Here is my weekly weather quiz question for the last time. What is “Limnology? Here is the correct answer. Limnology: In hydrologic terms, the branch of hydrology that pertains to the study of lakes.

The persistent blocking Upper Level High Pressure Ridge (“Arch” shape) will be slowly letting go its hold on the Pacific Northwest with Upper Level Low Pressure taking over early next week. The problem is that it will not be bringing rain with it, just cooler more normal temperatures for the season. The graphics for days 1-3 show a weak front will fall apart as it tries to move over the Pacific Northwest. The graphics for days 3-7 Wednesday through next Sunday show what little frontal activity will occur through the period until a cold front move in between Friday and next Saturday.
