Sierra Fall Weather

When contemplating a late-season Sierra pack trip – say a season concluding mid-October trip – one has to think long and hard about forecasts like this one:

“WARMING TREND CONTINUING THROUGH THURSDAY IN THE HIGH COUNTRY WITH HIGHS NEAR 70 THURSDAY AND FRIDAY….UPPER TROF MOVING IN FRIDAY NIGHT WILL BE ACCOMPANED BY GUSTY WINDS FRIDAY EVENING AND RIDGE TOP GUSTS OF 100MPH AFTER MIDNIGHT….. WX TURNING MUCH COLDER SATURDAY WITH SNOW POSSIBLE IN THE HIGH COUNTRY AND EVEN IN THE TOWN OF MAMMOTH….UPPER PATTERN WILL SPLIT AND SO POSITION OF UPPER CUT OFF TO DETERMAN WHERE BEST PRECIP WILL BE. “”IF”” UPPER CUT OFF DEVELOPS LIKE 12Z NAM (ETA) THEN HIGH COUNTRY COULD GET GOOD SHOT OF SNOWFALL OVER THE WEEKEND…3 TO 6 INCHES POSSIBLE BY MONDAY AM. MAYBE 1 TO 3 IN TOWN…THIS IS JUST A “WAG” SO HANG IN THERE…UPDATE TOMORROW AM. [sic]

While October can be, as I’ve no doubt written here previously, wonderfully sunny and beautiful it can also turn in the opposite direction quite quickly – as it looks like it may do this weekend.

Last October I did a short trip to the Cathedral Lakes/Cathedral Peak area in Yosemite right about this time. (See here and here.) The weather was fine with the exception of a little afternoon snow flurry as we climbed a ridge.

However, friends who visited the area the following weekend encountered nice weather on Saturday, deteriorating weather in the evening followed by an incoming Sierra winter storm which closed most of the Sierra hiways.
