The Winter weather advisory is no longer in effect for the Tulsa metro area. The advisory will remain through 3pm for portions of East Central OK.
Periods of rain will continue for the next few hours across eastern sections of the state with temperatures near or below freezing. This will result in periods of sleet and freezing rain which will lead to icing on elevated and exposed surfaces. No major travel issues are expected due to recent warm ground temperatures. But icing in trees will occur in some locations.
The system is expected to pass east of the area this afternoon with cold and windy conditions remaining.
The afternoon will be very cold with highs in the upper 30s or lower 40s later today but gusty north winds around 15 to 30 mph will create wind chill values in the teens. Big coat weather will be the call. Friday appears sunny but cold.
The air mass will modify into the weekend but not before producing Friday morning temperatures in the teens and lower 20s. I have Tulsa at a balmy 21 for tomorrow morning with afternoon highs in the mid to upper 40s. The weekend numbers look cold for the mornings and cool for chilly for the afternoons with Saturday highs in the mid 50s and Sundays highs in the upper 50s.
Monday another system will arrive with a chance of showers or even a snow flake or two depending upon the exact timing. GFS and ERU both now agree around a midday passage, but the overall chance of precipitation is extremely high.
The air mass will deepen behind the departing system with thickness values lowering into Tuesday midday. This leads me to drastically undercut the computer output and I'll start Tuesday in the upper 20s and place a high near 40 on the map.
Enjoy the Thanksgiving holiday, but please use a little caution through midday into the early afternoon period across eastern OK. If the precipitation indeed flares up there may be some minor issues in a few spots. I'll be here for most of the early morning to midday period and will update with any additional information.
