SAN ANTONIO – On the heels of a cold front that moved through the Alamo City Monday afternoon is another shot of cool air. Dew points went from the 60s to the 30s and 40s and will make the air feel much cooler in the mornings beginning Tuesday.
We missed the rainfall associated with Monday’s front, and were left with a few high cirrus clouds and highs in the low 80s early before the front came through.
Monday night, the skies are forecast to remain mostly clear to partly cloudy and temperatures will fall into the upper 40s. Those in the Hill Country could see that temperature in the low 40s to upper 30s.
On Tuesday, another cold front -- Pacific in nature and more like a secondary surge of cooler air -- will move through San Antonio around sunset. This will allow temperatures to remain mild for most of the day with highs in the upper 70s to low 80s under partly cloudy to mostly sunny skies.
Wednesday and Thursday look sensational for all outdoor activities, with mostly sunny skies and highs in the upper 60s. Morning lows will fall in the upper 30s to lower 40s. The kids will need a jacket for the early morning.
The forecast becomes a bit more complicated by Friday and going into the weekend. A large upper-level disturbance will ride down the Rocky Mountains and has the potential to bring the area some significant rain on Friday and into early next week.
This scenario is being drawn out by the American Global Forecast System model, which takes the low into northern Mexico and puts Texas in a prime location for moisture and rainfall. The European forecast model, however, is less progressive and takes the low into the Texas Panhandle and will bring us some rainfall early Saturday, but otherwise dry for the rest of the weekend.
One thing is certain: The cooler and more seasonal temperatures will make their way into our region by late this week.
We’ll be keeping a close eye on the forecast for the next several days as forecast models become better aligned and fall into closer agreement. If you have weekend plans, it will be a good idea to watch the seven-day forecast for the next several days, as it may change drastically from one day to the next.
