Texoma should get its first widespread freeze of the season on Wednesday, November 13.
A large mass of arctic air moves southward from Canada early next week; all of the models show it blasting through the Red River Valley Tuesday. The map below shows the surface high in its projected Tuesday morning position:
Many outlying areas have already had a freeze, and Ada has also had one, but many locations such as Ardmore, Durant, Sherman-Denison and Gainesville have not.
The average first freeze dates for Texoma range from Nov 1 for Ada to Nov 14 for Paris, so this is a pretty typical event as we move into mid November.
Farther out in time, the models do not agree. One computer model’s (ECMWF) 10-day outlook shows a blast of very cold arctic air arriving around November 18, while another one (GFS) doesn’t show it all. So anything could happen…but it makes for an interesting weather time later in the month...
