If you thought it was chilly this weekend, wait until you see what's in store for us on Monday. An arctic air mass is moving quickly into the southern Plains and is expected to push into Central Texas late tonight and Monday morning.

A powerful upper-level system will generate widespread rain and embedded thunderstorms across our area tonight and into the morning. Our severe weather threat is low, but locally heavy rain and lightning is anticipated in some locations. Our wind will turn back out of the north just before sunrise, and temperatures will begin to crash across the region. The majority of Central Texas will only make it into the 40s and low 50s by sunrise. By daybreak, temperatures are expected to plummet.

Most of the rain will shift east by the early/mid afternoon, although a few showers will linger into the early evening. Our winds will REALLY pick up by the afternoon. Wind speeds will range anywhere between 25 to 35 mph. With temperatures crashing into the 40s and 30s, wind chills will likely drop into the 30s and 20s. It’s going to be a miserable day to be outdoors (which is the reason why a lot of the Veterans Day parades were canceled). If you have any plans to be outside, be sure to bundle up. We’re expecting our first freeze to occur Monday night into Tuesday morning, with overnight temperatures falling into the upper 20s and low 30s. Now is the time to review the 4 P’s: People, Pets, Plants and Pipes.

Wind speeds will still be somewhat elevated heading into Tuesday, so morning wind chills could be in the 20s and upper teens in some locations. With abundant sunshine on Tuesday, highs should make it into the 40s. However, it will be extremely dry outside. Clear skies, light winds and dry air will promote COLD conditions Tuesday night. By Wednesday morning, most of Central Texas will be in the 20s. Yes, we’re expecting two straight nights of sub-freezing temperatures, with a hard freeze likely by Wednesday morning.

A slow warm-up should take place the rest of the week, and temperatures should return to near-normal by next week.

Get ready, Central Texas! Winter is coming.
