A look at cold front set to hit Monday night

Fall in San Antonio is known for its up-and-down weather, and it’s certainly been that way the last couple months. Another cold front is heading toward South Texas on Monday night, and it will produce roller-coaster temperatures. Let’s take a look at the timing and exactly how cold it will get.

Monday’s timeline Morning (4-9 a.m.):

It will be mild and muggy to start the day. Low temperatures will be in the mid-60s, which is about 15 degrees above average for this time of year. Thanks to ample moisture in the atmosphere, patchy fog will be possible, especially in the Hill Country.

Midday (10 a.m. to 4 p.m.):

Temperatures will reach 70 degrees just after 10 a.m., on their way to the upper 70s by afternoon. We won’t come close to the daily record of 85 degrees, but in a few spots temperatures could touch the 80-degree mark.

Partly sunny skies are expected during the afternoon, and there could be isolated showers and storms in South-central Texas. However, overall rain chances will be very low in San Antonio: just 10% to 20%. The chance of rain will be higher to the east.

Evening and night: (5 p.m. to midnight):

The cold front will start to come through around sunset. Wind will change direction and start moving into San Antonio from the northwest. It will be gradual at first, but winds will become stronger late at night, hitting 20-25 mph after 9 p.m. Temperatures will fall to the 60s after sunset and into the 50s overnight.

The rest of the week

Behind the cold front, belowaverage temperatures are expected for the rest of the week. By Tuesday, highs will be in the low to mid-60s under mostly sunny skies. Winds will be about 20 mph for much of the day. Some morning gusts could rise above 30 mph.

Cold air will continue to filter in overnight and into Wednesday. Lows will drop into the mid-40s to start the day, and highs will be 62 to 63 degrees. That is 5 to 10 degrees below average for late November. Not a drop of rain is expected across the state, making for favorable travel conditions if you’ll be on the road ahead of Thanksgiving.

It’s going to be hard to complain about the weather on Thanksgiving Day in South Texas. After a chilly morning with temps in the 40s, highs will reach 64 to 68 degrees in San Antonio. Add sunny skies and a light wind at 5 to 10 mph, and you get a picture-perfect Thanksgiving.
