Here is my weekly weather quiz question for the last time. What is a “Land Breeze? Here is the correct answer. A Land Breeze is a coastal breeze at night blowing from land to sea, caused by the difference in the rates of cooling of their respective surfaces.

An Upper Level Low Pressure Trough (“U” shape) is sending frontal systems our way and still even more moisture. We had weak high pressure that brought plenty of sunshine for us Saturday. The graphics for days 1-3 Show a complex frontal system, warm front first followed by a cold front that moves in today. The graphics for days 3-7 Wednesday through next Sunday show the continuing series of frontal systems that will slide into the Pacific Northwest through the period.
