Area Forecast Discussion
National Weather Service Tulsa OK
541 PM CST Mon Feb 19 2018

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
IFR conditions will prevail at KBVO until a warm front moves north
of there by around 05Z. Otherwise, VFR to occasional MVFR ceilings
will prevail this evening, with MVFR ceilings prevailing after
06Z. Scattered showers and thunderstorms will be possible at just
about any time, with the timing at any one site very difficult to
pinpoint. Showers and storms will become more widespread Tuesday
as a strong cold front moves south across the area, with
widespread rain continuing well behind the front. Gusty south
winds will shift to the north following the passage of the front
Tuesday. LLWS will be mentioned at KFSM overnight tonight into
Tuesday morning.

&&

.PREV DISCUSSION... /Issued 245 PM CST Mon Feb 19 2018/

DISCUSSION...
Strong cold front currently located near a OKC/BVO line is expected to
stall by late afternoon/early evening and begin moving back north as
a warm front. A narrow corridor of modest surface based instability
has developed along/just ahead of boundary across northeast Oklahoma
with CAPE values running around 1000 J/KG. Any storms that develop
near front this afternoon/evening could be marginally severe with
wind/hail, including a limited tornado threat given the strong low
level wind fields present.

More widespread showers with scattered thunderstorms are expected by
Tuesday morning as the cold front pushes back south into northeast
Oklahoma. Precipitable water values remain off the chart high for this
time of year with some areas already approaching 1.5 inches. Locally
heavy rainfall is expected as the front slowly progress through the
area during the day Tuesday into Tuesday night with widespread 2 to
4 inch rainfall totals expected with locally higher amounts possible.
Will therefore go ahead and issue a flash flood watch for portions
of eastern Oklahoma and northwest Arkansas, generally south of
I-44, starting Tuesday morning and continuing through Tuesday
night. The heavier rainfall should begin to shift southeast of the
area Wednesday morning. Still a chance precipitation could
transition to freezing rain Tuesday night into early Wednesday
morning however it appears at this time that accumulations should
remain relatively low. If temperatures drop below freezing quick
enough across far northwest Arkansas that area could have a little
better chance for some ice accumulations.

Very active weather pattern will continue for much of the week with
multiple chances for heavy rainfall. Another upper trough will dig
into the southern Rockies on Thursday with a strong upper jet
streak lifting northeast into the Central plains. Areas of rain
with embedded thunderstorms will spread into eastern Oklahoma and
northwest Arkansas Thursday afternoon into Thursday night. Frontal
boundary stalls over the region Friday into Saturday with a continue
chance for heavy rainfall as showers/thunderstorms train over the
same areas. The ground will likely already be saturated and therefore
a significant threat for flash flooding/river flooding appears
likely.

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

	AREA...Northeast Oklahoma.
	ONSET...Late afternoon and evening.

SEVERE THUNDERSTORM.
	RISK...Limited.
	AREA...Northeast Oklahoma.

	AREA...Eastern Oklahoma and northwest Arkansas.
	ONSET...Tonight.

SIGNIFICANT WINDS.
	RISK...Limited.
	AREA...Eastern Oklahoma and northwest Arkansas.
	ONSET...Ongoing.

DISCUSSION...
An active evening and overnight period as a cold front pushes in
from the north this afternoon and evening. Another round of
thunderstorms are expected to develop along and ahead of the cold
front by this evening with threat for marginally severe storms,
including a large hail and limited tornado threat. The greatest
threat for severe storms will remain generally north of Interstate
40.

Further south...the primary concern will be storms producing
locally heavy rainfall across southeast Oklahoma up through
northwest Arkansas. Several inches of rainfall are expected along
this axis through Tuesday with an increased concern for flooding
and flash flooding.

Southerly winds will continue to remain gusty tonight and Tuesday
with gusts of 25 to 30 mph common.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
WEDNESDAY...Winter Weather Potential...High Wind Potential.
THURSDAY...Thunderstorm Potential...Heavy Rain Potential.
FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY...Thunderstorm Potential.
SUNDAY...No Hazards.

EXTENDED DISCUSSION...
Several rounds of widespread shower and thunderstorm activity are
expected throughout the week, with the first round of significant
rainfall expected Tuesday and Tuesday night as the cold front
begins to push into the region. Locally heavy rainfall is likely
across portions of southeast Oklahoma into northwest Arkansas with
around 1 to 3 inches of rain possible as these locations will be
within a deep moist axis.

A period of light freezing rain will be possible across parts of
northeast Oklahoma late Tuesday night into early Wednesday
precipitation that lingers before temperatures rise above
freezing. There still remains uncertainty concerning icing
potential, so stay aware of the latest forecasts.

Warmer temperatures for the latter part of the work week will
coincide with additional chances for widespread, heavy rainfall.
The deep moist axis will once again setup across southeast
Oklahoma and northwest Arkansas, and additional amounts will have
the potential to create flash flooding and mainstem river
flooding by late Thursday or Friday, particularly areas that
remain saturated by the heavy rainfall earlier in the week.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
With a very unsettled pattern in place for this week, please pay
attention to the latest updates, and includes any flash flood and
river flood watches that may be posted given the current flood
potential. Overall rain amounts and areal coverage of rainfall
will be refined with later forecasts.
