I apologize for the delay in getting the blog out this morning. I got a little extra sleep this morning after waking up at the crack of dawn for a weather conference this past weekend. We should be back to a normally timed schedule for the remainder of the week.

After a very warm Sunday thanks to south winds temperatures this morning are also a bit warmer. Warm-air advection has kept surface temperatures in the upper 40s to upper 50s along the Interstate 35 corridor from the Red River into South Texas. Some fog has developed this morning across the southeastern half of Texas. Locally dense fog is in place across the Hill Country into Deep South Texas. Any fog should burn off by 10 AM as temperatures begin their climb.

High temperatures for your Monday afternoon will generally be above-average once again. Folks along and south of Interstate 20 will climb into the 60s and 70s as south winds continue. The Rio Grande Valley will top out in the mid 80s this afternoon! A southward moving cold front will keep temperatures across the Texas Panhandle and South Plains in the upper 40s to upper 50s today. Temperatures may fall a bit as the day goes on.

A cold night is expected across the Panhandle into West Texas. Cold air advection behind the cold front will allow temperatures to drop off into the low to upper 20s. 30s are expected north of the Hill Country, Central Texas, and Northeast Texas. Southeast Texas and South-Central Texas will drop into the upper 40s. The Rio Grande Valley will only drop into the mid 60s tonight with dense fog a decent possibility. Much cooler temperatures are expected on Tuesday with 40s and 50s across most of Texas thanks to a cold front. Don’t fret warm-weather fans. Above-average temperatures return by mid-week.

Scattered showers are possible tonight and on Tuesday across Southeast Texas into the Coastal Plains. Severe weather is not expected. The heaviest rain totals up to one inch are expected across Far Southeast Texas. Amounts will decrease with westward progression. Scattered showers and perhaps a storm will be possible on Tuesday from Southeast Texas into the Rio Grande Valley. An isolated shower can’t be ruled out across South-Central Texas. Rain chances end by Wednesday.

SImulated weather model radar at 6 AM Tuesday

An area of light snow will move into the southwestern Panhandle and western South Plains early on Tuesday. At this time up to an inch of accumulation is possible on the Texas/New Mexico border. Any travel impacts should remain localized and well west of Interstate 27. A light rain/snow mix may occur across the Permian Basin and far western Concho Valley on Tuesday. Little to no snow accumulation is expected at this time.
