A SHORTWAVE TROUGH CENTERED OVER SOUTHERN CALIFORNIA THIS AFTERNOON WILL TRANSLATE ACROSS THE SOUTHWESTERN STATES OVER THE NEXT COUPLE OF DAYS. IN ADVANCE OF THIS FEATURE...SEVERAL MINOR SHORTWAVES EMBEDDED WITHIN THE UPPER FLOW WILL TRACK ACROSS THE FORECAST AREA MONDAY AND MONDAY NIGHT. THE GFS MODEL ACTUALLY TRIES TO BREAK OFF AN UPPER LOW OVER NORTHERN MEXICO AND BRING INTO TOWARD THE AREA LATE MONDAY AFTERNOON. THE ETA MODEL DOES NOT INDICATE THIS FEATURE...BUT STILL BRINGS MINOR SHORTWAVES ACROSS DURING THE AFTERNOON. IN EITHER CASE...A SURFACE LOW AND AN ASSOCIATED FRONTAL BOUNDARY SHOULD DEVELOP/MOVE INTO THE TEXAS PANHANDLE MONDAY AFTERNOON COURTESY OF A MORE SIGNIFICANT SHORTWAVE TRACKING ACROSS THE CENTRAL PLAINS. THE SURFACE LOW SHOULD BE CENTERED ACROSS THE NORTH/NORTHEAST ZONES BY LATE AFTERNOON...WITH A SURFACE TROUGH EXTENDING DOWN THROUGH THE EASTERN THIRD OR SO OF THE FORECAST AREA. THE ATMOSPHERE WILL BE UNSTABLE ACROSS THE AREA WITH DEWPOINTS FROM THE UPPER 40S IN THE MOUNTAINS TO THE LOWER TO MID 60S ACROSS THE EAST AND SOUTHEAST.
