Heat to Continue for Foreseeable Future
Temperatures to Run 10-20 degrees above average
SIOUX FALLS, S.D. (Dakota News Now) -- TODAY: A cold front will sweep through from west to east. The front will mostly be in dry fashion, but the main thing it will do is shift the winds back to the N and NW and bring in some slightly “cooler” air. Into Sunday night, there could be a few showers and thunderstorms that pop up along and east of the James River, but not all models agree on this and the conditions for thunderstorm development is not the best. With that being said, there still is the possibility some could develop and the best time for that will be between 5 PM and 3 AM. Winds will be breezy throughout the day and could gust as high as 30-40 mph. Highs range from the mid to upper 80s west to the mid 90s east, so a little better than the triple digits but still hot. Lows Sunday night range from the 50s to low 60s north and west to around 70 southeast.
MONDAY: Most of the day will be dry with mostly sunny to partly cloudy skies. Into the afternoon and evening hours, some showers and thunderstorms could develop in northern and western South Dakota along a stationary boundary. The SPC does have a marginal, level one risk for severe thunderstorms in these areas with hail and high winds the main threats. The southeastern areas should stay dry. Winds will remain breezy out of the S and SE at 10-20 mph. Highs rise back into the mid 90s to near 100.
TUESDAY AND WEDNESDAY: A boundary will sit just to our north, which will bring some extra clouds from time to time and sporadic chances for pop-up afternoon and evening showers and thunderstorms. The better chances look to be across the northern and western parts of South Dakota. Highs will remain in the mid 90s with overnight lows in the 60s to low 70s. Dewpoints will be up into the low to mid 60s, so it’ll be feeling muggy.
THURSDAY: A cold front will approach Thursday afternoon into Thursday night and bring a chance of showers and thunderstorms to the area. The better chance looks to be Thursday night. While it is too early to determine, there could be the possibility of some stronger storms with the heat and humidity in place as dewpoints look to be in the mid 60s, possibly even upper 60s. Temperatures will top out in the low to mid 90s with lows in the 60s.
NEXT WEEKEND AND BEYOND: A few showers and thunderstorms may linger along and east of the James River Friday, but after that, the forecast looks great with lower humidity levels and plenty of sunshine. Highs will only be in the 80s Friday, but will climb back into the 90s for the weekend and continuing into the beginning of the following week. The latest 8-14 day outlooks from the CPC, which runs from June 13-19, continues to show a good chance of a warm and dry weather pattern.
