Very dense fog is occuring this morning on the south side of a cool front near the coast. Some of the fog is the ‘so dense it causes a 70 car pileup’. It should burn off by 9-10 AM, but until then use extreme caution while driving. The cool front (more of a dry front honestly) will move east/south through the day. Conditions north/west of the front are much drier, albit not much cooler. A couple of severe storms may develop by mid-afternoon in far East Texas. These storms could fire up in a hurry with a threat of large hail, damaging wind gusts, and an increasing tornado threat once they move into Louisiana and Mississippi. We might scrape by and have the storms form just east of Texas, but that possibility isn’t guaranteed. Our severe storm chances end by dinner-time in Texas, but will only be starting up to our east.
Record high temperatures in the middle 90s are forecast in the Rio Grande Valley today. McAllen made it up to 99 degrees yesterday which shattered the previous record high of 87 degrees set back in the mid 2000s. The remainder of Texas will top out in the upper 40s in the Texas Panhandle to 70s along Interstate 35. Peak temperatures will be on a slow decline through the week as cooler air filters in from the north. A major cool down will occur on Saturday with high temperatures in the upper 30s to lower 50s all the way south to Interstate 10. Only the Rio Grande Valley will remain somewhat warm with 70s on Saturday. Make no mistake about it – Saturday is going to feel like a December winter day.
Rain chances start increasing on Friday for some and by Friday Night and Saturday will include all of Texas. In fact there is a good chance that nearly everyone in Texas will see rain over this upcoming weekend. The much cooler air mass on Saturday will be shallow. Above that will be warm and moist air with widespread precipitation forming thanks in part to that process. Severe weather is not expected nor is a winter weather event. There may be some rain/snow mix in the Texas Panhandle and West Texas at points this weekend, but minimal accumulations/impacts are projected currently. A general expectation of 0.50 to 2 inches of rain can be expected in the Friday-Sunday timeframe across Texas with local amounts varying. Southeast Texas has the potential of receiving 2 to 5 inches of rain with localized flooding a possibility.
