There might be 1\4 to 1\2 an inch of snow in northwest Alabama on grass. I wish we would get some snow here in south Alabama, I could tolerate the cold more if it would at least come with some snow!

Most of the time we track the storms on the maps, Well, heres a look at the Projected High Pressures coming up from the latest GFS12z run. Arctic High after Arctic High. Each just a tad bit colder travelling over Canadian Snowpack.

Click "Loop All" to see in action.
  • Top left pretty much Current map, High pressure about to drop down towards Great Lakes
  • Top right next one early next week will stay and curl in Canada
  • Bottom left for late next week digs way south and that might help the East coast potential snowstorm for around the 23rd
  • Bottom Right way out in future for 2 weeks shows to drop into the Northeast

Memphis has had bad luck in snow totals since the Pyramid was built, and there's a very good reason - the curse the heatmongers put upon it. Without demolition the Curse of the Pyramid shall be upon Memphis .

Now, an exercise for the reader: compare the previous picture I posted to the radar now and see where some heavy-looking returns are breaking out - a line roughly from Monticello down through Cookeville and south-southwest of there:



Notice that this corresponds pretty closely to two rises in elevation, the eastern Highland Rim and the Cumberland Plateau. Elevation matters a lot; this is a cumulative 1500 foot rise, but even much slighter rises have been known to make a difference. If that rise was 500 miles to the west Memphis would have gotten a good snow this morning. This is why it's better at the top than at the bottom, why I'm so fond of mountains, rises, and plateaus, and why I include all of that in abundance when I indulge in a bit of worldbuilding.

Northeast temp departures 1st week of January vs 2nd week. U.S Month to date on bottom.

Been a Cold Northeast last 7 days but not extreme, historic or anything interesting. Figures Midwest and Great Lakes areas have more negative departures. South Florida & South Texas sticking out there.

Perhaps not historic, but can you think of any colder weeks in recent years? It has to be one of the more intense ones. Less so for southern than northern New England.

I guess -2C qualifies as well below average for them. Paris (Orly) according to ECMWF 10 day doesn't go below -2C, and every single day has a high of about 3-5C. Talk about wimpy cold. As I said, at the end of the month we will probably be 20F below average.

London weather forecast 14 days - Rain risk - Wind direction - HDD CDD

Below average every day apart from the last day, which is average. That 3c day will feel very cold! We had a 3.2c high on 4th January, the last time before that was 26th March 2013.

Recent years? Hell yeah. But to find "as cold" per temperature, you're limiting yourself to just Januarys. What about using departures instead of temps? We sure did have weeks as below normal as this.

I'll admit I'm impressed at the length of below normal temps now. (wasn't just in and out) Going past 10 days now with the daily mean below normal.

There were 2 in January last year:

Arctic Shots 2014 VS Arctic Shot 2015.

BDR: Bridgeport, CT

January 01-09, 2014 (9 Days)
Average Temp: 22.3° (5th Coldest on record)
Max Average: 31.7° (7th Coldest on record)
Min Average: 13.0° (3rd Coldest on record)

January 22-30, 2014 (9 Days)
Average Temp: 19.1° (3rd Coldest)
Max Average: 25.9° (3rd Coldest)
Min Average: 12.3° (5th Coldest)

January 6-14, 2015 (9 Days)
Average Temp: 22.9° (10th Coldest)
Max Average: 29.4° (9th Coldest)
Min Average: 16.4° (11th Coldest)
