Chase Trip Day 2 - June 17. Target: Eastern Colorado downwind of the Palmer Divide for early-mid evening high based supercell potential.
Day 2 target I will first drive out to Lamar for lunch and then
re-evaluate from there. More than likely I will drive northeast
toward Limon for the first storms coming off the Palmer Divide. CAPE
will be marginal at best for severe weather/supercells with 800 to
1200 J/kg expected in marginal moisture of mid 40s to near 50
dewpoint. The deep layer shear is great, however, and the early runs
of the HRRR model depicts supercell looking simulated composite
reflectivity "blobs" in east-central Colorado later this afternoon.
So there is some hope.

Outlook: Day 3 (Saturday) will be in the same general area, so
wherever I end up tonight, I will probably lodge near there for the
night (Burlington or Goodland?) instead of driving back to Dodge only
to go right back out there the next day. After Saturday's chase, I
will drive back to Dodge City to pick up Jay Antle who will drive to
my house late Saturday night or early Sunday morning. Sunday and
Monday look like definite chase days as a nice trough approaches the
plains. Tuesday could be another chase day farther south along the
trailing front in northwest Texas/southern Oklahoma or it could be the
beginning of a nice long drive to the northern High Plains (Montana?)
to get ready for the next Pacific jet to impact the northwest yielding
chase opportunities way up northwest by Thursday of next week. This
is still speculative, though, with a lot to potentially change (and it
probably will).
