    ...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
    2016/2017.

    WINTER AVG TEMP DEPARTURE PRECIPITATION DEPARTURE

    2014/2015 39.5 -1.8 9.68 -2.44
    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 44.6 +3.3 14.29 +2.17

    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.
