May 18: Tornado Watch #306

This watch is in effect for Central Oklahoma until 11 pm CDT.
DISCUSSION

Tornadoes, Hail to 3 inches in diameter, and damaging wind gusts upwards of 70 mph are possible.
In the next hour, isolated thunderstorm development is expected along a dryline. The area is moderately unstable and weakly capped at this time. Deep Layer shear will strengthen as a 50kt mid level jet stream moves into the area. Low level shear and vertical wind profiles will become quite conductive for supercells at this time. The primary hazard is large hail, but tornadoes are possible.
