Big Events (2008) |
 |
| |
| 2008 has been a year of extremes in Arkansas. The
year started with a huge tornado outbreak on January 7th/8th
(especially in southwest Missouri), with a wind episode and gusts
over 50 mph on January 29th. |
 |
On February 5th, killer tornadoes took the lives
of fourteen people...with one tornado tracking a record 122 miles!
Heavy snow blanketed northern and western sections of the state on
March 6th/7th, with accumulations over a foot in some areas. |

a boat factory at Clinton (Van Buren County) on 02/05/2008. Fourteen
people lost their lives in Arkansas on this day.

| Then the flooding began after more than eight
inches of rain fell in parts of the north and west on March 17th
through the 19th. Area tributaries such as the Buffalo, Spring,
Black and White Rivers experienced Top 10 crests on record. |

| A dozen tornadoes were spawned on April
3rd/4th across central sections of the state...including the
Little Rock (Pulaski County) area. There were high water problems
as well. This was followed by more heavy rain/flooding on April
8th through the 10th. |
| Why
So Active? |
|
A La Nina (cooler than normal water in the equatorial Pacific Ocean)
pattern was in place as 2008 began. The southern branch of the
jetstream (the Subtropical Jet), which normally flows south of
Arkansas during the Winter/early Spring months, was drawn northward.
This provided more warmth and moisture than usual, with incoming
storm systems energized and producing more extreme weather events
than normal. The severe weather season (usually from March through
May) also got an early start, with tornadoes in January. This was
also the case in 1999 (a La Nina year), with 56 tornadoes on the
21st/22nd (a record outbreak in Arkansas). |
 |
Killer tornadoes returned on May 2nd, with seven
people lost. Five of the deaths were caused by a tornado that
tracked 45 miles. More tornadoes followed about a week
later (on the 10th), mainly in central and southern Arkansas. |
|
In the picture: A feed mill was heavily damaged by a
tornado (rated EF3) about 3 miles north-northeast of Damascus (Van Buren
County) on 05/02/2008. Seven people were killed on this day.

Many Tornadoes? |

|
Through May, there was a preliminary total of
68 tornadoes in Arkansas (as published in Storm
Data). Apparently, there have been no tornadoes spawned
since May. In a normal year, there are 26 tornadoes. |
On June 1st, an MCS (Mesoscale Convective System) swept across the
region with widespread wind damage reported. Then Summer arrived
and the weather slowed down as it usually does in
Arkansas.
Just as it got hot (in late July/early August), a front moved
into the region and stalled. There was lots of rain and much
cooler temperatures on August 9th through the 12th. Some locales
in southern sections of the state received over 10 inches of
precipitation! Usually, tropical systems are responsible for
such heavy amounts in Summer. Not this time.
This is an incredible chain of events. It is
rare to have such extremes occur in a calendar year. It is a
once in a lifetime experience. |
