While meteorological fall begins on September 1, summer will blaze on in the Lowcountry over the next several days as we remain within a warm and humid airmass. Showers and thunderstorms will be possible each afternoon along the seabreeze and other outflow boundaries generated by thunderstorm activity. As we head toward the weekend, a nearby frontal boundary could aid in additional showers and thunderstorms. We could see temperatures come down a little bit for Sunday as winds turn more onshore, but showers and storms remain in the forecast.
After what was an uncharacteristically wet and cloudy weekend across the Lowcountry, we will gradually move back into a more typical late-summer regime of afternoon thunderstorms and temperatures reaching the low 90s for the upcoming work week. But first, we’ll need to deal with a higher-than-normal risk for additional showers and thunderstorms on Monday, with potentially heavy rain having impacts starting early in the morning.
We continue to watch Hurricane Marco and Tropical Storm Laura as they continue on an unfortunate course to delivering a 1-2 tropical punch to parts of the Gulf Coast next week. Aside from some enhanced moisture funneling into the area from the storms around the western side of the Atlantic ridge through Monday, it does not appear that Marco or Laura will have any impacts in our area. We are now in the peak of the season, though, and we’ll want to keep a close eye on any waves that meander into the Atlantic from Africa for development over the next few weeks. Stay tuned…
After a brief respite from suffocating humidity today — the overnight temperature dropped to 69°, according to NWS, the coolest since June 20’s low of 67° — we will see rain chances return to the forecast as the upper trough which has kept things quite unsettled remains in place for the next few days. Brief bouts of heavy rain will be possible once again, but it won’t rain all the time or even every day at one particular spot. As we get into the weekend, Atlantic high pressure looks to build back into the area, which will help tamp down the overall coverage of storms (and begin sending temperatures back upwards a bit).
High pressure in the Atlantic and low pressure inland will keep the squeeze on for showers and thunderstorms each afternoon this week. Temperatures will top out in the upper 80s to around 90° each day before the onset of thunderstorms cools some of us down.
Thunderstorms will move slowly and thus have the potential to put down some pretty good rainfall, especially as we start the week, so be ready for localized flooding where storms set up. Lightning will certainly be a hazard as well, but the threat for severe weather otherwise remains low (though a wet microburst can never be ruled out).
We continue our midsummer heat, humidity, and thunderstorm chances as we close out July and head into August. Temperatures will continue to run in the low 90s each day; heat indices will top out in the low to mid-100s in the afternoons before the onset of thunderstorms. After more isolated coverage on Monday, expect an uptick for much of the rest of the week with a little upper-level support getting in on the action. Some of you who have been on the “miss” side of the “hit-or-miss” thunderstorms these past few days will have plenty of chances to get a free lawn watering in the upcoming week!
Stop me if you’ve heard it: We’ll see highs in the 90s, heat indices in the 100s, and a chance of thunderstorms pretty much every afternoon along and inland of the seabreeze. We might see a little uptick in shower and storm activity as we head toward the weekend as models suggest a little mid-level energy trying to work its way in, but we’ll keep an eye on this trend. Stay cool and masked up!
We will find ourselves firmly in a slightly unsettled summertime pattern for much of the week. Highs will top out in the low to mid-90s each day, with heat indices in the low to mid-100s in the afternoons. Showers and thunderstorms will be possible each day. It won’t rain all the time, and you probably won’t see rain every day, either. Mind the heat — take frequent breaks in the afternoon, get plenty of fluids, and seek out air conditioning when you can. Don’t forget to wear a mask!
We’ve got a soggy, stormy start to the week in store as a low pressure system moves through the Gulf Coast states and strafes our coastline. We’re already starting to see some shower activity from this storm system this evening, and more is expected through at least Wednesday night, if not beyond.
We’ve got a fairly active week of weather ahead as we move toward Independence Day this weekend. First off, the warmth: Temperatures will push the mid-90s on Monday and Tuesday, and the humidity will push heat indices well into the 100s. Could scrape 105° at times, so be sure that you are hydrating well and taking plenty of breaks if you’re outdoors.
Thunderstorms will feature prominently in the forecast this week as we remain in northwest flow aloft Monday and Tuesday. This will allow thunderstorm complexes to move into the area from the northwest, potentially packing strong winds and heavy rain. Thereafter, a trough of low pressure aloft and at the surface will keep us in a fairly unsettled pattern, with showers and thunderstorms possible each afternoon with peak heating. This pattern may last into the weekend, so be thinking about indoor alternatives to your July 4 plans now, just in case. Will keep an eye on it to see how things evolve throughout the week. Stay tuned.
The solstice must have kicked something into alignment, because this week fits perfectly into the normal summertime routine with temperatures running in the upper 80s to low 90s each day and a chance of thunderstorms each afternoon. Could see some additional coverage of showers and storms Wednesday and Thursday, but other than that, it’ll be a typical Charleston summer setup. If you’ve got outdoor plans, just keep an eye on the weather each afternoon. When thunder roars, go indoors!
