Here is my weekly weather quiz questions. This is a “different” kind of question. Which President of the United States holds the record for the coldest and the warmest inauguration day? If you know when (the dates) you’ll get an extra round of applause. Please post your answer as a comment after these forecasts. The first person to post the correct answer will win one free week of free personalized weather forecasts tailored to your needs. Good luck.

An upper level low (See the concentric circles in the Gulf of Alaska) will be bringing in a few more clouds and cooler temperatures again most of this week, warming a bit by the 4th of July Holiday. This also means good weather for the “Butte to Butte” and the”Pre  Classic.” The large upper level trough of low pressure (“U” shaped yellow line) is moving closer to the Oregon coast which will mean more onshore flow that will increase the clouds even more than I expected and decrease the temperatures as it continues to send weak disturbances our way.

Advisories:  NONE AT THIS TIME.
