Overall forecast on track. Good radiational cooling conditions will
be seen tonight with mainly clear skies, light winds to calm and a
cold airmass in place. Current forecast has lows from the upper 30s
to lower to mid 40s. Some concern in those areas that are normal a
bit colder than normal, that lows could dip to the lower to mid 30s.
Atmosphere is dry, with KLZK sounding having a precip water value of
0.50 inches, while dewpoint temperatures across AR in the lower to
upper 40s. Temperature and dew point temperature will be close to
saturation around sunrise in parts of AR Saturday, and isolated and
very patchy frost may be seen in spots. It will not be widespread
enough for a frost advisory. Will just mention it in forecast and
other products with late evening update. Otherwise, dry and sunny
for the weekend, with cool mornings, and mild afternoons. (59)

SHORT TERM...Tonight Through Sunday
Fair conditions will continue during this period. A surface high
pressure ridge, centered from southwest Missouri to northeast
Texas, will slide east of the Arkansas by late afternoon
Saturday, allowing for weak southerly flow to develop. Overnight,
this high pressure will promote ideal radiational cooling
conditions. Mid level heights will continue to build over the mid
south during the period. Above normal temperatures are expected
for Sunday afternoon.
LONG TERM...Sunday Night Through Friday
Sfc high pres wl be centered well to the SE of AR at the start of
the pd. A weak CDFNT is fcst to drop SWD into AR later Sun ngt and
Mon before stalling out acrs the FA. Moisture wl be very limited
with this feature...so dry conds wl cont.
The aforementioned fntl bndry wl eventually dissipate as SLY winds
return. This wl allow for a gradual warmup heading into the middle
of next week. Another upr trof/CDFNT wl push EWD and move thru AR
Wed and Wed ngt. Latest data does suggest more moisture assocd with
this storm sys...so maintained low POPS with the assocd FROPA. High
pres wl regain control acrs the FA for the remainder of the PD with
temps staying at abv normal lvls.
