MOUNTAIN WEATHER FORECAST

Time and Day: 0700 Tuesday

The Snapshot:  Passing snow showers with warmer temperatures can be expected today.   Drying begins tomorrow and will last through the upcoming weekend.  Yes, the long range outlook has changed.  

The Science:  A low-pressure system, stalled off of the Oregon coast, will continue to spin band of moisture up through the Cascade Mountain Range today and tomorrow.   Models have this low-pressure cell tracking south into the California waters during the next 24-48hrs; this will allow high pressure to build over the NW creating a split flow pattern.  Therefore, expect the rest of the week to be mostly dry with partial clearing.   

Long Range:  The upcoming weekend is shaping up to be dry and cold under building high pressure.  This split flow pattern will likely last into the start of the new week.
