AgWeatherNet Weekly Weather Outlook for July 22 to July 28, 2017

Dry and Warmer than Normal Weather Continues

It should hardly come as shocking news that dry and very warm weather is likely in the coming days. However, as has been the case so far this summer, there are still plenty of regional subtleties to discuss in terms of day to day temperature variation. Hot conditions on Saturday will generally give way to even hotter weather on Sunday and into early next week. Thankfully, cooling temperatures are expected for the middle to latter part of next week, before leveling off or climbing again at the end of the period. Days should initially be toasty even in interior western areas, but the coast is anticipated to continue its pleasant trend of avoiding the heat.

Given that we are entering late July, it is an appropriate time to assess our climatological status. In terms of standard surface air temperatures (6 feet above the ground), central Washington is entering what is typically the warmest time of the year (late July/early August). By contrast, places like the coast and the mountains have to wait until August to reach their average temperature zenith. Since the ocean and the upper atmosphere heat up and cool down rather slowly, heat lag allows for delayed annual maximum temperatures. In any case, with the summer solstice a month behind us, the decreasing solar radiation will eventually catch up with the climate system. In the meantime, the potential for hot weather will linger well into August.
