2008 BLOSSOM DEGREES, WENATCHEE finished LAST YEAR NORMAL

Totals computed from Feb. 1, on a base of 43 deg., and NOT adjusted for green tip.

...This is the final Morning forecast
for the 2008 spring frost season...

The last forecast of the season will be issued this evening.

DISCUSSION:  Some wind held temperatures up in the 40s last night, but isolated locations registered temperatures in the upper 30s.

Southerly air flow aloft is bringing clouds northward from California this morning.  This will lead to some showers developing over the mountains later today and spreading into the valleys this evening or tonight.  An isolated thunderstorm is possible as well.   Temperatures tonight should be much warmer as a result.

The upper level weather system offshore will move inland on Sunday and move east of us by Monday morning.  Showers may continue Sunday in the Okanogan and the Cascades then dry weather is expected through Monday.  Another weather system will move in rapidly on Monday night bringing some light rain to the valleys on Tuesday.  The further outlook indicates a continuation of rapidly moving weather systems from the Pacific moving inland through the remainder of the coming week.  Not much rain is seen from most of these, but cool temperatures will continue even beyond next weekend.  The air mass will continue to be cool enough at night for some readings in the upper 30s  in colder spots when wind and clouds are absent.
