Foggy morning, be careful driving to the polls

The National Weather Service is alerting to the presence of fog this morning, mostly in the interior areas of South Florida, but it could touch the parts of the coast until the sun rises.

Visibility could be reduced to under a half mile in some areas and drivers should be prepared for sudden fluctuations in visibility. The use of low beams is recommended.

Once the fog burns off, it should be another warm, dry day in Palm Beach County.

Temperatures are expected to hit 87 degrees today, which is eight degrees above normal for this time of year. Rain isn’t expected.

Fog happens when the temperature lowers to the dew point temperature and when winds are low.

A high pressure system is causing the abnormally warm temperatures this week.

High-pressure systems move like hands on a clock, bringing a westerly flow to the winds today and keeping air in a sinking pattern that without additional disturbances is known for clearer skies and fair weather.

Monday’s high temperature reached 86 degrees despite a faithful sea breeze that picked up in the afternoon and will likely reappear today. Unlike last week, the threat of rip currents is low with the westerly winds.

“We’re almost like in a summer atmosphere,” said Arlena Moses, a meteorologist with the National Weather Service in Miami. “We’re nearing the spring equinox and the sun is getting a little stronger.”
