Updated to include the 12Z aviation discussion below...
Some patchy MVFR CIGS and fog will be possible this morning...but
dominant VFR conditions will be seen throughout the rest of the
day into tonight. Winds will become NWRLY...but should remain less
than 10 kts sustained. Rain chances increase just beyond this TAF
.PREV DISCUSSION...(ISSUED 233 AM CDT Tue Apr 24 2018)
SHORT TERM...Today Through Wednesday Night
The slow moving closed upper low has moved east of the region as
of early this morning...with most impacts east of the area. Only
some low to mid level clouds for ERN sections of the state...and
some patchy fog...are ongoing across the CWA early this morning.
Expect some clouds to persist for the ERN third of the area
through this afternoon...with a mostly sunny sky elsewhere. This
sunshine will allow temps to warm into the upper 60s to upper
70s...even with a NW flow at the SFC and aloft.
Mainly dry weather will persist into the overnight hrs
tonight...but a new upper level shortwave will be approaching the
state from the NW for Wed. Will see increasing POPs for some SHRA
and a few TSRA as this upper shortwave moves over the state late
Wed afternoon into Wed night. Instability looks lacking...so the
overall SVR WX threat looks limited. Expect this shortwave to
shift east of the state by the early part of the long term period.
LONG TERM...Thursday Through Monday
Showers/storms will continue to be possible Thursday and Thursday
night, as an upper low moves through northern/northeast Arkansas,
and another cold front passes through. Rain chances will decrease
Friday night, as High pressure moves in. The weekend looks to be
fairly pleasant, with lows in the 40s and 50s and highs mostly in
the 60s and 70s, as well as very little cloud cover. The high will
shift eastward by early next week, with daytime temperatures pushing
80 degrees on Monday.
