Wildcat Ski Resort in New Hampshire reports 5" of new snow today,
Saturday April 23, 2011. This is the 3rd snowfall in 4 days here in New
England. Though we are not setting late season snowfall records in New
England (May 1977 stands tall). But this cold & snow is part of a
much bigger and more disastrous weather pattern that will not quit.
As of this evening the preliminary tornado count for April 2011 stands at 561. Though this number will surely be reduced when the count is adjusted for multiple sightings of the same tornado, we are on the path to the most tornadoes of any months since record keeping began in 1950.
From this web sight, we see the record that stands is 543 in May 2003.
What single month had the most tornadoes?
The record for most tornadoes in any month (since modern tornado record keeping began in 1950) was set in May 2003, with 543 tornadoes confirmed in the final numbers. This easily broke the old mark of 399, set in June 1992.
The set up shows little sign of change. A series of Pacific low
pressure systems, one after the next, continues to arrive on the West
Coast of North America. But deep snow and residual winter cold are
forcing these lows southeastward toward the hot air in Central America
and Texas. Then typical of a La Nina pattern, ridging in the
southeastern United States amplifies the low pressure systems near the
Mississippi River Valley. We have a sever weather outbreak form Texas
to Kentucky right now. Then and even stronger outbreak will make
headlines mid week, this one could make this month the most tornadic on
record for the U.S.
Thanks to the lower dew points with colder air here in New England, we have been spared by most of the Violent Thunderstorm outbreaks so far this year. We have had plenty of damaging wind, typical with such temperature gradients, but not so many sever storms. Our time will come though. And it may be this week. We will warm Dramatically Wednesday through Friday, with major amplification of an Upper Trough over The Appalachians Thursday into Friday. One ingredient in our Thursday/Friday storms will be a piece of sub-tropical energy now north of Puerto Rico that will ride up the east coast Wednesday/Thursday. If this were hurricane season, we would be vulnerable to a storm coming up the coast. We may worry about that in about 4 or 5 months.
Before this warm tropical air rushes in, we will have another high pressure center to our north on Monday, pushing in an Ocean breeze and many clouds with for, drizzle, and showers. The real warmth and humidity waits for the southerly wind to return Tuesday Night and Wednesday.
