A warm and unstable airmass developed across the Four State Region during the morning and afternoon hours of February 24th.  A vigorous upper level storm system moved eastward out of the Texas Hill Country, into the region during the afternoon.  A strong dryline developed across central Texas and pushed its way eastward into Northeast Texas during the afternoon.  The upper level storm system provided lift along the dryline for a broken line of thunderstorms to develop across Northeast Texas and Southeast Oklahoma.  Strong shear was present and as a result...widespread wind damage was reported as the squall line moved into Southern Arkansas and Northern Louisiana.  A few hail reports occurred but the bulk of the reports from the storm system were straight line wind damage.
