Area forecast discussion, Jun 13, 1:50 PM CDT, 4 hours 1 minute before

Area Forecast Discussion
National Weather Service Little Rock AR
150 PM CDT Wed Jun 13 2018

.SHORT TERM...Tonight Through Friday
Scattered convection is rejuvenating this afternoon with a little
better coverage than yesterday at this time. Although organized
severe weather will be low, frequent lightning and gusty winds will
accompany these summertime thunderstorms. Also important to note
will be storm motion and the threat for brief heavy downpours.
With little to push these along, the storm motion will be slow and
the threat exists for some thunderstorm training.

Over the last few days, clouds and bouts of rain have kept
temperatures in check. As we head into the end of the week, our
rain chances will diminish and heat index values will be on the
rise. This will need to be monitored over the next few days for
heat advisory considerations.

&&

.LONG TERM...Friday Night Through Wednesday
Saturday and Sunday will continue to be warm, as the ridge starts to
break down. Initially, any storms will be widely scattered,
diurnally driven. With the high humidity continuing, and
temperatures well into the 90s, afternoon heat index values could
range between 100 and 105 both days.

Fortunately for us, it does look like the ridge will continue to
break down/contract/displace itself (whatever you want to call it).
Either way, we will have a healthy dose of tropical moisture coming
up at us from the Gulf of Mexico, and this will allow us to see
decent rain chances over much of Arkansas. As an added bonus,
temperatures will be cooler as well (though they will depend on
cloud cover and any rain that falls). Temperatures will be much
closer to average for this time of year.&&
