Rest of the work week: Turning soggy Wednesday and Thursday as a coastal low moves by
A coastal low will bring numerous showers and thunderstorms, some with potentially heavy rain, to the Lowcountry starting late tonight and peaking Wednesday into Thursday.
Expect Wednesday to be rather unsettled, with the expectation that many of us could receive 1-2” of rain with locally higher amounts. No severe weather is expected, but some flooding may occur where storms train over each other, and we’ll need to keep an eye on that. Temperatures will start on the warm side in the low 70s, but highs will be suppressed to rain-cooled upper 70s to low 80s.
Showers and thunderstorms continue Thursday as the low lifts away. We should see some breaks in the clouds at times, but the expectation is that we’ll still be in off-and-on storms for much of the day. Expect highs to once again struggle to the low 80s after we start the day around 70° due to the continued rain, some of which may be heavy at times.
The low departs Thursday night, and by Friday we start to turn to more of a traditional summertime afternoon thunderstorm pattern as the seabreeze pushes inland. It’ll be considerably warmer, with highs topping out in the upper 80s to near 90° in spots, and that could help kick off a few stronger storms as well. We’ll keep this going into the weekend ahead of a cold front, too, so be ready for outdoor plans to move indoors.
Tropical concerns?
The National Hurricane Center continues to monitor the aforementioned low pressure for the potential to take on some tropical characteristics as it moves northward. The risk is relatively low still, with the latest tropical outlook putting the odds at around 10% for this storm to start to make a warm-core transition, but it’s not zero and some models are a little more bullish on this taking place.
Regardless of tropical development, the impacts are the same — some breezy conditions at the coast and the aforementioned heavy rain spreading across the area. In other words, don’t worry about whether the rain will get a name or not — it won’t really make a difference in what we ultimately experience.
