.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
Periodic showers and thunderstorms will continue for southeast
Oklahoma through western Arkansas for a few more hours this
evening, possibly lingering after midnight. Mainly dry conditions
are expected for the northeast OK terminals with MVFR ceilings
continuing overnight. For the rest of the sites, occasional MVFR
ceilings will occur within the heaviest bands of storms this
evening. Clouds will clear by mid morning Friday across eastern
Oklahoma and by mid day for western Arkansas.

.PREV DISCUSSION... /Issued 325 PM CDT Thu Oct 10 2019/

DISCUSSION...

The main forecast concerns are mainly in the first 48 hours of the
forecast. Severe weather and heavy rain/flooding potential thru
tonight and frost/freeze potential Friday night into Saturday are
the main items of mention.

A strong cold front, in association with a large and powerful
upper level storm system moving east across the country, is moving
across eastern Oklahoma this afternoon. The front has cleared
Tulsa, and the severe tstorm watch in effect for Tulsa will be
dropped soon. Strong to severe storms will remain possible along
and especially ahead of the front thru evening with an unstable
and sheared airmass in place. Tornado potential will be limited by
weakening low level shear thru the afternoon. Damaging winds and
large hail are the main threats. An increase in post-frontal
showers and storms is expected overnight as isentropic lift
increases behind the front across eastern OK/western AR. Based on
the latest QPF forecast, which takes into account the potential
for multiple rounds of heavy rain producing storms across SE OK
into NW AR, a flash flood watch was issued thru tonight. Rain
chances will taper off fairly quickly from west to east after 12Z
Friday.

Much colder temps will filter into the region behind the front
tonight. Combine this with the winds, and you get wind chills in
the 30s and even some upper 20s by tomorrow morning. Skies will
clear by Friday night and winds will get light with surface high
pressure nearby. This will allow temps to crater and several areas
will get near or below freezing by Saturday morning. As a result,
a freeze watch has been issued for NE OK, a portion of SE OK, and
far NW AR.

The forecast is largely quiet past the potential freeze Saturday
morning. A band of warm advection generated showers and storms
will spread across the Arklatex Saturday night into Sunday but
this activity should stay south. There will be a chance of storms
again early next week ahead of another front. The best chances
will be in the east/southeast.

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...This Evening and Tonight.
TORNADO.
	RISK...Limited.
	AREA...Southeast of a line from Jay Oklahoma to McAlester Oklahoma
	ONSET...Ongoing...ending by late evening.

SEVERE THUNDERSTORM.

SIGNIFICANT WINDS.
	RISK...Limited.
	AREA...Eastern Oklahoma.
	ONSET...Ongoing.

DISCUSSION...
Widespread storms are ongoing late this afternoon from far northeast
Oklahoma southward into southeast Oklahoma.  These storms are along
and in advance of strong cold front which will continue to surge
eastward during the evening hours. Scattered severe storms are ongoing
across the region with locally large hail and damaging winds the primary
concern.  Low level winds also remain sufficiently sheared to support
a limited risk of tornadoes. The risk of severe weather will end from west
to east associated with the passing cold front.  Additionally, areas
of heavy rainfall have already fallen this afternoon for isolate locations.
The potential for flash flooding will remain into the overnight hours
as additional storms redevelop from southeast Oklahoma into western
Arkansas after the cold front has passed.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Likely.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY...High Wind Potential.
SATURDAY and SUNDAY...No Hazards.
MONDAY and TUESDAY...Thunderstorm Potential.
WEDNESDAY...No Hazards.

EXTENDED DISCUSSION...
Gusty northerly winds and sharply cooler temperatures will prevail on
Friday. The next chance of thunderstorms arrives early next week.
