Muggy heat and a chance of rain may be possible in the Houston region for at least a day before a strong cold front pushes through.
A slow-moving upper-level disturbance is expected to linger above the region for much of Tuesday, sparking scattered showers and thunderstorms, according to the National Weather Service. Forecasters said some storms could be severe with heavy downpours. However, forecasters added, computer models are uncertain where the heaviest rainfall may hit.
A cold front is likely to arrive Thursday, briefly dropping temperatures about 10 to 15 degrees. The weekend probably will be mild and sunny.
On Tuesday, the high will be about 81 degrees under partly sunny skies. Southeast winds will be between about 10 mph and 15 mph. Fog may be possible before about 8 a.m. A 50 percent chance of showers and thunderstorms may be possible. Some spots may record up to an inch of rainfall, though it is difficult to determine where the heaviest rain may hit, said Josh Lichter, a meteorologist with the weather service.
"There's the potential for locally heavy rainfall," Lichter said.
Rain chances drop to about 30 percent at night. The overnight low will be near 66.
The area will probably dry out on Wednesday. The high will be about 84. A 20 percent chance of showers may be possible. The low will be near 65.
The Norther is expected to hit Thursday, Lichter said. A 40 percent chance of showers may be possible when the front arrives, bringing cooler air and breezy winds. The high will be about 76 degrees. North winds will be between 5 mph and 10 mph early in the day, increasing to 15 mph to 20 mph in the afternoon. Gusts could be as high as 25 mph. The overnight low will be about 49.
Cool air will probably linger in the area Friday. The high will be about 68 degrees under sunny skies. The low will be near 48.
A gradual warm-up is expected through the weekend. The highs Saturday and Sunday will be in the lower to upper 70s. The lows will be in the lower to upper 50s. No rain is forecast.
