Multiple locations in St. Croix County reported more than 6" of rain through this morning where serious flash flooding has occurred. As of noon today, Emerald had reported 9.13" of rain. In Baldwin, 8.22" of rain fell by 7:30 this morning, with additional rainfall since then. A Flood Warning remains in effect for parts of Pierce and St. Croix County through 10 a.m. Tuesday.
Thankfully we are getting a bit of a break across the Chippewa Valley this evening although the atmosphere is still packed with moisture and there are a couple clusters of storms and heavy downpours across the upper Midwest. Much like the storms we saw overnight and this morning, the storms that still exist this evening are slow movers with heavy rain, bringing flash flood threats to southern Wisconsin and parts of Minnesota and northern Wisconsin.
Within the Chippewa Valley, we are largely dry this evening. While there is a chance we could see more showers and storms develop within the area this evening, chances are generally low. These types of storms are challenging to forecast, however. If any additional rainfall does develop, we will once again have to monitor the flash flood threat due to the excessive amounts of rain we have already seen.
As always, never drive through flood water. If you encounter flooded roads at any point within the next several days, do not try to drive through it. It only takes 18" of water to float most cars, and large trucks can be swept away in just two feet of water. Roadways may also be washed out under flood waters.
By Tuesday, there will be just a slight chance for showers and storms. Chances pick back up for Wednesday as a cold front moves through. That cold front won't do much to bring us cooler weather though. The heat and humidity are here to stay for the rest of this week.
Despite plenty of cloud cover, temperatures have rose into the 80s in parts of the Chippewa Valley this afternoon with dew points are pushing 70. By tomorrow, highs will be near 90 with just as much humidity. You'll definitely want to have the AC running and limit time outdoors over the next several days, as heat indices will likely soar into the 90s.
While storm chances are much lower in the second half of the week, we'll still have to contend with a possible holiday weekend heatwave with temperatures in the low 90s expected for several days in a row.
