Slight Risk Brings Scattered Flood Chance to Mississippi and Tennessee Valleys Tuesday
Mississippi and Tennessee Valleys
On Tuesday, November 3rd, into early Wednesday, November 4th, a Slight Risk covers portions of the Lower Mississippi Valley to the Tennessee Valleys, meaning scattered flash flooding is possible. Showers and thunderstorms will bring moderate to heavy rain, with widespread amounts of 1 to 2 inches and locally heavier totals centered from northwestern Alabama through Middle Tennessee into Kentucky. The heaviest rain may cause problems in poor drainage spots and city streets, especially where storms keep training over the same areas. Never drive through flooded roads.
Southeast Florida
Also on Tuesday, November 3rd, into early Wednesday, November 4th, a small Slight Risk sits over parts of Southeast Florida, so scattered flash flooding remains possible. Deeper moisture will support storms with efficient heavy downpours, and localized additional amounts of 3 or more inches are likely in spots. These rains could make ongoing flooding worse in urban areas and low water crossings. Stay off flooded streets and never drive through water covering the road.
Tennessee Valley
On Wednesday, November 4th, into early Thursday, November 5th, a Marginal Risk extends from the Tennessee Valley into the Lower Ohio Valley and Southern Appalachians, meaning only isolated flash flooding is possible. Storms from the previous period will likely keep going into the early hours, bringing a continued but lower threat of runoff in small creeks and urban spots. Any flooding should stay limited as the activity gradually eases.
Nationwide
On Thursday, November 5th, into early Friday, November 6th, the chance of rain heavy enough to cause flash flooding stays very low across the country. No risk areas are in place, so people can expect a quiet day without notable flooding concerns from excessive rainfall.
Southern New England
On Friday, November 6th, into early Saturday, November 7th, a Marginal Risk covers Southern New England, including New York City and Long Island, meaning isolated flash flooding is possible. A corridor of heavier rain may stall over the area, raising the chance of an isolated problem in urban spots or where rain persists longest, though most of the rain should be beneficial on dry ground. By Saturday any leftover rain in eastern Maine or near the lower Texas coast looks unlikely to produce more than an isolated issue at most.
