CORPUS CHRISTI, Texas — Extra wind, dry vegetation, lower afternoon humidity and scorching hot temperatures will result in some high to very high fire danger across South Texas today. Residents are encouraged to be especially careful when dealing with outdoor sparks and flames. Even mowing the lawn can cause an accidental spark and start a wind-driven wildfire.

In addition, we’ll get a thin layer of some of that dreaded Saharan Dust that will move back into our skies today and degrade our air quality a bit. The good news is that it is not forecast to be here long and should begin to clear out this weekend. Some more good news is that the dust is keeping the tropical Atlantic very quiet with no development forecast in the next 5-days.

Deepening low pressure, and associated frontal boundaries to our north, will keep winds elevated today. However, we’ll see slightly less gusty winds in the region. Still, we’ll see those sustained winds hovering around 15-30 MPH with afternoon highs still in the middle to upper 90s for many coastal locations and low 100s for our inland communities. With plenty of sunshine on tap, our heat indices will top around 106-112.

We’re keeping a close eye on a batch of moisture in the northern Gulf. As this pocket of instability rides around the belly of upper-level high pressure, it will move closer to our area late Friday, Saturday and into early Sunday. The result will be some isolated to scattered showers and storms in the forecast. Is this the drought-busting rain chance that we’re all looking for? No, it’s not. However, it’s our best chance of rain in some time. Heaviest rainfall totals will be near the coast where average amounts of .25-.50” will be possible, with lesser values inland. Under the spotty thunderstorm activity, wouldn’t be surprised to see some locally higher amounts.

By Sunday afternoon, the ridge, or dome, of high pressure builds back and the rainfall opportunity comes down. Aside from a few extra clouds and some afternoon seabreeze stray showers, the heat will continue to dominate heading into next week.
