SUNDAY
Noticeably more humid than Saturday. Mostly cloudy with some peeks of sunshine in the afternoon. Near 90°. There is a small chance for a shower or storm in the evening, but the chance is only 20%.
NEXT WEEK
Our weather pattern next week will be unsettled. Rounds of energy and a slow-moving cool front will keep storms in the forecast daily, mainly starting Tuesday night through the weekend. Timing and placement of storms is difficult to know at this point, but wherever storms set up, we’ll have the ingredients for strong or severe storms AND storms capable of street flooding. This unsettled pattern looks to last through Memorial Day Weekend, too.
