Sunnier, warmer Tuesday; blast of cold air arrives Wednesday

Temperatures will struggle to get out of 40s by week's end


SAN ANTONIO – After a chilly and wet weekend, the upper-level storm system responsible for all the rain is moving overhead Monday and will eventually push northeast and effectively end the rain chances.

Rainfall totals were on the hefty side. Seventy-two-hour accumulations show some areas of South Texas getting 4-8 inches, with an average of about 3-5 inches. Officially at San Antonio International Airport, the three-day total was 5.79 inches. We’ll continue to hold on to above-normal precipitation for the year with just about 43.50 inches of rainfall that has fallen since January.

As the disturbance exits Monday evening, the skies will begin to clear from west to east. Tuesday will be a great day for outdoor activities as highs get back to near normal in the upper 60s with an abundance of sunshine.

Don’t put the jackets and blankets away, however. Wednesday will be a transitional day as a surge of arctic air will push through the southern Plains and arrive in South Texas during the late evening and overnight hours. Winds will increase from the north-northeast around 15-25 mph with gusts as high as 30-35 mph. There is a small opportunity for some rainfall along the boundary, but most should remain north and then pick up again as the front moves toward the coastline. 

Highs on Thursday and Friday will struggle to get out of the upper 40s, under partly to mostly cloudy skies. The area could also see widespread freezing temperatures by Friday morning. Those with sensitive vegetation, it would be a good idea to protect them. Also, be sure that outdoor pets have a good place to keep warm.

Next weekend, the colder air will modify and temperatures will get back into the 50s and 60s under partly cloudy skies.
