A trough of low pressure (See “U” shape offshore) is moving Eastward away from us. A weak cold front will be moving through Saturday. Weak high pressure will try to take over for a little warming Sunday and Monday, but another low will follow close behind it so don’t look for any dramatic changes in our weather patterns.
