From Chief Meteorologist Alex Garcia
The weekend is here and the dogs of summer are barking loudly. High pressure has already moved into place and is sending afternoon peak temperatures into triple digits. The addition of tropical moisture into the region will result in Heat Index Values that will range from 102 to 106.
Rain opportunities through the weekend will generally be very low. Slightly better opportunities will work their way into the forecast Sunday evening out west and over the region Monday afternoon.
A much talked about “cold front” will enter the Texas Panhandle early Sunday morning and work its way south and eastward into North Central Texas. This is about as far as I believe it will get. Showers and storms will fire up along the frontal line and remain far to the north. The best we could hope for are surges of air (outflow boundaries) from collapsing storms to head southward into our part of the state and trigger some rain. The opportunity for this to happen is low but not out of the question. The additional cloud cover will help keep peak temperatures a few degrees cooler.
Saturday will start out with a mixture of clouds and sunshine. Temperatures will be in the upper 70s with a light south wind. High pressure will dominate the weather pattern. Look for clouds to evaporate out by mid morning. Temperatures will shoot up into the low 90s for the lunch hour. The afternoon will be summer-like with peak temperatures at or near 100. Heat Index Values will be near 104. Saturday evening will be very slow to cool with temperatures near 90 by mid-evening. Sunday will be an instant replay. The exception, we could see some showers fire up over the far western Hill Country.
Long range - forecast models are going in separate directions when it comes to rain and sunshine. The European model intensifies high pressure and that means a “hot and dry” week. The American model allows for the development of low pressure zone Thursday into Friday with slightly cooler temperatures and opportunities for rain. I’ll keep and eye on the next couple of model runs to see if there can be any agreement. For now, will play it down the middle and call for near normal temperatures with very low opportunities for rain.
