Severe storms possible Saturday

An upper level high pressure ridge over Oklahoma will be shifting eastward by Saturday morning as a seasonably strong trough of low pressure approaches from the Western U.S.  There are indications that a lead short wave trough will be ejecting out of the long wave trough across the Southern and Central High Plains during the afternoon.  Rapidly lowering surface pressures will occur during the morning/afternoon as a low organizes near the southwest corner of Kansas.  An inverted trough of low pressure will extend northward from the surface low, and a dryline will extend southeastward from the low to far W Oklahoma.  In the warm sector ahead of the dryline, the atmosphere will be very moist and highly unstable.

As lifting associated with the lead short wave trough begins to spread across the High Plains, thunderstorms are expected to form during the early afternoon near and north of the surface low.  A capping layer will likely delay thunderstorm development along the dryline until mid to late afternoon.  However, increasing lift from the passing short wave, convergence along the dryline, and convection associated with afternoon heating is expected to overcome the cap, allowing thunderstorms to form.  Coverage of storms is not expected to be that great.  In fact, only a few severe storms may form in Oklahoma.  However, deep layer shear and strong instability will allow for any storms that do form to become supercell in nature producing all facets of severe weather including tornadoes.

The most dangerous storms are expected to occur over NW Oklahoma and points northward into Kansas.  This does not mean that a dangerous storm isn’t possible over W Oklahoma.  People across the western part of the state should review safety rules and be prepared to act quickly should warnings be issued for their area.
