Sunshine breaks through this afternoon; isolated rain still possible

TODAY

AUSTIN (KXAN) — After a cloudy and rain start, sunshine will break through the clouds again on Sunday afternoon, which will be perfect for folks outside enjoying Memorial Day. There will still be a small chance of pop-up showers and t-storms during the day, but it will be low, at 20%.

The Hill Country, as well as the western half of our metro counties, are under a “Marginal Risk” for potential severe storms later today/tonight. The main severe weather risk will be in the Hill Country, though it won’t take much new rainfall to trigger Flash Flood Warnings in the metro and eastern counties. Rain should be moving fast enough to avoid this threat, but it’s not a guarantee. Isolated overnight storms have the ability to become severe quickly, with winds gusting up to 70 mph and large hail. The tornado threat is overall low, but still present.

Keep the KXAN Weather App handy if you’re planning to be out on the water.

More than three inches of rain fell in far western Gillespie County in just a two-hour span Saturday evening, and more than two inches have fallen in far western Mason County.

River flooding continues for the Colorado River near La Grange. The river crested early Saturday morning and is continuing to fall closer to flood stage. It is expected to fall below flood state late Sunday afternoon. Other low water crossings remain flooded from Travis County to Lee and Fayette counties after the record-breaking rainfall late Thursday night and early Friday morning.

If you see water over a roadway, do not cross it. Turn Around, Don’t Drown.

Outside of drought periods, it is difficult to make it through an entire Memorial Day weekend without rain in Central Texas. Epic floods have occurred on this holiday weekend as late as last year, and in 1981.

Another storm system will approach after Memorial Day and will bring an increasing chance for rain and storms Tuesday through Thursday. Another 2-4 inches of rain could fall over the next 7 days across the KXAN viewing area.

Here’s the latest from the LCRA:

  • LCRA will resume full hydroelectric generation at Buchanan Dam at 6 p.m. Saturday, which will result in water flowing over the spillway downstream at Inks Dam beginning Saturday evening.
  • LCRA will resume full hydroelectric generation at Mansfield and Tom Miller dams Saturday morning.
  • LCRA will partially open one floodgate at Tom Miller Dam in Austin at 8 a.m. Sunday.
  • LCRA will partially open one floodgate at Buchanan Dam in Llano County at 9 a.m. Sunday.

LCRA encourages the public to be alert to local conditions and be prepared to take protective actions. When flash flooding occurs, avoid unnecessary travel. If you must travel, don’t drive into flooded roadways. Remember “Turn around, don’t drown.”

El Niño 

An El Niño pattern is diminishing in the Pacific Ocean, but may continue to influence our weather through the rest of spring, with above normal rainfall in the next week, before conditions dry out in the second week of June.

The Climate Prediction Center is forecasting the potential for normal rainfall during the June-July-August period as El Niño falls apart. Temperatures will likely be above average during this time.

A rapid shift to La Niña conditions are possible by late summer and early fall. La Niña conditions would bring drier conditions to Central Texas beginning this fall and lasting through the winter.
