Happy Hump Day for this short week...
Increasing clouds today everywhere east of Big Bend. Stronger southeasterly flow has brought in higher humidifies and kept the overnight temperature a little more reasonable (in my book, but I'm a wimp when it comes to cold). High temperatures should be a few degrees warmer than yesterday.
The big topic to speak of is the approaching weather system that will be impacting the region Wednesday Night through Sunday Morning. We've had a scenario like this recently, where a cold front, strong moisture from the Gulf of Mexico, and significant moisture from a Tropical Storm in Mexico all collide over Central Texas. That's the case again, and parts of Central and North Texas could see up to 10 inches of rain (although that looks to be worst-case scenario is isolated pockets). Widespread rainfall, however, will total 3-5 inches through much of Hill Country and the Interstate 35 Corridor, and 4-6 inches along and north of the Interstate 20 from Abilene -East. Further south...Big Bend area, Del Rio, Eagle Pass, Cotulla, Laredo...probably 1-2 inches through the time period.
West Texas will begin to see rain showers coming up from the southwest Wednesday evening...most of the Central Texas region won't really experience anything really significant until about Friday Morning. Heaviest rainfall will fall with the cold front....but the cold front will stall over Central Texas and become stationary....leading to up to 48 hours (Friday mid-day through Sunday morning) of moderate rainfall over parts of Hill Country and North Texas.
(Read my article on stalling cold fronts here)
The obvious hazard associated with heavy rainfall is flooding...so if you plan on travelling anywhere for the long weekend, be VERY careful and stay out of low-lying areas. Make sure you have plenty of gasoline in case you need to detour, and keep a charged cell phone.
Stay tuned for updates!
