Discussion
“Major” Hurricane Ida slammed into Louisiana on Sunday as a category 4 storm and the remnants will move slowly to the north today and then to the northeast over the next couple of days. A stalling frontal system will generate scattered showers and thunderstorms later today and tonight in the Mid-Atlantic region and then will act as a pathway for Ida’s tremendous levels of moisture to push in here at mid-week. Significant rainfall will push into the Tennessee Valley over the next 24 hours and then reach the Mid-Atlantic region and Northeast US from later Wednesday to early Thursday. Rainfall amounts of up to several inches is possible in the Mid-Atlantic region and given the already well saturated grounds, flash flooding is a strong likelihood in many areas. Cooler, drier air pushes in for the late week on the heels of the mid-week tropical rainfall event with highs generally confined to the 70’s.
