.REGIONAL WEATHER DISCUSSION…
AREAS OF FOG WILL CONTINUE TO DISSIPATE EARLY THIS AFTERNOON. SOME
PATCHES OF DENSE FOG MAY STILL PERSIST THROUGH 1 PM ACROSS PARTS OF
CENTRAL AND WESTERN OKLAHOMA. DRIVERS STILL NEED TO BE CAUTIOUS AS
VISIBILITY COULD CHANGE QUICKLY. VISIBILITIES WILL CONTINUE TO
IMPROVE THROUGH THE EARLY AFTERNOON HOURS.
MEANWHILE… TEMPERATURES CONTINUE TO WARM ACROSS OKLAHOMA AND
WESTERN NORTH TEXAS… WITH TEMPERATURES ABOVE FREEZING ACROSS THE
AREA. TEMPERATURES ARE EXPECTED TO WARM INTO THE 40S ACROSS PARTS OF
NORTHERN OKLAHOMA… TO THE 50S AND 60S ALONG THE RED RIVER.
A look at the formation of freezing fog from Gary McManus of the Oklahoma Climatological Survey
A look at the development of the fog, freezing fog from Gary McManus, Oklahoma Climatological Survey
1. Light winds prevent any of that heat radiating to space to mix back down towards the surface, and the surface is allowed to cool quite effectively.
Light winds are a key component in the formation of radiation fog (and also keeping it around).
2. The air temperature cools to its condensation point (or dewpoint).
3. The Relative Humidity where the air temperature has reached its dewpoint will be 100 percent.
4. Now for the final ingredient … temperatures at or below 32 degrees. If the air is at the freezing point or below, the fog that does form will freeze on exposed surfaces (such as roads), and a full-fledged freezing fog event is born.
Low-lying areas can be colder than the surrounding terrain as that colder and more dense air sinks to the lowest available point, so even an above normal reading on the map can be misleading.
As the sun climbs higher in the sky and starts to warm things up, the air will start to mix a bit and the temperature will rise above the condensation point.
At that point, the fog will start to “burn off” as the water droplets evaporate back into the air.
