Strong southerly winds will create hazardous boating conditions across much of the region through this afternoon ahead of a cold front. Therefore, a Lake Wind Advisory is in effect for nearly all of the region today. As the cold front shifts across the area, a few thunderstorms may develop across parts of deep east Texas and eastward into much of north Louisiana and south Arkansas. However, no organized hazardous weather is expected. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... By Friday night through Saturday, the threat for thunderstorms will expand to include all of the region as a strong upper level storm system lifts northeastward across the southern Plains. The resulting increase in shear and instability will lead to a higher potential for strong to severe thunderstorms late Saturday morning and especially during the hours of afternoon peak heating. Storms may continue through early evening before gradually diminishing as a cold front shifts across the region. All modes of severe weather will be in play including a few strong tornadoes. In addition, an isolated flash flooding threat will exist with as much as two to four inches of rainfall possible through early Sunday morning. The next chance of thunderstorms will return on Wednesday with the threat of severe weather possible yet again as another very strong upper level storm system shifts east from the Rockies across the southern Plains. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, spotter networks, and amateur radio operators will not be required through Friday morning. 19
