...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are unlikely through tonight.

...Upper OH Valley into western NY this evening...
A midlevel shortwave trough over the upper MS Valley this morning
will progress east-southeastward to NY/PA and the Mid-Atlantic by
the end of the period. Ascent preceding the midlevel trough and an
associated surface cold front could support some shallow convective
showers late this afternoon/evening from northeast OH to western NY.
However, marginal low-level moisture and minimal buoyancy suggest
that thunderstorms are unlikely.

...Northern AR to central OK this afternoon...
Boundary-layer dewpoints near 60 F and surface heating will drive
surface-based buoyancy this afternoon along a slow-moving front from
northern AR into central OK. Thermodynamic profiles suggest some
potential for deep convection, but forcing for ascent will remain
shallow/weak at best. Overall, thunderstorm potential appears too
limited for an outlook area.
