Skies are mostly sunny across KELOLAND, with some popcorn-type cumulus clouds starting to form in the sunshine. Temperatures are about 10 degrees above-normal, in the upper 70s to mid 80s, with only a light breeze.
Tonight skies will be clear - although it is possible a few spotty showers or spotty light thundershowers may pop up during the overnight hours in central and NE South Dakota. Lows will be in the upper 50s, with a light south breeze helping to keep us mild.
Tomorrow will start with sunshine for most of the area, and it will be very warm. Highs will be in the low to mid 80s again. We could see some rain in Aberdeen as a low pressure forms in NE South Dakota. During the afternoon hours, we’ll see thunderstorms erupt in western and central South Dakota.
The Storm Prediction Center rates southwest South Dakota as having a slight risk of severe weather tomorrow afternoon and evening, with mainly a hail and wind threat. There is at least a marginal risk for areas west of I-29. A half-inch to an inch of rain is possible in those areas.
Rain will continue on Friday, with more embedded thunderstorms. Rain will become the issue. Friday’s highs will be in the 70s, with a south wind pumping more moisture into the storms.
Saturday is looking cloudy and breezy and rainy, especially in the southern half of KELOLAND. Temperatures will fall as a result of brisk winds. Saturday’s highs will only be in the upper 50s to low 60s. Rain should end late Saturday night, with much of KELOLAND having a three day rainfall total of one to two inches.
A broad area of low pressure will dominate the central US – including KELOLAND – on Friday. That will bring widespread clouds, showers and thunderstorms both Thursday and Friday. Highs will be in the 70s to low 80s. At this time it appears we could see some two-day totals of an inch or more of rain.
On Sunday, there is a slight chance we could have some early morning showers, but skies should clear Sunday afternoon. Highs will be only slightly cooler than normal, in the mid to upper 60s.
It looks like we will warm right back up on Monday, with sunny 70s. Next week looks like it will be warm all week right into the final weekend of May (the Memorial Day holiday) with widespread 70s and a few 80s during that time period.
