Extended Forecast: Friday through Wednesday:
Synopsis: The Seabreeze is bringing moisture further inland and allowing for some heat index temperatures to heat up to 110 degrees on Monday in parts of the Crossroads. Increasing dewpoints and Seabreeze moisture will push heat indices to 110 degrees and higher in the coming days. Heat advisory conditions did not last long enough to incite a warning, but Tuesday through Friday could warrant heat advisory conditions.
Increasing (low-level) moisture combined with warmer ambient temperatures should send heat indices into the 110 degree and hotter range. The dangerous heat levels are most likely for Kleberg, Jim Wells and Nueces Counties.
For the long-term period, Wednesday through Monday, the area stays hot and dry. A trough will develop out in the Gulf (not too far from the coast). The feature will move further east but then should head back (west) towards (and into) South Texas on Friday and Friday night. Due to the dry nature of our atmosphere, moisture levels should be too low to trigger any rain showers with this trough.
Heat advisories should be issued by Tuesday as temperatures get near 110 degrees at times in some spots. Wednesday will be a different story, as excessive heat warnings are a possibility as some portions of the viewing area approach 115-118 degrees with the heat indices for periods of time. Heat advisories could last through Friday and as winds pick up, and humidity levels drop, then elevated fire weather could be a concern as well.
High pressure will weaken by Sunday. The trough will not be strong enough to create enough lift for any significant if any rain at all. The Seabreeze will be the best chance at creating lift and rain over the weekend. Maybe squeezing out a shower or thunderstorm or two, but chances are staying at around 20 percent for now.
The continued heat, plus the dry fuels and as the winds pick up along with humidity levels dropping, then elevated fire weather could be a concern later in the week.
Tropical Weather Update: No tropical storm or hurricane activity is expected over the next 48-hours.
