....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Friday.

....Synopsis...

A positively tilted upper trough will encompass much of the western
half of the CONUS on Friday. Meanwhile, an upper ridge will persist
over the Gulf of Mexico toward the Mid-Atlantic coast. Between these
two features, moderate deep-layer southwesterly flow will persist
over parts of the Plains and the Midwest. At the surface, a cold
front will extend from WI southwestward into western/central OK and
northwest TX. This front will shift south and east through the
period as strong high pressure filters into the northern/central
Plains, extending from eastern OH toward northern AR and north TX by
Saturday morning. 60s F surface dewpoints will exist ahead of the
front, resulting in modest destabilization. A couple of strong
storms are possible given 20-30 kt effective shear magnitudes.
However, modest boundary-layer heating and generally weak low and
midlevel lapse rates will limit overall severe potential.
