Northern Utah Mountain Weather Forecast

Sunday, April 16, 2006 – 10:30 am

Utah Avalanche Center Weather Home Page

This will be our last mountain weather forecast for the season.  Check our intermittent spring forecasts by going to our home page, above.

Discussion:

Temperatures warming at 10,000’ level today to the mid to upper thirties ahead of the next potent looking storm, expected to arrive tonight.  Southwesterlies to pick up this afternoon to 40-45mph along ridgelines, then drop off behind frontal passage around 2AM.  Temperatures plummet tomorrow into the low teens through late Monday and early Tuesday.  Excellent upper level divergence, pva, instability on all levels should put together a blockbuster.  12-20” are expected through early Tuesday.  Chance that lake-effect may kick in with differential temperatures supporting lake enhancement.  This may provide an additional 10” in the Cottonwoods.

Extended forecast:

Ridge develops behind the exiting trof for mid week.  Temps warm to + 3/+4 by Friday.  Another Low moves down the Pacific coast late in the week.  Looks like it may move northeasterly and kick some moisture our way on southerly flow.  Still seven days out.
