For those who don't know many years ago I showed off a non scientific analogy using 10 yrs of data (at the time) using Halloween as an indicator of what the coming Winter season would be. For those who missed out on those here is the jest of it.
When Halloween was cooler/wetter than average the following winter was also cooler/wetter than average. The same goes when Halloween was warmer/drier then winter would also be warmer/drier than normal.
The crazy thing about this was it was somewhat in the ballpark of correct. The last several Halloweens have been warm and so have the last several Winters (Dec-Feb) as a season. Even the polar plunge of February 2021 occurred in a winter that was warmer/drier over all. It has been awhile since we've had a cold damp Halloween, and with Tuesday forecast of 50s/30s and following our late October monsoon across NTX, this may be the Winter we have been waiting for, a colder/wetter than average Winter.
Last time we had a cold Halloween was 2019 which was also our official 1st freeze. However winter was a bust overall. Last below average Winters were 2013-2014 (coldest winter since 2009-2010 and the foot of snow that fell that February) and 2014-2015 also saw snow.
Great stuff! I remember your Halloween analogy and was a thing I look forward to. There is some correlation out there probably.
Cycles happen in 30-45 day periods so there might be returns near TG and Christmas too. Anecdotally.
What's more intriguing is that October oscillations can sometimes be precursors for winter since the deck is often started in the month, often due to being a true transition month. -EPO and -NAO set the cards for this current cold episode with strong STJ from the El Nino. Perhaps we will repeat this in winter.
