What is ice fog?

Meteorologist Brett Collar breaks down a weather phenomena called Ice

Here in the Miami Valley we see all kinds of weather phenomena, including freezing fog and ice fog. While the two have similar dynamics, they do vary a bit.

Fog that turns to ice upon contact with a solid surface that has a temperature of 32 degrees Fahrenheit or less is known as freezing fog. This often occurs on elevated surfaces such as trees, power lines, bridges and overpasses. 

Ice fog is fog that freezes mid-air, simply because temperatures are so cold. The fog is not able to live long enough as water vapor and touch a solid surface before it crystallizes. 

Ice fog is not something that is often seen, and it only occurs while conditions are very cold and winds are light. The ice fog is noticed as a shimmering fog, often times referred to as frost flakes.

Fall colors nearing peak across Miami Valley

Published: Thursday, October 19, 2017 @ 6:07 AM

Meteorologist Kirstie Zontini talks about our color update from ODNR and forecast heading into the weekend.

Most of the Miami Valley is seeing peak or near peak fall color, according to the latest report from the Ohio Department of Natural Resources.

The reds, oranges and yellows might not be as bright as they were in the past because of the mild start to the month. The cool nights and sunny days this week might help a few slow changing trees to really pop. 

Sycamore State Park and Indian Lake State Park are seeing peak fall color.

>> Warming trend continues, lower temps arrive next week

The third week of October is typically when the Miami Valley sees the best colors emerge, and true color should show into next week.

Heavy rain or wind can take the leaves off the trees quickly this time of year, but weather this weekend is expected to be mild.

The rest of this week looks sunny and dry with highs in the low to middle 70s.

Orionid meteor shower peaks this week

Published: Wednesday, October 18, 2017 @ 5:53 AM

Meteorologist Kirstie Zontini talks about where and where to look for the shower.

After finding Venus and Mars early in the week, another special treat awaits you in the early morning sky heading into the weekend! 

The Orionid meteor shower will be peaking Friday night through Saturday morning. Debris from Haley's comet will hit the Earth's atmosphere, creating the show.

The Orionid shower gets its name because the meteors look like they are coming  from the constellation Orion. This year, 10 to 30 meteors per hour are possible. 

Skies will be dark all night because the moon will set early Friday evening, allowing for a good show. The best chance to see the most meteors may be from 2 a.m. until sunrise.
