After dry summer months to have the driest September raises concerns over wells, however the first half of October and the current forecast looks like the corner was turned.

     On average humidity this was the first September under 70%.  The below chart is the average humidity for all the Septembers in my records.  Not labeling the years. Chart starts in 1998.


















     Our chickens have loved the long dry period.

They have made several dirt bath spots scattered

around the yard.


Yearly Temperature Rankings


     On the average temperature through the end of

September, I have not checked on this.  The monthly

moves show this is a warmer year so far, but three

months left can flip it back to being near normal.

However not sure I want a colder Fall and start to

Winter.


NOAA Graphic for Climate Behaviors in La Nina

posted below. In the climate forecast from Nov-Feb

NOAA shows the Northeast as slightly above average

for temperatures and equal chance for above or below on the precipitation.



















The above graphic shows what has been observed in previous La Nina events.  Current readings show this is a strengthening event.
