It was Eau Claire’s hottest day in over three weeks. High temperatures topped out above 80 degrees for the first time since August 20th when we were 81. It’s been 24 days since we’ve been warmer than 81 and you have to go back 34 days to August 7 since we’ve been warmer than 82 (our high that day was 85).
With the warmth and sunshine, we also had oppressive dew points in the 60s to near 70 today, also a first in a couple weeks. While temperatures will go down for the rest of the week, it’ll still be muggy with the potential for both a lot of rain and some severe storms.
Impacts: Scattered strong to severe thunderstorms will be possible with each of several rounds of heavy rain that will move through over the next two days.
Timing: The first round moves through Wednesday morning, with scattered activity possible through the evening before another round moves through overnight and a third round arrives during the day Thursday.
Details: Again, each round could contain severe storms with strong straight line wind gusts, large hail, and even isolated tornadoes. However, the biggest threat remains heavy rainfall and flash flooding. Several inches of rain that could exceed 4″ in scattered spots could add up between all rounds over the next two days. Widespread rain totals of over 1-2” is likely.
Temperatures cool off Friday with only a few light showers, but we’ll warm up again late weekend and early next week. That comes with more rain chances.
