It’s another warm summer day, with temperatures in the upper 70s to low 80s. And you might have noticed that the humidity is starting to creep up. That trend will continue over the next few days.
Late tonight, the winds at cloud level will bring in a little moisture, so we’ll carry a chance of thunderstorms overnight. It doesn’t look like they’ll be strong, with the exception of western South Dakota, where there is a risk of large hail and strong wind – and a flash flood watch is posted through tomorrow night.
Southeast winds pick up tomorrow, which means the flow of humidity will become stronger. We could see thunderstorms developing during the day, strongest in the western half of South Dakota.
On Friday, energy streams into the area. There will be a higher amount of water available in the clouds, so we’ll have a risk of heavy rain in eastern South Dakota. We could also see severe storms East River in the Friday-Saturday time period.
We’ll have to keep a chance of thunderstorms in the forecast for Sunday, but we expect they will lack the energy of the storms we’ll see Friday and Saturday.
The forecast should quiet down as we head into next week and say goodbye to what has been an extremely wet June.
