December 28, 2007
The upper level pattern has been one of many, rapidly moving “shortwave” troughs during the past two weeks. Now, a major shift is indicated for the first few days of 2008.
One large trough will tend to dominate the eastern half of the nation, while a ridge begins building over the west.
Texoma will be influenced by the trough: northerly wind flow will push colder air southward; a tight pressure field suggests very gusty winds as well for New Year’s Day. Although this air will not be brutally cold, overnight lows will be in the teens and 20s for several mornings next week.
If the trough shifts a bit further west, then we’ll have to watch for a colder pattern. At this moment, expect much colder nights but “not that bad” during the days…except for the wind…on New Year’s Day.
An eastward shift to the ridge should start a major warm-up by late next week.
Things look pretty dry through
Here’s wishing you and yours the very best in 2008!
