A high pressure ridge (“Arch” shape in blue arrows offshore) is slowly covering us bringing plenty of sunshine and warmer temperatures back. An upper level low will slide in toward the weekend returning the slight chance of showers. The temperatures will fluctuate a bit lower, a bit higher, then back up a bit, but will stay pretty stable through the weekend.
