Discussion...
a cold front located across southwest Kansas and the Oklahoma
Panhandle will approach northwest Oklahoma this evening. Convective
allowing models indicate that isolated thunderstorms will be
possible. Effective bulk shear is forecast to only be 15-20
knots...so expect any storm organization to be limited. Steep low-
level lapse rates and downdraft cape over 1800 j/kg indicate that
gusty winds will be the primary threat with any storms that do
develop.

After collaboration with surrounding offices...opted to issue a
heat advisory for southeast Oklahoma on Wednesday. Expect heat
index values to be close to or near 105f.

The front will continue to slowly drift southward into Oklahoma
and will be a focus for isolated thunderstorms over the next few
days. Expect the middle-level ridge also to retrograde to the west.
The combination of additional cloud cover and northerly flow
aloft will cool temperatures down slightly over the next few days.

By early next week...expect temperatures to warm back up into
the middle to upper 90s with a decreased chance of rain. Another
cold front may approach the area by mid-week.
