...UPDATE...
.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG.
VFR conditions should prevail through the period. A few
thunderstorms remain close enough to the AR terminals, as well as
MLC, to keep a VCTS mention in for the first hour or two of the
valid TAF period. Activity should be more isolated tomorrow
afternoon, and as such, will leave any TSRA mention out of the
TAfs for now.

.PREV DISCUSSION... /Issued 316 PM CDT Thu Jul 12 2018/
DISCUSSION...
The heat remains the biggest concern thru the weekend, with
afternoon storm chances a secondary concern.
GOES 16 PWAT shows relatively drier conditions over the region
compared to yesterday, as some drier air wrapped around the south
side of the mid level ridge. This also appears to be affecting the
dewpoint field, as mixing has had more of an impact on the
dewpoints this afternoon. Nevertheless, borderline heat advisory
conditions are occurring.
We are in the midst of a heat wave. Climatologically, we are very
near the hottest time of year, basically from mid July to mid
August, where average highs reach their peak for the year across
the region. Finally, in a year that has thrown climo out the
window for the most part, the weather will be following climo.
Afternoon high temps will continue to climb and will land in the
triple digits by the weekend in several areas. The heat combined
with the humidity will likely necessitate at least heat advisories
each afternoon thru the weekend.
Coverage of afternoon storms has decreased some from this time
yesterday overall, with slightly higher coverage in the NW AR
terrain, likely due to the relatively lower PWATs. Rising mid
level heights over the region on Friday, as the mid level high
begins its trek overhead for the weekend, suggest that afternoon
storm coverage will be isolated at best.
Storm chances will increase some across the north and east early
next week in association with a weak front. There will be some,
albeit brief, relief from the heat by Tuesday. The heat returns
again for Wednesday ahead of the next, stronger front. Yes, the
GFS and ECMWF are still advertising that a cold front will be
strong enough to push thru the forecast area late Thursday into
Friday, part of a transition in the upper pattern consisting of
the retrogression of the mid level ridge and trough formation over
the Great Lakes. This front will likely bring a little relief in
relatively cooler temps, but the bigger relief will be from the
humidity. There is some promise of much nicer weather toward the
end of next week and on into the following weekend.

THUNDERSTORMS WITH DANGEROUS LIGHTNING. RISK...Limited. AREA...Eastern Oklahoma and Northwest Arkansas. ONSET...Ongoing. DANGEROUS HEAT. RISK...Elevated. AREA...Eastern Oklahoma and West Central Arkansas. ONSET...Ongoing. DISCUSSION... Widely scattered thunderstorms have developed this afternoon across portions of eastern Oklahoma and northwestern Arkansas in the hot, humid, and unstable air mass that is in place across the region. Isolated to widely scattered thunderstorms will continue to develop through early this evening, before all of this activity dissipates by around sunset. The strongest storms this evening will have the potential to produce strong gusty wind. The combination of hot temperatures and high humidity has resulted in heat index values from 105 to 108 degrees this afternoon across much of eastern Oklahoma and west central Arkansas. These conditions will improve by late evening as temperatures decrease by around sunset. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Spotter Activation Not Expected. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. FRIDAY...Thunderstorm Potential...Dangerous Heat Potential. SATURDAY...Dangerous Heat Potential. SUNDAY through TUESDAY...Thunderstorm Potential...Dangerous Heat Potential. WEDNESDAY...Dangerous Heat Potential. EXTENDED DISCUSSION... A hot and humid air mass across eastern Oklahoma and northwestern Arkansas will continue to support mainly afternoon and evening thunderstorm development into early next week, although the coverage of this activity is expected to decrease this weekend due to a high pressure ridge building into the area. Organized severe weather is very unlikely in this pattern but the potential will exist for the strongest storms each afternoon to produce isolated strong downburst wind approaching 60 mph. Dangerous heat will continue across the area into early next week as hot temperatures combine with high humidity. weather.gov/tulsa contains additional information. 69
