SPOT WEATHER FORECAST

12/25/2009 Weather

Short term: High pressure aloft with cool air trapped in the eastern basin has created this strong inversion layer. The sun will make a good go at trying to burn off the lower level clouds, but it may not be able to. Inversion conditions will continue for the next few days.

Long-term: This dry weather pattern will continue through the weekend as the approaching systems split and go around us. There is some promise next week as the Northern Jet Stream tries to break down the split flow. This will be our next chance for snow – hopefully to bring in the New Year. Happy Holidays.

Temps will remain quite cool below the inversion layer. The surface temperature will depend on what elevation you are standing at, could be a 20+ degree difference.

Winds: Strong east/west temperature gradients will push east winds through the Pass today and tomorrow. It will be possible to get east wind gust in the 20’s
