SAN ANTONIO – There was certainly a bit of a chill Tuesday morning as temperatures fell into the upper 40s here in San Antonio and even into upper 30s around Kerrville, Fredericksburg and Junction. They quickly rose to above-normal levels Monday afternoon as highs are ranging from the mid- to upper 70s and even some low 80s under plenty of sunshine.
Be sure to grab the jackets early in the morning because another shot of reinforcing cool air will make it into Central Texas Tuesday night and early Wednesday morning. With clear skies and relatively light winds, we’ll see morning lows dip into the mid-40s. The Hill Country will again see some upper 30s to lower 40s. By the afternoon, temperatures will be cooler than on previous days, but right at seasonal averages, in the upper 60s to low 70s.
Thursday will also be a nice day with plenty of sunshine and a few more clouds, with average highs. Take note though: Temperatures in the morning may flirt with the freezing point in the Hill Country, but most locations should fall into the mid to upper 30s. Those with sensitive plants or vegetation may want to cover them to protect them from the colder temperatures.
Friday is when things get interesting and the weather does a complete turnaround. Clouds will quickly increase and a few scattered showers will begin to fall.
An upper-level storm system will move in from the west. It will throw plenty of moisture into Texas and create a widespread rain event by Saturday and into Sunday.
Since surface winds will be out of the north, an overrunning pattern will evolve with cloudy, dreary, cold and wet conditions taking over. Highs will only reach the mid-50s and lows will be in the upper 40s to low 50s.
Rainfall amounts will not be heavy. Widespread amounts of up to an inch will be common, but some isolated locations could reach 1 1/2 inches of rain.
This system will depart by Monday, with rain slowly coming to an end. High temperatures will recuperate to more seasonal levels, the upper 60s, on Tuesday, with partly cloudy skies.
