DISCUSSION...
It will be hot and humid across the region today, with heat index
values ranging from 100 to 104 degrees across northeast Oklahoma
this afternoon. Gusty southerly winds will also be common,
particularly north of I-44 this afternoon ahead of an approaching
cold front. Aforementioned cold front will approach northeast
Oklahoma late tonight, with the chance for thunderstorms
increasing after midnight along the Oklahoma/Kansas border and
spread southeast.

FRIDAY AND SATURDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Showers and thunderstorms will develop along and ahead of a cold
front early Monday morning and spread southeast throughout the
day. Greater instability across southeast Oklahoma and west
central Arkansas could support a few strong to severe storms along
the leading edge, with damaging wind gusts the primary concern.
Locally heavy rainfall will also be possible, with rainfall
amounts around a half inch to locally over one and one half
inches in some locations. Precipitation will end from north to
south Monday evening through early Tuesday morning.

Cooler and dry conditions are forecast behind the front on Tuesday
and Wednesday, before the heat returns by the end of the week.
Another system approaches the area next weekend, with
thunderstorm chances increasing beginning Friday and especially on
Saturday as another cold front approaches the region.
