Monday's forecast: Turning unsettled...then staying that way
Hello everyone, Jared Smith here with your Charleston weather forecast for Juneteenth, Monday, June 19th, 2023, as well as what looks to be an unsettled week of weather ahead.
We start Monday generally on the quiet side, with lows bottoming out in the low 70s away from the locally warmer coastline.
Temperatures will warm into the mid 80s in the afternoon, but mix in the humidity and it’s going to feel closer to 90.
Showers and thunderstorms should then fire up, perhaps as early as midday, along outflow boundaries in the sea breeze as some energy aloft moves by at the same time.
Expect pretty decent coverage of showers and storms through Monday afternoon and evening, with some pockets of heavy rain possible at times.
A strong or severe thunderstorm or two can’t be ruled out either, with the potential for some strong wind gusts and maybe even some hail too.
We keep this highly unsettled forecast in place as we get into the meat of the work week too.
A Rex block pattern, similar to what kept Memorial Day weekend quite chilly and rainy, will set back up over the area once again.
This will keep numerous showers and thunderstorms in the forecast for much of the rest of the week, while temperatures will run at least a few degrees cooler than normal.
Generally expect mid 80s each afternoon.
No, we’re at least not dipping back into the 60s though.
The block should break down by the weekend, but plenty of gulf moisture will continue to stream into the area, keeping the atmosphere very ripe for numerous afternoon and evening thunderstorms through about Sunday.
And finally, look at the tropics, which are getting a little busy.
As of the 8pm outlook on Sunday evening, Invest 92L has been giving a 90% chance of becoming a depression, and could do so before we go to bed on Monday.
It’s still really early in the ballgame with this one, but we’ll keep an eye on it as it moves west-northwest towards the Leeward Islands over the next few days.
A secondary of interest is now being monitored by the Hurricane Center in the wake of 92L, and this one is south of the Cabo Verde Islands and has a 20% chance of tropical development over the next week.
Both of these systems currently don’t pose any threat to us here in the Lowcountry.
If that should change, however unlikely, I’ll let you know.
And yes, it is weird that we’re talking about tropical development in areas we typically reserve for late August or September.
But when sea surface temperatures in the eastern and central Atlantic are running well into the 80s, it’s no wonder we’re seeing a few storms here and there try to spin up.
And that was Charleston Weather Daily for June 19th, 2023.
I’m Jared Smith.
