Area Forecast Discussion
National Weather Service Little Rock AR
401 AM CDT Fri Jul 21 2017

.Short term...Friday through Saturday night

Another day of widespread heat and humidity is expected across the
region today as upper level high pressure continues to dominate.
Temperatures once again will average above normal with dew points
remaining in the oppressive category. As such the heat advisory will
continue for the entire forecast area. Afternoon heat indices will
range from 100 to 110 degrees.

Precipitation will remain spotty in nature and once again diurnally
driven. Much like the past few days, the best chances of showers and
thunderstorms will be over the south but they can not really be
discounted anywhere.

The ridge will weaken a bit on Saturday as a cold front drops into
central Missouri by the end of the period. In addition to the front,
a weak trough will be centered along the Gulf Coast. As such, it
looks like temperatures will be a touch cooler with slightly higher
chances of precipitation. The heat advisory will continue for
central and northern sections on Saturday but more cloud cover is
anticipated over the south with the aforementioned trough which may
keep heat indices below advisory criteria.

.Long Term...Sunday Through Thursday

Upper high pressure will continue to be over the nations mid section
to begin the long term period with an area of low pressure over the
Gulf of Mexico. The high is expected to weaken Saturday and this
will allow the upper low to move northwest toward Arkansas. This low
will be near the Gulf Coast Sunday and Monday. High pressure builds
over the western U.S. Tuesday and spreads east Wednesday. The large
high pressure area will remain over much of the U.S. through
Thursday.

On Sunday, a chance of showers and thunderstorms will return to
the forecast as the area of low pressure nears the state and the
high pressure weakens. Also, a cold front drops into southern
Missouri Monday and stalls Tuesday in north Arkansas. The front then
moves back to the north as a warm front on Wednesday. Expect rain
chances through the period with the highest pops Sunday through
Tuesday. Below normal temperatures are expected through the period
with considerable cloud cover and rain chances.
