DISCUSSION
WIDESPREAD CLOUD COVER IS EXPECTED TODAY AS WARM ADVECTION MOVES IN ALOFT.
WHILE THE WARM ADVECTION WILL LEAD TO SATURATION ALOFT, AN 8-10 KFT LAYER
OF DRY AIR WILL LIMIT ANY RAIN CHANCES. A FEW SPRINKLES CAN'T COMPLETELY BE
RULED OUT, BUT A GROUND WETTING (FIRE STOPPING) RAIN IS NOT EXPECTED. WINDS
WILL OSCILLATE BETWEEN NORTHEAST AND EAST (60 TO 90 DEGREES) THROUGH THE DAY,
GENERALLY MAINTAINING PEAK GUSTS TO 20 MPH THIS MORNING, WITH SOME EASING TO
10 TO 15 MPH GUSTS THIS AFTERNOON. WITH THE EAST TO NORTHEAST WINDS OFF OF
THE LAKE AND COOL HIGHS IN THE MID TO UPPER 50S, MIXING HEIGHTS WILL GENERALLY
RISE TO 3000 FT AROUND NOON AND QUICKLY DROP TO 2000 FEET LATER IN THE AFTERNOON.
EXPECTED MIXING HEIGHTS AND WINDS WILL LEAD TO PEAK SMOKE DISPERSAL AROUND
39000 KNOT-FT, BUT IT SHOULD BE NOTED THAT ANY LOWER WINDS/LOWER MIXING HEIGHTS
MAY DECREASE THE KNOT FEET CLOSER TO OPERATIONAL THRESHOLDS.
