.PREV DISCUSSION... /Issued 303 AM CDT Tue Oct 17 2017/

Another cool night is well underway across eastern Oklahoma
and western Arkansas as surface high pressure slides off to
the east of the area. A gradual warming trend is expected
over the next few days as the low level winds become more southerly
with the surface high shifting to the east. Right now, forecasting
Thursday to be the warmest day of the forecast period with cloud
cover increasing on Friday. The winds are also set to increase on
Friday in advance of a cold front expected to affect the region over
the weekend.

Will include a small chance of showers and thunderstorms across portions
of southeast Oklahoma Friday as a southern stream shortwave swings across
the area. The main chance of showers and thunderstorms will occur on
Saturday and especially Saturday night as a cold front moves through
the region. It appears that there will be sufficient deep layer shear
and instability for strong to severe thunderstorms especially Saturday
evening. Locally heavy rainfall will also be a concern during this time.
The showers and thunderstorms are expected to end Sunday morning across
the area as the cold front shifts to the south and east.
