Lightning strikes thursday morning Dec 5th! Yellow dots are the strikes, along the coast from 61N north to a cluster at the Arctic Circle and a single strike further north cred: Twitter.com/meteorologene
Also from same source: Up to gale force wind at the platรฅberget mountain (424 m ASL) near Longyearbyen on Svalard with gusts up to 32.9 m/sec. Large low going far north.

I almost forgot to mention. As bad as November was, we had 4-5 storm days.

That's why I prefer to live at slightly higher altitudes (like back to my village): winter fogs and temperature inversion. This picture was taken this morning just E of Grenoble, and some hundredths of meters higher:  (Source: www.meteo-grenoble.com ) Up in there it was a lovely sunny morning, while Grenoble was covered in cold and thick fog. This morning at 8 am the temp in the closest weather station at the bottom of the valley (220 m) was -1.2ยฐC, while the places at higher altitude had temps above freezing even well above 1000 m (can't be more precise because the place of the picture doesn't have a weather station). The view of the fog from above is also definitively more interesting than the one of the fog itself... anyway, at least today all the valley cleared up during the morning. |

Yeah, nothing good about valley fog and inversions. You can't go wrong with higher altitudes! |

Strewth, seconded the above post RE higher altitudes.^
Valley inversions are not my billy of tea (esp. leeward valleys); too much diurnal range in winter.

very cold morning, coldest of the season after the coldest day of the year. Williamstown, MA (where I was staying) reached 1ยฐF, North Adams reached below 0ยฐF. Temperatures Sunday morning 8 am  zooming into western Massachusetts UHI in NYC kept lows no colder than the upper 20s, but just a bit north was 10ยฐF colder. Clear, calm night, perfect conditions for strong UHI and radiational cooling elsewhere via wrh.noaa.gov/map/ |

was traveling through the Hudson Valley in the morning; low clouds everywhere. felt like a temperature inversion. moist air had moved in aloft but had been very cold for early December and ground was snow covered. Vertical temperature showed a strong temperature profile hiked Greylock on Saturday. Felt like at the summit (3500 feet / 1100 m) I had only almost reached a cloud layer and the big puffy cumulus suggested a steep lapse rate |

Warm front came through overnight, got to 51 (11 c) at 3 am this morning before the cold front came through.
Back to windy and mid 30s by noon.
That winter warm fronts always take place overnight fascinates me. Not sure why it is, just seems like the timing of every front is it warms in the evening, peaks overnight and then crashes in the morning.

And max today was 12 am, weird how often that happens. |
