Sat, 23 Jun 2012 20:22:28 -0500 7:15 PM MDT Chase Update - Target Storm | Things are changing quickly as the lead shortwave impulse has come across
the higher terrain of Montana in concert with peak heating, the return of
abundant low level moisture (55-60F dewpoints) and strong vertical shear.
Visually, one very impressive/isolated cell has developed a very crisp,
back-sheared anvil northwest of Great Falls. This storm is about 100 miles
NW of our current location, and a right moving supercell should afford a
slow eastward turn. With its slow movement we hope to be in place to
intercept before 9 PM. (This leaves us a good 2 hours of daylight). This
storm is quite impressive on radar for so early in its life cycle as well,
and appears well underway to acquiring supercell structure if not already.
Very excited! - Bookbinder
