Area Forecast Discussion
National Weather Service Norman OK
1156 PM CDT SUN JUL 3 2016
.AVIATION...
THUNDERSTORMS OVER SOUTHEAST OKLAHOMA WILL CONTINUE
TO MOVE EAST AND SOUTH OVERNIGHT. LOW CLOUDS WITH
MAINLY MFVR CEILINGS MAY FORM BY 9-10Z ESPECIALLY
ACROSS NORTH CENTRAL AND CENTRAL OKLAHOMA. SOME
LIGHT FOG IS ALSO POSSIBLE. SOUTH WINDS WILL INCREASE
MONDAY AND LOW CLOUDS WILL DECREASE DURING THE MID
TO LATE MORNING.
&&
.PREV DISCUSSION... /issued 633 PM CDT SUN JUL 3 2016/
DISCUSSION...
The 00Z aviation discussion follows....
AVIATION...
Strong/severe thunderstorms have formed along a weak frontal
system from near KOUN northeast to KTUL and beyond. Additional
storms have begun to form along a surface trough from KOUN
southwest to KSPS and KABI. This assembly of storms is expected to
move slowly toward the southeast (while individual storms mostly
move toward the east).
A layer of stratus is forecast to move south from Kansas into
central and northern Okalhoma, bringing mainly MVFR ceilings,
although a few hours of IFR could happen, especially at KPNC.
There is also a chance that thunderstorms, now over the High
Plains, may affect KSPS-KHBR toward sunrise, but the chance is
rather low.
PREV DISCUSSION... /issued 337 PM CDT SUN JUL 3 2016/
DISCUSSION...
Severe storms will be possible across central and southern parts
of CWA through at least mid-evening. Along with a primary impact
potential for damaging wind gusts with strongest storms, there
will be a heavy rain and flash flood threat especially this
evening across southeast portions of Oklahoma. Coverage and high
flash flood guidance values, covering an area that has not see
much rain recently, will preclude flood watch.
Convective potential will remain tomorrow mainly across the Red
River Valley near stalled frontal boundary. Again, damaging wind
gusts and heavy rain will be the primary concerns. Each day of the
coming week will see a chance for at least isolated storm activity
as models slower and less aggressive with building ridge. Chances
increase a bit late in the week with a potential week front making
its way south from the Central Plains.
Heat will be a concern this week, with several locations seeing
near and above 105 heat index values this afternoon. No
significant cooling expected for tomorrow and outside of
northwest and west-central Oklahoma, dewpoints are expected to be
as high or higher next few days. This has resulted in a Heat
Advisory for all but far northern and western Oklahoma through
Tuesday. This advisory may be expanded in space/time Tuesday into
mid-week as confidence increases on hotter temperatures spreading
farther north. Drier air over far western Oklahoma will likely
keep those locations with heat indices closer to dry bulb temps.
