Moisture slowling returning to the forecast aboard southeast winds with dewpoints in the lower 60s, and middle 60s south south of the area. Fog has finally burnt lifted in the far southeast, while convection has developed near KCYS. Driver today will be a strong upper level wave as seen on H2OV channels coming into Wyoming sparking strong convection in western WY. All short term convective models hold off on convection til a strong cap weakens about 21z-22z and then quickly develop and move it east. Combination of wind and hail risks initially will turn to a potentially significant wind event over the about the east 1/3rd of the forecast area. 70 mph winds could be common by mid evening along the front of the line of storms. Tornado risk appears to be small but no non-existent as embedded supercells in the line may be problematic at times. Expect a severe weather watch late this afternoon with a high likelihood of convection between 4 and 10 pm...resulting in severe weather over much of the forecast. Things should calm down fairly quickly after dark.
