Eastern Oklahoma/Northwest Arkansas Weather Summary
National Weather Service Tulsa OK
845 PM CDT Fri Apr 20 2018

High level cirrus clouds gradually increased over the area this
afternoon, otherwise fair skies prevailed over eastern Oklahoma
and northwest Arkansas. East to southeast winds also gradually
increased in response to a tightening pressure gradient and
approaching system system to our west. Wind speeds of 10 to 15 mph
were common, with occasional higher gusts of 25 to around 30 mph.
High temperatures around the area today varied from the mid 60s to
lower 70s.

At mid evening, high level cirrus clouds continued to overspread
area skies, with a few mid level clouds also observed across
northern portions of the area. Further to the west, a complex of
showers and thunderstorms were ongoing across western Oklahoma and
the Texas Panhandle. East to southeast winds of 5 to 10 mph were
common around the area this evening, with temperatures ranging
from the mid 50s to lower 60s.

Clouds will continue to gradually increase across area skies
through the evening as the system to our west slowly progresses
east. The chance for widespread rain showers will also be on the
increase, mainly after midnight as this system nears. The rains
will begin west of highway 75 before spreading east across the
rest of the area during the night and early morning on Saturday.
Temperatures overnight will fall into the mid to upper 40s.
Widespread showers are expected across the area through the day
Saturday, along with the potential for isolated thunderstorms.
Temperatures will be held in check tomorrow with the anticipated
cloud cover and precipitation. As a result, daytime highs will
only warm into the lower 50s to lower 60s.
