National Weather Service notes:
New format for winter weather and non-precipitation notices --
Beginning Dec. 8 and ending May 29, 2010, National Weather
Service offices serving the state of Illinois will begin modifying
the formats of notices on winter weather and non-precipitation.
There will be experimental, bulleted notices for watches, warnings
and advisories, with a format similar to severe thunderstorm and
flash flood warnings. This change includes the products in the
table below:
These formats are easier for users to read and quickly gather
vital information during hazardous winter weather and
non-precipitation events. A product description document for these
experimental notices and examples of the bullet-formatted winter
weather and non-precipitation reports are available at
http://products.weather.gov/viewliste.php.

11th annual Skywarn Recognition Day -- This annual event is held
by each Illinois NWS office to recognize the contributions made
throughout the year by volunteer ham radio operators and storm
spotters. This year, the event will be from 6 p.m. Friday until 6
p.m. Saturday. Ham radio volunteers will attempt to make as many
contacts as possible across the United States on various radio
frequencies. For more information, visit
http://hamradio.noaa.gov/.
Multimedia weather briefings -- As a reminder, Illinois
NWS offices have started using multimedia tools to brief emergency
managers and the public about high-impact hazardous weather events.
This tool will not replace the conference calls with EMAs and the
media for hazardous events but will supplement them.
These briefings will be located on NWS Web pages. Go to
www.weather.gov
and then click on the portion of Illinois you are interested in
to jump to the NWS office that covers your area.
