NH Winter/SH Summer 2020-21 Discussion Thread

And according to first class sources like this, that happens very often! 
For now an extreme snow event is expected in Britain, as we can read about in that very reliable source.

rain on snow caused a big spike in water levels, well above normal for this time of year (usually on the low side this year). northern New Hampshire river; drains most of the White Mountains



unusually dry summer there, you can series no recovery and long decline after early July thunderstorms. Conneticut River near here drained a large area, some of which got summer storms so had some late summer recovery. Similar recent spike even though it's a much larger river



Green River, little very shallow river, gauge is 10 miles north of me



river warms up to about 80°F on hot summer days; river is mostly shaded, a sun exposed river might reach closer to the air temperature max (high 80s for weeklong stretches). So rivers in the shade have a mean temperature about the daily mean and max temperature a few degrees cooler than daily max

That's a distance of 1100 km /700 miles. Probably could find a 50°C range in British Columbia in winter occasionally, but its geography is rather similar (though inland mostly an elevated plateau). What was inland Norway at Alesund's latitude like (such as Dombås or Oppdal)?[/quote]

Not very cold there, Dombås a low of -4.9C at that hour. 

Larger range internally in the far north, Torsvåg high -5.4C at the coast NW of Coavdathmohkki at the same time. 

January looking to begin on a milder note, I’m hoping that doesn’t change.

The cold and snow lovers have already begun to panic.

Christchurch had some miserable Xmas weather. Only one decent high and most days below 20 C plus rain every day. Only proberly sub-polar climates see this kind of weather in mid-Summer 

Check this shit out. Unbelievable, unthinkable, absurd, beyond all reality levels of cold this morning in SE Sth Aus. 28th Dickcember 2020.

Snowy weather conditions over the most of north Italy between the last night and this morning, with cold enough temperatures to allow accumulation on the ground not just in the elevated areas, but also in large parts of the Po valley (in particular over Lombardy) or in Liguria.


 ^ temperature map for this morning at 7 am




^ Milan city center, in some parts of the city the snow accumulation is quire remarkable


Some snow also along the Liguria coast, that's quite uncommon as well


This is from Celle Ligure, west of Genoa.

@josecanyousee97 I'll tag you from here – NWS is still forecasting ~5" of snow for Wednesday night, though with the possibility of freezing drizzle Thursday morning
