The event began
with a cold frontal passage on February 16th, and a few severe storms
along the front. Behind the front, temperatures dropped more than 50
degrees in some areas in less than 24 hours! For a
look at the temperature falls, click here. |

The front stalled along the Gulf Coast, with west winds
aloft bringing a storm system from the southern Plains. The system
interacted with the front late on the 17th/early on the 18th, with
moisture surging northward into the cold air. |
The cold air was deep enough to support snow in
northern Arkansas. Two to as much of six inches of snow was common in
about the northern two rows of counties. For a
look at some accumulations, click here. |

In central and southern sections of the state, the cold air was more shallow...with a layer of warm air aloft. In these areas, snow
fell though the warm layer and melted...but refroze as it neared the
ground. The result was freezing rain and sleet. |
In
the picture: A sounding (temperature/dewpoint profile with
height) at Little Rock (Pulaski County) at 6 am on 02/18/2006. The
sounding showed a shallow cold airmass near the ground, with warmer air
aloft. Temperatures and dewpoint temperatures were nearly identical
through the profile, indicating that the atmosphere was nearly saturated
(with precipitation likely). In this case, freezing rain and/or sleet
occurred. |
Where sleet was predominant (central sections),
accumulations were generally under half an inch...with less than a quarter
of an inch of ice accrual where freezing rain occurred (mainly in southern
sections). |

Snow and ice mostly ended during the afternoon of the
18th...with only scattered precipitation remaining. Very cold
temperatures followed, with readings in the teens and 20s by the morning
of the 19th. There was some wind as well (5 to 15 mph), with wind chill
readings below zero at times in northern Arkansas. |
![The WSR-88D (Doppler Weather Radar) showed a wintry mix of precipitation near the Arkansas and Missouri border at 1235 pm CST on 02/19/2006.](https://webarchive.library.unt.edu/eot2008/20081107172414im_/http://www.srh.noaa.gov/lzk/images2/rad021906.gif) |

the picture: The WSR-88D (Doppler Weather Radar) showed a wintry mix of
precipitation near the Arkansas and Missouri border at 1235 pm CST
on 02/19/2006. Meanwhile, patchy light freezing rain was set
to build into southern sections of the state from northeastern
Texas and northwestern Louisiana. |

|
On the 19th, more light wintry precipitation spread into
areas close to the Arkansas and Missouri border. A mixture of light snow,
sleet and freezing rain was reported...with little additional
accumulation. This precipitation headed to the east, with an area of
freezing drizzle/light freezing rain spreading into southern Arkansas during the overnight hours of the 19th/early on the 20th.
A thin glaze of ice formed on roadways in the south...making travel
hazardous. |
