Time and Day: 0700 Thursday
The Snapshot:
Seasonally cool with moderate to heavy snow showers and gusty ridge top winds
today. A bit warmer with heavy mixed
rain and snow can be anticipated tomorrow.
This pattern will likely continue through the weekend.
The Science
Current Observations:
.28” of water produce 2” of
snow overnight. The temperature profile is 29 base - 24
ridges. The westerly winds kicked in
around midnight last night and are currently gusting into the 30’s. The
barometer is still in the low pressure range at 1009mb’s. This morning radar has broken but abundant
snow showers moving through the mountains and more activity heading in from the
west.
The Forecast: There is plentiful moisture on the way driven by
unstable WSW flow. The freezing levels
will remain below 4000’ but seasonal daytime warming will likely push surface
temperature to 320f.
As we move toward the
weekend, the snow levels, in relation to freezing levels, will be the
determining factor on how much snow will accumulate. This is proving to be hard to nail down, so
for now, expect as much as a foot of new snow by Saturday morning.
The Long Range: The mixed rain and snow game continues
through the weekend.
24hr values daily 4am to 4am.
