The Winds Return.......A Little.

Over the past few weeks, the winds in South Dakota have been pretty calm, at least for our standards. Considering we are the 4th windiest state in the nation, you don't expect to go a few weeks without seeing a few windy days. Well, it looks like things are going to return to normal through the end of the week as the breezy conditions have finally returned. Winds should be sustained anywhere from 10-20 mph over the next couple of days and areas of the northeast could get gusts to 30 mph. Here is a quick look at the probability of seeing sustained winds of at least 15 mph over the next 3 afternoons.An even more noticeable aspect of the weather this week though will be the temperatures. They will be below average for much of the state right through the weekend.

Storms Around The Area

In the Sioux Falls area we saw a brief bit of rain just a few minutes ago - but the heaviest rain was seen toward Brookings and farther toward the East and Southeast...



That video above from shot as the storms were circulating around the area... and you can see how much the southeasterly breeze really picked up about that time.

Looking a little bit farther toward the North you could see the storm affecting the Brookings area:

Quite a storm. We'll be watching for any more to move in - but for now expect most storms toward the North and the West to be done. Drier air is moving in quickly - and as that happens the chance for storms diminishes.

Have a great night!

Drier Air Moves In

As storms continue to develop this morning, the cold front that looks like will mark an end to our severe weather possibilities (at least in the near term) is making its way through western South Dakota. The main reason this will happen is drier air will be working its way in tonight and tomorrow. Notice that at 7am this morning, dew points still into the 60's and low 70's across the state.But once that cold front begins to work its way east, it takes the moisture with it. So by tomorrow evening, dew points will be drastically lower in the 40's and low 50's which will make it feel much more comfortable outside.
With this cold front and drier weather, it is not going to feel much like July outside so enjoy it while it lasts.

Storm Update... Severe Weather In Beadle And Jerauld Counties

We're watching as the lone storm to move east river so far is moving through the Beadle and Jerauld county regions...

So far large hail seems to be the deal with this storm, but we'll continue watching this one and all of the others out there as well.

Storms Again Tonight...

Make sure you stay tuned, and during the calm periods we'll get you up to date on the storm situations around the region.

Right now we have a tornado warning around the western South Dakota area, and we've been following it for a little while now. We'll be watching for more storms to move into the area as we head into the overnight hours, so don't be surprised to see a storm by morning even in the far eastern portions of our viewing area.

This is the latest image from 4:20pm:

That purple polygon is a tornado warning. We'll continue to watch this, and just continue to stay tuned to KDLT tonight at 6 & 10pm, and we'll update you on the situation.

Weather Continues Active Streak

Continuing to be quite active across the state again today as we have the possibility of more severe weather. Areas west river have the best components for severe weather today and the tornado potential is up to 10% percent as seen in the picture below.Now, don't let your guard down across the east either though because large hail and damaging winds are still likely. This severe weather will likely start in areas of the west as supercells and then move eastward through the overnight and form a line of thunderstorms that pushes through our eastern areas. Heavy rain could accompany the severe weather as seen in the forecasted rainfall amounts below.So buckle your seat belt because the next 36 hours could be a bit bumpy.

Severe Risk Starts the Week

After our very quick bout of severe weather early this morning, we've got another round on the way for tomorrow. The day will start out calm, especially in the East - plenty of sunshine and a relatively humid day. In the afternoon is when severe weather will spark up in the west and move eastward throughout the evening hours, mainly after 8pm. (I honestly don't know why they didn't put a moderate risk in western and west-central SD due to all of the energy that's going to be available tomorrow, but this active weather pattern is really tricky to pinpoint what's going to happen when) The main threat is going to be hail and wind with this system, tornadic cells are more of a possibility in western and central SD. As a cold front swings through, winds will switch to being from the north, and they'll pick up, pushing this system, rain and storms included, out of our area by 1pm on Tuesday. The east will see the rain mainly overnight on Monday (thunder and lightning definitely going to be going on as this system moves) and sticking around through Tuesday morning.

Cody and Aaron will give you more updated information tomorrow as things unfold, so keep checking in.

Tornadic Cell in ND moving into SD

Currently watching one little tornadic cell in North Dakota - the pink polygon is the tornado warning for Grant county until 8:45pm MDT. This particular cell is a doppler radar indicated severe thunderstorm, but a tornado did briefly touchdown and then went back up into the clouds at roughly 6:58pm.


This is the storm relative velocity(SRV) - you can see there's a pretty bright green (area of motion towards the radar which is located near Bismarck) right next to the red (area of motion away from the radar) Basically the SRV looks relatively similar at each cross-section of the storm which means that there is rotation in this storm.
The whole cell is heading towards McIntosh, SD in Corson county - plus we have more severe storms to our south... expect the area between this cell in ND and the storms to our south in NE to fill in for some late night storms and showers.
More severe weather is expected south of I-90 tomorrow and a broader area of severe risk is in the forecast for Monday... we'll keep you informed of all the details of course. More information on the severe threat tomorrow as I think that most of Sunday's severe weather will be further south than in our neck of the woods.
