"Earlier this week I posted that the 7 day period starting Tuesday would be the coldest of the winter so far.Even though we had that brutal Arctic attack earlier in the month, the 7 day average was just 6.9 degrees below normal....still pretty impressive.After 4 days of my forecast of the coldest 7 day period, we are averaging 19 degrees below normal. It will ease some over the weekend and then get extreme again early next week.Here are some of the forecasts off the models.....GFS 2 week temperature forecast for Louisville starting today:\u00A0 22 degrees below normal the average for the 2 week period. That is ridiculous.GFS forecasts a low of colder than -15 one night during that period.GFS forecast for the first week of February: 20 degrees below normal.With all of that cold air, the ECMWF control has 1 inch of precipitation in that 2 week period with most of not all of it as snow.So while the temperatures may not end up quite as cold as the models say, they will still end up very cold over the next couple of weeks along with additional chances for snow. Eventually we are going to get out of the northwest to southeast clipper systems and into the storms forming over the south and moving northeast. If that change occurs while it is still cold here, then our snow is just beginning for the season. It certainly is something to watch out for.Be sure and check back to this blog for continuous winter updates. Thanks.Back in the late 1970's after a couple of cold winters, many scientists were talking about the coming ice age. It even made the cover of Time magazine. That was at the end of the cold phase of the Pacific Decadal Osciallation of which we are now in a cold phase again.
