No snow on the pumpkin this year

DENVER — Winter is a no-show this October across the Front Range.  There have been 16 days this month with high temperatures in the 70s and 80s.  Not to mention zero snowfall.  No snow on the pumpkin this time around.

Doesn’t it usually snow on Halloween?  It’s a common perception around town.

Over the past 30 years, records show it only snows on Oct. 31 about once every seven years.  However, if you factor in the Halloweens with snow already on the ground plus snow on Nov. 1, then the statistic jumps all the way up almost 60 percent.

That drives the snowy Halloween perception.

But this Halloween is looking abnormally dry and warm.  There’s no snow in the forecast for Denver. The latest date of first snow on record for Denver occurred on Nov. 21, 1934.

Parks are busy, Front Range 14ers remain busy and it’s been comfortable at Broncos games.

The latest Drought Monitor shows 3.5 percent of Colorado has slipped into a Stage 1 drought.  Take a look at the tan shaded area covering Denver and the Interstate 25 corridor north to Fort Collins:

Why has it been so warm and dry?  The position of the jet stream (storm track) continues to run north of Colorado, preventing snow and colder temperatures from reaching Denver, Boulder and Fort Collins.

Will it change?  Yes, inevitably the jet stream position will change but not until after Nov. 1.
