.AVIATION...

Showers and isolated thunderstorms have developed over the
northern terminals along a slow moving cold front located over that
part of the state. This boundary will move into central Arkansas
on Sunday where it will meander for a few days. As the front moves
south, showers and isolated thunderstorms and a wind shift will
accompany it. VFR conditions initially will deteriorate to MVFR and
occasionally IFR conditions in the wake of the front. The front will
not make it to KLLQ so VFR conditions will prevail there.

.PREV DISCUSSION...(ISSUED 654 PM CDT Sat Mar 31 2018)
AVIATION...

VFR conditions will continue for most of the terminals this
evening with MFR conditions possible across the northern
terminals. A cold front will move through the majority of the state
during the period with showers and isolated thunderstorms
expected to develop along the boundary along with a wind shift.
The front looks to stall north of KLLQ. MVFR to IFR conditions
will develop in the wake of the boundary for all terminals except
KLLQ with showers or VCSH.

PREV DISCUSSION...(ISSUED 247 PM CDT Sat Mar 31 2018)
DISCUSSION...

Main concerns in this forecast cycle are chances of convection
over the weekend and into next week. Any risk of strong to severe
storms early in the coming week. Colder temperatures with
possible near freezing temperatures over northern AR. Finally some
risk of heavy rain over several days and elevating area rivers
even more than they are currently from the last heavy rain event.

Saturday afternoon, the upper level short wave continues to move
across the region and has developed scattered light showers over
northern AR, while a few thunderstorms over MO. The convection
will continue to move to the east. Some of the convection has been
elevated, due to low moisture levels. Clouds have increased over
northern northern AR with this shortwave. At the surface, the
high pressure was well to the east of AR, and a south flow will
gradually increase moisture levels through the day. Moisture
levels did started out low this morning, with dew points mainly in
the 40s over AR, and these continue into Saturday afternoon. Also,
morning sounding precip water values were only 0.46 inches at
KLZK, while at KSGF 0.57 inches. Temperatures this afternoon were
in the 70s over central and southern AR, while 60s in the north.

SHORT TERM...Tonight Through Monday

Forecast will start with POP over northern AR this afternoon to
evening, then the system moves east as the cold front sags south
into AR and the rain and convection also sags south Saturday
night. Sunday, the cold front sags to central AR, and develops the
convection over much of the state. Winds do turn north to
northeast on Sunday, and keeps weather conditions much cooler and
breezy over the north and central, while a south wind holds over
the south. Convection does weaken a bit on Sunday as the upper
short wave pushes east, but clouds and light convection will still
be possible. Highs on Sunday will only be in the 40s to lower 50s
north, 50s to lower 60s central, and warmer south in the 60s to
some 70s south of the cold front. Lift does decrease Sunday night,
but the unsettled weather pattern holds in to the coming week,
keeping some chance of convection in the forecast. Monday morning,
temperatures over far northern AR may be close to freezing, and an
advisory may be considered in later forecasts. Any winter weather
would be spotty and no impacts expected.

LONG TERM...Monday Night Through Saturday

The progressive upper lvl flow will keep an active wx pattern in
place acrs the Mid-South through much of the PD. Main forecast
concerns wl cont to be temp trends, along with the timing and
extent of rain chances with each storm sys.

A frontal bndry wl be in the process of lifting Nwd acrs AR Mon
night. Plan to keep some small PoPs in the fcst, mainly for
locations along and N of the bndry. Most locations wl actually see
their low temps reached early in the night, with readings actually
gradually rising overnight as south winds incrs.

Meanwhile, new storm system/CDFNT wl be quickly apchg AR fm the W
early Tue. Model solutions today have actually been trending faster
with the Ewd progression of the storm system. The assocd CDFNT looks
to move thru most of AR by late Tue evening, about 6 hours faster
than previously shown. Showers/storms wl bcm likely along and ahead
of the FROPA, esp over the SE half of the FA.

With the front expected to push thru quicker, the potential for any
organized strong/svr storms still looks to be limited to a narrow
window Mon aftn/early evening acrs mainly the SE half of the FA.
Convective parameters show MUCAPE values apchg 1500 J/KG ahead of
the fnt, along with some CIN in place ovr Cntrl/Ern AR. Fcst
soundings show SRH values of 200-225 m*2/s*2.

Canadian high pres wl bring colder/drier airmass into AR for
midweek. Parts of N AR still look to see temps drop close to the
freezing mark Wed and Thu mrng. Airmass wl begin to moderate
starting late Thu as the high shifts Ewd and Sly flow returns.

Yet another storm system wl bring rain chances back to the area Fri
and Fri night. Some timing differences noted with the timing of this
feature so kept PoPs in chance category. A reinforcing shot of
cooler air wl again heading into next weekend.

This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...Today and Tonight

Isolated to scattered showers will increase through this evening
into tonight. A few thunderstorms are possible, although the
threat for strong storms is very low.

Breezy south to southwest winds at 10 to 20 mph will continue
through early evening before subsiding tonight. Caution is advised
on area lakes and rivers through the remainder of this evening.

.DAYS TWO THROUGH SEVEN...Sunday Through Friday

Chances for showers and thunderstorms will be in place Sunday into
the middle of next week. The threat for widespread heavy rainfall
remains low. A few strong storms may be possible Tuesday, but some
question remains regarding the threat for widespread strong to
severe storms at this time.

Attention will then turn to overnight low temperatures, which will
need to be monitored closely Wednesday and Thursday of next week
across northern Arkansas. Temperatures are expected to fall near the
freezing mark which could harm sensitive vegetation.

Another cold front is expected to move through the state by late
next week which could bring another chance for showers and
thunderstorms to the state.

.Spotter Information Statement...

Spotter activation is not anticipated.
