Mese che rimarrà impresso per la lunga fase fredda che ne ha caratterizzato i 15gg centrali con anche la nevicata a cavallo tra il 6/7 che, nell'orvietano, ha portato una spolverata a Porano e qualche centimetro sopra i 550m

A livello termico chiudiamo a [b][color=blue][size=14]-2.0°C[/size][/color][/b] dalla mia media 2006/2020 ed è ovviamente l'Aprile più freddo da quando rilevo
Terzo mese su 4 in questo 2021 che chiude sotto la media del medesimo intervallo  :inchino: 

Poche le piogge, caduti 45mm a fronte di 60mm di media
