Time and Day: 0700 Tuesday
The Snapshot:
Mild temperatures with light mixed rain
and snow today. The rain vs snow game
will continue through at least Wednesday. Cooler temperatures and snow will bring
us through the weekend.
The Science
Current Observations: 6 am - It started raining around midnight last night with .19” of water thus
far. It is now snowing with no new snow
being reported. The temperature has dropped
a few degrees to 31. The barometer is
holding steady at 1017mb’s, and the winds have shifted to SW and are fairly light.
The Forecast: The
ridge of high pressure that was responsible for the dry patch of weather shifted
east last night. This opened the door for moist SW flow to move in. Unstable southwest flow will keep mild
temperatures and light precipitation falling in the mountains today and most of
tomorrow. A warm front lifts up through
the region tomorrow evening for another shot of mixed rain and snow.
The Long Range: A very active weather pattern with several
frontal systems is preparing to impact the PNW heading into the weekend. All this has cooler NW flow associated with
it – so, prepare for a very snowy
weekend.
