ACROSS THE PANHANDLES THIS AFTERNOON AND EVENING. WILL GO AHEAD AND
LEAVE SOME LOW POPS ACROSS THE NORTHERN CWA IN ASSOCIATION WITH THE
LIFT FROM THE WAVE MOVING ACROSS.

UPPER LEVEL HEIGHTS FALL ACROSS THE ROCKIES, A LEE-SIDE SURFACE
TROUGH WILL STRENGTHEN WHICH WILL INCREASE THE SOUTHWEST SURFACE

DAYTIME TEMPERATURES ABOVE NORMAL FOR THURSDAY THROUGH SATURDAY. A
COLD FRONT WILL HELP TO COOL TEMPERATURES BACK TO AROUND NORMAL FOR
SUNDAY AND MONDAY. TEMPERATURES WILL WARM BACK TO AROUND NORMAL BY
TUESDAY.
THE RAIN CHANCES INCREASE DURING THE WEEKEND, MAINLY ACROSS THE
NORTH AND EAST, AS THE UPPER LEVEL TROUGH MOVES FROM THE ROCKIES

MOVES OFF TO THE EAST AND AN UPPER RIDGE STARTS TO BUILD ACROSS
THE REGION.
