Tracking Predictions

6 July 2018

Same general track, except a couple of miles north. Surface weather indicated minimal chance of rain in the morning, with light winds out of the E-SE.  Chase and recovery should be warm but tolerable.

July 6 flight predictions

 

5 July 2018

The track continues to be in the same general area, south of US-50 near Sylvia.  Weather forcast for Saturday is calling for sunny skies, and warm.

July 5 flight prediction.

3 July 2018

 The surface level winds appear to have shifted out of the east, but otherwise the flight track is largely unchanged.

Predictions for July 3.

 

1 July 2018

 

Predictions for July 1.

 

28 June 2018

Similar track as the initial.  Today is landing slightly east of Pratt.

June 28 flight predictions

 

27 June 2018

The initial flight prediciton shows a southwest track, landing just north of Pratt.  The long range surface weather forcast calls for hot with sunny skies.

June 27 flight predictions.
