It seems like we're going to experience 3 seasons in one week, with fall showers and storms for Tuesday, spring-like temperatures in the 70s Wednesday & Thursday, then an Arctic Blast for the Christmas Weekend.
First up, a new upper-level low approaching Texas from the west.
This will increase drizzle and rain overnight, then showers and storms Tuesday morning. Along with the rain, another round of dense fog overnight through mid-morning Tuesday is likely.
A weak Pacific Front will move through the area Tuesday afternoon, allowing for a second chance of thunderstorms. A storm or two could be strong Tuesday afternoon, but mainly for areas east of Austin. Rainfall totals could approach one inch.
Behind this front will be drier and milder days, with highs in the 70s for Wednesday & Thursday.
A strong cold front arrives Friday, then a secondary, stronger front moves will move in Sunday morning. This will make for some very cold temperatures this weekend, including Christmas Eve and Christmas Day.
With highs only in the 30s, this may be the coldest Christmas since 1983.
The last 3 years have featured mainly above average temperatures for December 25, and since 2000, the coldest high temperature recorded was 45 degrees in 2000.
Forecast data shows that limited moisture will be available for the Christmas weekend, so snow, ice, and sleet will remain out of the forecast at this time.
