The next Pacific system is marching across the country right on schedule. It brings with it winter weather north of the Ohio River, spring storms along the Tennessee Valley, and a line of showers with some embedded thunder along the Gulf Coast. Rain starts for us later tonight, and should done by lunchtime tomorrow. Then, it should be dry right through St. Patrick’s Weekend. The core of the system is over the Great Lakes, a deepening low that is intensifying as it tracks toward New England. The trailing front has not created any severe weather so far today as it moves away from the polar jet during the afternoon. Concern about our Georgia and South Carolina rivers continues. This system is moving fast and is being stretched out as it approaches the East Coast, so there's no need to worry about river flooding. All rivers have now crested. Many are already below flood stage, and the rest -- including the Ogeechee -- will clear warnings mid-week. It should be all sunshine for the Saturday's St. Patrick's Day parade. We will start each weekend day "cool" in the 40s, warming nicely to near 70 Saturday, and low 70s Sunday. Watch for stronger winds late in the weekend. The next system is due late in the day on March 18. Meteorologist John Wetherbee, CBM
