Freeze warning issued, but race weekend looking pretty goodNovember 12th, 2012 at 7:52 pm by Jim Spencer under Weather
The National Weather Service has issued the first freeze warning of the season for the Austin metro area, and most surrounding counties, including all of the Hill Country.
While many urban locations in the Austin area will remain above freezing early Tuesday morning, temperatures in the suburbs, coldest valleys and other low lying areas are expected to fall to 28-32 degrees before sunrise.
Most locations in the Hill Country will likely experience at least a light freeze. The low lying areas in counties east of IH-35 could also experience a brief, light freeze.
The freeze warning includes all of the KXAN viewing area except Caldwell and Fayette counties.
The anticipated freeze is right on schedule, as the average first freeze in the Hill Country is during the second week of November.
However, it will be an early freeze if the temperature falls to 32 at Austin-Bergstrom International Airport, where the average first freeze is Nov. 27. In Austin, Camp Mabry’s average first freeze doesn’t occur until Dec. 2.
Area residents in locations where freezing temperatures occur early Tuesday should be aware that sensitive plants and tender vegetation may be killed. Covering those plants or bringing them indoors may be necessary.
Mornings will be chilly all week, though Tuesday morning is expected to be the coldest. Afternoons will remain cooler than average, with highs only in the 60s through mid-week.
Fortunately, for race fans and anyone who’ll be outside over the weekend, warmer weather is expected for the coming Formula One festivities. High temperatures will return to the 70s by Thursday, then remain very pleasant through Sunday.
Morning will still be a bit cool, but near November normals–in the upper 40s to low 50s.
Probably the best news for Austin’s inaugural F1 event is the decreased chance for rainfall. Last week, computer models indicated the possibility of a wet weather system moving across Texas this weekend.
But now they have backed off that scenario. There now appears to be only a slight chance for showers on Sunday.
Here are the Freeze Warnings in effect for the KXAN viewing area:
