A prominent warm spell through the east has broken some daily high temp records via EC.

An upcoming medium range pattern shuffle remains evident as of the latest indications. This looks to feature H5 ridging becoming oriented over the SW USA, extending towards the PAC NW and possibly into SW BC.

Meanwhile upper troughing will gradually carve into central Canada with the possibility of multiple waves of moisture riding along the boundary in a general SW-to-NE direction through the GL & east.
