A front will shift north to south across the area during the day on Saturday. As it does, expect storms to develop. Behind the front, cooler weather will take hold late Saturday and during the day Sunday. Here’s our latest thinking when it comes to rain chances:
SATURDAY 7AM-12PM: Mostly cloudy, stray shower or drizzle (30%)
An upper level low will push east toward Texas early next week. Only isolated activity is expected Monday, before rain chances rise again on Tuesday. We’ll be watching for strong to severe storms during the day on Tuesday. Rain will linger into Wednesday morning, before a quieter pattern takes over late next week.
