HUMIDITY: Returns Wednesday evening
SMALL RAIN CHANCE: Late Wednesday and again Thursday
MEMORIAL DAY WEEKEND: Warm with a slight chance for storms - mainly late Monday
FORECAST
LOWER HUMIDITY
In the wake of a weak front, the humidity has been pushed along the Gulf Coast, but it’ll surge back into place tomorrow evening. Then it’s here to stay.
SMALL RAIN CHANCES
A return of moisture and a small storm system arriving from Mexico means we could see a few storms flare up Wednesday night and again Thursday, but the odds are low (20%). Better rain chances are in deep south Texas. Temperatures will remain toasty, reaching the mid to upper-90s each day this week.
EARLY MEMORIAL DAY SNEAK PEEK
As we honor the men and women who have made the ultimate sacrifice, know that a few strong storms are possible especially later in the day and into Monday night. Early indications are that we may see a front that could stir up activity. It may also cool us down. There will be updates to this forecast, so make sure and check back.
