A large low pressure circulation located in Canada will rotate areas of vorticity through our region over the Memorial Day Weekend.  The overall cyclonic flow and cold pool of air aloft will result in considerable instability cloudiness mixed with sunshine throughout the weekend.   (Friday’s sky cover will be a good example.)

Exact timing of these disturbances can be difficult to pin down for Sunday and Monday.

Saturday will start with sunshine,  but instability cloudiness will develop.  A small area of vorticity moves through late Saturday afternoon, with thicker clouds and some light showers.  High 73

Sunday currently looks to be the better day, with more sunshine and no precipitation.  High 74

After morning sunshine, another weak disturbance moves through Monday afternoon, with increased cloudiness and the possibility of light scattered showers.  High 76
