It did take a while to warm up today after the cloudy start. About mid-afternoon the clouds were completely gone, and it turned into an absolutely gorgeous afternoon. If you could choose this would apparently be the week for a vacation. The green on the deciduous trees is becoming muted, and the fall foliage colors are starting to come into their own. It does seem a bit early, but I think I say that every year around this time. N.O.A.A. did call for a day without precipitation, and they were correct. I think their cloud cover estimates were a bit low for the early part of the day, but I cannot give a real accurate estimate of that parameter. My estimates tend to be a bit subjective and based only on what I can see.
For the overnight the N.W.S. is again forecasting no precipitation with some cloud cover (6%/16%25%/13%). The fact that the cloud cover will be as low as it well may allow for considerable radiational cooling. There are no storms on the NEXRAD regional radar, and the Weather Underground model forecast maps indicate clear weather at least through tomorrow.
My Weather Stick is smiling at the 64% relative humidity, and so am I. There has been some wind today, but it has dropped off to nothing. All three of my electronic instruments are calling for fluctuating sky conditions with rising barometric pressure. When I stepped outside to look at the Weather Stick and observe the sky conditions I could not see a cloud. All I could see were millions of stars and the Milky Way galaxy. It is absolutely incredible how many stars we can see on a clear night like this. It never ceases to amaze me. If you live in an area that is prone to early frost, and you have tender vegetation this would be the night to protect it. I know I keep saying it, but it just seems that this is too early to be talking about frost. At the end of the month I would not be surprised to be talking about frost, but this is not even the end of the first week in September, and there are some places that have already had some light frost. I will think it, but I will not make my usual comment (where is Al Gore now? This frost is inconvenient!) My forecast is for a cool night with lots of stars and very little wind. If the wind does pick up we may not get the frost. Tomorrow morning will tell the tale.

The N.W.S had the forecast temperature within five degrees of the actual temperature in Wilton, Maine for three of the four forecast periods overnight. They missed the 11:00 hour point by much more than 5 degrees. I suspect the cloud cover had an effect on the temperature, and for that reason they missed that point. They missed the relative humidity points in the middle of the day, and the effect of less sun probably had something to do with those errors. Oh well, they will try again tomorrow.
