...HIGH AFTERNOON DISPERSION TODAY AND THURSDAY...

.DISCUSSION...Hot and rain-free conditions are expected under
influence of high pressure today. Southwesterly winds prevail
today and increase around 1400 as the Gulf sea breeze arrives.
Patchy fog is a bit iffy given the wind (as mentioned), more
likely to be low stratus cloud cover. However, for sheltered areas
stratus could surface as patchy fog but unlikely to be significant
or dense Thursday morning. Similar weather pattern is expected
Thursday with dispersions becoming High by the afternoon.

Confidence is low but we are monitoring a potential complex of
thunderstorms capable of strong outflow winds Thursday evening.
This cluster of storms wouldn`t likely reach the RX location
until the evening (7-9 pm) if it actually materializes.

Have a safe burn!
