North America pattern shift?

Another nor'easter has begun to affect the region with light showers during the afternoon. Showers will be off and on until 3 or 4 in the morning, then the heavy rain arrives and will last all morning. Showers will continue through Wednesday morning, and may even end as some wet snowflakes. Total rain amounts will range from 1-3 inches and that will create some more rivers to flood.

Alerts: A flood watch is in effect through Tuesday night for the entire area, excluding the Cape.

Volcano eruption:

A small volcano has erupted in Iceland, and close to it is a very powerful and large volcano called Katla. The last several times the smaller one went off, it caused the larger one to have a big explosion. If the large volcano erupts it could change weather patterns. The last time Katla erupted around 1910, it was a huge eruption. It caused North America to go into a mini ice age. Temps here in New England did not make it above 0 (F) for several months, NYC got feet of snow, and the Mississippi river froze in New Orleans, LA. If Katla erupts as it has in the past, we would have a chilly summer and a frigid winter. Stay tuned in the next couple of weeks to see if it erupts.
