Multiple Hazards for the Southwestern U.S.
Improving wind and fire weather conditions for California. Heavy rains and possible flash flooding across portions of the Desert Southwest. Heavy rains developing across the Lower Mississippi Valley/Central Gulf Coast on Thursday. Lake effect snows diminish Wednesday but return on Thursday.
Forecast for Wednesday, January 20, 2021
Relief is in sight for California which has experienced damaging winds and
critical fire weather conditions. The combination of the strong area of
high pressure over the Great Basin and a strong low off the Southern
California coast which have been responsible for the very windy conditions
will be weakening on Wednesday. Strong winds and a fire weather threat
will continue through Wednesday morning, with improving conditions by
Wednesday night.
As the area of low pressure off the Southern California coast pushes
eastward into the northern Baja peninsula, the chance of heavy rains will
be increasing to its northeast over portions of the Desert Southwest from
southeast California into southern Arizona. These heavy rains may produce
localized flash flooding with these areas under flash flood watches.
While the low moving into the northern Baja Peninsula produces rains over
portions of the Desert Southwest, it will also be responsible for pushing
abundant moisture eastward into the Southern Plains on Wednesday and into
the Lower Mississippi Valley/Central Gulf Coast region on Thursday. Light
to moderate precipitation totals expected across the Southern Plains on
Wednesday into early Thursday, while heavier totals developing across the
Lower Mississippi Valley/Central Gulf Coastal region during Thursday into
early Friday.
Heavy lake effect snows downwind of Lakes Erie and Ontario are expected to
diminish on Wednesday. However, the active lake effect snow pattern will
return again on Thursday as favorable westerly to northwesterly flow
develops across all of the Great Lakes in the wake of a fast moving cold
front sweeping through the Great Lakes. This active lake effect pattern
will continue into Friday with locally heavy snows downwind of all of the
Great Lakes.
