    ...Winter Weather Awareness Week in Arkansas...

    November 29th through December 3rd 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 winter of 2020/2021, and the dry winter of


    2015/2016 45.5 +4.2 12.89 +0.77
    2016/2017 46.7 +5.4 9.54 -2.58
    2017/2018 41.3 0.0 19.70 +7.58
    2018/2019 43.7 +2.4 20.03 +7.91
    2019/2020 44.7 +3.4 14.22 +2.10
    2020/2021 39.6 -1.7 11.98 -0.14

    While weather conditions varied somewhat, historic or extreme
    events were almost non-existent. There was one notable exception,
    and that was the winter of 2020/2021. In February, an Arctic
    intrusion affected areas all the way to the Gulf Coast. In
    Arkansas, temperatures were twenty to more than thirty degrees
    below normal from the 14th through the 18th. During this time
    frame, two big storm systems unleashed more than twenty inches
    of snow in central and southern sections of the state.

    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 largely
    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 /versus weak/ 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.
