DISCUSSION
Issued at 142 AM CST Wed Dec 6 2023
Today and Thursday...Early morning satellite imagery with surface obs showed the surface high pressure ridge axis along the MN/WI border, with southerly winds beginning to develop across the region. These southerly winds were already warming temperatures a couple of degrees overnight, and this warmth will be the main story for the next few days. Dry conditions are expected, and temperatures aloft will support record highs on Thursday. The main question is how deeply will we mix during the day with the low sun angle, being we're only a couple weeks from the winter solstice. Forecast soundings are show rather shallow mixing, but they appear to be overdone in terms of boundary layer moisture. Given the lack of snow cover, did continue to adjust temperatures toward the high end of forecast guidance, with widespread 50s likely on Thursday, and 60s across western Minnesota.
Friday through Wednesday...A cold front will move through the region on Friday, bringing breezy westerly winds of 20 to 25 mph. Temperatures don't really cool off though until the secondary cold front moves through Friday night, and brings more northwest winds. In addition, models have trended with a slightly stronger upper level northern stream wave, and the combination of cold air advection with weak synoptic lift could lead to a few rain/snow showers on Saturday. For that reason, did add chances for precipitation above the blended forecast guidance. Any rain or snow that does fall will be very light, generally trace amounts. Looking ahead, this more seasonable, weather will stick around into next week, but temperatures will still be slightly above the average for mid-December with highs in the low 30s and lows in the teens to near 20.
