Good Tuesday, folks. Colder than normal air has pushed back into the bluegrass state and that’s been a common theme of the past month or so. Our pattern shows NO signs of going into anything that resembles true springtime weather in Kentucky. If anything, we have a shot at pulling out a top ten coldest March on record.<\/p>\n

This is especially true given the tremendous amount of blocking showing up across the Northern Hemisphere. Pressure patterns in the Arctic play a huge role in the weather we have across the United States. One of the ways we measure this is by the Arctic Oscillation. It has two phases… positive and negative. The chart below shows the positive phase on the left and the negative phase on the right…<\/p>\n

\"arctic_oscillation\"<\/a><\/p>\n

As you can see… a negative phase of the AO is usually a good indication of cold temps across the eastern half of the country. The stronger the phase… the more influence the signal can have. The AO has been in a negative phase for a while now and that matches up with the cold weather we’ve been experiencing. The latest forecast calls for the AO to go severely negative in the coming days…<\/p>\n

\"Blocking\"<\/a><\/p>\n

That is about as negative as you can get. If this were the heart of winter… sub zero arctic air would likely be on our agenda. That said… it’s going to be plenty cold enough for this time of year and the models tell the tale…\"GFS\"<\/a> \"CFS\"<\/a>That shows the colder than normal temps hanging tough into early April. I do expect a milder signal to show up for the second half of April into May and that is likely to come with a hyper active thunderstorm season.<\/p>\n

The shorter term weather will feature the chance for some light rain or light snow later Wednesday and a more potent storm this weekend into early next week. I will touch on those later today.<\/p>\n

Have a great Tuesday and take care.<\/p>\n","protected":false},"excerpt":{"rendered":"
