After a reasonably quiet Friday, shower and thunderstorm chances return to the forecast for the weekend, bringing with it a decent shot at some much-needed rain but also the risk for a strong storm or two on Saturday.
May Day will be a partly cloudy affair across the Lowcountry as Atlantic high pressure continues to exert influence over our weather. We’ll start near 60° away from the locally warmer coastline, warming to the mid-80s in the afternoon. It’ll be a bit breezy especially as the seabreeze gets by in the early afternoon, but otherwise no major concerns are expected.
High pressure moving offshore will help send winds a little more southerly for the rest of the work week, and temperatures will respond with a subtle bump into the mid-80s each afternoon. Expect mostly sunny skies to prevail on Wednesday; lows in the upper 50s warm to about 85° in the afternoon, except a little cooler near the coast where the cooler Atlantic waters will modulate the high temperatures a bit.
Another seasonably warm and mostly sunny day is on tap for Tuesday as high pressure remains in control. We’ll start the day on the cool side of normal once again, with lows in the mid-to-upper 50s expected away from the coastline. Then, temperatures warm to the low 80s in the afternoon with plenty of sunshine throughout. Don’t forget the SPF!
We will still need to monitor tides in the late evening as water levels should peak between 7-7.2’ mean lower low water in Charleston Harbor a little before 10:30 PM. Some minor salt water flooding will be possible an hour or two around the time of high tide as a result, and another coastal flood advisory appears probable. This should do it for this high tide cycle, though, as astronomical influences wane and winds turn more unfavorable starting Wednesday.
High pressure will be the main weather feature for the next few days, with comfortable warmth and plenty of sunshine expected through Thursday before the next isolated storm chance arrives Friday.
