COLUMBIA – Confidence continues to build that tropical system Isaac will track across the region and bring heavy rainfall to the Columbia area Friday and Saturday.
In a special statement issued at 3 p.m. Tuesday, the National Weather Service said "weekend rainfall totals of 2 to 4 inches are possible with locally higher amounts."
According to the statement: "The rain may be heavy at times Friday night and Saturday as the center of the tropical system moves northeast across Missouri and Illinois."
The weather service is projecting a 50 percent chance of rain Friday, 70 percent chance Friday night, 60 percent chance Saturday and 40 percent chance Saturday night.
Scott Truett, who works in the St. Louis office of the weather service, said that in order to make a dent in the drought, rainfall would need to reach 9 to 15 inches over the next few weeks.
In spite of the drought, Truett said the system could bring enough rain to cause rises in streams and rivers during the Labor Day weekend, and he said campers and others should be aware of changing conditions.
