The
Snapshot: Scattered
rain showers today changing to moderate snow tonight. Windy tonight with lowering temperatures, snow
ending tomorrow.
The
Science: A prefrontal wave has pushed rain into the mountains
this morning. The approaching cold fronts (yes there are two) will increase precipitation
this afternoon. Rain is expected to turn
to snow with the passing of the first front tonight. Moderate snow is expected through the night. High pressure develops behind the second cold
front which will cut off the precipitation tomorrow.
4-7day
Long Range: The
weekend will be dry, chilly and mostly sunny under strengthening high
pressure. Long range models show a
pattern change to NW flow developing next week.
Watch for storms tracking through the region during the second part of
the week.
