May Summary

Bittinger 2nw Valley and Canaan data put together by Dave Lesher

Overall a warmer than normal May, and wetter than normal. After a cold April we went into May leafless and that carried into mid month, and some areas to week 3 with minimal foliage. Thoughts on that, that limits evapotranspiration and allows for more daytime heating in an already warm pattern. So, a cold April can IMO contribute to an even warmer May due to that. By no means was that a cause of warmth, the overall pattern flipped to a summerlike one after the cold April. Lots of cloudy nights with the wet held temps up overnights. Overall combo of the above led to a very warm May.

 

18Z GFS modeled temps next 10 days. Possibility next week as brief high works in, if it times out correctly, the coldest valleys could run a frost risk.

12Z ECMWF a bit different look on the coming cool.
