.PREV DISCUSSION... /Issued 234 AM CST Wed Nov 22 2017/

DISCUSSION...
Significantly colder today behind strong front as 1030 MB surface
high settles over the region with light winds this afternoon. The
cold weather however will be short lived with warming trend on
Thursday and especially Friday as southerly winds begin to
increase. There will be at least a limited fire danger threat on
Friday as temperatures warm back into the lower to mid 70s across
eastern Oklahoma Friday afternoon with minimum RH values falling
to around 35 percent. Region remain extremely dry, with cured
vegetation, and any fires that develop could spread quickly.

Another dry cold front will move through during the day Saturday
with temperatures back to near or just slightly above normal
through the weekend. Gusty south winds will again increase on
Monday ahead of approaching upper trough moving through the
northern Rockies. Fire danger will once again become a concern
given the limited moisture return with temperatures back into the
upper 60s to lower 70s. Precipitation chances finally return
Tuesday afternoon into Tuesday night with next cold front.
Depending on speed of front, best chance for beneficial rainfall
will be south of Interstate 44 across far southeast Oklahoma and
west-central Arkansas. At this time, it appears limited
instability will preclude any thunderstorm development with
frontal passage.
