The good news is that there are some predominantly rain-free days in the forecast this week. (Imagine writing that three weeks ago!) The less-than-good news is that temperatures will head back up, with heat indices perhaps approaching 110° later this week before a slightly more unsettled pattern returns for the weekend.
Rain continues to factor into the forecast on Monday, with another round of showers and storms possible at the coast in the morning. Interestingly, the HRRR model is depicting a line of showers and storms to develop as early as 4am from Edisto to Jamestown. Will be interesting to see if an idea like that verifies, but regardless, there could be some weather to deal with as we commute Monday. The seabreeze takes command in the afternoon, with another round of scattered storms possible heading into the evening hours.
High pressure at the surface and aloft will subsequently strengthen, decreasing our rain chances for the middle portion of the work week and turning up the heat as a result. The 90s will be steadfast, with humidity driving heat indices into the low 100s on Tuesday and closer to 105-110° Wednesday-Friday. The ridging aloft will help suppress thunderstorm development, though you can never totally rule one out this time of year.
We’ll begin to see another mid-level “TUTT” low approach the area over the weekend. This will help weaken the ridging a little, allowing for more normal 20-30% afternoon thunderstorm chances to return to the forecast. However, right now nothing more than scattered coverage is expected. Temperatures will remain warm, with low 90s expected each afternoon through Sunday.
Weather support for a good cause
I’m proud to announce that @chswx will be providing weather support for this year’s Lowcountry Golf Marathon on August 8. This event will benefit Folds of Honor, a charity providing scholarships to the spouses and children of fallen or disabled service members. The golf marathon is exactly what you might think: nonstop golf from daybreak to sundown, featuring PGA pros and a wonderful colleague of mine, Jeanne-Marie Busuttil, who has played on the LPGA Tour! Please consider making a donation to help raise money for these important scholarships, and start the good vibes for a rain-free and unseasonably cool day. 🙂
