Cold Air All Week Across Northeast Oklahoma

Good Christmas morning to you and your family.   The cold air is here for a while and will be reinforced a couple of times this week with at least two fronts, possibly three, that will move across the state.  One boundary slides southward sometime early Tuesday morning with gusty north winds and another system will be clipping the state Thursday night into Friday.   After this Thursday system, much colder air will continue to flow southward into the state through the weekend.

The upper level support for a possible system Thursday remains very weak but there may be a few sleet or snow showers Thursday across far northeast Oklahoma and southeast Kansas yet no accumulation will be in the current forecast.   A stronger surge of colder air will arrive this weekend with the potential for some very cold arctic air sliding across the state setting the stage for some light wintry precipitation Saturday into Sunday.   Model data is not consistent with certain important features.   The EURO is mostly dry this weekend with the GFS more robust with some light wintry precip.   Until the data becomes more certain (increasing forecast confidence) we’ll stick with our current low probabilities for this weekend.

Wind chill values will be very noticeable for the next few days, more so during the late night and early morning hours.   Values Tuesday morning may drop into the single digits for a few spots across northeast Oklahoma.
