In addition to storms over the great lakes, the WRF is forecasting a 40-50knt speed max moving through southern Montana and northern Wyoming. A weak sfc low develops in the afternoon to help back sfc winds from the SE. SSE to S 850mb winds at 20-25knts will help enhance lowlevel shear. Moisture will be in place with low 60's Tds all the way to the I-25 corridor and upper 50's in southeast Montana. This will give CAPE values of 1500 J/Kg in Montana and southern WY/northern CO values in the 2500 J/Kg range. LCL heights will be workable with T-Td spreads of roughly 20-25 degrees. We should have supercells develop early with a couple of tornadoes, then transitioning to MCS's after the cold pools rush out. I will be going out targeting most likely somewhere in eastern WY.
