.AVIATION...

VFR conditions will prevail at most locations in Arkansas through
tonight. There will be chances of showers and thunderstorms
across the northern half of the state during this time frame. Given
this, there may be brief MVFR conditions in places due to
precipitation, low clouds, and patchy fog. Any MVFR conditions will
be most likely this morning. Winds today will be south/southwest
at 8 to 14 mph with 16 to 22 mph gusts. Winds tonight will be
south/southwest at 5 to 10 mph. (46)

&&

.SHORT TERM...Today Through Thursday Night

After two to three inch plus rainfall in parts of western
Arkansas on Tuesday, here comes round two. Showers and
thunderstorms will overspread northern into central sections
of the state through tonight. Precipitation will be in response
to a storm system aloft wobbling from the mid-Mississippi Valley
toward the Ohio Valley and a weak cold front drifting into the
region from the north.

Parts of north/west could receive two to four inches of rain
through tonight with isolated higher amounts. Given recent
heavy rain in the Ouachita Mountains of the west and the Arkansas
River Valley west of Morrilton on Tuesday, any additional liquid
could cause high water problems.

A Flood Watch has been posted in parts of the north and
west through tonight.

As the aforementioned storm system wobbles to the east,
yet another system will be on its heels in the central
Plains on Thursday. That will keep the pattern unsettled
for the remainder of the near term. Also, high pressure
along the Gulf Coast will flatten a bit, and this will
allow precipitation to finally build into southern Arkansas.

Temperatures will tend to be at/below seasonal levels
in northern/central sections, and at/above normal across
the south.

&&

.LONG TERM...Friday Through Tuesday

High pressure ridging across the southern United States will
gradually move westward through the period, with several frontal
boundaries and upper level lows/troughs moving east through the
mid CONUS.

The initial synoptic setup will prevent the frontal boundaries from
advancing southeastward through Arkansas, resulting in the features
stalling across northern portions of the region. This, combined with
the several impulses rotating through the mean flow will provide a
favorable environment for widespread rainfall.

Continue to anticipate the ridge of high pressure retreating towards
the Desert Southwest by the end of the period and early next week,
allowing a deeper upper level low to develop across the Great Lakes
region. With this slight change in the synoptic setup, we could see
a couple of cold fronts move further south through the state.

Chances for rainfall each day will help keep forecast highs down in
the mid 80s to lower 90s, and overnight lows in the 70s.
