Area Forecast Discussion
National Weather Service Tulsa OK
631 PM CDT Tue Jun 6 2023

...New AVIATION...

.SHORT TERM...
(Through tonight )
Issued at 226 PM CDT Tue Jun 6 2023

Scattered storms have developed on the moist side of a
surface theta-e gradient from southeast Kansas and
northeast Oklahoma into northwest Arkansas.  With
scattered storms in the favored terrain areas of
west-central Arkansas and southeast Oklahoma.  A
few of the cores have been strong with a fair amount
of smaller hail.  An isolated severe storm is possible
with hail and local microbursts.  This activity
will fade with sunset.  Some patchy fog is possible
toward morning... especially where rain falls this
evening.

&&

.LONG TERM...
(Tomorrow through Tuesday)
Issued at 226 PM CDT Tue Jun 6 2023

Only minor changes to the pattern are expected on
Wednesday with perhaps the afternoon and evening
convection more restricted to the terrain of
southeast Oklahoma.

An uptick in showers and thunderstorms appears likely
on Thursday as the western tail of a mid-level trough
diving south through the Mississippi Valley brushes
the area with moist and potentially unstable air in place.
Similarly on Friday, perhaps less coverage, scattered showers
and storms will be in the areas as the western fringe of the
cyclonic flow aloft continues to brush the area.

A front appears like it will be forced into or near
the area on Saturday and Saturday night by the western
fringe of the cyclonic flow aloft.  That results in
higher shower and thunderstorm chances.

Later this weekend we will see the beginning of a
pattern shift that brings faster winds aloft over
the region, with the fastest flow likely Tuesday and
Wednesday.  Depending on boundary positions, the
potential for a more organized convective event will
increase.

&&

.AVIATION...
(00Z TAFS)
Issued at 631 PM CDT Tue Jun 6 2023

Afternoon convection has moved away from most of the TAF sites,
with the exception of KRVS. Will include VCTS and TEMPO thunder
mention for that TAF. Otherwise VFR conditions prevail for the
most part. KFYV has consistently had fog, and there was rain at
the airport today, increasing the potential. Thus will insert
TEMPO IFR fog mention for this forecast.

much of Eastern Oklahoma.

.DAY ONE...This Afternoon and Tonight.

SEVERE THUNDERSTORM.
	RISK...Limited.
	AREA...Eastern Oklahoma; Western Arkansas.
	ONSET...Ongoing...ending this evening.

DISCUSSION...
Scattered afternoon storms will pose a limited risk of damaging
winds and possibly marginally severe hail. The damaging wind and
large hail threat will be pretty localized if it occurs. Storms
will dissipate this evening with the loss of daytime heating.

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

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY...No Hazards.
THURSDAY thru SUNDAY...Thunderstorm Potential.
MONDAY...No Hazards.

EXTENDED DISCUSSION...
After a break on Wednesday, storm chances will return for Thursday
with more widespread storm coverage on into Friday as a frontal
boundary moves into the region. The main threats during this time
will be brief heavy downpours, dangerous lightning, and marginally
severe wind gusts. The potential for more organized thunderstorms
may increase over the weekend as a stronger cold front pushes
into the area from the north.
