The short range models (HRRR and LAMPS) show a lower probability of thunderstorms today compared to  Friday.

Over the past week, the NAM lifted index and vertical velocity parameters have been highly correlated with thunderstorm development.

The NAM model shows positive vertical velocities and very unstable lifted indexes for much of the day, all parameters  conducive to thunderstorm development.  These parameters are more conducive  to thunderstorms than yesterday.   The NAM cranks out some precip during the evening hours, after 8 PM.

So, if we go with the short range models, look for scattered thunderstorms between 5 and 7 PM with a probability of only 35%.

If we go with the NAM parameters, look for scattered thunderstorms possible anytime late morning through  afternoon and especially late evening.

Trying to nail down a specific predictive parameter has been a challenge with this air mass.
