Winter forecast for 2011-2012

Postby postholer » Thu Oct 20, 2011 12:07 pm

Quoting Dr. Jeff Masters, senior meteorologist at weatherunderground.com:

"I'm often asked by friends and neighbors what my forecast for the coming winter is, but I usually shrug and ask them to catch some woolley bear caterpillars for me so I can count their stripes and make a random forecast. Making an accurate winter forecast is very difficult, as there is too much that we don't know. I've learned to expect the unexpected and unprecedented from our weather over the past two years, so perhaps the most unexpected thing would be a very average winter for temperatures. The one portion of the winter forecast that does have a high probability of being correct, though, is the forecast of dry conditions over Texas and surrounding states. Extreme droughts tend to be self-reinforcing, by creating high pressure zones around them that tend to deflect rain-bearing low pressures systems. The unpredictable AO doesn't affect weather patterns that much over Texas, so we can expect that the fairly predictable drying La Niña influence will dominate Texas' weather this winter."

His latest post makes the annual attempt to paint a portrait of what this winter will look like.
