Friday March 20 2020

Spring has officially begun and it will feel like it today, for one day.  Traffic is very low with the COVID19 State of Emergency, but there have been accidents in the low visibility.

This morning a Dense Fog Advisory is in place. This is the result of warm air trying to cool the cool moist air out of the region.  The fog should dissipate between 8 and 9 AM. As we warm to the mid 70s and approach 80ºF, there will be showers mixing in.

Dense Fog Advisory



Under .50 mile in the Advisory area, but quickly jumping to 10 miles where the warm air has arrived




Morning Surface Weather

Once this front moved through, we will warm up.  But cooler air on the way from the west will bring in showers during the afternoon. Temps will be much cooler this weekend.


How Warm?

This will depend on how much sun you see and the progress of the rain.  Here are three model temperature forecasts:
