Look at the 4th house and planets in it as the main forcus. Examine the condition of the ruler of the 4th house and its aspects. Look at the Moon's sign and its declination and apogee/perigee then look at the other angles. Most extreme weather happens at maximum declination north or south. The Asc is East so if you normally experience bad or good weather from this direction then try not to have malefics rising. Similarly with the Dsc which is West.

Here are a few items.

Moon = Moisture, Precipitation
Sun = Heat and seasonal expectation
Mercury = Wind ( usually Westerlies)
Venus = Pleasant weather
Mars = extreme heat or mild storm
Jupiter = (benasp) Balmy (malasp) thunderstorms
Saturn = Cool, dry (ben) or bitter winds
Uranus = Lightening, cloudbursts, hail
Neptune = fog, mist , sea frets, earthquakes!
Pluto = Extremes of weather - sudden change.

Hope this helps.
