National Weather Service Little Rock AR
630 AM CDT FRI JUL 29 2016

Widespread MVFR to IFR conditions due to low clouds exist this
morning but should burn off this morning with VFR conditions
returning. Otherwise isolated convection is expected to develop
once again with the best chances in the afternoon. An upper level
disturbance will drop down out of Kansas and Missouri tonight for
a chance of precipitation towards morning. Light winds will occur.




Short Term...Today through Saturday night

All short term / high resolution models continue to show unsettled
conditions continuing through the period with the possibility of
mesoscale convective systems moving through both Friday and Saturday
nights. Models are actually in good agreement as far as timing is
concerned but rainfall amounts are all over the place with the NAM
seemingly way overdone on its QPF.

Upper pattern dominated at this time by upper level high pressure
sitting over the four corners and a broad mid level trough over the
upper mid west through the Ohio Valley. On the surface, a quasi
stationary boundary will remain in the vicinity of the Arkansas and
Missouri border.

Models all continue to support the idea of generally weak, nocturnal
disturbances moving through the prevailing flow and interacting with
a moisture choked airmass characterized by PWATS hovering around 2
inches. If these meso scale systems do come to fruition, locally
heavy rain can not be excluded. The aforementioned surface boundary
will begin to lift north Saturday night and better precipitation
chances will shift that way in response. Temperatures will average
close to seasonal norms.

Scattered convection occurring at this time over northwest Arkansas
in advance of a more significant area of precipitation moving into
central Kansas. Both the HRRR and ARW solutions have this area of
rain expanding as it moves into the CWA later this morning and into
the afternoon. As a result, precip chances will be brought into the
high scattered category.

Will need to carry precipitation chances through the period not only
for the possible MCS development at night but also for the myriad
of meso scale boundaries currently lurking, and possible new ones
being introduced by any convection.

Long Term...Sunday through Friday

The extended period will start with a ridge of high pressure across
the southern U.S. This high will expand northward through Monday and
Tuesday. By Wednesday the high will be over much of the U.S...and
this will continue into Friday.

The pseudo-stationary front over southern Missouri on Sunday will
move back to the north Monday through Wednesday. This will lead to
lower precipitiaton chances for next week as well as warmer
temperatures. After highs in the upper 80s to mid 90s Sunday,
temperatures will return to the lower to mid 90s Monday through


.LZK Watches/Warnings/Advisories...NONE.
