• 12/5/2008 - More active pattern could blast the west after the 13th of December. A look at the PDO Index and late December weather for New England-Roemer
PATTERN CHANGE FOR THE WEST AFTER THE 12TH OR 13TH
If you are planning on heading out west to the Cascades, Heavenly, Lake Tahoe, Snowbird, Alta (for example), you will be in luck after about the 13th-15th of December as a pattern change will occur. Major snows, in excess of 1-2 feet may blast areas like Mt. Baker, Crystal Mountain to the Tahoe region and perhaps at least 6-12" of snow and maybe a whole lot more in the Cottonwood Valley of Utah to California. Alot more will be needed, but at least this is a start.
For the last few weeks,a strong eastern Pacific ridge, for the most part has blocked major storms from entering into places like Utah and sections of British Columbia, Alberta and the Cascades.
WHAT IS THE PDO INDEX?
Due to a climatological phenomena known as the PDO (Pacific Decadel Oscillation Index), historically, but not always, any strong eastern Pacific ridge, that would normally block storms, begins to break down later in December or January. In turn, this often opens the door for more important snows from the Tetons and Utah and the Cascades and occasionally throughout the Sierras. Though this is not written in stone, and teleconnections (As meteorologists call them) can vary from solar acivity to La Nina (right now we have a very weak La Nina at best). The east, on the hand, tends to see more freeze-thawing. Hence, after some great early season skiing the next 10 days, much of New England may see wide temperature swings and freeze thawing into mid-late month. Some snow? Yes, but also mixed precip and thawing, especially over central and southern New England after the 13th or 14th. In fact, even the middle of next week we will see readings back into the 30's to near 40 for a few days over parts of central and southern New England

About Me
Jim Roemer was given the nickname Dr. Weather from Stowe Mountain in 2001, due to his uncanny accuracy in forecast snowfall patterns, sometimes weeks in advance. The name has stuck every since. Jim has become a household meteorologist in the ski industry with thousands of skiers depending on his forecast to make both short term and longer term plans as to which slopes to hit. While many weather services have automated reports, in an age where life has become so impersonal, at times, Jim's reports add a unique freshness of honesty, exhuburance, personality and humor without sacrificing accuracy. "Second guessing computer models is what I do best", Jim says.
Jim Roemer helped develop Freese-Notis's commodity weather forecast division back in the 1980's and early 1990's and was a frequent guest on CNBC-TV and Bloomberg. Today Jim
has done considerable research and lecturing on global warming, plays competitive tennis and is a crazed skier.
