...Winter Weather Awareness Week in Arkansas...
November 30th through December 4th is Winter Weather Awareness
Week in Arkansas. The purpose of this week is to remind people
what winter weather can bring, and how to deal with
hazardous winter conditions. Now is the time to prepare
for the upcoming winter season.
During each weekday, a different winter weather topic will be
covered in a Public Information Statement...
Monday...The Outlook for the Coming Winter
Tuesday...Winter Precipitation Types
Wednesday...Winter Weather Watches, Warnings, and Advisories
Thursday...Winter Weather Safety Rules
Friday...The Cold of Winter
Climatological winter runs from December through February.
The last six winters have featured mostly warmer and
wetter than average conditions. The notable exceptions were
the cold/dry winter of 2014/2015, and the dry winter of
While weather conditions varied somewhat, historic or extreme
events were almost non-existent. Interestingly, the most recent
huge episodes of snow, ice, and severe thunderstorms occurred
when La Nina conditions were dominant, or when water temperatures
near the equator in the Pacific Ocean were colder than normal.
Since early 2012, La Nina has been infrequent and weak.
With La Nina firmly in place, the largest tornado outbreak in
Arkansas took place in January of 1999. There were 56 tornadoes
spawned. In December of 2000, two crippling ice storms occurred,
and remain one of the largest natural disasters in state history.
In February of 2008, a tornado tracked 122 miles through seven
counties in the north and west. This was a record long track
in the state. Another devastating ice storm hit the north in
January of 2009. Finally, one to two feet of snow buried the
Ozark Mountains in February of 2011. In April and May, an
astonishing 67 /of the yearly total of 75/ tornadoes were
counted. There was also record flooding along the Black and
lower White Rivers.
Heading into this winter, it appears that La Nina will take charge
again. In fact, a moderate to strong La Nina is expected, and
that increases the chances of history being made in Arkansas
in the months ahead. It also favors a warmer and drier pattern
overall across the southern United States.
