..DISCUSSION
MEDIUM-RANGE GUIDANCE INDICATES THAT AT LEAST MODESTLY AMPLIFIED
MID/UPPER RIDGING WILL CONTINUE TO BUILD AND BE MAINTAINED ACROSS
THE PACIFIC COAST INTO THE ROCKIES THROUGH NEXT WEEK. WITHIN THE
NORTHWESTERLY FLOW DOWNSTREAM OF THIS FEATURE, SEVERAL DIGGING SHORT
WAVE PERTURBATIONS APPEAR LIKELY TO REINFORCE LARGE-SCALE TROUGHING
ACROSS THE EASTERN U.S., WHILE ALSO CONTRIBUTING TO OCCASIONAL
SURFACE CYCLOGENESIS FROM THE LEE OF THE NORTHERN ROCKIES THROUGH
THE NORTHERN AND MIDDLE ATLANTIC SEABOARD. HOWEVER, THESE ARE NOT
LIKELY TO BE ACCOMPANIED BY A STRENGTHENING SOUTHERLY RETURN FLOW
EMANATING FROM THE GULF BASIN. REGARDLESS, IN THE WAKE OF A
REINFORCING COLD INTRUSION ACROSS MUCH OF THE FLORIDA PENINSULA, AND
THROUGH MUCH OF THE GULF BASIN, EARLY NEXT WEEK, IT APPEARS THAT
BOUNDARY-LAYER MODIFICATION OVER THE GULF WILL NOT BECOME CONDUCIVE
TO APPRECIABLE INLAND LOW-LEVEL MOISTURE RETURN.
