NOAA's
FEBRUARY OUTLOOK BRINGS ON THE CHILL
Weakening El Niño To Exert Little Influence
Feb.
1, 2007 � Following an overall mild December and most of January, the
current chill over much of the U.S. will persist through early February,
according to seasonal forecasters at the NOAA
Climate Prediction Center. Below-normal temperatures are expected
to dominate the central and eastern part of the country through early
February with more moderate temperatures projected for the final weeks
of the winter season. Climatologically, winter is comprised of the months
of December, January and February. (Click NOAA image for larger

"This
winter got off to a very warm start, but it is ending with more seasonable
temperatures and precipitation over most of the U.S.," said Mike
Halpert, meteorologist at the NOAA Climate Prediction Center. Last November,
NOAA's winter outlook called for warmer-than-normal temperatures, although
cooler than last year's very warm winter season. "With one month
to go in the season, that forecast is shaping up quite well." (Click

NOAA's
temperature outlook for February favors above-normal temperatures over
much of the West, northern Plains and much of Alaska with near-average
temperatures in the Southeast, and below-average temperatures in parts
of the Midwest, Northeast and mid-Atlantic. February temperatures in
the western Great Lakes, southern mid-Atlantic, Tennessee Valley, Southwest
and Hawaii have equal chances for being above-, near- or below-average.
Precipitation
during February is expected to be above average throughout much of the
southern U. S. from California to Florida and the south Atlantic Coast,
and in southern Alaska and below median in the Missouri Valley, the
western Great Lakes, the Alaskan Panhandle, much of Washington state
and Hawaii. Equal chances of above-, near-, or below median precipitation
is anticipated elsewhere. (Click NOAA satellite image for larger

Meanwhile
in the tropical Pacific Ocean, El
Niño conditions are weakening as water temperatures have
trended towards normal during recent weeks. "Any El Niño-related
effects over North America should be minimal during the remainder of
the winter season," said Vernon Kousky, research meteorologist
at the NOAA Climate Prediction Center. "A return to neutral conditions
in the tropical Pacific is expected this spring."
NOAA
forecasters caution everyone to keep safe this season. Cooler temperatures
combined with above-normal precipitation can often mean a wintry mix
of sleet, snow and freezing rain. The NOAA National Weather Service
has a wealth of weather safety information, including news and information,
online to help keep you ahead of the winter storm. (Click NOAA

NOAA, an
agency of the U.S. Commerce Department,
is celebrating 200 years
of science and service to the nation. From the establishment of
the Survey of the Coast in 1807 by Thomas Jefferson to the formation
of the Weather Bureau and the Commission of Fish and Fisheries in the
1870s, much of America's scientific heritage is rooted in NOAA. NOAA
is dedicated to enhancing economic security and national safety through
the prediction and research of weather and climate-related events and
information service delivery for transportation, and by providing environmental
stewardship of the nation's coastal and marine resources. Through the
emerging Global Earth Observation System of Systems (GEOSS),
NOAA is working with its federal partners, more than 60 countries and
the European Commission to develop a global monitoring network that
is as integrated as the planet it observes, predicts and protects.
