Late yesterday (9/13/25) shower amounts via CoCoRaHs Click if in disbelief. 

It got quite threatening looking up here in the afternoon and evening yesterday.  Nothing, not even a drip.  Everything was well east.

Cold early September is a classic fake out. We don't truly shake summer off totally these days until like mid October.

Despite the dry end to August, precipitation is running above normal in parts of the region through the first two weeks of September and much above the amount for last year in all areas. 2025 is September 1-13 precipitation, but none is expected today. While this does not ensure that the month will finish above normal, it is a welcome development.

With no cool downs in sight September might average seasonable if not slightly above normal no? Much warmer looking nights ahead as well.

There's hints of a cool down for next weekend plus any coastal influence will keep highs down. 

No definitive fall like cool down yet though

Hi Don-

Can you do the same chart for Y.T.D. and 12 month rolling?  If not too much trouble.  I'd love to see what that looks like.

Thanks-

Mike

Thanks Don.  That's kind of what I was expecting it to look like.  My perception was that it has been a drier than normal year to date and drier than 2024 and a much drier 12 month period compared to normal and 2024.  It has just been dry.  Barring any tropical activity for the second half of this month September I think will finish drier than normal.  Not going to be much rainfall over this sub forum for the coming week.
