Here is the very latest weather update concerning the upper level low that will move through the area late tonight and early tomorrow morning. This is our "PRECISIONCAST" weather model for 6:00 am Friday morning. Notice that all of eastern Oklahoma and western Arkansas has a very good chance of waking up with either rain or a wintry mix. Right now, it looks like south of I-40 will be mostly rain chances. North of I-40 looks to be where the freezing line will be, in the upper levels of the atmosphere. This is the part of the system where the rain will try to turn over to snow. It's represented by the pink shading you see on the image. This is where sleet could possibly take place, but I am going to hold off on the chance of freezing rain in the forecast for right now. In order to get freezing rain, you need warm air aloft and freezing temperatures at the surface. We are forecasting morning lows to be above freezing for the entire viewing region and our air looks to be cold aloft. The heavier snow accumulations will be well to the north. "Snow Advisories" have been issued for all Oklahoma counties along the Kansas border. The good news about having temperatures above the freezing mark (32°F/0°C) at the ground level is that it should prevent snow accumulation on roads and bridges.
