Area Forecast Discussion
National Weather Service Tulsa OK
610 PM CDT Mon Jul 24 2017

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
VFR conditions will prevail through the period, with the
exception of fog potential across northwest Arkansas. Fog is not
expected to be quite as prevalent as last night and thus only
forecasting reduction to MVFR visibility at this time. Isolated
thunderstorms in vicinity of FYV will dissipate within an hour or
two of issuance time.

.PREV DISCUSSION... /Issued 306 PM CDT Mon Jul 24 2017/

DISCUSSION...
Isolated showers/thunderstorms will be possible this afternoon
across far southeast Oklahoma and northwest Arkansas, primarily
in the higher terrain areas. Any storms will quickly dissipate
this evening with loss of surface heating.

Heat index values back above 100 degrees this afternoon across
portions of eastern Oklahoma. As upper high builds back into the
region expect much of eastern Oklahoma and west-central Arkansas
to have indices in the 103-107 degree range Tuesday afternoon.
High temperatures will be lower across southeast Oklahoma where
rain occurred yesterday, however this will be offset with higher
dewpoints. A heat advisory will be issued for aforementioned area
and will likely need to be extended through Wednesday with the
potential for additional counties.

Upper high will begin to retrograde westward Thursday into Friday
as stronger upper wave moves across the northeast states.
Precipitation chances will begin to increase Thursday into Friday
as cold front slowly pushes south through the area.

Finally a break from the heat expected this weekend behind cold
front. Much drier air-mass will remain in place into the early
part of next week as another upper low dives south towards the
Gulf Coast states. This will keep surface high pressure in place
across much of the central/eastern CONUS with light northeast
winds and dry/mild conditions.
