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) is sliding down the large upper level trough of low pressure (“U” shaped yellow line) is moving closer  Oregon which will means more onshore flow that will drop a cold front down from the northwest. We will see more clouds and cooler temperatures again with at least a chance of sprinkles. It will be warming a bit by the 4th of July Holiday. This also means pretty good weather for the “Butte to Butte” and the”Pre  Classic.” It looks like the only chance of getting wet on the 4th of July will be at the lake or pool or possibly in the mountains.

Advisories:  NONE AT THIS TIME.
