A blocking pattern is forecasted by both the GFS and ECMWF. 5 Day 500mb means show upper Trof over the Great Basin while the daily’s keep Vort centers moving counter clock wise around upper low with NE flow into the Sierra. Showers and possible thunderstorms will most likely be diurnally driven with some nocturnal action at times.

 

Expect the chance of showers each day this week, along with cooler than normal temps. The weekend outlook still keeps the chance of showers, however temperatures return to near normal for this time of the year. (Low 60s) The snow level will remain high, between 9000 and 10,000 feet for the most part. There may be periods of grapple with the daytime convection.

Temperatures in the high country are likely to be below normal over the next 5 days

Daytime highs will be in the low to mid 50s while the lows in the 30s…

The Freezing Level is expected to rise over the weekend and so highs will approach 60 by Saturday.

 

Longer Range:

Long Range forecasting is dicing at best this time of the year…..Even two weeks out.  However, for those that want me to take a shot at it, the Memorial Day holiday weekend looks fair, with warmer than normal temperatures.
