...Snow is expected to overspread the northern and central Rockies as well
as the High Plains behind a strong cold front during the next couple of
days...
...Heavy showers and thunderstorms continue across northern/central
Florida...
As the remaining light snow slowly tapers off over the southern Rockies, a
surge of cold air from Canada is entering Montana early this morning. The
cold surge will bring rapidly falling temperatures as well as a quick
burst of snow down across the northern Rockies to the High Plains today
and into Monday, followed by the central Rockies and central High Plains
by Monday evening. The highest snowfall amounts are forecast to occur
along the Bighorn Mountains of north-central Wyoming, where over a foot of
snow is possible. Other mountain peaks from northwest Montana to Wyoming,
as well as the Black Hills of Wyoming and South Dakota, could see snowfall
accumulations over 6 inches. Winter Storm Watches and Winter Weather
Advisories have been issued. Light snow could extend as far east as the
Upper Midwest as a low pressure wave develops along the front and moves
across the region.
Meanwhile, active weather is expected to linger across northern to central
Florida where a front will become nearly stationary. Occasional showers
heavy at times together with embedded thunderstorms can be expected to
continue through Monday. A few storms could turn severe. In addition,
flash flooding will be a concern due to upwards of 5 inches of rain
forecast to fall across northern/central Florida during the next few days.
A Marginal Risk of Excessive Rainfall has been issued to highlight the
potential hazard.
Much of the lower 48 will experience below average temperatures over the
next few days. The only exceptions will be found across southern Florida,
New England, and along the West Coast where above normal temperatures
remain locked in place. Finally, residents in parts of the interior
western U.S. as well as southern California should beware of an elevated
risk of wildfire during the next couple of days.
