About Wind Chill 
Winter in Arkansas is generally not harsh...at least not as brutal as in areas farther north. Even so, Arctic fronts make it this far south at times...and it can become cold. The question is:  How cold does it get and how should you protect yourself when temperatures plummet?
During the Winter months, temperatures will periodically drop below freezing (32 degrees)...with readings below 0 degrees on rare occasions. Now let's factor in the wind. With increased wind speeds, it feels colder than it actually is.

A Wind Chill Index Chart is shown above. For an image, click here.
The "wind chill index" is considered dangerous when temperature and wind speed combine to make it feel like 0 degrees or lower.  For example, using the chart above...a temperature of 15 degrees with a wind speed of 25 mph net a wind chill index of -4 degrees. Other than the chart, try using our meteorological calculator by clicking here.

When wind chill index values reach 0 degrees for several hours over a fairly large area (with a wind speed of at least 10 mph)...the National Weather Service will usually issue a Wind Chill Advisory.

When wind chill index values reach -15 degrees for one hour over a fairly large area (with a wind speed of at least 10 mph)...a Wind Chill Warning may be posted.

Current Wind Chill Index Values
NOTE: For Wind Chill Index values, look for WCI in REMARKS. If WCI is N/A (not available), then there is data missing such as temperature (TMP) or wind speed (WIND)...or WCI is above 35 degrees.
