Overnight, as N.O.A.A. suggested, the clouds went away, the temperature fell precipitously and the wind died down. That made frost a distinct probability. By the time I went outside any frost that was present had melted, but with sustained temperatures below freezing and no wind I am sure we had frost on the grass. Once the frost/dew has dried I should be able to mow the lawn for the first time this season.
For today N.O.A.A. predicts delightful temperatures, low cloud cover (2%/7%/14%/11%) and no precipitation. There is no way I can embellish that. The Weather Underground model forecast maps and NEXRAD composite radar indicate the same situation.
My Weather Stick points slightly down. The sun is shining directly on it which may be causing a micro-climate with lower than recorded relative humidity. All three of the electronic instruments forecast rising barometric pressure and fair skies. When they all act in concert like that I rarely disagree. I hope they are right, and will also call for fair skies light variable wind and no precipitation.

With the exception of 20:00 hours last evening N.O.A.A. had the temperature forecast very close. For the first half of the overnight they did not have the relative humidity correct, but they got the second half right.
