Excessive Heat Continues
I think it's safe to say that this stretch of hot, hazy and humid weather will be our LONGEST stretch of hot weather this summer. Including both days this weekend, we'll be spending nearly 7 to 10 days with temps in the 90s and dew points in the tropical category. A/C's are running overtime now, neighbors are complaining and the mosquitoes are relentless - YES - this is summer in Minnesota! I don't know about you, but I'd rather be sweating than shivering in -40F wind chills! Regardless of what kind of weather you like, this heat CAN and IS serious, make sure you take the proper precautions: Limit your time outdoors, drink plenty of fluids and check in on sensitive groups. This is quite a heat wave, in fact I count 18 states under EXCESS HEAT HEADLINES, where temperatures are at dangerous levels and can be life threatening in not taken seriously.
Why Is It So Hot?
The strong upper level winds have lifted north into Canada, allowing a massive bubble of heat and humidity to lift north along with it.

Johnny Cash Comes to Mind - Burning Ring of Fire
Do you remember that old song: Ring of Fire? Typically in a weather setup like this, showers and thunderstorms will fire up on the outer ring of the extreme heat, right near where the strong upper level winds are situated. Take a look at the map below, notice how there are scattered clusters of showers and storms rotating around the dome of extreme heat and humidity in a ring-like fashion. These storms show up as an orangeish or reddish color, like fire, thus the name "Ring of Fire".
This "Ring of Fire" has set up nearly on top of us and that is why we've had so much rain as of late. The radar rain estimates over the last 7 days are quite impressive - note the widespread 5" to 6" and perhaps even 7" amount showing up around the Twin Cities:

Not Quite Done With the Thunder or Rain Chances
As long as we're close to the "Ring" mentioned above, we're not quite out of the woods when is comes to rain and thunder chances. In fact today, parts of MN are under a SLIGHT RISK of severe weather:
Severe Risk For Sunday
Heavy Rain Chances Continue
If storms fire late Sunday into Monday, there is a chance that they could produce some additional heavy rainfall. The image below suggest that there could be up to an additional (nearly 2") from PM Sunday in to PM Monday

Looking for something to do today? Come check out the Springbrook Nature Center as they take a look back on the July 18th, 1986 tornado, 25 years later.
