Heat and Holiday Storms: What to Expect This Memorial Day Weekend in Houston

Houstonians who want to do things outside over the Memorial Day weekend should be ready for a summer-like mix of sun, heat, and rain here and there. High temperatures are expected to hit the low to mid-90s, and the heat index will be above 100 degrees. There is a 20% chance of storms on Saturday and Sunday, but the chance of rain on Monday rises to 40% as a weak front moves toward Southeast Texas.

Even though there is a chance of storms, the weekend should be mostly warm and dry, especially in the afternoon. People should drink water, wear light clothes, and look for shade or air conditioning whenever possible. In the mid-70s, the mornings will be warm and muggy, and there may be fog patches before sunrise.

After the holiday, storms are more likely to happen. There is a 60% chance of rain on Tuesday, and temperatures will drop to the 80s shortly.

Forecasters are also looking ahead to June 1, the start of storm season. NOAA and Colorado State University say the season will be above average because the Gulf waters are warmer than usual and there aren't any strong El Niño or La Niña conditions. Named storms will number 13 to 19, hurricanes will number 6 to 10, and major hurricanes will number 3 to 5.

Plan ahead to beat the heat, whether going to the beach, a funeral service, or just relaxing outside. Also, keep an eye on the weather.
