A big warmup is expected across the southern tier of the country this week.
After just a week into December, it has been one of the warmest starts to the month for most of the country. Average temperature departures of 20-30 degrees stretch from border-to-border and 28 separate states. That's enough to be a top 10 record warm start to December for hundreds of locations.
By Friday, numerous record highs will be in jeopardy across the Southern Plains and lower Mississippi Valley as temperatures soar into the 80s.
For some, it'll be downright hot as temperatures soar to nearly 25 degrees above average, the National Weather Service in Fort Worth, Texas, said. Temperatures will be on the rise, with 80-plus-degree highs forecast Thursday and Friday. Dallas/Fort Worth and Waco's high-temperature records are also in jeopardy of being broken.
Dallas/Fort Worth's record highs are 79 and 84 degrees for Thursday and Friday, and the current forecast calls for 80 and 83 degrees, respectively, the NWS said. Waco's record highs are 82 and 80 degrees, with forecast highs of 82 and 84 degrees for the same days.
The heat passes Friday night and Saturday as the next strong cold front pushes southward through the region.
