Volcanic eruptions release certain gases such as sulfur dioxide and other stuff from the earth's interior...
Some of these gases lower atmospheric temperature...

When Mt. St. Helen's erupted it was in May, no it did not affect the weather. But when Krakatoa erupted it did, the explosion from it was 26 times greater the the strongest H-Bomb. and was heard over one/thirteenth the distance of the earths surface. The global effects from it were recorded as record lows on our eastern seaboard. I do believe that this happened during the summer months of 1883. I could be wrong. Merchant sailor at the time have witnessed the incident and have recorded it in their ship's log. So it has been well documented.
I was about 7 at the time Mt. St. Helen's erupted in 1980 and live in Portland at the the time. If another eruption occurs, the blast would have to pretty much level the rest of the mountain for such an affect on the climate for a short time.

Any effects on climate were short lived and were due to massive amounts of ash being projected in the air, lowering temps ever so slightly.
