Severe Weather on April 24-25, 2007 |
 |
| |
 |
A rather significant storm system approached Arkansas from the
southern Plains on April 24th. The system dragged a cold front
toward the region, with showers and thunderstorms along and ahead of the front.
As of 3 pm CDT on the 24th, severe storms
developed from south central Kansas into central Oklahoma into north
central Texas. |
| In the picture: The
satellite showed a storm system ("L") in southeast
Colorado, and severe storms along a cold front from Kansas to
Texas as of 3 pm CDT on 04/24/2007. |
| These storms pushed into Arkansas by 8 pm CDT. There were at least a couple of bow echoes noted, with trees and power
lines downed and some structural damage from Clarksville (Johnson
County) to Mountain View (Stone County), Salem (Fulton County) and
Newport (Jackson County). These areas are in northern and western
sections of the state. |

The WSR-88D (Doppler Weather Radar) showed a bow echo (backward "C"
shaped line of storms) tracking through Clarksville (Johnson County) as
of 815 pm CDT on 04/24/2007. There was rotation ("L") on the
northern end of the bow (bookend). |
| Bow echoes are backward "C" shaped lines of
storms. The shape is created when strong to damaging winds cause the
leading edge of the lines to bulge forward. Toward the ends of the
lines, there are areas of rotation called "bookend vortices"...with
tornadoes favored toward the northernmost bookend. Such a bookend
tracked near Ozark (Franklin County), with a weak tornado spawned.
Otherwise, straight-line winds were responsible for the damage reported,
with gusts up to 80 mph.
The bow echoes were gone as of 12 am CDT on the 25th. However, a few
hours later, storms in Texas built into southern
Arkansas...with isolated severe weather. For example, penny size hail
was reported at Monticello (Drew County).
|
 |
In addition to wind damage and hail, there were areas of heavy rain.
One to two inch amounts were common, with locally over three
inches. |

Rainfall in the 24 hour period ending at 7 am CDT on 04/25/2007.
"E" is estimated precipitation. |
| In the twenty four hour period ending at 7 am CDT on the
25th, the heaviest rain was across the northwest half of the state. Mount Ida (Montgomery County)
received 3.45 inches of rain, with 2.77 inches at Hot Springs (Garland
County) and an estimated 2.50 inches at Russellville (Pope
County). After 7 am CDT on the 25th, rain lingered in southeast
sections of the state...with additional amounts over an inch in spots.
Monticello (Drew County) measured 1.37 inches before precipitation ended
later in the morning. |
| Round one of this event exited to the east toward the noon hour of
the 25th, with a brief lull following. The main system and
cold front still loomed to the west, with the front arriving
in western Arkansas during the afternoon hours. With some warming to destabilize
the atmosphere, storms redeveloped along the
front...but mostly stayed below severe limits. |

| In the picture:
The satellite showed clearing in western Arkansas as of 12 pm CDT on
04/25/2007. Temperatures warmed into the 70s, with a cold front
approaching from the west. Puffy cumulus clouds popped up around
the front, with the clouds becoming storms during the
afternoon. |
