Second Chase of the Year Looks to be Approaching














After a nice weekend out of town and away from the internet it’s time to get prepared for the next chase adventure. Models are starting to converge on a likely chase day this coming Thursday across the southern Plains. Here is a map of the current thinking of the greatest threat area.

During Wednesday night into Thursday morning as WAA takes over and the trough starts to lower heights. Widespread convection will take over from northern Texas north to Kansas. This could hinder instability but a veered 700mb by late morning into early morning. Should allow some separation and clearing along the dry line across the Texas panhandle and western north Texas.

Here are couple maps to compare from the 12z NAM and 12z GFS
