…Heavy Snowfall for parts of the Sierra Nevada…
…Above average temperatures spread from the central U.S. into the East
while cold airmass descends into the Great Plains…
A weak low pressure system will continue directing a plume of moisture at
the West Coast over the next few days. This will likely result in coastal
and low elevation rain, while moderate to heavy snow proliferates across
the coastal ranges of Washington, Oregon and California. The heaviest
snowfall is likely to occur over portions of the Sierra Nevada, with the
southern Sierra poised to accumulate 2-3 feet with isolated higher
amounts. Snow showers will also impact the Colorado Rockies over the next
few days. Heavy rain and snow chances increase on Tuesday as another
atmospheric river event arrives across parts of central California.
Relatively zonal flow across the southern tier of the country will support
another day of above average temperatures for the Central/Southern U.S.
today. An upper trough will pickup steam over the northern tier and send a
strong cold front diving south through the Great Plains over the next 48
hours. Highs in the teens will represent 20-30 degree departures from
normal over the Northern High Plains through Monday. Temperatures will
drop precipitously, from highs in 60s and 70s today to 40s and 50s on
Monday over parts of the Southern Plains as the cold front propagates
through. The associated warm front will spread mild air across the Eastern
U.S. on Monday before the cold front arrives and drops temperatures for
the rest of the week.
