Storms subside as summer heat makes a return
Storm activity and clouds turn more isolated as temperatures rocket back to above-average levels
RAPID CITY, S.D. (KEVN)—Our forecast picture finally shows clearing skies as a disturbance, causing some strong storms to move out of the area. We are still watching a complex of storms in Wyoming that should move over the Wyoming/South Dakota state line close to sundown. These could be accompanied by not only some heavy rainfall, but some gusty winds and some large hail, at least on the WY side of things. As we have clouded up and had some activity develop over the area, those storms in WY will not have as much “storm fuel” to work with, so we should see them subside somewhat. For southwest South Dakota, the atmosphere seems better per our most reliable data, so some of that activity coming in from the west should be able to hold on into Fall River, Oglala Lakota & Bennett Counties. Other than that, skies finally start to clear tonight with
We do still have a Level 2/5 (”Slight”) Risk for some scattered severe storms for the aforementioned area in South Dakota as well as our NE Wyoming counties, effective until late tonight, so this is a heads-up that the large hail/damaging wind threat remains for storms to the west. An isolated spin-up tornado is possible with some of the cells that get out on their own and get rotating. However, that looks to be the smallest of the three risks of severe weather impacts.
The next two days, instability continues to show, allowing for isolated storms to remain possible both Saturday and Sunday. While severe risk areas are not in play for those days, we will monitor any changes since there looks to be plenty of heating of the day and instability, especially on Sunday. Other than that, much warmer temperatures are in play as a ridge of high pressure builds up from the south, pushing out clouds and sending that warmer air in. We should see lower to mid-80s everywhere out of the Black Hills (upper 70s for you there), with some upper 80s out in the southern SD Plains. Those upper 80s and even lower 90s should quickly expand in area coverage and include Rapid City on your Sunday. We at least cool down to the upper 50s and lower 60s each night from the weekend into the beginning of this coming week.
If you’re out and about Sunday and especially Monday, with the upper 90s in play for some in Wyoming and South Dakota, keep the heat in mind as a reason to hydrate and limit strenuous activities to the earlier parts of the day. This will get you out of the way of any storms should they form.
Looking out further into the next week, temperatures should hover around the mid and upper 80s with lows in the upper 50s to lower 60s. We’ll watch the end of the week for slightly lower temperatures, with even a shot of some storms returning by then.
