Well, I'm glad I got a ride in at Theo Thursday night before the monsoon rains hit. The Twin Cities got slammed by a solid 1.5" of rain and high winds in the wee morning hours on Friday. Sure woke me up!
The lightning show was crazy!...nothing like I've seen before. Eden Prairie clocked a wind gust of 55 mph and with a wind like that I suspect there will be a lot of downed branches/trees on the trails. Not exactly an ideal way to kick start the biking weekend.
A persistent stormy pattern stays in place this weekend. Groups of thunderstorms will occasionally move through the area potentially producing damaging winds and flash flooding.
Summe-time thunderstorms like this are often difficult to predict. Storms one day often dictate where and when storms will form the next day. The National Weather Service in La Crosse best summed up what we can expect this weekend:
Saturday: Broken sunshine, humid. H: 89 Wind: SSW 10
Saturday Night: Thunderstorms w/heavy rain (0.50"+). L: 72 Wind: S 10 G 30
Sunday: Afternoon thunderstorms. H: 89 L: 70 Wind: SW 10-15
Monday: Late-day thunder. H: 90 L: 71 Wind: NW 2-4
Tuesday: Mostly cloudy, showers and storms. H: 90 L: 71 Wind: SE 10
Wednesday: Late afternoon storms. H: 89 L: 68 Wind: S 2-4
With the high humidity and several rounds of rain, expect limited drying of the trails. I predict many will be closed throughout the weekend.
Lutsen 99er CycleCast
The Lutsen 99er is less than a week away. Whether you're racing or spectating check out 2WW's CycleCast for next weekend. The race course just got hammered by rain as well...with more likely to fall through next week.
The long range outlook is looking a little drier (yes!) but models still have time to change their minds. Will be a great time, regardless. I'll be racing, so see you "up north"!
Summer brings warm afternoons perfect for biking, but the summer heat and humidity can also spark thunderstorms and severe weather. Be prepared for any type of adverse weather headed your way with Aeris Pulse.
