Still On The Way!

Even though we are not at the center of the target we are still in the range of that dreaded arctic air. Here in northern Indiana we will be just on the edge of the coldest air. Take a look at this graphic representation
You will see that red color I've been pointing out over the past couple of days. This graphic represents 850 mb which is slightly above the surface. Temperatures will be -24 Celsius or -11 below Fahrenheit by Sunday morning. So here's what I expect will happen. The polar front will move in late this evening and temperatures will begin to plummet. We will begin tomorrow with temperatures in the lower teens but highs will quickly fall from there. The coldest air will be sitting across our area Sunday morning. Temperatures will slowly moderate Monday but It think there is another chunk of the 'polar vortex' that is apparent on this graphic which is the 850 mb from the European model for next Thursday. You'll notice that the intense red color representing the -26 Celsius line. So get ready for what is shaping up to be the coldest week of the Winter season.
