Saturday looks to be somewhat unsettled, particularly in the afternoon, as a cold front approaches the area from the west. We’ll start in the mid-70s, warming to the low 90s in the afternoon before thunderstorms get going. These storms will keep us out of Heat Advisory territory, with heat indices generally peaking around 101-105°, highest near the coast and in downtown Charleston. This is below the Heat Advisory criteria of 108° for two hours — the first time since August 11 we may get through a day without heat headlines! From there, expect showers and thunderstorms to get going, with periods of heavy rain and frequent lightning at times. The risk for storms should continue through the evening, diminishing as we get past sunset.
Overall, unsettled weather will continue over the weekend, though as is often the case in the summer, your plans won’t be completely washed out, either.
High pressure will give way to a cold front approaching from the west, bringing more humid air and shower and thunderstorm chances back to the forecast for the weekend.
A stalled front will continue to contribute to shower and thunderstorm chances through the weekend, particularly on Saturday as a trough aloft swings through, providing a little extra “oomph” to budding updrafts aspiring to be efficient rain-makers.
Midsummer heat and humidity will not relent this weekend with temperatures continuing to run above normal courtesy of Atlantic high pressure pumping warm and moist air into the area while high pressure remains resident aloft for a few more days.
After another 99° day at the airport, we’ll take one more run at the century mark on Saturday before a front drops toward the area on Sunday, bringing about more unsettled weather that will keep temperatures a little more in check.
A hot weekend is ahead, especially on Sunday, as high pressure builds in aloft. A few of us could get some relief from a few thunderstorms, but that’s not a guarantee for everyone.
Heat, humidity, and chances for afternoon thunderstorms continue into the weekend, with the potential for not only record high temperatures but also record warm low temperatures each day.
This weekend will be warm and a little more humid as surface high pressure moves into the Atlantic, sending winds more southerly behind it which turns the moisture tap back on. We should stay quiet, though, with ridging aloft and a pretty solid pocket of dry air hanging in there for a couple more days. We’ll see some clouds at times, particularly of the high variety, but otherwise expect plenty of sunshine to still break through for the weekend. Temperatures Saturday start in the mid-60s, warming to the low 90s in the afternoon, while Sunday feels much more like summer with a low around 70° and highs in the low 90s.
Rain chances gradually return as we get into the start of next week; these will generally be of the popup variety. Highs Monday top out in the mid-90s, while upper 80s to around 90° will be more common through the middle of next week.
Rain spreads back into the Lowcountry on Saturday as a stationary front buckles back northward across the area. A bit of upper-level energy will also kick in some lift, and that’ll result in scattered to numerous showers and thunderstorms at times on Saturday. Right now it looks like the best chances will be found in the morning through early afternoon hours, but a shower or storm just can’t be ruled out during any part of the day. Temperatures will start in the low 70s, warming to the mid-80s in the afternoon at best.
