.DISCUSSION...High pressure remains in place through most of the week
leading to dry stable conditions and light terrain driven winds
with downdrainage winds overnight and updrainage winds during the
day. Light transport winds aloft with an inverted thermal layer
extending above the surface will continue through Monday. A weak
dry shortwave will be moving by to the northeast on Tuesday that
will enhance the flow aloft and bring some cooling that will
weaken this thermal inversion enough to allowing for better
ventilation (clearing around 500-600). This clearing goes back
down by Wednesday, but then increases again later in the week
ahead of a more substantial trough late in the week.
