Arctic blast to deliver ice, sleet, snow to San Antonio, Hill Country
A strong arctic air mass is headed in our direction and will bring a dramatic change in our weather pattern. We will likely experience significant winter impacts beginning early Tuesday morning and continuing throughout the day and into the late evening hours. The impacts will include a combination of ice, sleet and/or snow. The important point to focus on is that this will likely be a “prolonged” event with precipitation occurring throughout the day Tuesday.
Impacts will begin early Tuesday morning 3a-4a over the Hill Country and spread southward into Bexar county by 6am. The impacts will likely increase through the day and become more widespread. Travel will become dangerous with bridges, overpasses, flyovers and some roadways will be the focus points. Impacts will continue into the evening hours and carries the potential for an inch of snow across the Hill Country.
Ice accumulations of .10” may also present a problem for power lines as will the winds (25 to 30mph). Temperatures will hover near 30 with wind chill in the teens
