We're in the midst of a historical flood of the Highland Lakes, with a rise on Lake Travis of about 29 feet in only 36 hours, rivaling 6th place for the highest historical level. And it's still raining out there! You'll once again need an umbrella and a jacket today as our forecast keeps a 40% chance for showers & storms in the picture today, with temps rising back to low and possible middle 50s.
Fortunately, most of the new rain we see out there so far today has been light, yet every drop threatens to worsen the flood situation. Please be very cautious if/when traveling, especially in the Hill Country. More than 100 low water crossings are still reportedly closed according to atxfloods.com -- Turn Around, Don't Drown.
We've basically had the same atmospheric setup for three days, with a stationary area of low pressure over the southwest and a stream of Pacific moisture coming up from Mexico over Texas like a conveyor belt. It looks like the pattern will hold one or two more days before shifting.
In the meantime, Futurecast suggests a slug of moisture from the Gulf of Mexico will move into the area from the south and help generate a wave of showers & possible storms very late tonight through the first half of tomorrow. We'll bump the rain chance back up to 50% tonight then 60% for tomorrow/Thursday, then drop back to 50% odds on Friday. At the same time, temperatures will begin to warm up a bit more. I'm looking for daytime highs to return to the 60s as soon as Friday then get closer to 70 Saturday & Sunday.
Our latest models show possible 1/2" to 1" accumulations coming between now and Friday night, but most of the heavy stuff should be well north and west of the Austin area. The 7 day rain outlook from NOAA suggests some 2"-3" totals coming up.
