Potential tornado event in South Dakota

Conditions appear to be coming together for a mini tornado outbreak in eastern South Dakota tomorrow (Saturday) afternoon and evening. Substantial instability, an unseasonably strong low-level jet, insane moisture, and a potent mid-level jet streak will set the stage for explosive supercell development after 4 pm in central to eastern SD. The presence of any outflow boundaries from overnight storms will also enhance the threat for tornadoes. I left Norman at 6 pm this evening for a target in eastern South Dakota, once again without Joel (who is very close to having his profile removed from this site due to lack of stormchasing passion). For those interested, the WRF forecast 0-1 and 0-3 km helicity, CAPE, CIN, and 500 mb wind for tomorrow afternoon/evening are displayed below. The 0-1 km helicity values of 150-200 are sufficient for large tornadoes, especially with the presence of outflow boundaries. Tomorrow could be the apocalypse.

Stay tuned to the StormWatch player (upper right) for videotaped updates on our progress throughout the chase.

Saskatchewan Update
Written by Reed Timmer

Today (Friday) has been an active day across parts of Saskatchewan as expected. Tornado warnings have been numerous across west-central SK with cold-core action, and across eastern Saskatchewan in the warm sector. The radar image below shows the supercell that has been tornado warned. It's unfortunate that I could not convince anyone to make the 27 hour drive, or we'd be driving through this tornado right now and rolling in a canola field.

Tornadoes possible tomorrow in Saskatchewan, Canada
Written by Reed Timmer

A textbook trough with embedded shortwave trough will traverse the Canadian Prairies on Friday, August 11, yielding favorable CAPE and shear for tornadic supercells over southeast Saskatchewan. Substantially directional and speed shear will prevail where the mid-level jet streak and low-level jet coincide. CAPE values of 3000 J/kg and greater will also develop by mid-late afternoon, setting the stage for potentially explosive supercell development. I (Reed) attempted to find someone to accompany me on the 27 hour drive to my target area in Saskatchewan, but failed to do so. I am very tempted to fly solo on this chase, but it could be physically impossible to endure a 27 hour drive followed by a 4-6 hour stormchase without sleep. Updates will follow as this event unfolds, and if a tornado outbreak occurs, Joel's profile may be deleted from this site, as his stormchasing range is in question!

As seen above, a 50 knot mid-level jet streak will be superimposed on a 30-40 knot low-level jet and 3000+ J/kg CAPE axis. I should have left Wednesday.

An incredible supercell has been churning across the high plains of Alberta today (Thursday) for the last few hours. Definitely a sign of things to come tomorrow. It appears that additional supercells may form along a line south of this monster as well. This storm also has split twice, confirming its supercell characteristics, and likely has baseball or larger hailstones.
