.DISCUSSION...
HIGH PRESSURE OVERHEAD HAS CAUSED A SUBSIDENCE INVERSION TO FORM
AND WITH LIGHT WINDS...SMOKE DISPERSAL WILL BE POOR ON TUESDAY. ON
WEDNESDAY AN APPROACHING AREA OF LOW PRESSURE WILL BREAK DOWN THE
INVERSION AND ALLOW GOOD SMOKE DISPERSAL IN THE AFTERNOON THOUGH
WINDS WILL STILL BE RELATIVELY LIGHT. BY THURSDAY...THE LOW
PRESSURE WILL BECOME AN OPEN WAVE AS IT MOVES OVER THE AREA
BRINGING SOME ISOLATED SHOWERS...MAYBE A THUNDERSTORM...NEAR THE
BURN SITE. UNSETTLED WEATHER CONTINUES INTO FRIDAY WHICH LOOKS TO
BE THE BEST DAY FOR ANY PRECIPITATION OVER THE BURN SITE FROM
ABOUT NOON ONWARDS. SOME VERY ISOLATED SHOWERS ARE POSSIBLE
SATURDAY AND SUNDAY BUT SHOULD NOT AFFECT THE BURN SITE.
