We finally got the opportunity to dry out in South Texas giving the grounds an opportunity to soak up all the rainfall that we’ve had over the last 72-hours.  There were, however; a few little stray thundershowers that ignited with the afternoon seabreeze and pushed inland.  Though the coastline missed out, what did pop up dropped another round of some hefty rains for those who experienced the rainfall.

Tonight we’ll be under partly cloudy skies with some more patchy fog forming for our inland areas and in locations that are low-lying.  Overnight lows will drop into the middle 70s with light south-southeasterly winds around 4-8 miles per hour.

Tuesday and Wednesday we’ll have more opportunities to dry out, but it will be prime territory for mosquitoes because it will be very muggy and hot. Afternoon highs will shoot up in the low 90s with heat indices in the 100-110 degree range under mainly sunny to partly cloudy skies.

On Thursday the moisture will begin to increase as upper-level high pressure moves to the southeastern United States.  This will give us return flow off the Gulf of Mexico and slowly begin to increase the rain chances.

We are monitoring the remnants of Isaac in the Caribbean.  The National Hurricane Center has a low (10%) chance of development in the next 5 days as it moves west.  It will encounter plenty of wind shear and be in an environment that is not conducive for development.  Still, it will stay on our radar and may actually contribute to rainfall chances heading into Friday and Saturday as scattered thundershowers return the forecast in the Coastal Bend.

As with any tropical showers, heavy downpours and localized flooding will be an issue that we need to monitor.

By Sunday and Monday the moisture will start to back off and we’ll reduce rain chances to just isolated.  By then, sun will break through the clouds and we’ll return to damp, humid, and hot conditions.
