CHANGES FRIDAY/THIS WEEKEND
A cold front will move through Friday evening. There’s no set hour for when the cold front will move in Friday evening, just expect the shift sometime after sunset.
It’ll kick up the winds and drop temperatures a bit over the weekend. The exact strength of the front is still uncertain, so check back for updates.
Friday night cold front, not as warm this weekend. (Copyright 2024 by KSAT - All rights reserved.)
EL NIÑO UPDATE
An El Niño watch has been issued. What does that mean? Not much for now. But it is worth noting that a switch from La Niña to neutral is underway (La Nina has been in place 5 out of the last 6 winters). By the summer, we will make the switch to El Niño. Any affects to the pattern would likely hold off until winter. Could this mean more rain for us? Yes, but it’s not a guarantee. El Niño years typically bring a more active pattern.
