The
year 2005 will be remembered for a record number of hurricanes, a lack of
rain, and a large tornado outbreak (around Thanksgiving). As you read
various weather accounts, you may not be familiar with where events
occurred in the Little Rock County Warning Area. To help you along, refer to a map by clicking
here. Onward we go... For those who are
into Winter weather, there was a snowstorm to start the year...but it
affected a small portion of northwest Arkansas. On February 1st/2nd,
snow accumulations of 4 to 6 inches were reported...including 5 inches in
the Harrison (Boone County) area. Up to 8 inches piled up at Mount Sherman
(Newton County). To check out
the event on February 1st/2nd, click
here.
Ice of a different nature occurred on April 28th/29th. Numerous
hailstorms developed north and west of Little Rock (Pulaski County), with
several reports of golfball size hail. This included areas such as Danville
(Yell County), Atkins (Pope County), near Conway (Faulkner County),
Jacksonville (Pulaski County), and just southwest of Heber Springs (Cleburne
County). The event was covered by the Cable News Network (CNN). For
more on the hailstorms on April 28th/29th, click

The hail event in April was one of the few big severe weather episodes
in the Spring. It was uncharacteristically slow during Spring, with only 1
tornado spawned in the Little Rock County Warning Area. This weak (F0)
tornado occurred a few miles west of Dardanelle (Yell County) on April
11th.
Otherwise, drought conditions began to worsen in May...with dry weather
continuing in June. In both months, rainfall was 2 to 4 inches below
normal in much of Arkansas...with some spots in northeast Arkansas
receiving less than an inch of rain for the two month period. Newport
(Jackson County), for example, reported a total of 0.74 inches of
precipitation.

There was some relief in July, with at least a couple of heavy rain
events. During this time of year (early Summer), it is common for large
thunderstorm complexes to form in the Plains and head to the east. In many
cases, the complexes will weaken as they approach the state (toward
morning), with a mesoscale convective vortex (MCV) left behind. This is a
pool of cool air aloft that eventually moves over warmer/more unstable
conditions near the ground...with thunderstorms redeveloping. That is
exactly what happened during the nighttime hours of July 5th/early on July
6th...with more than 4 inches of rain produced in portions of central
Arkansas. For more on the MCV of July 5th/6th, click
here.
And then the hurricane season (June 1st to November
30th) got cranked up. The tropics were very active, with a total of 28 named
storms! This broke the previous record of 21 storms in 1933. For
a closer look at the 2005 hurricane season, click here.
One such storm, Hurricane Dennis, reached Pensacola, Florida on July
10th...and affected areas mainly east of Arkansas as the system moved
inland. Eventually, the remnants of Dennis parked in the Ohio Valley for a
few days...with tropical moisture sitting over Arkansas. This led to a
heavy rain event on July 16th, with over 3 inches of rain in an hour near
Sherwood (Pulaski County)...and flash flooding. To
check out flash flooding on July 16th, click here.
The big hurricanes of the year (at least in the western Gulf of Mexico)
were Katrina and Rita. Both storms reached Category 5 status (sustained
winds over 155 mph) before making landfall as Category 3 (winds of 111-130
mph) systems. Katrina made landfall just southeast of New Orleans,
Louisiana on August 29th...with Rita coming ashore on September 24th. The
remnants of Rita had a direct impact on the Little Rock County Warning
Area, with 3 to 6 inches of rain (which helped the drought situation) and
11 tornadoes produced. Wind gusts of 30 to 50 mph were also common with
Rita, with a 52 mph gust at Texarkana (Miller County). For
more on Katrina, click here...and
for the impacts of Rita, click here.
The rain from Rita helped in the short-term...given that there was a
lack of precipitation in October. In fact, there were 32 days with no
measurable precipitation in North Little Rock (Pulaski County) from
September 28 through October 30th...a record dry spell.
In November, the big tornado outbreak of the year occurred. On the
27th, there were two dozen tornadoes spawned from southwest through
central and north central Arkansas...covering a 20 county area. The
strongest tornadoes were rated F3 (158-206 mph winds)...and affected portions of
Conway and Perry Counties. While there was lots of destruction in these
areas, there was only 1 fatality. This outbreak and a stormy Fall pushed
the tornado total for the year to 52. For a look at the
tornado outbreak of November 27th, click here.

The year ended on a dry note. It was the driest December on record,
with an average of only 0.75 inches of precipitation statewide. The
drought was in full swing, and continued into 2006. For
