Some spotty thundershowers have popped up in central and northeastern South Dakota. They are moisture-starved, so not much rain is expected with them. But there is some lightning with them, so take care if you hear some thunder during your outdoor activities.
At their current movement to the southeast, there may be a thundershower in the Sioux Falls area late this evening, about the time the fireworks displays are ongoing. You might want to take an umbrella.
Overnight the clouds will clear, but the south winds will remain. That will bring warm and increasingly humid air into the region. Saturday will be a mostly sunny day, with a highs in the upper 80s to low 90s in East River… and the mid 90s West.
Sunday will be another warm and somewhat humid day in Sioux Falls and SE KELOLAND, where temps might top 90 degrees. The rest of the region will see winds switching to the northwest and then the north, so it won’t be quite as warm.
Model differences exist for next week. One wants to park a high pressure ridge over us, which would give us a sunny and hot week. Another gives us cooler temps and chances for rain. Both models, though, warm us back up Friday through the following weekend (July 16-17).
