More showers and thunderstorms are forecast for Thursday afternoon as a warm and humid atmosphere remains firmly in place across the area. Temperatures will warm to the low-to-mid-90s before storms start to kick up after convective temperatures are met. Shear is weak and instability is about average, but there will still be plenty of moisture to wring out of the atmosphere, so expect frequent lightning and heavy rain with the stronger of Thursday’s thunderstorms. There will be the risk for storms to anchor a bit and rain a lot in one spot as westerly flow aloft fights against an inland-moving seabreeze. (Daniel Island knows all about this, with several stations on the island recording 2-3″ of rain in a couple hours’ time.) A damaging wet microburst or two can’t be discounted either especially near where outflow boundaries collide. Once again, keep an ear out for warnings and take it easy on the commute.

One more round of coastal flooding is possible with the Thursday night high tide at 11:43 PM. Expect water levels between 7.1-7.3′ to produce some minor flooding generally between 9 PM-1 AM. A Coastal Flood Advisory will likely be issued. From there, the astronomical influences of the full moon will wane further, and while water levels may get close on Friday night, we should be done with this round of king tides.

Friday & the weekend: More of the same

Copy-and-paste weather continues into the weekend. Expect temperatures to generally top out in the low-to-mid-90s each day before thunderstorms develop along and ahead of the seabreeze in the afternoon. Some thunderstorms may produce heavy rain, frequent lightning, and gusty winds. Not everyone will get the same amount of rain — and some of you may stay completely rain-free some days. Heat indices on Friday will top back out around 106°, which will elevate the risk for heat stroke before storms fire. Similar heat indices can be expected as we head into the weekend. Bottom line: It’s no total washout by any stretch, but be ready to have outdoor activities move indoors at a moment’s notice.
