Take a look at the National Weather Service outlook for Coulee City, WA for updated weather reports.  I just checked, temps in the 70's to low 80's with no wind or severe storms predicted past this evening.

As a side note, based on my fishing logs over the past two and a half years, I have determined that the NWS provides me with the most accurate weather reports prior to my trips.  I have over ten years of detailed bass fishing logs that include actual weather as well as predicted by the internet reporting sites.  With the advent of internet based weather reporting, I began using Accuweather as my report of choice a couple of years ago.  Based on the actual data that I logged in after my trips, I did some research and found that NWS was more accurate by an astounding 50% over other internet weather sites including Accuweather.  This is improtant stuff if we are serious about catching fish on our trips.  I especially like the weather spotters that report to the NWS site.  Just some food for thought.
