High pressure continues over the area this evening. Some cirrus
will pass over the area and winds will be light through the
period. VFR conditions will continue.

.PREV DISCUSSION...(ISSUED 253 PM CDT Sat May 30 2020)
SHORT TERM...Tonight Through Monday
Not much going on in the short term, as high pressure will remain
in control. For us, this will mean little in the way of cloud
cover, and temperatures close to or a little below average.

LONG TERM...Monday Night Through Saturday
Quiet weather should be ongoing to start the period. Aloft, large
scale ridging will be in place across the C plains. Two areas of
troughing will be located off the CA coast and off the New England
coast, respectively. At the surface, high pressure will be centered
over the Appalachian Mtns. AR will reside beneath SW flow around the
aforementioned high. Warm humid air will continually advect into the
region replacing dry and cooler air at the surface from the short
term period.

On Tuesday, an upper compact low is expected to lift Nwrd out of MX
into the Srn plains. This compact low will move into a less
favorable environment and within a large area of weak steering flow.
The energy from this system will pinwheel around the periphery of
the surface high, affecting mainly Wrn AR initially.

By Wednesday, a few showers and isolated thunderstorms will be
possible over portions of Wrn AR. Ern AR will remain under the
influence of high pressure and thus temperatures should be higher
across Ern and SErn AR. The upper low will fizzle out just NW of AR,
however upper level shortwave energy is expected to interact with
residual moisture to trigger scattered showers and thunderstorms
across a larger portion of the state on Thursday afternoon. This
activity is expected linger into early Friday before NW flow brings
precip to an end.

Temperatures through mid week will be warm, with readings in the
upper 80s to lower 90s. Added clouds will hold temperatures down
slightly on Wednesday and Thursday but heat index values will likely
range from the lower 90s to near 100 degrees. Much uncertainty
exists with how widespread or scattered showers and thunderstorms
become. The upper level ridge and surface high to our E will serve
to suppress convection, possibly limiting coverage.
