DANGEROUS SWIMMING CONDITIONS ARE EXPECTED THROUGH WEDNESDAY MORNING.

LINGERS THROUGH MOST OF THIS WEEK WHILE THE UPPER-AIR PATTERN
CONTINUES TO BE CHARACTERIZED BY A TOWERING 500MB RIDGE OVER THE
FOUR CORNERS. WE REMAIN ON THE NORTHEAST SIDE OF THIS RIDGE KEEPING
THINGS RELATIVELY SEASONABLE. HOWEVER, BY THE END OF THE WEEK,
VARIOUS SHORTWAVES ENTER THE UPPER-LEVEL FLOW PRESENTING THE CHANCE
