Another hot summer day lies ahead for Tuesday, with just a few of us possibly seeing some relief from thunderstorms in the afternoon. We start the day in the mid-70s, warming to the mid-90s in the afternoon. Dewpoints in the low to mid-70s will make it feel closer to 103° at times, with even warmer heat indices possible in the wake of the seabreeze.
As mentioned, a few thunderstorms will be possible with a stalled front in the area, but not everyone will see a storm. A stronger storm or two can never be ruled out this time of year, but there is not a widespread risk for severe weather.
Charleston summer is in full swing as we get into the last week of June as hot and muggy conditions will be prevalent for the foreseeable future.
Monday will be particularly warm with westerly winds ahead of a front that’ll be sagging southward throughout the day. This front along with the pinned seabreeze should help ignite some showers and thunderstorms in the afternoon, but not everyone’s going to get heat relief. We start the day in the mid-to-upper 70s, warming to the upper 90s in the afternoon with heat indices around and even a little above 105° expected. (Note: 105° used to be heat advisory criteria, but that has changed this year — 108° heat index or higher for two hours is the new heat advisory criteria.)
The front hangs around Tuesday before retreating northward Wednesday. This should generally lead to standard afternoon thunderstorms along and ahead of the seabreeze each day. Highs continue in the mid-90s after mid-70s starts both days, with heat indices once again potentially approaching 105°. Rain chances tick up Thursday and Friday as a disturbance moves across the area, while ridging builds aloft for the weekend and starts to reduce afternoon storm chances. Highs continue in the low to mid-90s each afternoon after mid-70s starts, with heat indices flirting with the Heat Advisory criteria especially later in the work week. Be sure you’re taking frequent breaks and hydrating if you’re working outdoors in this swampy weather!
The tropical low — but not depression — that’s been driving Friday’s periods of rain will be ashore in far southern Georgia by Saturday morning. It’ll start to turn more northward throughout the day, and that’ll help instigate showers and thunderstorms Saturday afternoon. Outside of storms, expect a warm and muggy day with highs topping out around 90°.
We’ll keep the risk for showers and a few thunderstorms in the forecast for Sunday as well, with the best chances once again in the afternoon (though a few showers or storms could be around all day). We stay muggy, with lows in the mid-70s yielding to low 90s in the afternoon that’ll feel more like the upper 90s.
Humid days are here again: tropical moisture associated with a disturbance (which might become a tropical depression before coming ashore in Georgia tomorrow) will overspread the area, with showers and a few thunderstorms expected for a fair bit of the day as a result. It won’t rain all day at any one location — the rain will generally be off and on and be moving fairly quickly — so generally expect a half-inch of rain in most spots. A few locations could see locally heavier rainfall in the wetter storms. Thankfully, severe weather and flooding don’t appear to be major issues this go-around. Temperatures start in the low 70s, warming to the upper 80s between storms. It’ll be a muggy day as dewpoints surge into the low 70s by morning, with heat indices in the mid-90s expected.
High pressure gets into a typical summertime configuration starting Saturday, and we’ll definitely be feeling it as lows bottom out only in the mid-70s. The 90s return Saturday afternoon and will have some staying power through the weekend and well into next week, too. Showers and thunderstorms will be possible each afternoon along and ahead of the seabreeze, with locally heavy rain possible but severe weather generally not expected. Just be ready to bring outdoor activities inside if a thunderstorm approaches your location.
