Predict? I doubt it.

Factors that contribute to haze:

• Warm daytime temps that allow plants to emit various hydrocarbons. Notably 'Blue Ridge Mountains' More common over hardwood forests, less common over pine, lesser still over spruce, largely absent over grass. Probably reaches a peak between 80 and 90 F as thats when plant stomata are open widest.

• Humidity. Higher humidity will make condensation more likely.

• Dust. Fine dust itself is a light blocker, and also acts as condensation nuclei for water droplets.

• Fire. Even distant fire can add significant haze especially if weather conditions are mixing high altitude air down to the surface. A nearby fire can turn the sun off.

• Agricultural activity -- ploughing, harvesting -- increases dust in the air.

• Dry weather. Increases dust, increases fire risk

• Temperature inversions: Local dust/polution sources are trapped below the inversion layer.

• Low temps combined with high humidity -- ice fog.

Factors that reduce haze:

• Cold temperatures. Plants shut down.

• Wet ground. Dust sticks.

• Frozen ground. Less dust.

• Snow on ground. Even less dust.

• Strong winds, when otherwise no dust source. Tend to mix high altitude flows with surface air.

Local airports will report the visibility, and some stations will give forecasts of it. You may find that 'unlimited' is ok for pix but 'Visibility 5 miles' is not.
