Winter is Brewing
A very pleasant air mass will be in control of our weather over the next few days. Fantastic temperatures with most areas dropping into the upper 40s tonight and tomorrow night with a light Northeast Wind. With dry air in place and mostly sunny skies temperatures will warm into the upper 70s each afternoon this weekend. Cold air continues to develop in the northern latitudes of North America.Temperatures over the Greenland Ice Cap could dip to near 60 below zero over the weekend. The image above shows forecast surface temperatures at 1:00AM CDT. Notice a large area of dark blue and purple across the northern sections of the continent. This indicates a large area below freezing and some areas close to 0 degrees. The little spec of yellow, in the top center of the image surrounded by purple, shows temperatures between 60 and 65 below zero over the northern ice sheet of Greenland. This is the start of the foundation of cold air that will eventually move south across the United States. Of course, we will not see temperatures near that cold but, it is a sign that winter is not too far away.
