The last thing people want as we head in to our first full weeks of astronomical spring is to have to worry about freezing cold weather. Unfortunately the cold at this stage of the season is not uncommon, and this weekend is setting the stage for a significant shockwave of springtime cold air.
Upper Level: ridging builds in for Wednesday. This slowly erodes away as a deep trough approaches this weekend.
Surface: High pressure in place for Wednesday slips offshore to our east by Thursday. Low pressure tracks to our north and west Thursday night and Friday. Some showers likely Thursday night and Friday out ahead of a trailing cold front expected to come through the region late Friday. Deeply anomalous cold arrives Late Saturday as an arctic cold front approaches. In the wake of the front, winds are expected to really ramp up Saturday night and Sunday with gusts to 60 mph not out of the question.

Thursday night/Friday: cloudy, showers – late day cold front passage.
