High Knob Massif
Color Peaking In Upper Elevations
Beautiful color is also developing in Flag Rock Recreation Area, and gradually spreading down the northern slopes to the City of Norton and the U.S. 23 corridor (Country Music Highway).

An array of gorgeous color is developing across upper elevations in the High Knob Massif, above 3000 feet, where this weekend through next week and weekend is expected to offer the best color.
An acceleration of color changes is also expected at lower
to middle elevations as frost and sub-freezing conditions develop during upcoming nights.
The potential exists for a grand climax to occur by next weekend with a large vertical elevation range in various stages of peak conditions (*).

(below 3000 feet).

What day will the climax be is always in the eye of the beholder, but some trees are already becoming bare at highest elevations such that now is the time to enjoy color in upper elevations.

as of October 5, especially in high valleys near and upstream of Big Cherry Lake and within settings where cooling nocturnal air drains along slopes into basins and upper portions of gorges (*).
*Numerous nights near and below freezing have occurred in Big Cherry Lake basin which helped trigger significant mid-late September to early October color changes.

Autumn 2022 has to date been significantly cooler and drier than average, and this trend is currently expected to continue into at least mid-October when the potential exists for an unseasonably cold period to develop.

(M): Some missing moisture in undercatch and frozen precipitation, with corrections applied for the 24.4 meter (80 feet) tall dam structure where rain gauges are located. Corrections are based upon 86-months of direct comparisons between NWS and IFLOWS at Big Cherry Dam (including occasional snow core-water content data).
Water levels in the City of Norton dual reservoir system have been dropping with daily withdrawal being greater than recharge during recent weeks.

Northern hardwoods intermixed in general
mixed-mesophytic forests generate a truly rich color palette. This adds greatly to the majesty
of this special season in the High Knob Massif.
Both of these forest types (Northern Hardwoods and Mixed-mesophytic) are of global significance.

wanes in many trees before they fully begin to display their "true" colors as photosynthetic carbon fixation is being shut-down. This allows one with experience, at least, to see how many trees will be quickly developing color in coming days.

With calm winds prior to sunset the lake surface became like a fine glass, very reflective. This was in contrast to winds so strong at the summit-level that the High Knob Aid Station tents had to be secured from blowing down.

Many maple trees had already lost leaves around the lake, but it remained beautiful with trees along the drive into the lake basin being at peak color to contrast again with past peak conditions at higher elevations in the massif.
This made for a chilly evening and night, but increasing clouds checked the temperature drop and kept it significantly milder than it would
have been under clear skies.

As of Monday (17 October) forecast models were suggesting that the first snow showers and flurries would fall on Tuesday. Not abnormal for here (at least above 3000 feet).

The first snow and riming of the 2022-23 Winter Season was observed in the High Knob Massif during 18 October, with sleet pellets down to
at least 1560 feet in Clintwood.

Just image if this had struck 2-3 days earlier runners of the Cloudsplitter race, all aids and EMS personnel, would have had to endure temperatures in the low-mid 20s with wind chills of 0 to 10 degrees (F) in gusts along the crest.

My friend Wally Smith posted a beautiful photograph on his Twitter feed, with remarks about conditions he experienced while on the mountain. Note color remains pretty but is
well past peak at these upper elevations.

High Mountain Basin Update
Before looking at September-October, I want
to briefly recap Summer 2022 where the mean temperature on the floor of Big Cherry Lake
basin ended up being 64.8 degrees.
Summer nights cooled to a temperature
of 53.6 degrees on average (*).
*A summer mean of 66.9 degrees was observed in
Burkes Garden where nights cooled to 55.9 degrees
on average.
Big Cherry Lake Basin
Meteorological Summer
The Great Valley is used for comparison, with a mean summer temperature of 75.8 degrees in the Tri-Cities and nights that cooled to 64.5 degrees
on average (11.0 degrees milder than Big Cherry).

Early-Mid Autumn 2022
Moving forward, autumn arrived in earnest during mid-late September with the first frost and freeze in Big Cherry where the temperature dipped to
27.9 degrees at this observation site (**).
Big Cherry Lake Basin
01 September to 28 October 2022
**A colder location in the basin that can get 1-2 degrees colder on good radiational nights did not have a sensor recording during this time period. This implied that lowest temperatures could have been around 26-27 degrees in September and 16-17 degrees in October.
There was a large vertical temperature
spread in the basin, especially at night,
throughout early-mid Autumn.
01 September to 28 October
Vertical Temp Differences and Decoupling
Nocturnal inversion formation forced the basin floor to become decoupled and different from the overlying atmosphere during 58.8% of total
time during September.
Big Cherry Lake Basin
Decoupled Time on Basin Floor
The low temperature near 3450 feet elevation along the mid-slope above the basin floor dipped to only 38.0 degrees, more than 10 degrees warmer than coldest sites in the wetland valleys.
Big Cherry Lake Basin
Month of September 2022
Using the Tri-Cities again as a comparison, the mean September temperature was 67.5 degrees
and the average night-time low was 55.6 degrees. These readings were 11 to 12 degrees milder than the Big Cherry wetland valleys.

Month of September 2022
Mean 10 to 12 degree differences are huge
when applying to daily average temperatures.

Best cooling nights generated 20-30 degree vertical temperature differences within the basin between colder floors and milder mid-slopes and rims.
