Widespread MVFR to IFR conditions are expected through much of the
taf period as an upper level low continues to slowly make its way
across the state. Rain will begin to taper off from west to east by
daybreak Thursday morning but widespread low cloud cover will linger
for several hours after. Some patchy fog may occur prior to 12z at
khro/kbpk with occasional br elsewhere. Winds will be variable at
times due to the circulation around the low, with north-northwest winds aoa
10kts being most common through the period. Conditions will improve
to VFR by Thursday afternoon, likely by 27/00z for most terminals.

short term...tonight through Friday
data from klzk radar indicate an area of light to briefly moderate
precipitation across west central, to northeast sections of the
forecast area. Isentropic lift in the 600-700 hpa layer is promoting
this rainfall. This lift will weaken during the evening hours.
Scattered light precipitation will affect northern and central
sections later night, as upper level energy moves over the state.

Weak energy in northwesterly flow will move through late mid south
late Thursday, and will promote widely scattered, light
rainfall/sprinkles for Thursday night.

Long term...Friday night through Tuesday
still looking like a pleasant weekend in store for the forecast area as high
pres wl be in control. Northwest flow aloft wl bring a weak front into Arkansas
from the northwest Sat night/early sun. East/NE wind flow behind this feature
wl bring just a reinforcing shot of cooler/drier air to the region.

Heading into early next week, warmer air wl start to advect into Arkansas.
Sfc high pres wl shift ewd, with south winds returning. Also, upr
heights wl incrs as ridging aloft moves into the mid-south. Highs
Mon and Tue wl warm well into the 70s and lower 80s.

A more progressive upr flow pattern by the middle of next week is
fcst to bring a new storm system ewd into the plains states. Sctd
rain showers/thunderstorms and rain wl return to the forecast as a result.
