A Funnel within a Funnel: Severe weather tends to decrease late in summer across the country. The atmosphere aloft begins to warm as the jet stream continues to drift north into Canada.

Came across the vintage photo from the NOAA's National Weather Service (NWS) Photo Library of a rope tornado encased within it's own funnel in Jasper, MN.

An incredible 8 consecutive day stretch of dry weather fell upon the Twin Cities...perfect for kicking up the dust on the trail. While rain on Friday settles some of this dust, the extended outlook remains dry. This is payback for the waterlogged June we had.

Massive Mayfly Emergence: Ever capture a mayfly in your face while riding? Chances are you did if you've been biking in southeastern MN. During summer mayflies are known to emerge along a stretch of the Upper Mississippi River Valley from Davenport, Iowa through St. Paul. The results of which are often captured by doppler radar. Swarms...even piles of mayflies were reported July 20th near La Crosse.
Hazy sky, Brilliant Sunset: Wildfire season has begun in Canada and an expansive area of fires continue to burn in the Northwest Territories. Persistent northwesterly flow could help drag this wildfire smoke down into the Twin Cities.
Summer Derecho: "Derecho" is a Spanish word meaning "direct" or "straight ahead." A funny word, yes, but the results can be dangerous. A derecho event blew across northern Minnesota Monday night. Luckily, for our trails sake, the most damaging winds missed the Twin Cities (summer-time thunderstorms are notoriously difficult to predict).
Below is a recap by the Storm Prediction Center of the derecho event last Monday night.
In true Minnesota weather fashion, we get a case of weather whiplash. Temps go from 60s to 90s (a 25 degree jump) in just a week's time. This dry stretch of weather has favored local riding as well as those coming into town for the Southside Sprint this Sunday.
This warming trend continues into early next week with a possible 90+ degrees in the forecast by Monday. Chance of rain looks rather hit or miss for now.
Saturday: Afternoon thunderstorms. H: 84 Wind: S 10
Saturday Night: Cloudy. L: 68
Sunday: Evening isolated thunderstorm. H: 88 L: 74 Wind: S 10
Monday: Hot and humid. Thunder late. H: 91 L: 72 Wind: S 10-15
Tuesday: Partly cloudy, a passing shower. H: 90 L: 69 Wind: SW 10-15
Wednesday: Sunny, slightly cooler. H: 83 L: 66 Wind: N 10
Fire in the Sky: Wildfires have been raging across the western U.S. all week. When the winds aloft allow, the Midwest can experience a hazy sky from the western wildfires. The result? Spectacular red and orange sunsets.
The fine particles of smoke suspended in the atmosphere refract and bend the light (even more so when the sun angle is low in the sky). Upper-level wind pattern becomes more zonal (west to east) over the next several days. This will serve as a constant conveyor belt of smoke from the Pacific Northwest into the Midwest. Get the cameras ready...the sunsets are sure to be spectacular.
Severe Weather Slows: Towards the end of summer (July & August), the threat for severe weather tends to decrease. By this time, the jet stream has retreated north of the international boarder and the air aloft begins to warm considerably.
Warmest of the year: Minneapolis/St.Paul hit 90 degrees so far only once this summer. With Monday's forecast of 91 degrees, we just might experience the warmest weather of the year to date.
Summer heat soon fades, however. Cooler weather returns by next weekend.
Rain on Fridays is never a good sign for weekend riding plans. Nearly 1 inch of rain fell across the metro leaving many trails too wet to ride.
Indoor trainers might be a good idea as more rain is expected the rest of the weekend.
Overall rainfall this July has been rather scarce in comparison to last month. The rain on Friday, however, was record-breaking in some areas.
Canadian high pressure flexes its muscles next week with dry but exceptionally cool weather. High temps Monday may stay in the 60s. Hello Autumn!
