What we know about Monday weather in Austin: Tornado watch in effect until midnight

Pack an umbrella, folks: Austin and Central Texas are expected to get its second but likely not its last dose of rain for the month on Monday.

"The combination of an upper-level low pressure system,

a cold front and remnant moisture from Hurricane Roslyn from the Eastern Pacific will lead to the possibility for isolated strong to severe storms mainly late Monday afternoon and Monday night," 

the National Weather Service said in a statement Monday morning. 

 "The primary hazard will be strong straight-line winds

, but hail up to an inch in diameter along with an isolated tornado may be possible as well."

8:30 p.m. update: A tornado watch is in effect until midnight for the Austin metro area, the National Weather Service said.
