Get out and enjoy the afternoon today because much colder air will be arriving this weekend and lasting for most of next week. I have gone slightly above the computer model guidance today based on yesterday's unseasonably warm readings in the lower 60s. We may see some lower 70s today across the southern part of the region while Tulsa tops out around 68 with gusty south wind at 10 to 25 mph. The fire danger will be elevated today due to extremely dry conditions and breezy wind.
The cold front will roll over the area around 3am to 6am tomorrow morning as strong north wind invades the state at 15 to 25 mph. We expect some sun tomorrow, but I do think eventually the clouds will win the day with afternoon highs in the mid to upper 40s across the northern part of the state with some lower 50s possible along the Red River. It will fill cooler. Big coat weather will be the call for the weekend and most of next week.
A strong surface ridge of high pressure will build down into the northern highs plains Monday centered near the North Dakota region. Very cold air will circulate around the ridge into the southern part of the nation keeping daytime highs in the upper 30s and overnight lows in the lower 20s.
A weak upper level system will slide down the central plains states Monday night or Tuesday morning creating enough lift in the atmosphere for some light snow flurries or brief snow showers. This is not expected to be a major system. Very little snow will fall if any at all.
The cold air will slowly moderate and shift eastward before another system arrives Saturday Dec 11th and Sunday Dec 12th. This one may also have some winter precipitation possibilities. Stay tuned.
