The seasonal crossover has occurred, meaning that lower elevations of eastern Washington is now dependably warmer than the western side of the Cascades. During the midwinter, eastern WA is colder than the west side--where the influence of the temperate Pacific Ocean keeps temperatures mild. But as the sun becomes stronger and eastern Washington loses the mid-winter murk of low clouds, east-side folks enjoy a warmer climate. Here is a plot to illustrate, one that shows average monthly temps for Sea-Tac and Richland, WA. Crossover by March and by now now eastern WA has a decided warm edge.
Consider the average max temperatures for the past month, a period that has been colder than normal. The warmest temperatures are clearly over eastern WA and NE Oregon (reds). Tri-cities are particularly toasty.
Here are latest forecasts for the next ten days from the Weather Channel for Seattle and Richland; certainly Richland is far drier and warmer.
Keep going past Ellensburg and the ridge east of town and descend down to Vantage....a very warm, dry spot that is often not in the winds. (If it is in this winds, go north or south to get out of it). Take a hike around Gingko Petrified Wood park...lots of fun.

|View from Cave B Winery. Nice wines and a good restaurant too.|
These are just a few of the excellent day trips that provides gorgeous vistas and warm/dry conditions on most spring days. Of course, check the forecast...there are occasionally periods when these locations experience clouds/precipitation...but they are rare.
