We’ve needed some time to dry out in South Texas after all the rainfall we had over the weekend and that’s certainly been the case yesterday and again today. Sunshine has broken through a few clouds and afternoon highs have climbed above average in the low 90s. What makes the heat particularly unbearable, besides the mosquitoes, is that with all the humidity in the air the heat index numbers have also been on the high side. Out at Corpus Christi International, the heat index topped out at 109 degrees this afternoon.
We’re in for another muggy and mild night tonight with temperatures only falling into the upper 70s with light south-southeasterly winds around 4-8 miles per hour. This will lead to another round of some patchy fog, especially inland and in low-lying areas.
Wednesday will be very similar to today, but moisture will already be slowly on the rise. Cannot rule out a stray shower, but most will stay dry with highs in the upper 80s to low 90s. Winds: ESE 10-15 miles per hour
By Thursday, we’ll be watching several features. Moisture from the Gulf will be increase and a few disturbances from out west will also close in on South Texas. In addition, a weak frontal boundary will enter extreme northern sections of the state and be a focal point of rainfall activity. We’ll call for isolated showers here on Thursday with more clouds and still hot with highs in the upper 80s.
Friday and Saturday look to be the wettest as those disturbances out west move closer to the Coastal Bend. Some locations could pick up 1-3 inches of rainfall for both days. Highs will be pushed back near the mid-80s with the extra cloud coverage and because of the rain. Localized flooding will need to be monitored closely.
Rain chances do taper off beginning on Sunday and going into early next week. More sun will break through and highs will recover back into the upper 80s to low 90s.
A quick note, the National Hurricane Center has stopped monitoring the remnants of Isaac in the Caribbean. They’ve removed any opportunity for it to form into anything tropical, but as the moisture move west it could lend a hand in delivering us some additional showers on Friday and Saturday.
