Time and Day: 0630 Wednesday
The Snapshot: Light snow showers today, periods of rain and snow will
continue through the weekend.
The Science: The main front is well past the mountains and heading
east. Last night’s system produced around
4” of snow, with another inch possible with the left over instability. The next front will arrive late tonight with
snow changing to mixed rain and snow and eventually light rain tomorrow below
4500’.
Strong southerly flow associated with tonight warm front, will erode the
cold air trapped in the eastern basin (no more east flow). This will raise
freezing level to +-5000’ tomorrow. A
cold front will then follow with moderate snow showers and strong westerly flow. Storm totals to come later today.
Long
Range: The games start all over on
Saturday with east flow snow changing to mixed rain and snow. The
storms keep rolling in with freezing levels bouncing between 4000’ and 5000’
through the middle of next week.
