THERE WILL ALSO BE A POSSIBLE THUNDERSTORM THIS AFTERNOON. THE
PRESSURE GRADIENT IS QUITE WEAK NEAR THIS BOUNDARY AND THE LOW
LEVEL FLOW BEHIND THE FRONT AND NEAR THE FIRE SITE WILL BE VERY
WEAK AT LESS THAN 10 MPH. THIS WILL RESULT IN THE DISPERSION TO
REMAIN POOR THIS MORNING AND ONLY BECOMING POOR TO FAIR BY LATE

REGION WILL KEEP RELATIVE HUMIDITIES WELL ABOVE CRITICAL LEVELS.
