DISCUSSION...
UPPER RIDGE OVER THE SOUTHWESTERN STATES AND THE CENTRAL ROCKIES
WILL BUILD EAST ACROSS THE PANHANDLES EARLY THIS WEEK. THE UPPER
RIDGE IS EXPECTED TO SHIFT EAST AWAY FROM THE FORECAST AREA BY
TUESDAY AS A SHORTWAVE TROUGH OVER THE CENTRAL AND SOUTHERN ROCKIES
APPROACHES FROM THE WEST. ISOLATED CONVECTION COULD AFFECT THE
WESTERN OKLAHOMA AND NORTHWEST TEXAS PANHANDLES BY MONDAY NIGHT AND
AGAIN BY TUESDAY AFTERNOON AS THE UPPER TROUGH SLOWLY PUSHES EAST
INTO THE CENTRAL PLAINS STATES. UPPER RIDGE THEN BUILDS BACK OVER THE
PANHANDLES AROUND THE MIDDLE OF THE WEEK BEHIND THE DEPARTING
SHORTWAVE TROUGH.

UPPER RIDGE THEN SHIFTS EAST AWAY FROM THE PANHANDLES LATE THIS WEEK
AS ANOTHER UPPER TROUGH APPROACHES FROM THE GREAT BASIN REGION AND
WESTERN STATES. BETTER CHANCES FOR CONVECTION ACROSS MOST OF THE
FORECAST AREA LATE THIS WEEK INTO THE UPCOMING WEEKEND AHEAD OF THE
UPPER TROUGH. SURFACE TROUGH ACROSS EASTERN NEW MEXICO NORTHWARD INTO
THE CENTRAL ROCKIES AND CENTRAL PLAINS STATES WILL ALSO HELP TO
INITIATE CONVECTION MAINLY ACROSS THE WESTERN HALF OR WESTERN TWO-
THIRDS OF THE PANHANDLES FRIDAY THROUGH THE WEEKEND.
