Re: Il nuovo anno porterà una svolta? Ecco i primi movimenti per l'arrivo del freddo
-----------------------------------
Riecco il meteogramma!
Ci può servire per apprezzare lo stabile calo termico che avremo in quota rispetto a questi giorni.
Un abbozzo di stau per il 28 pomeriggio, poi uno stabile e relativo freddo fino alla chance disegnata per il giorno 4.
Al momento lo scorrimento delle correnti orientali sul letto umido tirrenico è visto favorire intensi fenomeni, che si verificherebbero con temperature a 850 hpa intorno ai -2 gradi. 
Ovviamente questa non è una previsione, ma serve per capire come le prospettive non siano ancora da buttare, nonostante l'indubitabile negatività del run.
