On the heels of the first winter storm and historically cold temperatures observed earlier in the week across all of the Southern Plains and much of the Lower Mississippi Valley, a second significant winter storm developed across much of these areas from February 16th-18th, with areas of snow, sleet, and freezing rain (some heavy) falling across all of North Louisiana. Strong forcing and moisture associated with the next upper level trough to move atop the extensive arctic air mass in place resulted in widespread snow and sleet totals of one to three inches, with isolated higher amounts in excess of five inches over areas bordering the Arkansas state line. Strong overrunning of warmer air atop the shallow freezing air mass in place resulted in areas of freezing rain developing over the southern and eastern sections of North-central Louisiana, with ice accumulations of a tenth to a half inch observed.
The following are snow and sleet totals that were recorded at various locations across North Louisiana from this second winter storm:
Caddo Parish: Shreveport Regional Airport: 2.5 inches, Shreveport Southern Hills: 2.3 inches, 13 NNW Shreveport: 1.5 inches, Keithville: 1.1 inches.
Bossier Parish: 4 W Plain Dealing: 5.3 inches, Red River Research Station (South Bossier City): 4.1 inches, 5 NW Bossier City: 3.0 inches, Benton: 2.5 inches, 4 S Bossier City: 1.0 inches.
Desoto Parish: Stonewall 5 NE: 1.5 inches, Mansfield: 1.0 inches.
Webster Parish: Sarepta: 4.0 inches, Minden: 2.0 inches.
Claiborne Parish: 1 N Homer: 3.5 inches.
Lincoln Parish: Choudrant: 1.5 inches.
Ouachita Parish: 2 SSW Swartz: 1.2 inches, Monroe Regional Airport: 1.2 inches.
Jackson Parish: Jonesboro: 0.1 inches.
Sabine Parish: Converse: 0.1 inches.

The following are ice accumulations from freezing rain that that were recorded at various locations in North-central Louisiana from this second winter storm:
Caddo Parish: 3 SW Shreveport: 0.13 inches.
Desoto Parish: Stonewall: 0.10 inches.
Red River Parish: Coushatta: 0.25 inches.
Bienville Parish: Arcadia: 0.15 inches.
Claiborne Parish: 1 NNW Lisbon: 0.10 inches.
Lincoln Parish: Choudrant: 0.10 inches.
Ouachita Parish: West Monroe: 0.50 inches, 1 NNE Monroe: 0.30 inches, 2 NW Monroe: 0.15 inches.
Caldwell Parish: Columbia: 0.25 inches.
Jackson Parish: Jonesboro: 0.20 inches.
Winn Parish: Winnfield: 0.25 inches.
La Salle Parish: Jena: 0.25 inches.
Grant Parish: Dry Prong: 0.20 inches.
Natchitoches Parish: Natchitoches: 0.25 inches.
Sabine Parish: Many: 0.10 inches, 1 W Zwolle: 0.10 inches.
When combined with the previous winter storm on the 14th-15th, widespread snow and sleet totals of two to five inches were observed across much of North Louisiana, with isolated higher totals of six to ten inches along the northern tier parishes bordering Southern Arkansas. In addition, widespread ice accumulations of a tenth to near a half inch of ice accumulated on trees and power lines with the second winter storm across the southern and eastern sections of North-central Louisiana. These totals crippled the region, making driving nearly impossible, with rolling blackouts further aggravated by the additional power outages the snow and ice were responsible for. In all, over 100,000 customers lost power from this second winter storm across Northern and Central Louisiana.
The weight of the snow and ice from these two back to back winter storms also resulted in numerous metal carport canopies collapsing across North Louisiana, with many homes and cars damaged. A portion of the roof at the Hirsch Coliseum at the Louisiana Fairgrounds in Shreveport also collapsed under the weight of the ice and snow as it began to melt on February 22nd, as it slid down the slanted metal structure onto the flat-roofed additions to the building. Extensive damage was done to the food preparation area, the hockey team's weight room, the team's laundry facility, and a woman's lavatory. In addition, a fence on the west side of the building was damaged, as was a local car dealer's display vehicle in front of the Hirsch.
