Weather Summary Sunday, Nov. 22
NATIONAL WEATHER SUMMARY:
Across the East, a low pressure system that is currently in the northern Gulf of Mexico is bringing a plethora of moisture into the
Southeast and this will continue over the next 24 hours. Rain will
become less intense tonight as showers creep up the Atlantic
Seaboard toward the New York City area by noon tomorrow. The
heaviest rain is expected to fall across northern Florida, Georgia
and the Carolinas, where half an inch to an inch is expected with
isolated higher amounts. Lighter amounts from 0.20 inch to 0.40
inch are expected across the Tennessee Valley into the southern
Ohio Valley and the Mid Atlantic through tomorrow morning.
Thunderstorms will be mainly confined to the Southeast and a few
may be strong across northern Florida with the threat for gusty
winds. Outside of thunderstorms, winds are on the breezy side but
most gusts should not exceed 25 mph.
The center of the country is enjoying well-above-normal
temperatures with blustery southerly winds today. This is all ahead
of a cold front that is becoming stalled out in the Plains. Ahead
of this front, areas of low clouds, showers and some patchy drizzle
are expected, while scattered and heavier showers will break out
from Nebraska to Minnesota tonight and tomorrow. Rainfall for most
will be under a quarter of an inch with isolated higher amounts
across Nebraska, the eastern Dakotas and western Minnesota. Fair
skies and dry weather will be in place across the southern Plains
through tomorrow morning.
The West has been experiencing a hefty storm system that has already dropped 10 to 20 inches of snow across the Cascades as well as the mountains of the Upper Great Basin. Rain and snow showers will continue to impact this area of the country as well as the central and northern Rockies tonight with additional snowfall
amounts of 1 to 3 inches in the lower elevations and valley floors,
and as much as 4 to 8 additional inches in the Cascades and higher
elevations above 2,000 feet in the Upper Great Basin and northern
Rockies. Rainfall through the lower elevations, mainly west of the
Cascades, will range from 0.10 inch to 0.40 inch with higher
amounts of half an inch to an inch in the favored upslope areas.
Winds have been strong around this storm system and gusts of 30 to
60 mph are expected as this system punches inland today.

ON THIS DATE IN HISTORY:
In 1957, strong Santa Ana winds blew across southern California from Oxnard to San Diego, causing a 28,000-acre brush fire near Crystal Lake. Flying debris and ash forced people off the streets.
In 1992, a major tornado outbreak hit the Tennessee and Ohio Valleys with 45 reported tornadoes during the day. The strongest
