Winds pick up once the snow ends


As the snow slowly comes to an end this evening a strong northwest/west wind will grip the Stateline.  The low pressure system that brought us the snow Monday will lift northeast into the New England states and remain parked there for the next several days.  At the same time cold Canadian high pressure will slide down the Plains pulling down with it some very unseasonably cold air.  Both the high and low pressure systems will be strong and the difference in pressure between the two will help create the strong wind we'll feel later tonight and tomorrow.  The image of the left shows lines of equal sea level pressure.  The closer the lines are to each other the strong the wind.  The further apart the lines are the lighter the wind.  Wind gusts tonight will near 30 mph and top 40 mph Tuesday afternoon.  Strong winds will continue Wednesday before the low in the east moves into the North Atlantic.  Temperatures tonight will drop into the teens behind a very strong cold front and only rise into the upper 20s to near 30° by Tuesday afternoon.  Wind chills will stay in the single digits Tuesday and drop below zero by Tuesday night!
