Days Per Year of 90°> Where You Live

There's always hope.

 

#1962

Haha. I'll still enjoy watching you guys get pummeled, even if it means I'm stuck under screaming southwest flow.

 

Though..1962 was a weak 2nd year -ENSO and -QBO, so maybe the unthinkable happens. Lol.

[Phil]

Either way this pattern looks like a slap in the face, given we've been roasting for 7+ weeks.

 

Heat indices were 95-100*F just a few weeks ago.

1962-63 was such a freak. Probably the blockiest NH winter of the 20th century. There was a record heat ridge over our heads around Halloween with a backside trough over you guys producing record lows for so early in the fall + snow flurries. Pretty much everyone in N. America and Europe scored that winter.

Sounds a lot like the pattern next week, haha. And yeah, the 1960s were an incredible decade for blocking. Deepest -NAOs observed since the LIA..talk about massive systematic heat release.

 

If that circulation had persisted for another few decades, the climate would probably have cooled an additional ~ 0.3C by the middle 1990s.

the 1960s saw great winters coast to coast likey one of our finest decades periolds.the 1950s were mostly a west coast feast.the real change started with the El nino winter 1957-58 which seemed to set up that 1960 periold.

I think 1957/58 started the trend to good winters, IIRC.

 

Though even back then, we didn't frequently see multi-foot blizzards like we do now. Storms dumping over 40" east of the Blue Ridge (like 2016) were unheard of between the mid-1920s and 1980s.

 

It looks like it might have something to do with the Atlantic meridional mode. Flipped positive in the 1990s, and hasn't changed since.

That top analog, yo.

I nailed that one! Haha.

90's in November

I looked at data from 1995 to present. Located 2 miles west of Pasadena on a hilltop at over 900'. I was surprised to discover 38 days at/ above 90F in Novembers over the past 23 years and one 90° day in Dec 2010.

November
1995: 90 [24]
1996: 92 [8] 96° [9] 92° [10] 90 [11]
1997: 100 [2] 96° [3]
2002: 90 [20] 90 [21]
2006: 90 [6] 94° [7] 97 [8] 92 [19] 90 [20
2007: 91 [14] 91° [15]
2008: 90 [14 91 [15] 90 [17]
2010: 94 [2] 100° [3, 97 [4] 90 [5]
2012: 92 [13] 95° [5]
2013: 95 [13] 92 [14]
2014: 90 [5] 92° [6] 91 [7] 93 [8] 91 [29]
2016: 90 [3] 94 [8] 95 [9] 90 [19] 91 [14]

All Decembers except 2002 & 2003 reported highest maximums in the 80 's

1962 did show up among the analogs when I recently looked at -ENSO years that had big western NA/GOA ridges around this time.

We've been done with 90*F+ days for awhile, but ironically enough, my body is having a rough time adjusting to the lower dewpoints.

 

This happens to me (and a few other people I know) every autumn. My lips, hands, and face are all dry/chapped. Went through an entire bottle of lotion already.

[Guest happ]

Total days 90°/ above: 68 so far. 

2016 year total: 69 days w/ five in November. It will to be hard staying under last years total but CPC predicts cooler than average for November.

[Phil]

[Guest happ]

Picked up another hot day @ 96F. 

[Phil]

Down in FL today. Swampy.

[Glacier]

Some have raised issue that the map is too broad-brush [ie. higher mt peaks in SoCal never record 90°].

I can't speak for California, but here in BC our valleys that get up to 25 days per year above 90 are so narrow that if you adjusted for elevation, you wouldn't even see these areas since 10 miles away east and west (or north and south) never hit 90 degrees.

[Phil]

That map is definitely broadbrushing. In the 21st century, DCA is averaging close to 40 days per year above 90*F, go 20 miles NW and the average drops to 20.

[Guest happ]

Yearly total is now 70 days.  Don't think there will be anymore 90's this month and a good chance of none next month. December is the coldest month of the year. Coastal SoCal has a long season of occasional hot temps. Most heatwaves begin in March; 90's in winter are often limited to compressional heating in favorable downslope areas mostly in Orange/ San Diego counties.  Low desert can also record 90° maximums during winter.
