Area Forecast Discussion
National Weather Service Little Rock AR
217 PM CDT WED JUN 15 2016

.Short term...Tonight through Friday

Not a lot of value added changes will be forth coming this afternoon
as all models continue to advertise the continuation of the hot and
humid weather.

Dew Points in the mid 70s with air temperatures in the lower 90s
have produced heat indices this afternoon over 100 degrees just
about everywhere across the state and over 105 over the majority of
it. With similar conditions expected on Thursday, the heat advisory
will continue.

Upper level ridging will build across the state through Thursday
with the warmest day of the week expected. A weak disturbance will
move across southern Missouri and northeast Arkansas this afternoon
and evening. While a stray shower can not be excluded, most areas
will remain dry and only silent pops will be carried.

Models continue to show a backdoor cold front coming through on
Friday to knock the ridge to the west a little bit and bring in
slightly cooler air although dew points will remain up. This will
lower heat indices just enough to keep the area out of heat advisory
criteria but it will still be quite warm out there. Only minimal
pops are expected wit.DISCUSSION...
TEXTh this boundary.

LONG TERM...Friday Night Through Wednesday

Same song, second verse. Rather monotonous pattern will continue
through the long term periods, minus the humidity of the short term.

Strong nearly-600 decameter ridge will remain anchored over the
southwestern CONUS through the period, expanding and contracting at
times. At the onset of the period, backdoor front will have moved
into Arkansas and likely be washed out, with remnant mesoscale
surface boundaries remaining. At the same time, there will be an
impulse moving around the periphery of the ridge, and these should
give small precip chances Friday night, and possibly into early
Saturday.

The ridge will expand during the weekend, and shut any rain chances
off. With surface flow being predominantly out of the east and
southeast, humidity should be in check.

Ridge will contract again toward the end of the period, possibly
allowing another frontal boundary close to the region. Temperatures
will remain around 3-5 degrees above seasonal averages.

SAG INTO ARKANSAS...AND BRING A CHANCE OF THUNDERSTORMS BACK INTO
THE FORECAST. AT THIS TIME THE THREAT OF ANY SEVERE STORMS WOULD
BE LOW AND ISOLATED. THIS FRONT IS ALSO EXPECTED TO LOWER
TEMPERATURES A BIT AND BRING SOME DRIER AIR TO THE STATE. THIS
WILL LOWER HEAT INDEX VALUES. LATE IN THE WEEKEND AND INTO NEXT
