STORMS LIKELY WITH COLD FRONT TONIGHT
A cold front and associated low pressure system are making quick Northwest-to-Southeast movement through Northwest Texas and Oklahoma this evening. The front will move through Central Texas between 3 AM and 8 AM Sunday Morning.
SEVERE THREAT: Thankfully, with this front moving through the pre-dawn hours Sunday, there won’t be much energy for this front to work with, so a widespread threat for severe weather is not anticipated. Still, a line of thunderstorms moving through will bring the potential for some gusty winds, which could briefly top 60 MPH. Some small hail may accompany the stronger storms, especially for areas north and west of Austin. Tornado and flooding concerns are VERY LOW.
SUNNY AND COOLER ON SUNDAY
After the quick early-morning storm chance, skies will rapidly clear by late Sunday morning and the rest of the weekend will look and feel fantastic. Highs Sunday will top off in the upper 70s with abundant sunshine and gusty north winds.
ONE… NO, TWO MORE COLD FRONTS
After a warm(er) Monday, another front will move through Tuesday. It’s a grazing blow in terms of a cool-down, keeping highs in the 70s and lows in the 50s locked in through Wednesday. But wait… there’s more!
POTENTIAL ARCTIC FRONT NEXT WEEKEND
Roughly one week from now, a potent, arctic cold front will take aim at Texas. Timing and intensity will need fine-tuning over the next week, but early indications are that temperatures will drop a full 20-25 degrees, with highs by Halloween weekend topping off in the mid 50s… Overnight lows could dip into the 30s for the first time since late January. Still on the fence about costume ideas? Eskimo is looking like the utilitarian option.
Tropics are quiet as a mouse. No new tropical development is expected over the next five days in both the Atlantic and Pacific oceans.
