SIOUX FALLS, S.D. (Dakota News Now) -- Thanks to a cold front, it did bring some minor relief from the heat but it was still rather warm out there. The front also kicked up the winds a little bit as well as wind gusts on our Sunday have been in the 30-40 mph range with some isolated gusts over 40 mph. If you are looking for some more relief from the heat, unfortunately it won’t be for a while still... oh and humidity levels will be slightly higher this week as well than in past days.

TONIGHT: A cold front will continue to drift east and then basically stall out and move northeast. Skies will be clear to partly cloudy. Winds will be out of the S at 5-15 mph, but areas north and west will see more of a N to NE wind. Lows range from 55-60 north and west to around 70 southeast.

MONDAY: It’ll be another hot and muggy day as a stationary boundary and area of low pressure moves in from the southwest. While most of the day will be dry, there will be showers and thunderstorms that develop along that boundary after 3 PM, continuing into Monday night. A marginal, level one risk of strong to severe storms is in place northwest of a Watertown to Chamberlain line with a slight, level two risk northwest of Aberdeen and Pierre. Hail and damaging winds would be the main threats in these areas. The southeastern hometowns will stay dry Monday and Monday night. Winds will be out of the S and SSE at 10-20 mph. Highs top out in the mid to upper 90s with lows in the 60s to low 70s. Dewpoints will be in the upper 50s to mid 60s.

TUESDAY AND WEDNESDAY: We’ll see a partly to mostly sunny sky with sporadic chances of afternoon and evening showers and thunderstorms. Severe weather is not expected during this time, but the chances are not completely zero. Winds will remain out of the S and SSE at 5-15 mph with gusts up to 25 mph. Highs will remain in the mid to upper 90s with lows in the 60s to low 70s.

THURSDAY: Thursday could be an interesting day, especially heading into the evening and overnight hours. While the daytime looks mostly dry with a stray shower or thunderstorm possible in the afternoon, an area of low pressure with an associated cold front will move in Thursday night and that will bring a better coverage of showers and thunderstorms. There is the potential of seeing strong to severe thunderstorms, and the SPC has put out a risk of severe thunderstorms for the western half of South Dakota. We’ll watch this in the coming days, but the potential is there with the heat and humidity in place. Highs will be in the 90s to near 100 with dewpoints in the mid 60s.

NEXT WEEKEND: The chance for showers and thunderstorms continues Friday along and east of the Missouri River as the cold front moves east. Once that moves out, high pressure will settle in and give way to a beautiful weekend with much lower humidity levels. Highs will cool to the 80s Friday, but return back to the low to mid 90s for the weekend. Lows fall back into the 50s and 60s, so much more comfortable at night.
