The weather balloon released at Salem this morning found record warm temperatures overhead. Yes, they still actually fill a balloon and track its movements twice a day. When it reached the 850 millibar level (about 5,000′), the temperature was 21.8 degrees Celsius! That’s 71 degrees F.
So what’s the big deal? Well that’s one of the mandatory levels, one we frequently refer to in meteorology. You can look at past climatology on the SPC website and see that it was the warmest temperature ever recorded at that elevation over Salem in the 2nd half of October. This morning’s temp is the big circle. The average for any date is the yellow line. Or orange, or whatever it is…I’m a bit color blind.
Note there is one day it hit the same temperature the 1st of November in the past. But this is the latest we’ve seen such a warm temp otherwise. This nifty sounding tool from Jim Little’s website shows it was above 70 from around 2,800′ to 5,000′ this morning! The blue line is the 4-5am sounding.
That’s an incredibly warm atmosphere for mid October. IF we had solid sunshine today I think we’d have an 80+ day coming up. But I think with the cloud cover and a bit weaker easterly wind we’ll stay below 80. Or maybe I’m getting old and conservative.
Yesterday Vancouver broke a record (81) and Portland tied (80)
That’s it, have to plant my cover crop in the garden and ride the bike on the last day it’ll be 70 by noon. Enjoy your Friday!
