IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
EXPECTING MILDER AND DRY DAY ON TUESDAY.
TRANSPORT WINDS WILL BE BETTER ON TUESDAY DUE TO HIGH PRESSURE SHIFTING
EAST OF THE AREA WITH BOUNDARY LAYER FLOW SHIFTING TO THE SSW. GIVEN THE
GOOD TRANSPORT WINDS AND MIXING HEIGHTS, DISPERSION SHOULD
IMPROVE TO THE EXCELLENT RANGE BY THE AFTERNOON. AROUND IGNITION TIME,
TRANSPORT WINDS MAY BE MORE SOUTH TO NORTH AND SMOKE COULD IMPACT STATE
ROUTE 1389. HOWEVER, WINDS SHOULD SHIFT MORE SOUTHWESTERLY TO NORTHEASTERLY
THROUGH THE DAY ALONG WITH IMPROVING DISPERSION, SO SMOKE WOULD LESS LIKELY
IMPACT LATER IN THE DAY.
