WASHINGTON, D.C. -- NOAA's National Centers for Environmental Prediction (NCEP) issued an assessment of medium-range threats to the U.S. from current weather patterns. NCEP began issuing assessments during last year's El Niño, and they continue this year in part to track the impact of this winter's La Niña event.

For the period Jan. 8 through 15, NCEP forecasts a weather pattern somewhat quieter than the past two weeks. However two significant snow events are forecast.

The first, impacting areas from the Central Plains into New England is expected to occur between Jan. 8 and Jan. 10. This will be a messy storm, producing freezing rain and sleet along its southern border from Tennessee to southern Pennsylvania, but is not expected to be comparable to the New Year storm than paralyzed much of the Midwest and Great Lakes region. The heaviest snows are likely in the Ohio Valley and into New England. This system may produce significant rain for much of the East Coast, improving conditions in dry areas from Virginia north to southern Connecticut.

The northern Rockies, including parts of Idaho and western Montana, may also see significant snow over the weeklong period from Jan. 8 to 15.

Finally, the Pacific Northwest will see the return of wet weather for the bulk of the period, possibly spurring some minor flooding along the immediate coastlines of Washington and Oregon. The heaviest rains are expected early next week, with daily precipitation amounts of near an inch most days. Snow depths are expected to be relatively stable, so no major threat from snowmelt is anticipated at this time.
