MYRTLE BEACH, S.C. (WBTW) — Thunderstorms pushed through the Pee Dee and along the border belt last night and there were some notable rainfall totals and even a record-breaking amount. Lumberton broke the record for daily rainfall accumulation yesterday. The previous record was only set just last year and was 2.07″. Lumberton reported 3.36″ yesterday which was much needed.
Rain will continue to be the main headline for today, but luckily it will not be as hot. No heat advisories are in place for today. Florence is still projected to feel like 100 degrees today, but the beaches will feel like the mid-90s. High temperatures today will be in the upper-80s for the Grand Strand and low-90s inland,
The first half of the day is going to be uneventful, so beachgoers can probably get a couple of hours at the beach until late in the afternoon. Be mindful, that there is an advisory for dangerous rip current risks, so always swim near a lifeguard.
Rain is expected to fire up this evening as a cold front begins to drop down through the area. Current model runs show this as a scattered rain event with isolated periods of heavy downpours. Stray showers continue to be present into the overnight hours and temperatures will bottom out in the mid-70s.
A fairly similar rain setup will be in place for tomorrow, but with slightly more coverage. There will be periods of very heavy downpours and with all the rain this weekend it is likely there will be some localized flooding in low-lying and poor drainage areas. 1-2″ could be seen in the next 48 hours.
The cold front will pass through Sunday morning. New forecast models show the cold front and associated low-pressure system more to the south, so temperatures have adjusted for tomorrow to be even cooler. High temperatures in the low to mid-80s are widespread, but the humidity will still be quite oppressive.
Heat-driven showers and thunderstorms will take up most afternoons in the upcoming seven days, but another slight cooldown will be associated with a cold front midweek. The temperatures will be slightly below normal until Tuesday. For this time of year, 92 degrees is normal in Florence and 88 is normal in Myrtle Beach. The hottest day will be Wednesday near 90 degrees for the beaches and mid-90s inland, possibly looking at a heat advisory for that day.
