Weather Highlights: • Some potentially heavy rainfall is expected over the Mississippi Headwaters region Friday into Saturday. This will bring some much-needed precipitation to that region in extreme drought. • Tropical Storm Henri’s track is looking ominous for the New England coast. The threats for storm surge, wind, and rain impacts in portions of the northeastern U.S. remain a distinct possibility, especially over the Cape Cod region. 7-day QPF totals (through next Thursday morning): • Upper MS: ¼-2 ½” expected with the highest amounts possible over the area with severe drought. • Middle MS/Ohio Valley: ¼-1” forecasted throughout the region. Isolated higher amounts will be possible. • Lower MS Valley: ¼-2” expected across the region with the higher amounts of 2-3” possible over north MS and TN.
