.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
MVFR cigs will prevail across the OK sites for most of the period
before lifting to IFR tonight. As that occurs...fog development is
possible...especially when wind speeds relax. Further east across
the NW AR sites. MVFR vsbys and IFR cigs are ongoing at the far NW
sites. Conditions may improve to VFR very late tonight...but fog
developing as skies clear will likely result in MVFR/IFR vsbys.
Conditions are expected improve to VFR at all sites after
15z-16z.

.PREV DISCUSSION... /Issued 1046 AM CDT Sat Apr 22 2017/

DISCUSSION...
Chilly day ongoing as north winds will continue to advect cool
air across all of the region. Ample cloud cover will prevail
through the day as well...resulting in mostly small diurnal rises
in temperatures. Far western zones may see a little sun very late
this afternoon...but confidence remains low for that to occur.
First period elements by and large are in good shape. Made a few
minor tweaks to temperatures based on latest trends. Also adjusted
pops some and removed mention of drizzle. However...will keep an
isolated mention of showers going for the afternoon across NE OK
and NW AR as some echoes continue to rotate through those areas in
cyclonic flow. Warmup to commence tomorrow and continue into next
week. Shower and thunderstorm chances return to the area by
Tuesday night.

Updated ZFP/PFM/AFM out shortly.
