Cloud cover will be on the increase today across the Rio Grande Valley, South Texas, the Coastal Plains, and Southeast Texas. The increased cloud cover will be accompanied by muggy conditions.

Temperatures this afternoon will still be quite warm across those regions – even with mostly cloudy skies. Skies are expected to remain mostly clear to partly cloudy north of Interstate 10 for most of today. Temperatures will range from the lower 80s in the Hill Country and Central Texas to the upper 60s in the Texas Panhandle. Winds will be out of the south in locations south of Highway 80 today. The Texas Panhandle, South Plains, Rolling Plains will be out of the north/northwest.

Relative humidity values will drop into the teens across the Texas Panhandle and West Texas this afternoon. The fire weather meteorologists have highlighted an elevated wildfire risk across those areas. Wind direction will be out of the northwest with speeds up to 20 MPH.

Cloud cover will spread north tonight into Central Texas and East Texas. Areas of fog are also expected – especially closer to the coast where moisture levels will be higher. The Rio Grande Valley won’t get below 72-73 degrees tonight so fog is likely. South-Central Texas, the Coastal Plains, and Southeast Texas will be in the 60s tonight. By the time you get north to Interstate 20 temperatures will be cooler since moisture levels will be lower. The Panhandle will drop off into the 30s by sunrise Thursday.

An isolated shower will be possible tonight across North Texas, Central Texas, South Texas, and Southeast Texas. Any shower/storm that develops should be isolated and produce relatively light rain totals. Severe weather and flash flooding are not expected. Scattered showers and storms will be possible on Thursday across the eastern half of Texas. Localized rain totals up to one half inch are possible. Flash flooding is not likely since rain totals should remain low enough. A strong storm with small hail is possible.
