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!
It sure has been cool and occasionally rainy over the last few days! Today’s high only made it to 77° at the airport, which barring an unforecasted heating episode will be a new record low maximum temperature for the date. The previous record low max for June 14 was 78° set in 1939. This cool pattern is thanks to an upper low aloft and a wedge of high pressure at the surface. Moisture riding atop the wedge is keeping cloud cover and the occasional showers around, and this will continue for a couple more days before the pattern turns more summer-like by the end of the week.
Periods of heavy rain will continue for much of Monday before winding down in the evening. Once again, temperatures will run well below normal (upper 70s) thanks to cloud cover and rain-cooled air. While we’ll have less rain on Tuesday, we will have one more day of cool temperatures with continued cloud cover and northerly winds on the back side of a coastal low. Before it’s all said and done, another 1-3″ of rain may have fallen across the area in what has been a wet year — we have a 6.2″ surplus of rain at the airport.
As we get into mid-week, we’ll begin to see the upper low finally take leave of the area, allowing the surface low to go with it. Showers will continue to be in the forecast, but temperatures will moderate into the lower 80s. By the end of the week and into the weekend, expect temperatures to head back into the upper 80s and lower 90s with the typical afternoon thunderstorm regime we all know and love during summers in Charleston.
June in Charleston is typically characterized by afternoon thunderstorms and highs in the upper 80s, and this week will not disappoint in either department. We’re caught between Atlantic high pressure and the broad circulation of Tropical Storm Cristobal, putting us within a corridor of deep moisture which will help drive scattered showers and thunderstorms each afternoon to start the week. All the while, a stalled frontal boundary will be hanging around to our north, meandering for the next several days and acting as another focal point for showers and storms. As we get into the weekend, another front approaches. As we so often see in the warm season, though, the front looks to have a hard time getting through the area, keeping us in the soup with scattered afternoon thunderstorms through Sunday.
Monday and Tuesday sure won’t feel like June in the wake of a cold front that came through earlier today. Cool high pressure will wedge into the area, and the resulting onshore flow will keep temperatures rather pleasant and cloud cover reasonably low to start the new work week. We’ll begin a warming trend on Wednesday with a return to the 90s by Thursday. Next rain chances arrive by this weekend.
Some much-needed rain is in the forecast for much of the upcoming week as a cold front with an accompanying upper low moves through the area. Said upper low will then stall out over the Southeast into the end of the week, keeping thunderstorm chances around and temperatures a little below normal. As the upper low shifts away from the area toward Friday and the weekend, we’ll see rain chances decrease and temperatures approach the 90° mark. Overall, expect around an inch of rain before the week is over, with locally heavier amounts possible in thunderstorms — a healthy amount of rain, but not all at once, thankfully.
