New UPDATE, AVIATION, MARINE
UPDATE
The main weather concern today has been the haze caused by smoke from Canadian wildfires reducing visibilities at times to less than 2 miles in some spots. Regional METAR observations and sky cameras have been showing an improvement in visibilities across the area during the last few hours, and HRRR Near-Surface Smoke model runs are showing that the smoke should continue to improve through Wednesday morning as the ridge to the north shifts to the east. However, those same HRRR runs are showing another mass of smoke over the western Atlantic advecting southwest to Florida, so additional rounds of haze could be a threat through the next few days.
The forecast looks on track, with limited rain chances overnight, and no significant forecast changes are planned for the evening update.
AVIATION
(00Z TAFS)
Hazy conditions have been improving over the last few hours, although some MVFR visibilities are lingering over southwest Florida, and some brief periods of MVFR conditions cannot be ruled out overnight further to the north as well. Haze will continue to be a threat through Wednesday, although changes in the wind pattern are giving some hope that vis restrictions will not be as bad on Wednesday. Otherwise, mainly rain free conditions are expected through the next 24 hours, with just a slight chance of showers in the forecast over the interior Wednesday afternoon.
