Light Snow This Morning

Light to moderate snow will continue for the next few hours across portions of Northeastern and Eastern Ok.  A Winter Weather Advisory will remain for Eastern Ok through the early afternoon hours.  Snowfall accumulations from 1 to 2 inches will be possible.  A few areas of southern OK may see a transition from snow to sleet to rain.  This system will be exiting the state this afternoon with warmer air quickly moving into the southern plains. 

This system is relatively weak and will not produce significant amounts of snow or sleet in the region due to a usual south wind with this storm.   Most of our surface winds during winter events are from the Northeast or East.  The model data suggested south winds for several days prior to the storm formation, and this is the case this morning.  The temperature profile aloft will keep the precipitation in the form of snow for most of northeastern OK, but a transition to sleet is a possibility by midmorning as warmer air begins to move northward in the lowest level  of the atmosphere.  The precipitation will more than likely be east of our area by the time the column would support rain later this afternoon or evening.  Model stop times have been anywhere from noon to 3pm, and observational data would support a stop time of near noon for the Tulsa metro, and then ending around 3pm across far eastern OK.  We will expect occasional snow bands for the morning hours with breaks in between the bands.   

While accumulations are expected to remain light, a few locations across Kay or Osage county could pick up some 2 to 4 inch snowfall amounts.  Some higher totals have been reported overnight from the southwestern OK and central OK areas.

Ground temperatures did come down during the past two days with the recent arctic air intrusion and this means some slick spots on bridges and overpasses will be possible. 

The upper air pattern will bring another system quickly into the region Tuesday night into Wednesday morning and model data supports some limited instability and energy.  This means a few thunderstorms may be possible Wednesday with highs in the mid-50s.  The higher chances for the storms may end up across the far eastern sections of the state into Arkansas, but I'll keep a healthy 50% pop on the board for this period and will mention the chance of a few storms.

The extended data supports another fast moving system brushing the state Friday, but very little precipitation will be possible with this system.  I'm inclined to leave the Friday period dry for today, but we may end up adding a 20% pop for a cover Friday. 

The temperatures tomorrow will move into the upper 40s near 50, with highs Wednesday anywhere from 55 to 60 degrees.  Temperatures will come back down Thursday to near normal levels with morning lows in the lower 30s and highs near 50. 

The weekend appears dry, sunny, and mild with morning lows near 30 and highs Saturday near 56 and Sunday near 61.
