...Flooding chances continue to increase for next week...
A wet pattern will set up across the Tennessee Valley for much of the
next week, with several rounds of heavy rainfall affecting Northern
Alabama and portions of Southern Middle Tennessee beginning late
Monday. Throughout the week ahead, a frontal boundary will stall
across the area, though there is some uncertainty as to exactly where
this feature will end up. The heaviest rainfall axis is expected to
be along this stalled frontal boundary, where anywhere between 5 to 8
inches of rainfall are forecast. Isolated higher amounts are
possible.
While rainfall is literally forecasted for every day next week, the
greatest potential for heavy rainfall and flooding will be from
late Monday evening through at least midday Wednesday, if not
lingering into Thursday. Given the wet ground conditions in place
from recent rainfall, much of this expected 4-9" of rainfall will
immediately convert to runoff. This will overwhelm the natural
drainage processes, leading to flash flooding potentially at the
onset of the heavy rain, and later in the week, widespread river
flooding. Again, while there is still some uncertainty in exactly
where the front will stall, nearly all of the river gages on the
Tennessee River (and those on tributaries that feed into the
Tennessee River) will likely reach flood stage at some point next
week. The question will be how many will reach Moderate Stage (or
higher). Lingering flooding on the Tennessee River will begin late
next week, and will likely linger into the following week as well.
Residents across Northern Alabama and Southern Middle Tennessee
should continue to monitor this unfolding weather situation over the
holiday weekend and stay tuned to further forecast updates from NWS
Huntsville!
