.DISCUSSION...
UPPER TROF WILL BE SHIFTING INTO THE MISSOURI VALLEY WHILE HIGH
PRESSURE EXPANDS ACROSS THE SOUTHWEST ON WEDNESDAY...LEAVING THE
CENTRAL ROCKIES UNDER MODERATELY FAST AND DRY NORTHWEST FLOW ALOFT.
THIS SHOULD LEAD TO MOSTLY SUNNY SKIES AND TEMPERATURES RISING INTO
THE MID 50S BY THE EARLY AFTERNOON HOURS. WINDS WILL BE TERRAIN
DRIVEN TO START THE DAY WITH SURFACE INVERSION IN PLACE. AS THE
MIXING DEEPENS WITH HEATING...WINDS SHOULD TURN TO THE WEST TO
NORTHWEST BY EARLY AFTERNOON. MIXING HEIGHTS LOOK TO BE HAMPERED
SOMEWHAT BY WARMING TEMPERATURES ALOFT CREATING A FAIRLY STRONG
INVERSION NEAR 5000 FT AGL...BUT THE GRADIENT LOOKS TIGHT ENOUGH
BELOW THIS UPPER INVERSION FOR DECENT TRANSPORT WINDS TO DEVELOP.
