Our main issues will revolve around a developing upper level system that will bring winter weather threats into the state Friday into Saturday. Cold weather will remain today with highs in the upper 30s to lower 40s, yet we should see some clearing this morning with sunshine being dominate later today and tomorrow across northeastern Oklahoma. 

 

Tuesday temperature timeline.

 

Wednesday may be the best day of the week with morning lows in the 20s and afternoon highs reaching the lower to mid-50s before the first signals for incoming weather approach the state.

Thursday a surface cold front will pass the state bringing another surge of colder air across the northern third of Oklahoma with morning lows in the upper 30s and highs in the mid to upper 40s along with a few areas of either very light showers or some drizzle before the upper level system approaches and moves across the state Friday night into Saturday. This is a normal Oklahoma setup for a winter storm. The cold air arrives first, and the upper level system arrives 2nd

 

Timeline for rain, wintry mix.

 

While we still have some important features that could change precipitation types and amounts, the data is becoming more consistent suggesting the potential for winter weather impacts for at least the northern third of the state will be increasing during the Friday evening into Saturday period. Southern sections may still be mostly in the rain sector. We’ll continue to watch these important parameters and adjust accordingly as the data arrive.                                                                                                                                                             

At this point, we’ll offer a rather broad forecast of rain with some spotty freezing rain developing Friday midday to afternoon before transitioning to sleet-snow mixture Saturday morning with snow lasting through at least the morning to midday periods, if not longer into the early evening. The depth and magnitude of the cold air will determine this transition zone, times and amounts.

New data will arrive every few hours. We’ll update when appropriate.

Thanks for reading the Tuesday morning weather discussion and blog.

Have a super great day.
