,,, This is the Final Clearwest frost forecast
for the 2008 frost season...

Discussion:   Clouds are moving northward through Washington this evening accompanying an upper level disturbance ahead of an offshore weather system.  Scattered showers and possibly a thunderstorm will occur followed by some late night clearing.

The offshore weather system will move inland on Sunday and east of us on Monday.  Colder air will accompany this system which will settle in over eastern Washington for much of the coming week..  A west to northwest flow of cool Pacific air will reinforce this air mass on a couple occasions during the next 4 or 5 days.  The most likely periods for rainfall is  tonight and Sunday and again on Tuesday.  Cloudy periods and frequent wind will limit nighttime temperature fall, but on nights that have a minimum of wind or clouds, there will be a potential for temperatures in the low to mid 30s.  No significant warming is seen before late next weekend.

The 5 pm temperature at Omak area was 80 with a dewpoint of 37.  
The 5 pm temperature at Wenatchee was 81 with a dewpoint of 35.
