s.

With the upper disturbance sliding east for Monday, there won't be much to initiate showers and thunderstorms...even with a strongly unstable atmosphere. With filtered sunshine and a slight bulge in the jet-stream...temperatures will soar into the upper 80s and dewpoints will be in the 60s, so a pretty sultry afternoon. Some leftover moisture may allow for a very spotty thundershower or two to develop in the afternoon, especially east, but most locations will remain dry given the lack of lifting mechanisms (fronts, low-pressures, disturbances, etc). The tropical-like airmass will hang tough for Tuesday, too; high temperatures will reach the upper 80s and humidity will stay elevated. Again...although the atmosphere will be pretty unstable, the lack of disturbances should preclude widespread precipitation. The only exception could possibly be north and west...where closer proximity to a warm-front may allow for some isolated showers & t'storms. Otherwise...it's muggy under partly cloudy skies. Wednesday will remain hot and muggy, too...but a nearing cold front will push scattered showers and thunderstorms towards the region by days end. High temperatures will reach about 90F under partly cloudy skies...so definitely a scorcher!

By Thursday...a slow-moving front, along with an upper-level disturbance, will move overhead. With plenty of moisture and an unstable atmosphere...numerous showers and thunderstorms look to form by the afternoon and evening. In fact...some storms could be strong given the increasing winds aloft (wind-shear), but a major episode is not expected. With mostly cloudy skies...temperatures will be cooler around 80F, but still muggy. Temperatures will drop as the wind turns out of the north on Friday...but a few showers will linger along the front as it drops southeastward. High temperatures will be cooler in the low to mid 70s under partly sunny skies...and the breeze will make it feel even more refreshing! The early call for next Saturday and Memorial Day weekend is a downright cool one! Although the pools open up...you may be looking for a hot-tub instead, especially at night! With a deepening trough (dip in the jet-stream) and a northwesterly flow...high temperatures will struggle to reach 70F for Saturday. The good news, however, is that it looks dry with a bit of sunshine. Overnight low's will tumble into the upper 40s to around 50F...so the summer mugginess doesn't look to be around to bring in the unofficial start to the season. A gradual warming trend may occur late Sunday into Memorial Day itself, though. Have a great evening, everyone...and take care!
