.DISCUSSION...
Plentiful sunshine expected today. A morning inversion is expected
to lift through the morning, likely breaking around 11 AM. Mixing
conditions increase to excellent thereafter. Southwest winds this
morning may become closer to due westerly midday into the
afternoon for several hours. With sunshine and a well-mixed lower
atmosphere, RH may fall to around 35%.
A pretty typical cooling night tonight with an inversion
developing after sunset, but a low-level jet will result in
increasing wind speeds just above the inversion.
Wind direction will remain fairly constant into Friday from the
southwest. Warmer, but with a little more moisture in the air.
