Area Forecast Discussion
National Weather Service Tulsa OK
910 PM CST Tue Dec 12 2017

Lowered temperatures a few degrees at some of the locations around
the area that have already cooled off to near the previously forecasted
lows. The nearly calm winds and clear skies have caused temperatures
to fall rather rapidly tonight especially in the colder valley locations.


.PREV DISCUSSION... /Issued 531 PM CST Tue Dec 12 2017/

VFR conditions will prevail through the period. Light winds will
become south-southwesterly and begin to increase near 12Z-15Z
ahead of a cold front that will move through between 16-18Z. Winds
will veer around to more northwesterly behind the cold front with
mid-level cloud deck building in.

PREV DISCUSSION... /Issued 400 PM CST Tue Dec 12 2017/

Fire weather will become a concern again Wednesday as temperatures
warm back to unseasonably warm levels, and afternoon relative
humidities fall to near 20 percent. Winds look like they will
stay below red flag criteria, so will not issue a fire weather
watch at this time, but conditions will need to be monitored. A
cold front will move across the area Wednesday afternoon and
evening, resulting in cooler temperatures for Thursday and Friday.

An upper level storm system is forecast to lift northeast out of
northern Mexico across the southern Plains over the weekend. The
models have not shown good run to run consistency with this
system, with the latest solutions depicting a faster and wetter
system. Will introduce some slight chance to chance pops Saturday
night into Sunday, with dry conditions and above normal
temperatures to follow for the early part of next week.

Went a bit warmer than guidance for high temperatures Wednesday,
but stayed close to guidance temperatures otherwise for the next
couple days.
