Severe Weather Scrapes Region
April 6, 2003

Most areas of north Louisiana dodged the bullet but severe weather was indeed scattered throughout the region.  Mother Nature gave us a one-two punch.  Early Sunday morning storms fired ahead of a northward moving warm front.  Some of the storms became severe and were even warned for tornadoes indicated by Doppler radar.  As of this writing, no confirmed touchdowns had been reported; although, a tornado did touch down in northeast Texas.  Most of the damage reported came from Richland and other northeast Louisiana parishes.  Only a few limbs and small trees were broken or uprooted.  A few reports of shingles torn from roofs occured in Richland parish along Louisiana Highway 15 between Alto and Archibald.  Reports of hail were also received.  For the most part, hail was confined to 1/4 to 1/2 inch.

Minor Damage Reported So Far...

A Doppler warned tornadic thunderstorm caused this damage prior to noon CDT this Sunday, April 4 between the communities of Alto and Archibald along Louisiana Highway 15.  The storm had a tornado warning with a well developed mesocyclone.  However, no tornado touchdowns were sighted.  The wind damage path was several miles in length with estimated winds of 45-55 mph (based on tree damage).  Some residents also reported shingle damage to their roofs.

Below are pics of the thunderstorm as it approached the area some 3-5 miles west of the town of Mangam, Louisiana.  The photos show the large mesocyclone.  Low level scud was sweeping rapidly into the storm from the northeast and the southeast.  Occasional cloud rotation was observed with this storm however the rotation was not sustained for any length of time.

A second round of severe weather developed by early afternoon in the form of a broken squall line over northeast Texas.  Imbedded supercells formed.  One developed a tornado in Rusk county.  The line advanced eastward dropping very heavy amounts of rain (2-4 inches) with flash flooding.  A supercell developed over Jackson parish and moved east taking aim on the Monroe/West Monroe area around 5PM.  The skies turn quite dark.  A photo of the storm's mesocyclone is shown below.
