Area Forecast Discussion
National Weather Service Norman OK
1042 AM CDT Sat Jul 22 2017

.UPDATE...
Updated hourly temperatures through this evening.

&&

.DISCUSSION...
No significant changes were made to the forecast for this
afternoon. Hourly temperatures were updated based on short-term
models, which resulted in a slower cool down for this evening`s
temperatures (the overall temperature trend is consistent with
what was observed yesterday).

Some models indicate that remnant/dissipating convection across
Kansas and the Texas panhandle may affect parts of
northern/western Oklahoma late this evening; however the
probability appears low.

DISCUSSION...

AVIATION...
VFR conditions will continue with hot conditions and south wind
generally less than 12 knots.

PREV DISCUSSION... /issued 306 AM CDT Sat Jul 22 2017/

DISCUSSION...
Extreme heat and humidity will persist into Sunday, particularly
along and east of I-35 where heat index values will again approach
110. A weakness finally comes late this weekend to the northeast
quadrant of the strong upper high. This will be associated with a
trough moving through the upper Mississippi Valley and Great Lakes
regions. A weak front is expected to feebly drift into northern
Oklahoma Sunday night and bring a chance for rain and thunder. The
chance for rain/thunder will spread across the northern two-thirds
of Oklahoma Monday while the surface boundary languishes and still
weak influences from the upper trough exist. However, this period
will be short-lived as temperatures again soar to values similar
to those of the last several days for the second half of next
week. Little chance for rain to temper the heat will exist until
at least next weekend.
