NH Winter/SH Summer 2020-21 Discussion Thread

Alexandria's airport was at freezing or below for 131 consecutive hours, which was the longest since records began there in 1943!

Yep, and in reality they had their snowiest month on record in a span of just four days. Impressive stuff, they also came within 0.2" of break their daily snowfall record (they received 11.8" on the 17th, record is 12").

Little Rock also recorded their first subzero temperature since December 23, 1989 on Tuesday morning. 

Cold in Fairbanks today, they also reported light snow this morning with -37 C/-38 C temperatures:

16.0°C high in Amsterdam Schiphol airport yesterday:

A Day Of Temperature Contrasts In Melbourne
"Olympic Park in the south of Melbourne recorded a top of 23.8 degrees at 10am EDT this morning, while the airport further north topped out at 32.6 degrees at 4pm - significant differences considering they're only 20 km apart.

Northeasterly winds at the airport allowed the mercury to rise during the late morning before southerly component winds dropped temperatures a few degrees a little after midday. Winds then swung more east with a little bit of north and picked up the peak of the heat from northern inland, resulting in the top of 32.6. The southerly winds kicked in again just after 4pm and dropped temps to the mid-20's by 5pm.

In contrast, Olympic Park missed the warmer northerly component winds and was dominated by the cooler southerly air blowing across Port Phillip Bay keeping temperatures in the low 20's."

Image: Winds and temperature at 2pm EDT Saturday 20th February using the ECMWF model. The northerly winds and southerly winds can be seen over both locations at this time step creating the stark temperature difference.

"On Sunday, temperatures should be more similar between the locations with a dominant southerly flow. However, compared to the sunshine today, the skies are likely to be filled with clouds."

Here's the Paris-Orly daily anecdote. I noticed that since the beginning of the year, weekends were often significantly cooler than weekdays, so I calculated the 2021 Mo-Fr and Sa-Su averages and it indeed shows in the stats:

Mo-Fr: 7.6/2.7°C (46/37°F)
Sa-Su: 5.5/0.5°C (42/33°F)

Interesting... or not. Well, that's it for today's weather tidbit. See you tomorrow!




Sharp contrast in Karelia!

Seasonable day today, was 60 F (15.6 C) as a morning low and it's currently 77 F (25 C) with a strong easterly breeze, feels much nicer than recent weather.

Congratulations with the summer weather today in Paris!

Riga has had a nice spring day, high has been 6.5C, which is the highest high in this year so far.
