.SHORT TERM...
(This evening through Saturday)
Issued at 237 PM CDT Thu Jun 5 2025

Diurnally driven convection was ongoing across the state on this
Thursday afternoon. Wind shear was minimal despite SB/MUCAPE values
on the order of 3000-3500 J/Kg. These were your run of the mill
garden variety summertime pop up cells. The strongest of storms
could produce brief gusty winds and perhaps pea sized hail.

Temperatures this afternoon were in the mid 80s to lower 90s with
dew point temperatures largely in the lower to mid 70s. Apparent T`s
were in the 90s to near 100 degrees. A few locations were cooler
than this owing to rain cooled air or mostly cloudy skies. This
shower/storm activity should subside in coverage after sunset.

After today, attention turns to an approaching system from the W and
NW. By Friday morning, upper level energy should traverse the state
from the WNW. Hi-res cam guidance suggests a potential MCS
developing over SE KS/NE OK/SW MO regions and quickly barreling
SEwrd. This system would likely follow the instability axis
between rain cooled air over Nrn AR today with warm unstable air
lifting Nwrd from the gulf which was already in place over much of
Cntrl and all of Srn AR. Strong to severe wind gusts would be the
primary threat with a secondary concern being large hail.
Guidance has consistently hinted towards the complex weakening as
it moves towards Cntrl AR by late-morning. This weakening would
make sense due to expected time of arrival when instability is
near the daily minimum. We will need to watch closely how far this
system progresses into the state before weakening.

Another round of showers and storms will be possible late Friday
night into Saturday morning associated with another piece of upper
level energy moving across the region within background WNW flow.
Again, damaging winds would be the primary hazard followed by large
hail. On and off showers/storms will be possible on Saturday and
Saturday afternoon following the morning convection as an active
upper stream remains in place. By the end of the period, upper
flow should become more NWrly, however unsettled weather is
expected to continue into the long term.

.LONG TERM...
(Saturday Night through next Thursday)
Issued at 237 PM CDT Thu Jun 5 2025

An upper low will drop south out of Canada into the Great Lakes
Region at the start of the long term period. Upper flow over AR will
become more NWRLY Sat night into Sun as this upper low moves into
the Great Lakes Region. Weak upper waves will move SE over AR during
this period...with the first wave dropping SE Sat night into Sun.
This will keep any ongoing convection that develops late Sat
afternoon persisting into the evening/overnight hrs as activity
drops further SE. The daytime hrs on Sun should remain basically dry
behind the departing upper disturbance...but chances for convection
return Sun night into Mon as a new upper disturbance and cold front
moves back into AR.

Chances for precip decrease by Tue as the front drops further south
through AR. There could be some lingering chances across SRN
sections into the middle of the week as the SFC front slows. The
upper trough to the NE will move east by late next week...with flow
aloft becoming less strong over the region. Flow aloft will turn
back to more SWRLY late in the forecast...but will remain generally
weak. As a result...some chances for precip do return...but will
likely be more of the summer-time pulse variety with weak upper
energy overhead at times.

.AVIATION...
(00Z TAFS)
Issued at 559 PM CDT Thu Jun 5 2025

Some isolated to widely scattered SHRA/TSRA will remain possible
this evening...but coverage should decrease with the loss of
daytime heating. A more organized complex of convection looks to
develop west overnight...and move ESE into AR by around sunrise
Fri. This will initially impact the NRN terminals...then if the
complex remains together...further SE over the morning hrs.
Activity by the afternoon will be much more limited in coverage.
