Time and Day: 0630 Friday
The Snapshot:
Moderate snow showers are on the docket
for the weekend and likely beyond. It seems that our little January thaw is over and
a return to our regularly scheduled winter is on.
The Science
Current Observations: 3” of new snow fell overnight. The temperature profile is 28 in the base and
24 on the upper mountain. The barometer
is holding steady at 1007mb’s. The winds are light and out of the west. This
morning’s radar has plenty of showers
heading toward the mountains.
The Forecast: A cool, unstable, moist airmass rotating
around an offshore low-pressure cell will
spin bands of light to moderate snow showers into the mountains for the next
several days. There are complex embedded fronts hidden in this pattern
which could enhance precipitation at times. Freezing levels will be in favor
snow through the weekend.
The Long Range: The northern jet stream has finally decided
to shift more northerly. This is
allowing colder NW air to mix well with multiple storms developing. Therefore, we can expect this active weather
pattern to continue through the weekend and likely well into next week.
