Area Forecast Discussion
National Weather Service Norman OK
1049 PM CDT Sat May 15 2021

...New AVIATION...

.SHORT TERM...
(This evening through Sunday)
Issued at 205 PM CDT Sat May 15 2021

A general moistening of the lower layers will continue through the
weekend. Weak westerly flow aloft will have embedded in it a weak
wave that will pass over Oklahoma tonight and early Sunday.
Sufficient buoyancy and lift will be present for showers and
thunderstorms from late evening into Sunday. Additionally,
thunderstorms are expected to form along a dry line near the NM-TX
border this afternoon and move east through the evening. This may
expand into a larger area of rain/thunderstorms that will enter
Oklahoma from the west overnight. Sufficient lift and instability
is expected with the upper wave as it passes east that rain and
thunderstorms are expected into Sunday afternoon over central and
eastern Oklahoma.

&&

.LONG TERM...
(Sunday night through next Friday)
Issued at 321 PM CDT Sat May 15 2021

Renewed convective development is expected to our west Sunday
afternoon and is likely to move into western OK during the
evening. Models show moderate instability along with 30-35 knots
of bulk shear to help maintain storms into western portions of the
area, with instability dropping off substantially across central
OK. It is likely that storms may try to grow upscale into an MCS
across western OK and then weaken as they move eastward into
central OK overnight.

The upper low to our west will continue moving eastward on Monday,
with most of the model guidance showing a shortwave rounding the
base of the trough into west Texas by Monday afternoon. Moisture
recovery behind Sunday night's convection is a bit uncertain as some
models show deeper moisture and better instability getting shunted
well south of our area Monday morning. Assuming we can get
sufficient airmass recovery, storms will likely initiate along the
dryline late Monday afternoon across the TX panhandle and spread
eastward into western OK and western north TX into the evening.
The mid to upper flow is not all that strong but should be
sufficient for supercells with initial discrete development, with
an accompanying risk for large hail, damaging winds, and perhaps a
tornado or two. Upscale growth into another MCS is possible by
later Monday evening which would then move across much of the rest
of the area Monday night, bringing with it the risk for damaging
wind gusts.

Depending on how convection evolves Monday night, Tuesday may end up
with a lull in convection for central and northern OK if the airmass
is sufficiently worked over. Storms may linger into Tuesday
afternoon and evening along residual outflow across southern and
southeastern portions of the area as the upper trough remains to our
west. The flood threat will need to be watched for these areas as
several rounds of convection are possible Tuesday into Tuesday
night.

Occasional rain chances continue Wednesday into next weekend as
upper troughing reloads to our west and upper ridging builds over
the eastern US. This should keep moisture flowing northward with
embedded shortwave impulses likely leading to periods of enhanced
convection. Occasional severe weather is possible but no real signal
exists in the guidance at this range to narrow down specific days
with higher chances. Flooding will also be a concern over the next
week as multiple rounds of heavy rainfall will lead to several
inches of rain, with localized amounts of greater than 5"
possible.

.AVIATION...
(06Z TAFS)
Issued at 1044 PM CDT Sat May 15 2021

Evolving MVFR cigs and vis restrictions still appear likely toward
and after about 10-12Z, but confidence is not as high as it was
before the 00Z guidance arrived. Models have delayed and decreased
intensity/coverage of precipitation after 12Z, but given
increasingly moist lower levels, we will keep the lower cigs going
much of the day tomorrow, although there may be period of clearing
during the afternoon/early evening. Confidence low on TSRA
tomorrow evening so will not include this cycle.

831 PM CDT Sat May 15 2021

This hazardous weather outlook is for portions of northern...
western...central...and southern Oklahoma...and western north
Texas.

.DAY ONE...Through Tonight...

.Thunderstorms...
Scattered thunderstorms are still expected. The strongest storms
may briefly produce hail around one-inch in diameter and winds up
to 60 mph, but a majority of storms should stay below severe
levels. Due to slow movement, high rain totals and minor flooding
will be possible.

While an isolated storm is possible over the body of Oklahoma
this evening, the highest chances for storms will be associated
storms over the panhandles this evening, which will approach
western Oklahoma after midnight. These storms will weaken before
moving into Oklahoma and western north Texas.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

.Thunderstorms...
Thunderstorm chances will continue Sunday thru Friday. Severe
thunderstorms will be possible Sunday evening west of a line from
Wichita Falls, to Lawton, to Seiling, to Freedom. Hail up to the
size of golf balls and wind gusts up to 70 mph will be the main
threats. Severe thunderstorm chances will return Monday afternoon
into Monday night to the western half of Oklahoma and western
north Texas. Very large hail, damaging winds, and perhaps
tornadoes will be possible by Monday. Strong to severe
thunderstorms will continue into Tuesday and Wednesday.

.Heavy Rainfall...
At least localized flooding will be possible area wide Sunday
thru Thursday. Many locations across the region could receive
over 3 inches of total rainfall by the end of next week.
