Not Much Storm Development Today: Even though an isolated storm is possible through late evening, most towns will remain dry this evening as temperatures cool into the 70s and then 60s overnight.
Sunday Scattered Storms: A weakness in the upper wind flow cruises in tomorrow and will be just enough of a spark to make more scattered rain and storms happen during the afternoon and evening. Still, widespread rain isn't expected. Highs on Sunday will reach the 80s.
Summer Expectations - Heat Versus Humidity: I realize it's no ground-breaking revelation to let you know that recent heavy rains have put a large quantity of water in the soils of the Upstate, Western NC and NE Georgia. It's also no secret that we haven't seen much high heat at all so far for May and June. Since the start of Summer is just a couple of weeks away, you may be wondering what sort of heat is ahead for us and if we will deal with any consistent heat waves.
Interestingly, recent heavy rains and even more importantly the backlog of water we have accumulated since last Fall will play a key role in whether we endure lots of heat or more so just a lot of humidity and some inconsistent high heat this summer.
Looking back at similar wet springs (one last year) gives us some idea as to what sort of temperatures and humidity levels are on the way once the saturated soils are taken into account.
With the abnormally wet conditions during the last several months, the only heat wave we'll see with this much moisture in the ground is inconsistent heat below 94°-96° with very high humidity. Keep in mind that many people confuse a heat wave with high humidity. They aren't the same thing. Consider how much work the sun has to do in evaporating high ground-moisture content before true heating can begin.
In the end, we will have some days where temperatures go above 94°-96°, but odds are favorable for short-lived heat waves instead of any 95°+ lasting heat due to all of the evaporation and high ground-level moisture.
