Weather Blog: Chilly Next Couple of Days

News

The initial surge of cold air that arrived yesterday morning resulting in a chilly start this morning, but will see increasing downslope winds much of the day with nearly full sun.

This will modify the existing cold airmass enough for temperatures to warm back to near normal levels this afternoon, especially over eastern Oklahoma. Meantime, a bitterly cold arctic airmass is being driven south into the northern Plains and will result in absolutely brutal conditions to our northeast the next couple of days.

While the pattern favors only a glancing blow from this airmass into western Arkansas and at least parts of eastern Oklahoma, there will be about a 24-36 hour period of very cold weather with wind chills likely dipping a few degrees below zero across parts of northwest Arkansas and extreme northeast Oklahoma late tonight Wednesday morning.

The front will likely stall somewhere over southeast Oklahoma and while temps will warm back into the upper 40s near the Red River, they will struggle to reach low-mid 20s along Missouri and Kansas borders.

The deep polar low over the Great Lakes will quickly shift east allowing for quick modification of the shallow cold air beginning in some places as early as Wednesday night and area-wide by Thursday.

The cold will be a distant memory by the end of the week as the upper air pattern becomes more zonal and eventually features a deepening southwest flow. A weakening southern stream wave will pass by to the south Friday night and Saturday, with enough moisture present by the to bring a chance of rain to
southern areas.

Much above normal temperatures expected by Saturday and especially Sunday. A frontal boundary may move south into the area by Monday and at least knock temperatures back to more seasonable levels early next week along with a chance of showers.
