Our freakish late November “heat wave” has ended. After spending 4 days above our NORMAL HIGH TEMPERATURE (49-50), we just dropped to 48 degrees as a cold front moved overhead and the wind switched around to gusty northwesterly instead of the constant/warm south wind.
Let’s recap the 5 warm temperature records tied or broken at PDX:
TUESDAY: Tied record high temp (63), new record warm low temp (54)
WEDNESDAY: New record high temp (62), new record warm low temp (54)
THURSDAY: New record warm low temp (54)
This has totally decimated what little Cascade snowpack we had. Both Timberline and Meadows went from about a 2 foot base to just patches of snow on the ground with lots of bare spots. The official SNOTEL sensor at 5400′ just below Timberline went from 19″ to 4″ depth. During that time 4.80″ of rain fell.
Good news though! Looks like up to a foot could fall in the next 18 hours. Here’s the plan:
If you are traveling the next 2 days, this means bad news in the mountains…
I’ll blog later (after evening models come in) about the possibility for lower elevation snow and/or freezing rain.
