Updated to include 06z aviation discussion below.

.AVIATION...

A period of MVFR conditions may develop near sunrise as low clouds
develop. But, VFR conditions should return by mid-day. Isolated
to scattered showers/storms will be possible Wednesday, mainly
across NE AR with some activity potentially impacting northern and
central AR terminals. Sfc winds will be out of the SW, gusty at
times.

DISCUSSION...

Updated to include the 00Z aviation discussion below...

AVIATION...

Some isolated convection will remain possible late this afternoon
into the early evening hrs...mainly across the NRN/NERN portions
of the area. Otherwise...chances for precip overnight will be
relatively low. There may be some MVFR conditions around sunrise
at some sites. Some afternoon convection will again be possible
at all terminals...but best chances may be across the NRN
terminals.

PREV DISCUSSION...(ISSUED 219 PM CDT Tue Jun 30 2020)

SHORT TERM...Tonight Through Thursday...

During the remainder of the short term, a weak ridge will continue
to build across the midsection of the country, with upper level
trofs remaining over the east and west coast respectively.

At the surface, a moist southerly flow will continue, allowing
dewpoints to remain in the 70's thru the period.

With the ridge building across the area and the absence of any
synoptic scale features, afternoon and evening thunderstorm
activity should be less prominent thru the short term period.

The greatest concern at the moment will be heat index values
tomorrow and Thursday. With high dewpoints and temps in the 90's in
most areas, heat indices tomorrow should top out at 105 or
greater across most areas, excluding higher terrain. With this in
mind, I will issue a heat advisory starting at noon tomorrow thru
7 PM Thursday. Technically, one or two counties in the southeast
may not quite reach a heat index of 105 tomorrow (it will be
close), but those areas will reach or exceed 105 on Thursday. For
the sake of simplicity, I opted to include those areas both days.

LONG TERM...Thursday Night Through Tuesday...

Upper level ridging will be in place over much of the central and
southern portions of the CONUS by the end of the week. A 500mb
trough will be moving south around the east side of the high through
the MS valley region. Meanwhile, a surface boundary will move
southward, passing through the state providing rain and thunderstorm
chances, mainly over the eastern portions of the state, though the
rest of the state will have chances for diurnally driven afternoon
showers and storms.

A cutoff low will develop over the Gulf states this weekend and will
provide additional rain chances for the state through the first part
of next week. Highs will be in the upper 80s to lower 90s, with lows
in the upper 60s to lower 70s.

This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...Tonight

A few thunderstorms will remain possible overnight over far
northeast and eastern sections of the area. While the overall
threat for severe weather is low...some gusty winds and small hail
could be seen with any storms that form. Locally heavy rainfall
may also be seen. Otherwise...the threat for hazardous weather
will remain low through tonight.

.DAYS TWO THROUGH SEVEN...Wednesday Through Monday

The threat for organized severe weather will remain low through much
of the week. Scattered showers and thunderstorms are expected
daily with the best chances during the afternoon through early
evening hours across eastern Arkansas. While a few stronger storms
can not be ruled out, locally heavy rainfall and isolated strong
wind gusts are the only concerns.

With abundant moisture in place at the surface and temperatures
expected to climb into the 90s, heat indices are expected to exceed
105 across parts of the state from Wednesday through Friday. Heat
indices may be the highest Thursday, with values potentially
approaching or exceeding 110.

.Spotter Information Statement...

Spotter activation will not be needed.
