DISCUSSION
FIRE WEATHER CONCERNS CONTINUE TO BE LIMITED AS MOISTURE

INCREASING RAIN CHANCES. SHOWERS AND THUNDERSTORMS WILL BECOME

7 DAYS FORECAST RAINFALL TOTALS VARY FROM 4 TO 7 INCHES ACROSS
NORTHWESTERN AREAS TO LESS THAN AN INCH FOR EXTREME SOUTHEAST
LOUISIANA AND MUCH OF THE MISSISSIPPI COAST. FOR MOST OF THE

QUESTIONS
WHAT IS THE CHANCE FOR DENSE FOG POST IGNITION AND WILL WE SEE ANY
CHANCE OF A SEA-BREEZE SET UP DURING IGNITIONS?
CAN'T RULE OUT PATCHY AREAS OF FOG, HOWEVER, WILL BE FULLY
DEPENDENT ON IF THE AREA SEES RAIN TODAY. IF SO, CHANCES FOR
PATCHY FOG WILL BE HIGHER. BUT REGARDLESS, NOT ANTICIPATING
WIDESPREAD DENSE FOG CONCERNS.
DOESN'T APPEAR TO BE A WELL-DEFINED SEABREEZE TODAY THANKS TO
