...Arctic Cold Front Will Usher in Much Colder Air for New Year Eve and New Year's Day with Much Colder Temperatures...
...Light Freezing Rain Possible over the Northern Brush Country and Extreme Northern Coastal Bend Monday Morning...
...Freeze Expected for South Texas Tuesday Morning and Hard Freeze Wednesday Morning Inland Areas...
Timing and Overview:
An Arctic air mass will surge into South Texas on New Year's Eve, providing strong and gusty north winds over the coastal areas. Wind chill values will fall into the lower to mid 20s by Monday morning as temperatures fall into the lower and mid 30s. A weak upper level disturbance moving out of Mexico will lead to areas of light precipitation over the region Sunday night through Monday. Temperatures are expected to fall to just below freezing over the northern portions of the Brush Country to near Goliad early Monday morning. There could be a light glaze of ice on trees, bridges, and overpasses due to light freezing rain. This will be possible in an area near and north of a line from near Columbia Bridge to Loma Alta, extending northeast to near George West to Goliad. Amounts are expected to be very light, mainly trace amounts with an area or two possibly receiving less than a couple of hundredths of an inch. Icing of roadways is not anticipated due to the warm ground temperatures, but some bridges and overpasses could have ice on them in the aforementioned area.
Precipitation chances will diminish Monday night. The Arctic air mass will continue to push into the region and freezing temperatures are expected area wide Tuesday morning. By this time however, the rainfall is expected to end or be offshore. Thus, at this time a wintry mix is not expected over South Texas Monday night, but if the moisture does not move out of inland areas by early Tuesday morning, then a wintry mix will be possible Monday night. Residents are encouraged to remain informed on the latest forecasts should rain chances continue into early Tuesday morning.
Clouds will diminish by Tuesday evening. With clearing skies, a hard freeze is anticipated for Wednesday morning with lows in the lower to mid 20s for South Texas, with near freezing temperatures near the immediate coastline.
Residents of South Texas should make preparations for protection of exposed pipes and sensitive plants with this upcoming cold snap to start the new year.
South Texas Impacts:
Expected Accumulations: Many trace amounts. Less than a few hundredths of an inch of ice could form on trees and elevated bridges and overpasses in a few locations.
Impacts: Travel could become dangerous over the northern Brush Country early Monday morning as ice could form on elevated bridges and overpasses. Cold temperatures along with dangerous wind chills could lead to frostbite and hypothermia if precautions are not taken Monday and Tuesday. Protect exposed pipes, sensitive plants and pets, and look on the elderly in these cold temperatures.
