Charleston, South Carolina – A drier late-winter pattern is expected to take shape across South Carolina heading into early March, increasing the probability that rainfall totals trend below seasonal averages during the Feb. 28 through Mar. 13 timeframe.
According to the National Weather Service Climate Prediction Center, much of South Carolina carries a 40% to 50% probability of below-normal precipitation in the Week 3-4 outlook. The drier signal spans the Interstate 95 corridor from Florence to Walterboro, west along Interstate 26 through Columbia to Spartanburg, and across Interstate 20 toward Aiken.
This extended-range guidance favors a more suppressed storm track across the Southeast, limiting the frequency of organized rain-producing systems compared to late-February norms. While isolated systems remain possible, the broader atmospheric pattern suggests fewer widespread soaking events.
Temperatures during the same period lean near to slightly above average statewide, reinforcing a trend toward more typical early-spring conditions without prolonged cold-driven precipitation events.
Communities from Charleston and Myrtle Beach to Columbia, Greenville and Rock Hill fall within this drier signal. The Week 3-4 outlook reflects large-scale atmospheric trends rather than specific storm timing or daily rainfall amounts.
Additional refinements are expected as the late-February to mid-March window approaches and shorter-range guidance provides greater clarity on any developing systems.
