SIOUX FALLS, S.D. (Dakota News Now) -- While we did get some rain overnight into our Sunday morning, it ended up being less than what was expected. Most areas picked up between a trace and 0.10″. Winds have increased behind the system that brought the rain and will also bring in some cooler air to begin the week. Don’t expect that to last long though.

TONIGHT: Clouds will begin to decrease with skies becoming mostly clear to partly cloudy overnight as higher pressure moves in. Winds will be strong out of the N and NW at 15-30 mph with gusts up to 45 mph, but will decrease to roughly 5-20 mph overnight. Lows drop back into the mid 40s to low to mid 50s.

MONDAY: We’ll start the day with plenty of sunshine but some clouds will trickle in for the late morning and afternoon hours. Winds will remain breezy out of the N and NNW at 10-20 mph with gusts upwards of 30 mph. Highs top out only in the upper 60s to mid 70s, which will run about 8-15 degrees below average. Monday night will feature a mostly clear to partly cloudy sky with winds calming to 5-10 mph and shifting to the S and SE late and lows in the 40s and 50s.

TUESDAY: A warm front will push across the southern parts of the area into the afternoon, which will keep skies partly cloudy. North of there, expect a sunny to mostly sunny sky. Winds will be out of the S at 5-15 mph, which will bring in the warmer temperatures. Highs will climb back into the mid 80s to near 90. Lows fall back into the 50s and 60s.

WEDNESDAY: This will likely be the hottest day of the next 10 as another warm front pushes through, bringing it another surge of warm air. We’ll see a mostly sunny to partly cloudy sky with a S to SSE wind at 5-15 mph. Highs surge well into the 90s with some triple digits along and west of the James River Valley. Clouds will start to move in Wednesday night ahead of the next system. Lows only fall back into the 60s and 70s, making it for a warm and muggy night.

THURSDAY: The next system will approach and bring the chance for showers and thunderstorms to the area. While it is too early to say at this point, a few strong to severe thunderstorms can’t be ruled out with the heat and humidity in place. Highs will remain in the upper 80s to mid 90s with lows in the 60s.

FRIDAY AND BEYOND: A few showers and isolated thunderstorms may linger for the southern half of the area Friday, but the rest of the weekend is looking fantastic with clear conditions, warm temperatures and low humidity levels. Next week is looking to trend warmer and dry once again and the latest 8-14 day outlooks are suggesting that theory. Highs will be in the low to mid 80s Friday, with mid 80s to low 90s Saturday and Sunday. Highs next week look to be mostly in the upper 80s and 90s.
