After a rainy start to the weekend for some, the afternoon saw just a few areas of patchy but decreasing clouds and afternoon temperatures in the 70s to low 80s. Near 90 degrees temps were found along the western edge of SD.
Tonight’s forecast includes some isolated thunderstorms for those in and near the Black Hills. Some of those storms could become severe with large hail or strong winds but once the sun goes down, clear skies will be found across KELOLAND with overnight lows in the 60s.
There is some model data pointing to isolated morning showers in the southeast but even if those showers verify, sunny skies will return for all of KELOLAND tomorrow afternoon with warmer afternoon temps in the 80s to near 90 in the east while mid-90s will be found in central and west KELOLAND. Central and east KELOLAND will have breezy southeast winds at around 15 to 30 mph; gusts will be up to 40 mph.
A center of low pressure will pass through KELOLAND tomorrow night and Monday. This means parts of KELOLAND; especially northern South Dakota will be in for a stormy start to the work week which is welcome news because drought conditions have been getting bad in the north.
The SPC has placed a bullseye of severe weather over central ND and north-central SD. Beginning storms will have large hail and strong winds but as the storm cells mature and merge, strong winds will be the main threats. Severe storm potential goes down after Midnight.
Monday’s highs will be in the 70s for most of the area however, the southeast will still top out in the 80s.
Mid-week (Tuesday – Thursday) looks quiet and sunny overall. Highs will be near the climate average, in the upper 70s to lower 80s.
We’ll bring back thunderstorm chances at the end of the week as the next upper level low is expected to arrive.
