Nei iyo thermometer yemotokari isinga gara inoratidza nenzira kwayo

Pasina kupokana, waifanira kugara mumotokari pazuva rinopisa rezhizha, vhura kiyi uye uone tembiricha pane zvishandiso, izvo zviri pachena kuti zvakakwirira kupfuura chaiko. Meteorologist Greg Porter anotsanangura kuti nei izvi zviri kuitika.
