Severe Thunderstorm Watch Number 375
NWS Storm Prediction Center Norman OK
530 AM CDT Fri Jun 6 2025
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Northwest Arkansas
Southwest Missouri
Eastern Oklahoma
* Effective this Friday morning from 530 AM until 1000 AM CDT.
* Primary threats include...
Scattered damaging winds likely with isolated significant gusts
to 75 mph possible
Scattered large hail events to 1.5 inches in diameter possible
A tornado or two possible
SUMMARY...A line of intense thunderstorms over central/eastern
Oklahoma will continue to track eastward for several more hours,
posing a risk of damaging wind gusts and some hail. A tornado or
two is also possible.
The severe thunderstorm watch area is approximately along and 60
statute miles east and west of a line from 40 miles north northwest
of Harrison AR to 25 miles south southeast of Poteau OK. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU5).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

OTHER WATCH INFORMATION...CONTINUE...WW 374...
AVIATION...A few severe thunderstorms with hail surface and aloft to
1.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A
few cumulonimbi with maximum tops to 500. Mean storm motion vector
28030.

MD 1144 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR WESTERN/CENTRAL KENTUCKY AND FAR SOUTHERN INDIANA

Mesoscale Discussion 1144
NWS Storm Prediction Center Norman OK
0947 AM CDT Fri Jun 06 2025
Areas affected...Western/central Kentucky and far southern Indiana
Concerning...Severe potential...Watch unlikely
Valid 061447Z - 061645Z
Probability of Watch Issuance...20 percent
SUMMARY...A few multicell storms with a marginal hail/wind threat
will be possible through early afternoon. A watch is unlikely.
DISCUSSION...A loosely organized cluster of storms is spreading
eastward across western KY and far southern IN, in association with
a diffuse midlevel perturbation moving along and south of a stalled
front. Destabilization is ongoing south of the front as
temperatures warm into the lower 80s, which will boost MLCAPE into
the 1500-2500 J/kg range over the next few hours. Though there is
modest enhancement to flow above 5 km AGL, flow below is relatively
weak and storms are expected to remain primarily multicellular.
Thermodynamic profiles could support isolated hail near 1 inch
diameter and isolated wind damage with downbursts, but the overall
severe threat appears too marginal to warrant a severe thunderstorm
watch through midday-early afternoon.

Valid 061300Z - 071200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON
AND EVENING OVER PARTS OF THE CENTRAL AND SOUTHERN HIGH PLAINS...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
THE MID MS AND TN VALLEYS...AND OVER SOUTHERN NEW ENGLAND....
...SUMMARY...
Scattered severe thunderstorms are expected across portions of the
central and southern High Plains. Very large hail, damaging winds,
and a tornado threat is anticipated. Isolated severe thunderstorms
are also possible extending into the Tennessee/Ohio Valleys, and
over parts of southern New England. Damaging winds are the primary
concern in these areas.
...Mid MS and TN Valleys...
Morning radar loop shows a mature quasi-linear MCS over eastern OK
tracking into western AR. This system has produced sporadic severe
wind reports overnight, and may continue to pose that risk for a few
more hours. Some weakening is expected through late morning, with
eventual rejuvenation of storms as they spread across parts of KY/TN
and vicinity. Model guidance varies on extent of severe storm
coverage. However, favorable westerly flow aloft, dewpoints in the
70s, and pockets of strong daytime heating will encourage intense
thunderstorm re-development.
...High Plains...
The forecast scenario for today is similar to yesterday, with two
areas of focus for severe thunderstorm activity. One is along the
CO foothills, where moist/southeasterly low-level winds and
moderately steep mid-level lapse rates will yield afternoon MLCAPE
of 1000-2000 J/kg. Storms are expected to intensify by mid-late
afternoon along the foothills and spread southeastward into the
adjacent plains. Forecast soundings show generally straight-line
hodographs, which will promote splitting supercells capable of very
large hail and a few tornadoes. Activity may organize upscale
during the evening over southwest KS and spread across OK overnight.
Farther south, yesterday's and last night's convection has
reinforced a surface outflow boundary which will extend across west
TX. Similar to yesterday, intense supercells are expected to form
in vicinity of this boundary during the late afternoon, posing
another risk of very large hail and a few tornadoes.
..Southern New England...
A plume of seasonally high PW values extends across the OH Valley
into southern New England. Modest air mass destabilization is
expected by mid day with an axis of 1000-2000 J/kg SBCAPE expected
to extend across southern New England by 18z. While deep layer shear
is not forecast to be that strong, adequate flow should exist for at
least some organization. Locally damaging winds are the primary
concern with storms that form along this instability axis.
