move NE of the region Fri night into Sat night while pulling a
series of low pressure troughs over the N portion. High pressure
will build over the far S portion Fri into Fri night, then shift
S and SE of the area Sat night into Sun. Another low will track E
across the N portion Sat night and Sun while pulling a cold front
over the area. The front will stall across the central waters
Sun, then slowly drift N and NE as a warm front Mon and Mon night
as high pressure shifts N towards the S waters.
