This Is The Maple Referred To This Morning
We actually had a delightful day, just as N.O.A.A. and I said we would. The temperature actually made it to 60°F. However; the temperature now (22:30 hours) is already down to 36.5°F. If nothing changes in the atmosphere you will hear the crunch of frost underfoot tomorrow morning, and the growing season will be at an end. Because of the angle of the sun I had to take the picture of that maple tree from the other side, but I think you can see how the yellow has taken over.
Someone brought it to my attention that there are a couple things I have not explained recently. If you have already seen this ignore it, since it is for the benefit of newer readers of this report. The strings of temperatures and relative humiditys that show up in the report are from the times the N.W.S. selects as their forecast points During Eastern Daylight Saving Time the daytime forecast points are 08:00/11:00/14:00 and 17:00 hours, and the nighttime forecast points are 20:00/23:00/02:00 and 05:00 hours. When we revert to Standard Time those times will back up one hour. The other explanatory point is that I use N.O.A.A. (National Oceanic and Atmospheric Administration) and N.W.S. (National Weather Service) interchangeably because they are part of the same agency.
Now, on to tonight's forecast. The N.W.S. thinks we will have frost starting around 02:00 hours when the temperature reaches (according to them) 32°F. It is expected to fall from there. Their forecast for the cloud cover is 0%/0%/0%/0%, and that will allow for significant radiational cooling. There is a possibility that we may have some fog at about the same time the temperature is supposed to reach 32°F. If that happens we will dodge another bullet, and if not we will get it right between the tomatoes. There is plenty of ground clutter showing up on the NEXRAD radar, but no showers. The wind has gone calm as well. All these parameters lead me to believe that the time for a killing or black frost is upon us. We will see!
My Weather Stick is smiling, but only very slightly with the 75% relative humidity. All three of the electronic instruments indicate that the barometric pressure is on the rise. Two of them forecast clear skies, while the remote weather station forecasts a mix of clear and cloudy skies (would you believe partly cloudy skies). I think it is going to be cold tonight, and that the time for frost on the pumpkin has arrived. So, get the squash in, let the frost get on the pumpkin and watch for the winter warnings to race across the sky. We may get some more warm weather later in the week, but I think that summer is at an end as of tonight.

The N,W.S. forecast the temperature for all the four forecast points. They missed the morning relative humidity forecast, but correctly forecast the afternoon. Not great, but not bad forecasting either.
