The forecast for Sunday at Watkins Glen have been something of a moving target. This is due to the interaction of high pressure to the east and low pressure to the west. The trend over the past few days is for the low pressure to the west to move more slowly east, and for the high pressure to the east to become stronger and more dominant. That is why I have removed the chance of rain from Sunday's forecast. With the stronger high pressure system will come more stable conditions, more sunshine, and hotter temperatures.
