Strong to severe thunderstorms developed across portions of northeastern Oklahoma during the evening of the 15th, ahead of an approaching cold front. The atmosphere ahead of the cold front became very unstable during the afternoon and early evening across eastern Oklahoma, which supported severe thunderstorms that produced large hail up to half dollar size and damaging wind gusts.

.SHORT TERM...
(Tonight)
Issued at 210 PM CDT Thu Aug 15 2024
Weak front currently extends from south central KS into SW OK
with a plume of elevated moisture and isolated convection
remaining draped across across NE OK. Guidance remains in good
agreement in scattered storms developing along the frontal
boundary and also expanding within the mid level moist axis as the
approaching mid level passes the region through the evening.
Effective shear values support some stronger multicell to brief
supercell structure and the strongest storms will be capable of
both hail and locally damaging downburst winds. Storm coverage is
likely to peak by mid evening with a gradual decrease while
focusing more eastward within the strengthening overnight low
level jet.

.LONG TERM...
(Friday through Thursday)
Issued at 211 PM CDT Thu Aug 15 2024
Dangerous heat index / wet bulb globe temps are likely to continue
tomorrow. Uncertainties are somewhat higher tomorrow regarding
temp and dewpoint trends pending the coverage and duration of
tonights convection. A weak sfc boundary is likely to align across
SE OK by mid afternoon and isolated storms are possible in
vicinity of this boundary. Additional storms are expected to
develop across KS and spread southeastward into NE OK by late
afternoon or early evening. This storms will be accompanied by a
stronger corridor of winds aloft and are likely to maintain a risk
of severe weather as they spread southeastward into E OK / NW AR.
As the severe risk wanes by late evening, the developing low
level jet will be orthogonal to the remnant cold pool and there
is potential for a localized area of heavier rainfall totals to
develop through Saturday morning.
Hot and humid conditions will continue into the weekend and
additional heat advisories and/or warnings may be needed.
However, the general trend should be for high temps to cool
slightly as the upper ridge axis shifts more westward. This may
also allow slightly drier air to spread into parts of the region
while also maintaining low chances for daily showers and storms.

Issued at 1211 PM CDT Thu Aug 15 2024
VFR conditions will prevail through the forecast period. By late
this afternoon isolated to scattered thunderstorms are expected to
develop along an outflow boundary across northeast OK. AS such the
NE OK sites will include VCTS from about 00-05z this evening.
Very low probability of direct flight impacts at any one site.
SLim chance of some storms holding together into NW AR, but have
not included at this time due to low confidence.

SEVERE THUNDERSTORM. RISK...Limited. AREA...Northeast Oklahoma. ONSET...After 5 PM. DANGEROUS HEAT. RISK...Significant. AREA...Eastern Oklahoma and Western Arkansas. ONSET...Ongoing. AREA AT GREATEST RISK...Northeast Oklahoma and West-Central Arkansas. DISCUSSION... Dangerous heat is the main concern across eastern Oklahoma and western Arkansas this afternoon and into the early evening, with heat index values topping out in the 105 to 115 degree range. Conditions will improve after sunset this evening. Isolated to scattered thunderstorms are expected to develop ahead of a frontal boundary near the Kansas border later this afternoon through the evening across northeast Oklahoma. The environment is favorable for severe downburst winds from any sustained surface based storms that can get going. Later on this evening, more storms are expected to develop near the boundary across far northeast Oklahoma into northwest Arkansas. While having less of a severe threat, some tendency for the storms to train over the same areas suggests that locally heavy rainfall will be possible. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Local Spotter Activation May Be Needed. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. FRIDAY thru SUNDAY...Thunderstorm Potential...Dangerous Heat Potential. MONDAY...Thunderstorm Potential. TUESDAY and WEDNESDAY...No Hazards. EXTENDED DISCUSSION... A secondary uptick in storm coverage and severe potential will be Friday afternoon and evening as storms move into the region from Kansas. Outside of any relief from rain/storms, dangerous heat will persist thru the weekend. Relatively cooler temps are expected next week as the upper ridge shifts west away from the region. weather.gov/tulsa contains additional information.
