FIRST ALERT: Several rain chances through the weekend
MYRTLE BEACH, SC (WMBF) - Just a stray shower remains possible on Thursday before two systems deliver more significant rain headed into the weekend.
An onshore flow will continue to increase moisture across the region on Thursday with mostly cloudy skies at times. Despite the increasing moisture, rain chances are slim with just a 20% chance of a stray shower or two during the afternoon.
Temperatures will be mild again on Thursday with the lower 70s along the beaches and the middle 70s inland.
UNSETTLED WEATHER LATE WEEK
Two more organized storm systems are still forecast to impact the Grand Strand and Pee Dee on Friday and again on Sunday. Models continue to struggle with the timing and rainfall amounts of both systems.
Based on the latest data which has sped up the timing on Friday’s system, rain will likely overspread the area before sunrise on Friday. The best chance of rain will continue through the morning commute but will then come to an end by midday.
A bit of sunshine is now likely by Friday afternoon, but the added sun could energize the atmosphere enough for a few isolated late day showers and storms.
Temperatures will be warm with readings in the middle 70s at the beach and upper 70s to near 80 inland.
The first low pressure system will move offshore by late Friday night with dry air returning for the first half of the weekend.
Saturday’s forecast looks lovely. Highs will be in the upper 70s to lower 80s with dry conditions for any Saturday plans.
The second system is set to impact the Carolinas on Sunday, but the track of the low pressure system will determine how much rain the region sees along with the risk of any strong storms. The latest data suggests that any severe storm threat will be quite low, but periods of rain are looking likely through the day on Sunday and some periods of heavy rain may develop as well.
As a result of the latest data, the rain chances for Sunday have been bumped up to 60%.
Rainfall totals from Friday through Sunday night will likely average one to two inches across most of the region.
