Atmospheric River Continues
western part of the country has seen quite a bit of moisture since last
week all thanks to a deep plume of tropical moisture originating from
near Hawaii. Note the finger of bright colors stretching from the
Hawaiian Islands to the West Coast.
More Western Precipitation on the Way
According to NOAA's HPC, the 5 day precipitation forecast still suggests a bunch of moisture through the end of the week!
Precipitation Past 7 Days
is unreal... In just a matter of days, we've seen nearly 12" of total
liquid precipitation across parts of northern California.
Update on Folsom Lake
Lake was in the news recently about how low the water level was. How
about this, after a weekend of heavy rainfall, Folsom Lake has risen
nearly 15ft! WOW!
"Folsom Lake has risen about 15 feet in just
four days of rain, and continues to increase as showers linger into
Monday morning. That’s according to preliminary data recorded by sensors
on the lake. The increase may be hard to see with the naked eye, but
puddles around the lake on the western edge, and streams near Browns
Ravine have taken over what has been a dry, barren landscape."

Record Seattle Snow
to my good friend Nicholas Shipes for this picture out of Seattle, WA
where 2.9" of snow fell on Saturday! That was good enough for a daily
snowfall record. The old record was only 0.4" set in 1957.
More Wintry Weather on the Way
a look at all the winter weather headlines that have been issued by the
national weather service across the nation. Note that a few remain in
the western U.S., but there are certainly not as many as there used to
be. Note also the large swath of wintry weather headlines from the Lower
Mississippi Valley to the Mid Atlantic Region. There will be a fairly
significant swath of snow and ice potential through AM Thursday.
Here's the latest from the National Weather Service:
"...A major winter storm will affect the Lower Mississippi Valley and southeastern U.S. through mid-week...
...More heavy rain/snow expected across the Pacific Northwest...
second week of February will be quite active with another round of
wintry precipitation forecast across the southern tier of the country
this week. A frontal boundary sinking southward into the northern Gulf
of Mexico will allow northerly flow to persist along the Gulf Coast.
This will ultimately draw cool Canadian air from the dome of high
pressure to the north which should bring readings to near the freezing
mark. With the sub-freezing air in place, a series of mid-level impulses
will cross overhead resulting in precipitation which should spread from
west to east across the Deep South. What will complicate matters is a
tongue of warmer air just above the surface layer should lead to a
mixture of freezing rain and sleet. This region of mixed wintry
precipitation will focus along the rain/snow line with fairly extensive
ice accumulations being forecast by the WPC winter weather desk. Through
Wednesday evening, the current forecast depicts anywhere from 2 to 6
inches of snow from northern Mississippi eastward into much of North
Carolina. A localized heavier axis is possible along upslope regions of
the Southern Appalachians. Additionally, bounding this area of snow to
the south will be sufficiently high ice accumulations extending from
northern Louisiana through central portions of the southern states into
the southeastern U.S. coast. The current maxima is expected from eastern
Georgia into central South Carolina with 0.50 to 0.75 inches of ice
possible. Of course any measurable ice will make travel hazardous."
Empty Store Shelves in Georgia
about this... I guess people are taking this store seriously. The store
shelves are nearly empty in Smyrna, GA. Thanks to Steve Schmidt for the
FutureRadar Through PM Wednesday
the outlook through PM Wednesday, which shows a fairly robust blob of
moisture across the Gulf Coast States through that time period. This
southern branch of precipitation is going to fall in a wintry fashion.
Unfortunately, there's a pretty good snow and freezing rain potential.
Southern Snow Potential
amounts could ramp up quickly with this particular system as it nears
the Carolinas. The particular image below suggests 3" to 6"+ possible in
some areas from Georgia to North Carolina by Wednesday evening.
Here's NOAA's probability of 0.25" or more through Thursday. Note the near 80% chance across parts of the Carolinas.
Ice Storm Warning
National Weather Service out of Charleston, SC has issued an Ice Storm
Warning for parts of South Carolina from PM Tuesday into AM Thursday.
STORM WARNING IN EFFECT FROM MIDNIGHT TUESDAY NIGHT TO 10 AM EST
THURSDAY... THE NATIONAL WEATHER SERVICE IN CHARLESTON HAS ISSUED AN ICE
STORM WARNING...WHICH IS IN EFFECT FROM MIDNIGHT TUESDAY NIGHT TO 10 AM
* ICE ACCUMULATIONS...AROUND ONE QUARTER OF AN INCH.
TIMING...RAIN IS FORECAST TO MIX OR CHANGE TO FREEZING RAIN TUESDAY
EVENING INTO THE OVERNIGHT HOURS...THEN CONTINUE INTO AS LATE AS
* IMPACTS...SIGNIFICANT ICE ACCUMULATIONS COULD
CREATE DANGEROUS OR IMPOSSIBLE DRIVING CONDITIONS...ESPECIALLY ON
BRIDGES...OVERPASSES AND UNTREATED ROADS. DAMAGE TO TREES AND POWER
LINES ARE LIKELY AS WELL AS POWER OUTAGES ACROSS THE AREA.
Watching the Low Track Northeast
is going to be an interesting storm system to watch develop. Not only
will it have significant impacts on places in the south, but there may
also be some issues later this week in the Northeast as the storm
intensifies... The storm track could bring accumulating snow to the
coastal communities in the Northeast as it skirts along the coast. Stay
Warmer Weather Ahead
a graphic that a few folks might be appreciative of... NOAA's Climate
Prediction Center suggests that the 6 to 10 day temperature outlook
looks much warmer than what we've currently been dealing with! Note also
how Alaska will be cooling down during this time frame.
Thanks for checking in and have a great rest of your week!
