Area forecast discussion, Jul 3, 5:40 PM CST, 1 hour 25 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 640 PM CDT Mon Jul 3 2017 .DISCUSSION... The discussion for the 00Z TAFs can be found below. && .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. The main concerns for aviation will be timing of storms and then potential for low cigs in the wake of the storms on Tuesday morning. The unsettled weather pattern continues tonight into Tuesday. A complex of storms will sweep into the region from the west this evening for the NE OK sites, and after midnight for the SE OK and NW AR sites. Expect IFR or MVFR vsbys and windy conditions with the storms. Latest data suggests that a period of low MVFR, possibly even IFR briefly, cigs will spread over most of the sites in the wake of the storm complex Tuesday morning. Conditions will trend toward VFR as the day progresses, with too low a chance for more storms to mention in the forecast at this point. As a side note, some late afternoon/early evening elevated storms just north of the Tulsa airport may impact the airport if they build south on any outflow. These storms will be weaker than the storms to arrive later tonight. Lacy && .PREV DISCUSSION... /Issued 335 PM CDT Mon Jul 3 2017/ DISCUSSION... Attention is focused on thunderstorm potential this evening and overnight. MCV is noted in water vapor imagery, currently over south central Kansas. This feature is helping storm development just south of Pratt. Strongest low level convergence is located over the eastern TX panhandle where an old outflow boundary extends southeast into central Oklahoma. The latest model solutions support a convective complex initiating across northwest OK by late afternoon. Current thinking is that storms will organize into a linear MCS, arriving into northeast Oklahoma between 9-10pm and into the Tulsa area between 10pm-12am, and into western Arkansas after 1-3am. However, storms are already ongoing across far portions of Osage County, and scattered storm chances remain late this afternoon and early evening, ahead of the more organized system late. The potential for scattered showers and thunderstorms will continue through the Fourth of July. The best chance of storms will be Tuesday morning, associated with the overnight MCS. By Tuesday evening, it appears the higher chance for storms will have shifted into northwest Arkansas, associated with an upper wave. Temperatures tonight through Wednesday will be cooler than normal with widespread clouds and convection. By Thursday and Friday, temperatures will return to near seasonal readings, in the lower to mid 90s with no rain in the forecast. The next chance for storms arrives by Saturday into Sunday, although these chances will be on the low side given upper ridge building to our west. && .PRELIMINARY POINT TEMPS/POPS...

HEAVY RAIN. RISK...Limited. AREA...Eastern Oklahoma. ONSET...After 10 PM. DISCUSSION... Scattered thunderstorms had developed across parts of Northeast Oklahoma late this afternoon ahead of a thunderstorm complex developing to the west in Northwest Oklahoma. Scattered thunderstorms through the mid evening hours will remain possible mainly north of Interstate 40. An isolated severe potential with locally strong winds and hail will be capable within any thunderstorm development through the mid evening hours. Late this evening and into the overnight hours...the thunderstorm complex out west is forecast to move into Eastern Oklahoma and spread across the region into Northwest Arkansas. A limited severe potential will be possible across Eastern Oklahoma and Northwest Arkansas...though the greater potential continues to be over Eastern Oklahoma. Damaging winds of 60 to 70 miles per hour and quarter size hail will be the main threats through the overnight hours. Also...periods of heavy rainfall will again be possible tonight...which could increase flash flooding concerns especially over locations that have already received recent heavy rains. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Local Spotter Activation May Be Needed. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. TUESDAY...Thunderstorm Potential...Heavy Rain Potential. WEDNESDAY...Thunderstorm Potential. THURSDAY AND FRIDAY...No Hazards. SATURDAY AND SUNDAY...Thunderstorm Potential. EXTENDED DISCUSSION... Thunderstorms may be ongoing early Tuesday as a large storm complex is likely to be moving across the region. Instability across the region will allow for a continued severe potential Tuesday. The unsettled weather pattern will continue with thunderstorm chances Wednesday...however the trend will be for drier and warmer weather for late week. The next cold front is forecast to move into the region over the weekend with a chance of thunderstorms returning. weather.gov/tulsa contains additional information.
