.SHORT TERM...Today through Tuesday Night

Sfc high pres was centered just to the E of AR early this mrng.
Seeing some high lvl clouds stream acrs the area attm, but temps
have still managed to fall to cold lvls. Predawn readings ranged fm
the mid 20s to the mid 30s.

The aforementioned sfc high wl cont to work further EWD today,
allowing S/SE winds to return to the FA. Look for high temps close
to seasonal norms, with readings ranging fm the upper 50s to the mid
60s.

The progressive upr lvl flow pattern wl bring yet another CDFNT thru
AR Tue aftn/night. Best low lvl moisture return ahead of the fnt wl
stay S of the state, so just looking for an incrs in clouds with
this sys. Reinforcing shot of cooler/drier air wl start to advect
into the region Tue night and cont into the long term.

.LONG TERM...Wednesday through Sunday

On Wednesday...high pressure is expected to be building in over
Arkansas at the surface while northwest flow persists aloft with a
large upper level ridge anchored over the southwestern CONUS and an
upper trough/low anchored over the northeast. Wednesday through
Friday are expected to be dominated by shortwave ridging and the
associated large scale forcing for subsidence. Mostly clear skies
are expected as a result which will lead to a cold day on Wednesday
and increasing temperatures through the end of the week.
Temperatures are expected to fall below freezing for most locations
Wednesday night into Thursday morning. By Friday highs are expected
to climb back into the mid to upper 60s with overnight lows in the
mid 40s Friday night.

Another cold front is expected to move across Arkansas on Saturday
but before the cool air arrives behind the front temperatures will
likely climb up to 70 degrees across the state. Limited moisture and
displaced upper level support mean that rain chances remain very low
at this time. Unfortunately this means that ongoing drought
conditions across Arkansas are likely to worsen as another weeks
goes by without any sign of significant rainfall. The dry weather
pattern looks to continue into early next week.
