SHORT TERM...Tonight Through Sunday
Scattered showers and isolated thunderstorms continue to develop
this afternoon, ahead of a surface boundary across northern
Arkansas. Atmospheric conditions are quite moist ahead of the
boundary. 12z KLZK sounding indicated a precipitable water value
(2.4 inches) that ranks in the top ten of values for the month of
July for this site.

The front will accelerate southward overnight, and will clear the
southern sections of the forecast area by early morning.
Precipitation forecasts will reflect the katafront nature of the
convective development.

The airmass associated with this boundary will bring a noticeable
change to recent apparent temperature trends. High temperatures on
Saturday and Sunday will average 5-8 degrees below normal.

LONG TERM...Sunday Night Through Friday
Northwest flow will be in place for the weekend, providing continued
relief from the heat and at least the possibility to usher weather
systems into the region late in the period. Max temperatures will
top out in the 80s through early next week and gradually warm back
into the 90s by mid week. As of now, models are not picking up on
any rain makers until late next week. Introduced POPs on Thursday
but would expect timing and chances to be more fine tuned in the
coming days.
