Summer?  ...or not?

The weather's been completely freakish the past couple of days.  The weather report has been completely unreliable, (which is partially because they have a decades-old outdated weather satellite) and even the ol' look at the sky routine didn't work out this weekend.  Take Saturday.  Weather forecast, "Cloudy throughout the day, then rain".  I look into the sky in the morning.  Not a single cloud in sight.  Day ends up being a scorcher (I turned another shade darker).  Around 3pm, clouds suddenly roll in from nowhere, and out pours merciless sheets of rain.  Several hours later, the rain past, the clouds were gone, just as quickly as they came.  Ok, who's playing with the weather machine here!?  This is not funny...  Man, soon it'll be hot in the morning, snowing in the afternoon.
