Hail and Damaging Winds in Oklahoma, May 14, 2022

.SHORT TERM...
(This evening through Sunday)
Issued at 205 PM CDT Sat May 14 2022

Main forecast issue will be the potential development of
convection late this afternoon into this evening, and again
Sunday afternoon.

For this afternoon/evening, a cumulus field has developed in
western Kansas south in to the northeastern Texas panhandle and
northwestern Oklahoma with a few orphan anvils that have been shed
west of Dodge City. The models have differing opinions of what to
expect as far as storm development this evening, although the
trends in the convective allowing models have been toward less
convection, with the exception of the ii-res FV3 and hi-res NAM
which tend to be the most aggressive. Despite the trends in model
solutions, there is a continued reduction in mixed-layer CIN and
some low POPs still seem reasonable in the northwest for the
potential of isolated storm development. And any storms that
develop could be severe with sufficient instability over the area.
Expect any convection to be mostly diurnal, so do not thing the
probability is high enough to mention after 06Z. The GFS does show
a complex moving southeast, but it looks to be suffering from
convective feedback.

A cold front slides southeast tomorrow afternoon with
thunderstorms expected to develop along the front, initially in
southeast Kansas and northeast Oklahoma before developing
southwest along the front through the late afternoon and evening.
The question will be will the storms develop far enough southwest
along the front to affect the eastern portion of the forecast
area. The 30 percent POPs in the northeast from NBM seem
reasonable.

.LONG TERM...
(Sunday night through next Friday)
Issued at 124 PM CDT Sat May 14 2022

Showers/storms will remain possible in at least eastern parts of the
fa Sunday evening/night as a cold front continues to move across the
region. Models show showers/storms continuing to develop near/behind
the front from MO/AR into OK although there is some question as to
how far west the development will occur. Instability and shear will
be sufficient for a continued risk of strong to severe storms Sunday
evening/night as these storms move across the region with damaging
winds and hail the main concern.

Cooler air moving into the region behind the front Sunday night will
lead to cooler temperatures Monday with highs ranging from the low
80s E/NE portions of the fa to mid 90s in SW parts of the area.
After the brief "cool" down Monday, hot, above average temperatures
are expected the rest of next week.

Next week, models show generally zonal flow with weak perturbations
and/or shortwaves moving through the flow. Models do show a change
in the upper pattern towards the end of next week as an upper trough
begins to dig across the western U.S. leading towards WSW/SW flow
over the region towards the end of next week. With the different
perturbations/disturbances in the flow, there are some low chances
for showers/storms off and on next week for parts of the fa with
much of the area expected to remain dry. However, where/when these
showers/storms may occur will be somewhat dependent on the timing of
these disturbances although it looks like one of these could affect
the region Monday evening/night. A better chance for rain and over a
larger area could be late next week/next weekend as the previously
mentioned upper trough moves closer to and across the Plains
although a lot of time between now and then for this to change.

Some increased fire weather concerns could begin again Tuesday and
continue for at least part of next week across portions of western
OK and western north TX.

.AVIATION...
(00Z TAFS)
Issued at 602 PM CDT Sat May 14 2022

VFR conditions to continue.

A few isolated storms may move into northwest Oklahoma this
evening, but chances to impact WWR remain too low to mention in
TAF at this time. Elsewhere east/southeast winds will shift to the
south at most locales before shifting to the north/northeast as a
surface cold front slides south through the area Sunday. Speeds
will be around 10-12kts.
