Into the weekend, showers and thunderstorms will stay in the forecast. This should at least cut down the duration of the warmth during the afternoon hours.

Next 24 Hours: Any lingering showers and thunderstorms will continue to taper through the evening hours. After midnight, most of the area should be dry although muggy with low temperatures stopping around 70 degrees. As the workweek wraps up, partly sunny skies will guide high temperatures to about 88 degrees early in the afternoon. Shortly after, scattered showers and thunderstorms will develop and last until roughly nightfall before diminishing. All weekend long, any thunderstorms could produce briefly heavy rain, a lot of lightning and gusty winds.    

Up Next: Saturday will play out very similar to Friday with partly sunny skies giving way to scattered showers and thunderstorms during the afternoon hours. With slightly cooler air aloft and the onset of showers, high temperatures should be limited to the upper 80s. Though not entirely quiet, less action is expected Sunday. Early next week should get right back to a drier pattern with slightly above average high temperatures. There is a chance humidity could be a touch lower with dew points temperatures and low temperatures in the 60s. CLICK HERE for your detailed 7-Day Forecast.

LSU Baseball: While timing cannot be known exactly, the most favorable times for showers and thunderstorms will be 3pm – 8pm Friday through Sunday. Precipitation should be wrapping up around the start time of Friday’s game one against Ole Miss and then just getting started toward the end of games two and three on Saturday and Sunday. While some delays are possible, all three games should be able to finish. Certainly, the teams and fans will want to keep an eye on radar and have nearby shelter if lightning is around.

It has been a while since we talked about those rain chances, or percentages on the forecast board often seen during the warm season. Here is a quick reminder about what those mean for the WBRZ Weather 13 Parish, 3 County forecast area.

10-30% - Isolated: a few locations receive measurable rain

30-60% - Scattered: part to half of the area receives measurable rain

60-100% - Widespread: almost all of the area receives measurable rain 

Keep in mind, those chances tell nothing about timing. For instance, 100% DOES NOT mean it will rain all day. We will be sure to provide information in our forecasts as to when you can expect rain when chances are on the board. MORE: https://www.wbrz.com/news/a-chance-to-remember

The Explanation: An upper level low pressure system will move westward from the Atlantic Ocean into the Southeast U.S. over the next few days. At the same time, another upper level trough will move across the Plains and Great Lakes regions. These systems will weaken the subsidence caused by an upper level ridge that was responsible for the recent hot and dry stretch. Much more instability aloft will lead to convection (showers and thunderstorms). After quiet mornings, scattered activity will develop during the afternoon and evening hours through Sunday. With the ample instability and high moisture in place, any thunderstorms will be capable of downpours, frequent lightning and possibly some gusty wind. Sunday should work out to be the least busy of the three-day stretch as the upper level pattern transitions. The trough will start to flatten out and overall moisture will decrease into early next week. At the same time, an upper level ridge will try to reestablish over the region. The consequence of these changes will be fewer (if any) showers, warm temperatures and perhaps a slight reduction in dew points or humidity compared to the weekend.
