SEVERE THUNDERSTORM. RISK...Limited. AREA...Eastern Oklahoma and Northwest Arkansas. ONSET...Ongoing. HEAVY RAIN. RISK...Limited. AREA...East Central and Southeast Oklahoma and Northwest Arkansas. ONSET...Ongoing. DISCUSSION... Strong to severe thunderstorm activity that developed across much of the region this afternoon has shifted into northwestern Arkansas and has gradually weakened. Pockets of gusty outflow wind will be possible with the stronger storms through this evening. Additional thunderstorm development is expected across primarily east central and southeastern Oklahoma, as well as northwestern Arkansas late this evening and overnight. Some of this activity will pose the threat for additional locally heavy rainfall, which could result in localized flooding, and gusty wind. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Local Spotter Activation May Be Needed. .DAYS TWO THROUGH SEVEN...Monday through Saturday. MONDAY...Thunderstorm Potential...Heavy Rain Potential. TUESDAY...Severe Thunderstorm Potential...Heavy Rain Potential. WEDNESDAY...Thunderstorm Potential. THURSDAY through SATURDAY...No Hazards. EXTENDED DISCUSSION... A fairly strong upper-level system will approach the area from the northwest Monday night and Tuesday. With that will come the possibility for one or two storm complexes that should be more robust than the recent systems. If this setup evolves as current data suggests, a more widespread swath of 3 to 5 inches of rain could occur from Monday night into Tuesday night, with local multi-day totals approaching 7 inches. These amounts would drive a threat for more than local flash flooding and some river flooding. Current data favor northwest Arkansas and adjacent portions of far eastern Oklahoma for the heaviest rain potential, but this could easily shift a number of counties in any direction at this point. EMERGENCY MANAGEMENT PLANNING STATEMENT... Emergency managers and area responders should monitor the latest information for Monday night and Tuesday. Given recent rains in some areas, and the potential for excessive rains from Monday night into Tuesday night, preparations for more widespread flooding issues may need to happen on Monday. weather.gov/tulsa contains additional information. 69
