Warm and muggy conditions continue for the rest of the work week as high pressure ridges aloft and at the surface. This should help keep showers to a dull roar, though I suppose with the airmass we can’t ever totally rule out a rogue popup shower (like we saw today).

We may start Wednesday with some fog once again, but that should mix out by 9-10am to yield a mostly sunny day with highs in the low to mid-90s. Dewpoints in the low to mid-70s will combine with those air temperatures to make it feel closer to 105° in the height of the afternoon, so be sure you’re taking frequent breaks and getting plenty of water if you’re outside during that time.

We’ll keep this going Thursday into Friday, with lows in the mid-70s each morning yielding to highs in the low 90s each afternoon with just a few clouds from time to time. The stacked high pressure will give any enterprising updraft trying to become a shower a very, very hard time, and rain-free conditions are expected as a result.

Tropics: Waking up a little

In Sunday’s blog I mentioned that model guidance was starting to converge on the potential for low pressure to develop in the Atlantic basin later this week or early next week. This trend continued, and NHC highlighted an area in the central Atlantic for possible tropical development over the next week as a result. There’s no disturbance to hang our hats on just yet, which adds uncertainty to the forecast, but right now there is a 20% chance for something to get going between 35°W and 65ºW in the next seven days. Otherwise, the tropics remain rather quiet for this time of year, and there are no concerns for the Lowcountry for the foreseeable future.
