Top 5 warmest Christmas on record possible this week

A significant December thaw is underway across mid-Missouri with temperatures soaring into the mid 50s with plenty of sunshine Saturday. Another day of mild weather is on tap Sunday.

A potent upper-level trough is expected to develop across the western United States this week. This will lead to strong southwesterly flow developing on top of mid-Missouri, pulling in warm air from the Pacific Ocean and Gulf of Mexico.

Temperatures will warm into the upper 50s and low 60s through Wednesday & Thursday. Localized locations in mid-Missouri may even get to the mid 60s.

Weather like this is very uncommon for December, especially on Christmas. If we get above 59 on Christmas Day, it will be the 6th warmest in recorded history. If the trough out west strengthens even further than currently forecast, temperatures on Christmas could flirt with the 5th warmest.

Don't worry. It's still winter. We're expecting the western trough to eventually translate eastward next weekend, leading to colder air and a chance at widespread rainfall.

At the moment, snow looks unlikely from that system.
