Significant Snow Storm Friday into Saturday

Category: Weather
Mild Start

Today and tomorrow with partly sunny skies and highs in the 50's.

Winds Increase Thursday

We are still focused on the significant winter storm for Friday into Saturday.  The winds will really start to crank up ahead of this storm on Thursday with ridge gusts to 70 mph by afternoon.

Storm Moves In

After midnight Thursday night the first round of precip should begin to move in with snow levels starting around 8000 feet.  We could see 5-8 inches of heavy wet snow on the upper mountain by Friday morning.  

The colder air looks to work in pretty fast with the cold front Friday with snow possibly down to the base by late morning.  The heavy precip may help to pull down the colder air pretty quickly.  We could see 3-5 inches of snow at the base, and 6-10 on the mountain Friday.

Friday night a second push of moisture looks to push in with a 2nd wave.  The latest model runs try to push the snow levels just above the base Friday evening and then falling again by Saturday morning.  That makes the base level forecast tricky.  For now I kept it all snow as the 2nd round of heavy precip may drag down snow levels, but we have to watch closely.  As the colder air works in later Friday night the snow ratios should increase on the mountains.  So we could see 10-16 inches of additional snow on the mountain.  If it stays snow to the base we could see 6-10 inches.

Saturday the snow showers may continue most of the day with cold air in place and highs only in the 20's on the mountains and 30's at the base.  We could see 2-4 inches of snow pile up at the base, and 4-6 inches on the mountain.  The snow showers could linger into Saturday evening before tapering off.

Possible Snow Totals

So this is a 2 day storm with mostly all snow on the mountain above 7000 feet, and we will watch the forecast below that for Friday into Friday night.  Total snowfall on the mountain by Sunday morning could be 2-4 feet.

After the Storm

Cold air stays in place through Monday with highs only in the 30's.  There is a weak system Monday that could brush us with a dusting of snow.  

The rest of next week looks dry but unsettles weather just to our North with the trough in the Eastern Pacific.  The temperatures will warm slightly but should remain cool.

Long-Range

The long-range ensemble runs show that the trough could remain near the West Coast into late April.

The operational model runs do show the possibility of storms for Easter weekend and into the following week.  The storm door looks like it may be open, so we have to see what storms come along.  Overall it may remain active into late April.
