The NWS Sterling forecast for our area has a slight chance of storms Friday afternoon with better chances Friday night and Saturday. The GFS seems to want to speed up the oncoming system and associated cold front, pushing the front through here early Saturday morning but creating some decent chase parameters for late Friday afternoon and evening (see graphic above for instability). These parameters include both speed and directional shear plus dewpoints in the upper 60’s. If we can just convince the well-known “lee trough” to form east of the mountains on Friday afternoon that would provide a convective trigger to fire off storms ahead of the cold front itself. The countdown is underway.
