ROCKIES. IN RESPONSE LOW AMPLITUDE SHORTWAVE UPPER RIDGING WILL
BUILD OVER THE AREA TODAY. IN ADDITION, IN RESPONSE TO THE UPPER
TROUGH MOVING INTO THE CENTRAL/NORTHERN ROCKIES, LEE CYCLOGENESIS
WILL BE ONGOING TODAY AS A SURFACE LOW DEEPENS OVER WESTERN
NEBRASKA/NORTHEASTERN COLORADO. THIS WILL ALLOW THE PRESSURE
