.DISCUSSION...Today through Sunday.

Moisture will continue to wane across the forecast area with mostly
sunny skies expected this afternoon. Following yesterday`s rainfall,
it is possible that water remains across low lying areas across
Lincoln, northeastern Clark, and Mohave counties, so will allow the
Flood Watch to continue until its expiration time at 4 AM PST / 5 AM
MST. Additionally, a Flood Warning remains in effect for the Big
Sandy River from Interstate 40 down to the Mohave / La Paz County
line due to near-record flows as a result of runoff from last
night`s rain. For context, Burro Creek at Highway 93, which flows
into the Big Sandy River, crested at 17.93 feet this afternoon,
breaking the previous record of 17.84 feet measured on February 8th,
1993. As of 2 AM MST, Burro Creek at Highway 93 has subsided to
around 12 feet. Will continue to assess the need for this Flood
Warning through the morning. Cannot rule out patchy fog in low-lying
areas over the next couple of mornings.

A shortwave ridge will set up across the Desert Southwest for the
first half of the work week, followed by zonal-to-northwesterly flow
aloft. Several shortwave troughs will ride along this flow through
the remainder of the work week, which will help to keep temperatures
near-seasonal with afternoon breeziness. On Friday and Saturday, a
shortwave will pinch off of the upper-level flow and will attempt to
close off in the southeastern Pacific Ocean. The resultant north-
south pressure gradients aross the forecast area will combine with
topographic enhancement along the Colorado River Valley to bring
gusty north winds between 25 and 35 mph around Laughlin, Bullhead
City, and Needles Friday and Saturday afternoons. Expect increased
wave heights on Lake Mohave as a result.
