The models are showing a frontal passage on Saturday or Sunday. How it affects competitors depends on timing. The latest run has the front passing sometime in the evening hours on Saturday.
The 0600 GMT GFS model run shows the following between Ft Desoto and Sanibel:
0100 Saturday - Increasing clouds. Winds SE 6-9 knots. Temps low 60s.
1300 Saturday - Showers. Winds WNW 9-12 knots. Temps mid to high 60s.
Could be a t-storm in between 1pm Saturday and 1 am Sunday.
0100 Sunday - Showers ended, clearing. Winds NNE 18-23 knots.
1300 Sunday - Clear. Winds NE 12-18 knots.
0100 Monday - Winds ENE 15-23 knots. The further south you are, the higher winds you will see.
When the 1200 GMT model run is posted I think we'll start to see 3 hour intervals for Saturday instead of the 12 hour ones I show above.
