A Sunny, Warm Start to the Week

Monday, August 19, 2019

It is the first week of school for a lot of kids and we are off to a relatively quiet, summery start. Today will be mostly sunny, warm and humid with temperatures ranging from the mid to low low 80s in Sioux Falls to the mid to upper 80s along the James River to the low 90s across central South Dakota. Scattered thunderstorms are possible along the James River late this afternoon into this evening with storms redeveloping along and east of I-29 late this evening and overnight tonight. The overall severe weather threat for later today and tonight is low, however, one or two storms could produce marginally severe hail, straight line wind gusts or even a weak tornado.

After one more warm, humid day tomorrow, cooler air will arrive and take us comfortably through the rest of the week. Wednesday, Thursday and Friday will be mostly sunny with below average high temperatures in the upper 70s to low 80s.

Scattered thunderstorms are back in the forecast for late Friday, Friday night into Saturday morning. After that, the rest of the upcoming weekend is looking good. Saturday and Sunday will be partly cloudy with just a slight chance of a random, isolated thunderstorm. Highs will be slightly warmer – in the low to mid 80s – this weekend.

A Sunny, Comfortable Start to the Week

Monday, July 29, 2019

Our weather is going to be quiet and comfortable for the last few days of July. Today and tomorrow will be sunny with below average high temperatures in the upper 70s. After an isolated thunderstorm or two on Tuesday night, Wednesday will be slightly warmer and just a bit more humid.

Thursday will be right on par for the first day of August. Partly cloudy and muggy with high temperatures in the mid 80s. Friday will be partly cloudy with a chance of thunderstorms in the morning and again in the afternoon and at night.

Weather for the upcoming weekend is looking fantastic. A few lingering thunderstorms are possible Saturday morning, then it will be partly cloudy, warm and humid with high temps in the low to mid 80s.

Storms Today… Sunny, Not Humid Tomorrow

Tuesday, July 09, 2019

Today will be warm and humid with scattered storms. In Sioux Falls, the best chance of storms will be this morning as scattered thunderstorms move across much of central and eastern South Dakota into Minnesota and Iowa. Another line of storms will develop across northern and northeastern South Dakota this afternoon with yet another line of thunderstorms possible across western and central South Dakota late this afternoon into this evening. The last line of storms will dissipate as it moves east overnight.

As I mentioned, today will be warm and muggy. High temps will be back in the mid 80s with a dew point in the low 70s. That will pull the heat index back into the low 90s this afternoon.

A cold front will slide east of our region overnight, taking the heat, humidity and storms along with it. Wednesday will be windy and cooler with high temps around 80 degrees. Thursday will be sunny and warmer but still not terribly humid.

Enjoy the break from the heat and humidity on Wednesday and Thursday, because the summer sauna will be cranked to the maximum all weekend. High temperatures will reach the upper 80s to low 90s with the heat index approaching 100 degrees on Friday, Saturday and Sunday. The weekend will be mostly sunny with just a slight chance of a random, isolated thunderstorm.

I don’t think we’re going to get much of a break from the heat, either. Long range models suggest that the warm, humid pattern will last well into next week.
