We’ve already seen a big drop in the temperatures in NW South Dakota behind the cold front. Now we’re watching showers developing right along the northern border that will progress southeast through the overnight.
The best chance for rains is east of the James River. Moisture has increased a little bit, so some spots like Watertown or Canby could see up to half an inch of rain. Most others like Sioux Falls or Aberdeen could pick up about a quarter of an inch. Either way, this is not a drought busting system. Unfortunately it is about our only chance for the coming week.
A few storms are possible during the overnight but are most likely east of Jackson, Minnesota. Any storms will be wind producers and not much else. Most rains will be moving east of KELOLAND before the morning commute to work.
West River, about all we’ll see is a chance for drizzle. There will also be very windy periods, with gusts already nearing 40 mph. That leads to a heightened fire danger.
The air aloft will be much cooler later tomorrow. That could spawn a few very spotty showers later in the day, moving from Aberdeen towards Brookings and Sioux Falls. That colder air could also mean some patchy frost by Tuesday morning for far northern South Dakota!
The rest of the week looks very dry with high temperatures only around the lower 70s.
