HOUSTON (CW39) – Labor Day stays hot and humid across Southeast Texas with only isolated to scattered afternoon storms, mainly near and south of I-10.
Rain chances remain fairly low again Tuesday before deeper tropical moisture returns around midweek and brings a better chance for showers and thunderstorms.
Labor Day will be a little drier than the past several days.
Highs reach the low to mid 90s inland, with upper 80s to lower 90s along the coast.
Houston is forecast near 93 degrees.
Heat index values will climb to around 102 to 107 degrees.
A few showers and thunderstorms will develop along the sea breeze during the afternoon, mainly near and south of I-10. Most neighborhoods farther inland stay dry.
Even without a Heat Advisory, the combination of heat and humidity can still become dangerous during extended outdoor activities.
Tuesday brings another mostly hot and humid day.
Highs reach the mid to upper 90s inland, with Houston near 95 degrees. Heat index values could reach 103 to 108 degrees.
Rain chances remain fairly low, with isolated to scattered afternoon showers and storms again favoring areas near and south of I-10.
More tropical moisture returns Wednesday.
That should lead to a better chance for scattered thunderstorms, with rain chances around 50% in Houston.
With deeper moisture in place, some storms could produce locally heavy downpours capable of dropping a quick inch or two of rain.
Daily storm chances continue through the rest of the week.
Wet Bulb Globe Temperature values are expected to reach the upper 80s to lower 90s at times this week.
That means moderate to high heat stress remains possible, especially for people doing strenuous outdoor work or exercise for extended periods.
The Atlantic, Caribbean and Gulf are quiet, with no tropical development expected over the next seven days.
The bigger tropical story is in the Central Pacific.
Hurricane Lowell is a Category 3 hurricane with maximum sustained winds of 115 mph and is approaching the western Hawaiian Islands.
