The reach cast will pay dividends meaning accomplishing your mend in the air as opposed to on the water when crossing the current. Imagine painting a canvas starting at the upper right hand corner and brushing your stroke down to the bottom left corner with one sweep. This is a smooth one step cast rather than a forward stroke and then a rod tip movement upstream which defeats your purpose. Start your fly at the target then smoothly bring the tip of the rod upstream in one movement.
The weather forecast is calling for highs in the 40's and partly sunny. Some pools and runs are frozen depending on the section of river.
