My weekly weather quiz question will start tomorrow instead of today due to the holiday.
________________
A trough of low pressure (See “U” shape offshore) is moving Eastward away from us, but another will follow close behind it so don’t look for any dramatic changes in our weather patterns. A cold front will be moving through Friday, then a little warming next weekend.

Advisories: NONE AT THIS TIME.
