2008 Forecast Verification Summary

Weather during Winter 2007 / 2008 and Summer 2008 have had largely unexpected Energy Sector implications to those not advised of Dave Melita’s accurate long range forecasts.

At the end of winter of 2007/08 the largely unexpected low natural gas storage condition made the upcoming summer forecast all the more critical. The fundamental basis of Dave’s forecast issued May 2008 was that summer 2008 would average much more moderate than the excessive heat of the preceding summer 2007 in the major energy consuming areas of the Midwest and East.

November 12 - Long Range Summary

Frigid week ahead across the Eastern half of the country; as the coldest temperatures of November 15°-20° below average peak in the Plains and Midwest early week (Monday-Tuesday), and near 15° below average in the East midweek (Wednesday-Thursday). Latest models are colder for longer especially in the Northeast as more widespread interior snow than previously forecast accompanies a coastal storm on Tuesday, and is followed by development of another storm along the East Coast next weekend (Nov 17-18).  However, at the same time fundamental late week pattern change is certain to be underway, flooding the western two thirds of the U.S. with mild Pacific air by the end of the 6-10 day period. All models agree this warm airmass will continue to advance eastward during the 11-15 day period, though some runs delay full arrival of above average temperatures into the Northeast and northern md Atlantic region until later in November. Regardless of timing details in full establishment of coast to coast above average warmth, contraction of polar air into northern Canada during Thanksgiving week in concert with low amplitude flow virtually ensures a mild end to November and 1st half of December across the U.S. However, the 30-day MWA ensemble is beginning to sense arrival of true arctic air to southwestern Canada in early December, setting the stage for a colder 2nd half of the month across the majority of the U.S.


If your business or career depends on correctly predicting the weather, you can follow the pack or you can get ahead with MWA’s proprietary models and expert forecasts.
