Friday April 13 2018

There are some people who have a fear of this day, but it may be good luck for you. We already start with 60s in many places and the race is on for 80ºF. As I have been saying all week, we often end up warmer than models first suggest and there is a little split as to how warm we will get.  See the contrast of forecast for today’s high temps below.  But with a warm up and expected crash of temperatures next week, there is the risk of sever storms across the nation. There will be a widespread outbreak of tornadoes and hail producing storms along a very strong cold front beginning today… But not here.  Just some morning sprinkles.  Our chance for storms will increase Sunday night and Monday morning, then cold enough for snow to return to western Maryland Monday.
