February 2007 Storm Report |
 |
| |
| Short Weather Summary |
| |
| It
was cold to start February, with widespread light snow on the 1st. Some
light icing followed on the 9th across central sections of the state.
The pattern then changed, with warmer conditions and severe
thunderstorms. Several tornadoes were spawned on the 24th in southeast
Arkansas. Even with all of the active weather, the month finished with
below normal precipitation. |
|
| Record low temperatures were confined to North Little
Rock (Pulaski County) in mid-February. The records occurred at the end
of a cold period, with warmer weather to follow. Check
the records below... |

| A Cold Start |
|
| The Polar Jet (northwest wind flow aloft) was active
during the first half of the month, with storm systems driven toward
Arkansas from Canada. The systems generally did not have much moisture,
but there was enough to produce 1 to 3 inches of snow across northern
and central sections of the state from January 31st into February 1st. |
|
On the 9th, there were only trace amounts of precipitation
across central Arkansas...but it was in the form of freezing rain. It
was too warm aloft to support snow, and a thin glaze of ice caused
numerous accidents from Little Rock (Pulaski County) and Searcy (White
County) to West Memphis (Crittenden County). |

| In the table:
Temperatures aloft were above 32 degrees from roughly 4500 feet to 7700
feet at North Little Rock (Pulaski County) on 02/09/2007. Very light
snow fell through this warm layer, with freezing rain resulting. |
| Getting Warmer/Heavy Rain |
|
| By the 13th, there were signs that the Subtropical Jet
(southwest wind flow aloft) was ready to take over...with warmer air and
more moisture briefly surging into the region. A storm system arrived
from the southern Plains and tapped into the moisture. The led to heavy
rain in northern and western Arkansas. |
|
| In the picture:
Twenty four hour rainfall as of 6 am CST on 02/13/2007. |
| Rainfall amounts in these areas were generally between
one and two inches...with locally up to three inches. Twenty four hour
amounts as of 6 am CST on the 13th included 2.17 inches at Fort Smith
(Sebastian County), 1.91 inches at Harrison (Boone County), 1.88 inches
at Russellville (Pope County) and 1.83 inches at Mountain Home (Baxter
County). |
|
| The door to Canada was pretty much closed to end
February, with the weather more like Spring. On the 24th, it was evident
that the first severe weather outbreak of the year was set to
unfold...and it did. |
|
Five tornadoes were spawned in southeast Arkansas, with
the worst damage at Dumas (Desha County). Fortunately, there were no
fatalities...but 27 people were injured. |
