Autumn Stats

Here are the numbers for this past autumn's weather (September through November). The temperature averaged 51.7 degrees. This was 0.6 degrees warmer than the long term average (1926 thru 2006), but 0.7 degrees cooler than the short term average (2000 thru 2006). Pretty much a draw.

Autumn precipitation was 9.97", wetter than the long term average of 8.14". The snowfall at our house in west Hood River was 5 inches. An average autumn in Hood River receives 2.3 inches of snow. The historical record for autumn snowfall is 32 inches (1973).

Wind speed averaged 2.3 mph, pretty close to the 2000 thru 2006 average of 2.5 mph.

My previous prediction for this autumn's weather was "warmer and drier". This further establishes my uncanny ability to make inaccurate weather predictions.

You Want Data Points? You Got Data Points.

In the past few days, the WeatherUnderground map on the Hood River Weather site has dramatically increased the number of weather stations displayed, mostly by adding Agrimet, ODOT, and other government weather sites.

This is a major improvement in local weather data. The more data points, the better. And it doesn't bother me in the least that our home weather station data circle is now pretty much totally covered up with other stations' circles. Nope, doesn't bother me a bit. The more the merrier. *sniff*

November Revisited

This November, the average temperature was 0.6 degrees warmer than long term averages, and 0.6 degrees above 2000-2006 averages. Rainfall was slightly above average. The first snow fell on November 18, and additional snow later in the month, for an unofficial total of 5 inches in Hood River. Much higher snow amounts were recorded in the middle and upper valleys. Wind speeds were lower than average, with west and east winds pretty much equally distributed. There was one extended high fog / low clouds inversion event around Thanksgiving.

There were no local records set in November.

	High	Low	Average	Historical Average	Variance
Temperature (F)	66.0	29.0	42.1	41.5	0.6
Wind (mph)	35		1.3	1.8	-0.5
Rainfall (in)	1.17		5.33	4.84	0.49
Barometric (in Hg)	30.56	29.63

Rain

Much less snow overnight than expected, at least for west Hood River. 4 inches on the deck and melting, as the rain starts to pick up. Major flood watch/warnings are posted for most of western Oregon as moisture-laden subtropical fronts blast in today and Monday, with a lot of snow on the ground to melt.

Snow Again

High noon, and the aforementioned snow storm has started at our west Hood River location. Intermittant light flakes so far. 1 inch of previous snow is on our deck, and this storm could add 6 to 12 more. I've received reports of 12 inches of previous snow on the ground in upper Odell, and 17 inches in Parkdale. Add another foot or so on top of that today and tonight, and then rain tomorrow and Monday. Flooding is a distinct possibilty. Hopefully not, as we don't need a repeat of Nature's re-design of the Hood River port area last year by the movement of gazillions of tons of sand and silt from Mt Hood and the Hood River valley down to the Columbia River.

Not that we mere mortals have much of a say over such things.

Feel free to post your snow amounts here.
