Happy meteorological summer!
June 1st marks the start of meteorological summer in the northern hemisphere. The months of June, July & August are the three warmest months of the year in Minnesota, meteorologically speaking. Astronomical summer begins June 21st at 6:28 am CDT.
A cool front is crossing Minnesota today. As the front slides through, the atmosphere is unstable enough to trigger a few scattered thunderstorms. A few of these may reach severe limits. (wind gusts of 59 mph and/or hail 1" in diameter or greater)
With any strong to severe storms that do manage to form, the primary threat will be high winds and hail today. Still, you can never totally rule out an isolated tornado, or gustnado with severe rotating thunderstorms.
There could be scattered storms at any time today but the best chance for severe storms appears to be in a window between 2pm and 9pm. Keep an eye to the sky and have your weather radio handy today.
Warm & dry spring 2010:
With temperatures running 1.4 degrees above average in the metro, May closes one of the warmest and driest springs on record in Minnesota.
Here are some numbers for the Twin Cities:
March: +8.9 degrees
April: +8.3 degrees
May: +1.4 degrees
Spring 2010: +6.2 degrees!
The Twin Cities recorded 5.51" of rainfall this meteorological spring. That's 1.9" below average.
June: Warm and (usually) wet
June is typically our wettest and 3rd warmest month of the year in Minnesota.
Temperatures and humidity usually climb noticeably in June as summer kicks into high gear by mid month. In the Twin Cities the average high climbs from 75 today, to 82 by month's end. Average lows warm from 54 to 61.
With ample thunderstorms and tropical downpours at times, average rainfall in June is 4.34".
We may get our first shot of June rain today. Most areas, including the Huttner Weather Lab lawn and newly planted vegetable garden can use the rainfall!

Call it Minnesota's version of the midnight sun.
The next 6 weeks feature the longest daylight of the year in Minnesota. The summer solstice is roughly 3 weeks away, on June 21st. That means the sun is close to its highest point in the sky, and the farthest north on its annual trek into the northern hemisphere sky.
At precisely 6:28 am CDT on June 21st, the sun will be directly overhead at 23.5 degrees north latitude. In Minnesota, the Twin Cities lies at about 45 degrees north. That means the sun will be at 68.5 degrees above the horizon on June 21st at solar noon. That's the highest point in the sky during the year.
Another interesting aspect of the sun this time of year in Minnesota is that the sun rises and sets north of due east and west. This is why the sunlight falls on the NORTH side of your home in June in the morning and evening. It's uplifting to see windows and other areas that do not get direct sun most of the year basking in sunlight.
The higher sun angles are accompanied by the longest daylight. The week of June 21st features about 15 hours and 36 minutes of daylight, and less than 9 hours of darkness. The sun sets in the central Twin Cities as late as 9:03 pm from June 20th until July 3rd.

Even more remarkable, the sunset in Hallock in northwest corner of Minnesota is as late as 9:35pm in late June! That means civil twilight provides considerable light in the sky until 10:17pm.

Full Moon: 5:31am
Here is a great site for tracking sun and moon rise and set times for any location. It's a great planning tool for summer vacation trips.
Enjoy the long lazy daylight the next 6 weeks!
