In 73 yrs of records at Sea-Tac there has only been 8 days w/highs 43° or less in the 1st week of Nov, 3 of them in the last 3 days. #wawx

Todays Weatherbell Daily Update www.weatherbell.com/Cold prediction for December in eastern US. While he doesn't mention Europe, the cold blob shown over western Europe in the same image looks amazing. I was browsing through previously run CET data for analog years and came across this, which I don't remember posting. So for those of you that track extreme days in central England - Winter and Summer - here you go. LOOK AT SUMMER 1807 TO 1907.

Are the high pressures in an odd place?? The major highs at 500mb appear concentrated between 10 and 20 N - Mexico, central Africa and eastward. Further south than normal? Does that say anything about the Hadley cells? If so, how would you measure it?

Historical (decadal) trends in seasonal NAO and station pressure patterns are in the charts below. The NAO is just the normalized deviation of a southern station minus the same for iceland. Note that your run of higher number of summer days < 10th percentile (1810-1907) might have something to do with the Azores-to-Iceland pressure gradient being negative during the later part of that period. Note that the present seems to be repeating that pattern.

Asgard I've always loved the name Snorri Sturluson. Icy cold Ring to it.

Toward the end of the chapter Snorri becomes prophetic, describing Ragnarök, the twilight of the gods. Much of it sounds like the Apocalypse, by which Snorri, a Christian, can hardly fail to have been influenced.[original research?][neutrality is disputed] It will begin with three winters of snow, with no summers in between. Wars will follow, then earthquakes and tidal waves. The sky will split open and out will ride the sons of Muspell intent on universal destruction. They will try to enter heaven but Bifröst will break (Section 55). Heimdall will blow his mighty horn Gjöll and the Æsir and Einherjar will ride out to battle. Most of the Æsir will die and Asgard be destroyed. Snorri quotes his own source saying: "The sun will go black, earth sink in the sea, heaven be stripped of its bright stars;...." (Section 56). Afterwards, the earth rises again from the sea, is fairer than before, and where Asgard used to be a remnant of the Æsir gather, some coming up from Hel, and talk and play chess all day with the golden chessmen of the ancient Æsir, which they find in the grass (Section 58). (Wikipedia) Fire will become ice ... and Mann will ascend to Valhalla.

Too much coffee probably. I meant the snow. We may have had a light dusting overnight but it had all melted by the time I got up.

Record cold last weekend gave way to record warmth this weekend for my part of the world. The fall/winter 2017 has seen it's share of extremes in both directions.
Living on the Gulf Coast we have become accustomed to rapid changes in the weather. Cold shots from the Northern Plains can change the weather on a dime and when the winds turn back to the south the warmth comes with it. Most times in short order.
But this type of weather is really indicative of a loopy jet. Keep in mind it is November now and highs in the upper 80's are rare even for us. From spacecityweather.com:
Houston experienced some very warm weather this weekend, both during the days and sticky nights, with the following records set or tied:
Saturday high temperature: Houston Hobby Airport, 88° (tying old record from 1988) Sunday high temperature: Houston Bush Intercontinental Airport, 88° (tying old record from 1963) Sunday, high minimum temperature: Houston Bush Intercontinental Airport, 74° (beats old record of 71° from 1922) Sunday, high temperature: Hobby Airport, 90° (beats old record of 87° from 2005) Sunday, high minimum temperature: Hobby Airport, 75° (beats old record of 71° from 2015)
