Temperatures on the Rise
Isolated Storm Chances Tonight
SIOUX FALLS, S.D. (Dakota News Now) - We’ve had a nice break from the heat and humidity, but that’s about to return this week.
A weak upper-level feature will move through late in the afternoon into the evening and despite a low amount of moisture in place, there may be enough energy and moisture available to squeeze out a few isolated showers and thunderstorms. The best chance for this will be between 6 pm and sunrise Tuesday and not everyone will see rain. This will mainly be central and eastern South Dakota. This will be very isolated.
Tuesday will feature a mainly sunny sky with highs in the mid 80s to low 90s.
Wednesday will be the hottest day of the week with highs in the 90s and lower 100s with dewpoints in the 50s to low 60s. We’ll need to watch for the potential of any heat alerts being issued for Wednesday. A cold front will spark a chance for widely scattered showers and thunderstorms very late in the day Wednesday heading into Wednesday night, and the Storm Prediction Center has a level one marginal risk for isolated strong to severe thunderstorms roughly north of a line from Brookings to Chamberlain to Pine Ridge.
After Wednesday, rain chances remain sparse throughout the rest of the extended forecast but there are isolated to widely scattered chances for showers and thunderstorms over the 4th of July holiday. Despite that, chances are low and it looks to remain mostly dry through most of the holiday weekend. Highs cool back into the upper 70s to mid 80s to begin the holiday weekend but will climb back into the 80s and 90s for the second half of the holiday weekend and the 4th itself.
