We experience weather, that eventually defines the climate. Recently updated annual climate information across the USA has put into use the so-called new normals. By agreement among the climatological community, the normals are based on three decades worth of daily statistics recorded at approved weather observing sites. Proably the biggest change, previously noted in blogs, is the increase in overnight minimum temperatures in the winter season in our neck of the woods.
From the data I have briefly examined, made available by NOAA, the overnight low temperatures in the Twin Cities during the coldest time of the winter season (mid January), went up from tree degrees to seven degrees. In large part, this change was a result of dropping off the rather cold decade of the 1970s and incorporating the past ten years of documented warming.
I came across a story on the web, attributed to Livescience.com, that stated that there were record temperatures set in every state during the month of July. Comments to the story remarked on the coolness in Washington State throughout the summer. However, I did find a report on the Seattle NWS webpage, that indeed, Seattle set a record high of 79 on July 6th. This broke the previous record of 77 set in 2007. Can you believe everything you read on the internet?
There has been some frisky solar flare activity on the sun recently. I pulled this file photo out of my archive of the solar activity forecast posted way back in March of 2009. It appears heavily weighted to a historically document cycle. Or as I like to say, we are due.
You have realized by now that the weather in our neck of the woods is rather tranquil, but on the cool side. Overnight lows dipped into the 30s in the favored cool spots in northeast Minnesota. About the Twin Cities, the burbs dipped into the 50s.
I like this graphical post from the Chanhassen NWS website this morning that summarizes the weather in the upcoming days.
If timing on precipitation is right, we may catch a break in Minnesota and find the showers moving through on Thursday night through Friday night, leaving behind dry weather for the weekend.

By meteorologist Bill Endersen:
This afternoon's cumulus clouds had a friendly, fluffy look as they decorated the sky. Farther north some clouds did develop into widely scattered showers in the Brainerd Lakes area, but they dissipated quickly.
The cool air mass gave us a 58-degree morning in the Twin Cities while it was jacket weather to the north. Hibbing cooled to 38 degrees while Embarrass was the chilliest spot with 36 degrees.
Tomorrow morning will be in the 40s up north and 50s in central and southern Minnesota. For you early risers, look for the bright planet Jupiter high in the southern sky toward dawn.
The Twin Cities should drop to about 58 and then give way to an afternoon high near 80 again.
We certainly could get more hot weather before summer ends. The record high for today in the Twin Cities is 101, so really toasty weather can still come our way. So far we have not had any 90s this August.
Showers and thunderstorms remain likely for Friday and Friday night, before moving off and leaving Minnesota with a very pleasant weekend.
Dallas watch continues as they are experiencing their 40th consecutive 100-degree day. The string will continue to grow and there is no rain in their forecast for the next week, so the Exceptional Drought will get even worse.
Enjoy a lovely evening.
