Storm Center Update – Tuesday PM July 5


It has been a hot and muggy day in eastern KELOLAND. Temperatures have risen into the 80s to low 90s with tons of humidity. Dew points have climbed into the low 70s in SE South Dakota, so it will be muggy the remainder of the day.

When you get heat and humidity and a trigger (a boundary lingering in the atmosphere from thunderstorms earlier today) the result is often severe weather. The Storm Prediction Center has issued a Tornado Watch for NE South Dakota through the evening hours – though the greatest threat for the South Dakota counties will probably be within the next few hours.

Otherwise, thunderstorms will be in the forecast into the early evening, with hail and strong winds possible. Overnight skies will clear out, with overnight lows in the upper 50s to mid 60s.

Tomorrow will be a similar setup, though we may have a bit less humidity and temperatures may be a few degrees colder, in the 80s. But an area of low pressure will slide from west to east across KELOLAND, causing more late-day thunderstorms to fire. Some of those could be strong or severe.

Depending on how the atmosphere gets worked over by those storms, we could be in for a bit more widespread event on Thursday, with temperatures again in the 80s.

We expect things to quiet down a bit for Friday (other than a little leftover morning activity) and Saturday. Highs will be in the mid-80s, near normal for early July. Sunday will be in the same ballpark, with at least a chance of some morning storms.

We expect this near-normal temperature pattern to continue into early next week, with the usual July-normal chances of thunderstorms.
