DISCUSSION
DOMINANT HIGH PRESSURE WILL RESULT IN STABLE
CONDITIONS CONTINUING, RESULTING IN LOW CLEARING INDICES DESPITE
BREEZY WESTERLY WINDS THIS AFTERNOON. GRAZING MOISTURE COULD
PRODUCE ISOLATED SHOWERS THROUGH THIS EVENING, THOUGH ANY RAINFALL
AMOUNTS SHOULD BE RELATIVELY LOW, LESS THAN 0.10"...WITH A LOW
(10%) CHANCE OF REACHING UP TO 0.25". AS HIGH PRESSURE SLOWLY
NUDGES OVERHEAD THROUGH THE WEEK, EXPECT LIGHTER WINDS, WARMING
TEMPERATURES, AND STILL VERY STABLE CONDITIONS. THERE COULD BE A
PASSING WAVE NEXT TUESDAY THAT RESULTS IN POTENTIALLY BETTER
MIXING, THOUGH THIS IS STILL PRETTY FAR OUT IN THE FORECAST
PERIOD SO THAT MAY CHANGE.
