FLOOD FEARS

Submitted by Admin on

Widespread rainfall associated with a slow-moving storm system will be prevalent across parts of the Gulf Coast and Deep South and into the Ohio Valley and mid-Atlantic on Friday. Excessive rainfall could lead to flash flooding for some areas. Meanwhile, there is a marginal risk of severe thunderstorms, mainly across parts of central and southern Mississippi.

Widespread heavy rain from the Mississippi Valley and Southeast to the Mid-Atlantic, with flash flooding possible across the Ohio Valley...Wintry weather returns to portions of the Great Lakes and New England...Another round of rain and high mountain snow for the Northwest expected this weekend...

As significant moisture streams northward out of the Gulf of Mexico ahead of a surface cold front, widespread heavy rain across the Mississippi Valley, Southeast, and Ohio Valley this afternoon will spread into the Mid-Atlantic by tonight and throughout the day on Saturday. In addition to heavy rain, flash flooding may also be a concern across portions of the Ohio Valley tonight into tomorrow morning. On Saturday, this southern stream front will eventually merge with a northern stream front moving across the Great Lakes pulling the precipitation into the Northeast.

From the Great Lakes to northern New England, precipitation should fall as snow, with sleet and freezing rain expected across remaining portions of the Northeast and southern New England. By Saturday afternoon, a surface low is expected to develop along the New England coastline, and bring the
possibility for accumulating snows to northern New England and Maine Saturday night into Sunday.

Meanwhile, out west, the weekend is looking wet as a series of disturbances aloft and a surface cold front approach the West Coast. Rain will spread across the Pacific Northwest into the Inter-mountain West
tonight through Sunday. The most organized of the precipitation is expected along the Washington and northeast Oregon coasts, as well as along favorable slopes of the northern Rockies. Any snow that falls will
be confined to the highest terrain of the Washington Cascades and the Canadian Rockies.
