WEATHER OR WHETHER ?

THESE WEATHERMEN DON'T KNOW WHETHER THEY'RE COMING OR GOING. TODAY CALLED FOR RAIN ALL DAY. I ALMOST HAD TO GO TO THE SUN SCREEN.ITS THE MIDDLE OF JANUARY AND WE HAVEN'T SEEN AN INCH OF SNOW YET. I DON'T NEED SCIENTIST TO TELL ME THINGS ARE NOT RIGHT. WEATHER PATTERNS CHANGING TOO RAPIDLY.NOT A GOOD THING.
