Area Forecast Discussion
National Weather Service Norman OK

.DISCUSSION...
Isolated/scattered showers and storms will continue to develop the
rest of this afternoon and evening. Activity is more likely in the
areas north and south of a band of clouds associated with the area
of development across portions of the fa earlier today. These areas
have received more heating due to no/fewer clouds. Gusty winds,
small hail, and very heavy rain are the main concerns with the
storms. A few storms could even approach severe levels but
widespread severe weather is not expected.
Coverage of storms will likely decrease after sunset but isolated
showers/storms will remain possible overnight. Showers and
thunderstorms will remain possible into at least the middle part of
the week. However, the area where rain will be possible will slowly
shift to more northern/eastern parts of the fa by later this week as
the influence of the upper high begins to increase in portions of
the region. The rain is currently expected to remain north and east
of the fa late this week but this is dependent on how far east the
high pressure builds. If it doesn't build as far east as some of the
models show then low rain chances may continue on the periphery of
the fa late this week.
With the upper ridge building into the area, temperatures are
expected to increase with triple digit temperatures possible across
a good portion of the fa by late this week. The hotter temperatures
are expected to lead to increasing heat concerns over a larger
portion of the fa, especially later this week. The heat advisory in
south central and southeast OK will continue through late this
afternoon. A heat advisory may be needed again in SE parts of the fa
for Monday afternoon, forecast heat indices around 105, but since it
is marginal will hold off for now and let later shifts assess if one
is needed. However, heat advisories for a larger area may be needed
later this week.
