 | About This Shoot | Date: 25 June 2012 | Location: Southeastern Alberta & Southwestern Saskatchewan from Oyen, AB to Kindersley, SK | Shoot Type: Storm Chase | | Synopsis:
Evan Bookbinder and I intercepted the first storm near Oyen, AB. After refueling at the highway intersection just north of town, we continued east to get back out ahead of it. Once we did, we photographed shelf cloud structure along the way to the Alberta-Saskatchewan border near the town of Alsask. Once we reached Kindersley, we made the decision to let the storm roll by us and photograph the backside of the storm. This turned out to be a good decision, as we observed and photographed an amazing backsheared cumulonimubus to the southeast in brilliant hues of orange, gold, and eventually magenta. Occasional lightning segments up in the anvil near storm summit were also photographed. The color was simply amazing and will be a moment we will never forget, being our first ever trip to Canada! |

CHASE UPDATE 6:45 PM MDT | | We crossed the Sask./Alberta border on Trans. CanadaHighway 1 and notice
d the winds had shifted from east to southwest, indicating a sfc low had de
veloped off to our north. Based on this,and the look of the cloud field,
we took Highway 41 north out of Medicine Hat, AB and watced Cu become tower
s and then several huge Cb in a matter of minutes. Currently racing toward
Oyen to intercept what, from the distance, looks to be a raging supercell.
Current temp 86F with a dewpoint of 67F. Pretty amazing for the interior of
eastern Alberta. With the lead wave aloft just now coming in from the sout
hwest, we are very hopefully about this intercept in the next 45 minutes. B

6/25 2 PM MDT Chase Update - Canadian Bound | | After a 30 minute chit chat with the Wilson Creek, SK border officers about
the ins and outs of photography, we finally did it! CANADA!!! First time f
or the both of us and we are very excited. We are headed to Maple Creek (ar
rival time about 3:30 PM) for analysis and targeting.A northwest moving
gravity wave (possibly generated by an early moning supercell), has ignited
an arc of elevated convection along the SK/AB border between Cavedish and
Kindersley, and the models actually had this early activity. The real show
should commence much later this afterno/evening as a strong shortwave troug
h lifts from Idaho across theCanadian border. High temperatures in the l
ow to perhaps mid 80s (sorry, we are staying with US units) and unseasonabl
y moist dewpoints in the mid 60s should yield a very unstable airmass with
3000-3500 J/kg of MLCAPE. Strong convergence along the western edge of the
low level easterlies, coupled with mid level height falls and increasingly
favorable shear profiles should yield an environment primed for scattered s
upercells along the NW edge of the cap. Activity may initiate in SE AB or S
W SK, with a northeast storm motion. We should have ample daylight to 11 PM
. More to come later. BOOKBINDER/UMSCHEID
