Pocatello Storms

We're currently monitoring conditions in eastern Idaho. Right now I'm using various applications to analyze and initialize current conditions. Currently AllSky is showing cape around 1000kj, and PWATS around .80 inches.



That PWAT value on the morning sounding just west of the area was close to .64". Seeing how moisture levels are lower to west I can interpolate that the moisture values are similar to what's show on allsky. The allsky 900-700mb also seems to pick up on the relatively moist area in the lower half of the atmosphere.



Looking downstream we're noticing a line of developing convection using the Day land cloud RGB. It's helpful to analyze just how high the tops of the storms are getting combined with cloud tops.
Zooming in closer I can examine the few storms that have popped up more closely. The RBG help the differentiate between the ambient cirrus clouds from the growing storms. That might not have been as easy to see using a typical visible view.



The AFA and Minimum flash area maximums are hinting at growing convection just downwind. That growth leads to me to anticipate further growth as these storms move into a more favorable environment in eastern Idaho.
