DISCUSSION
A RIDGE OF HIGH PRESSURE WILL BE BUILDING OVER THE
REGION LATER TODAY THROUGH MONDAY...BEFORE SHIFTING TO THE EAST ON
TUESDAY. UNDER THE RIDGE ON MONDAY THE TRANSPORT WINDS WILL BE
LIGHT MAKING FOR A RELATIVELY POOR CLEARING INDEX. WITH THE RIDGE
SHIFTING EASTWARD ON TUESDAY THE TRANSPORT WINDS WILL INCREASE
FROM THE SOUTHWEST BUT ALTHOUGH THE HORIZONTAL DISPERSION WILL BE
GOOD THERE IS A HINT THAT THE VERTICAL MIXING WILL BE STYMIED BY A
WEAK STABLE LAYER AROUND 12000 FT MSL. THEREFORE...THE BEST DAY
WILL BE WEDNESDAY WHEN THERE WILL BE GOOD TRANSPORT WINDS AND
EXCELLENT MIXING.
