Tomorrow, on Sunday, 18th of May, expect scattered thunderstorms in the afternoon, along with possible lightning and gusty winds.
The chance of rain is high, and precipitation will be moderate. A mild temperature range, peaking at a moderately hot 29°C and bottoming out at a temperate 26°C, is predicted.
