MOUNTAIN WEATHER FORECAST

Time and Day: 0700 Friday

The Snapshot:   Partly sunny with passing snow showers today.  The weekend is beginning to look pretty good with dry and warmer weather developing.

The Science: This morning's satellite imagery has spotty showers and partly cloudy skies over the region.  The atmosphere will remain unstable under weak westerly flow with slowly rising pressure gradients taking shape late tonight. Dry and warmer weather is expected to begin tomorrow as the pressure continues to rise and the atmosphere stabilizes.

The Long Range:  Next week will start out dry and warm with light rain expected on Tuesday.  There are early signs in the long range weather models of a trend to drier, typical PNW spring weather.  It's about time.
