As of the noon update, the temperature in Austin at both Camp Mabry and the airport has soared to 73°F...a significantly colder air mass is sitting just to our north as evidenced by temperatures in the 40s and 50s from Waco north. That cooler air mass will slowly continue to sag south into our area this afternoon into the overnight hours allowing temperatures to drop back down into the 40s/50s tonight under partly clear skies.
Noon Surface Temperature Analysis:
Warm front surges north through the area on Friday in response to a strong storm system crossing the center of the country that will open the door for a strong Arctic cold front to blast through the area late Saturday. Highs ahead of the Arctic Front on Friday and Saturday will climb into the 70s on breezy/gusty southerly winds. There will be a slight chance for showers and thunderstorms along and ahead of the Arctic Front Saturday afternoon/evening (especially for areas along and east of the IH-35 corridor).
Saturday's Arctic Blast:
Folks, this front is going to mean business. It will drop highs on Saturday from the 70s into the 30s/40s for Sunday on a strong and gusty north wind. This cold air is not just stopping by for a day, it will be with us through the middle of Christmas week. At this point in time, wintry precipitation does NOT look to be a concern, but widespread freezing temperatures and potentially dangerous wind chills are likely to be. I believe all of central Texas needs to prepare for at least one if not two hard freezes by Sunday and/or Monday. Temperature trends will continue to be monitored in the coming days and more updates will be coming.
