A COLD FRONT WILL CONTINUE TO MOVE EAST OF THE AREA
TODAY, PULLING IN SUBSTANTIALLY COOLER AND MORE MOIST AIR. EVEN
THE WARMER SOUTHERN HALF OF THE AREA WILL SEE INTERIOR HIGHS IN
THE 70S WITH MINIMUM RH AROUND 30 PERCENT. MODERATE NORTH WEST
WINDS WILL MIX ACROSS THE AREA TODAY. A BRIEF SHOT OF GUSTY
NORTHEAST WINDS TONIGHT AT HIGH ELEVATIONS WILL HELP QUICKLY DRY
CONDITIONS BACK OUT. SEASONABLY MODERATE CONDITIONS WILL PERSIST
THROUGH THE WEEKEND WITH WARMER AND DRIER WEATHER EARLY NEXT
