Hazardous Weather Outlook National Weather Service Tulsa OK 1237 PM CDT Thu Apr 20 2023 ARZ001-002-010-011-019-020-029-OKZ049-053>076-211015- Adair OK-Benton AR-Carroll AR-Cherokee OK-Choctaw OK-Craig OK- Crawford AR-Creek OK-Delaware OK-Franklin AR-Haskell OK-Latimer OK- Le Flore OK-Madison AR-Mayes OK-McIntosh OK-Muskogee OK-Nowata OK- Okfuskee OK-Okmulgee OK-Osage OK-Ottawa OK-Pawnee OK-Pittsburg OK- Pushmataha OK-Rogers OK-Sebastian AR-Sequoyah OK-Tulsa OK-Wagoner OK- Washington OK-Washington AR- 1237 PM CDT Thu Apr 20 2023 This Outlook is for Northwest and West Central Arkansas as well as much of Eastern Oklahoma. .DAY ONE...This Afternoon and Tonight. TORNADO. RISK...Limited. AREA...Southeast Oklahoma and West Central Arkansas. ONSET...Ongoing. SEVERE THUNDERSTORM. RISK...Elevated. AREA...Eastern Oklahoma and Northwest Arkansas. ONSET...Ongoing. HEAVY RAIN. RISK...Limited. AREA...Southeast Oklahoma and West Central Arkansas. ONSET...Ongoing. SIGNIFICANT WINDS. RISK...Limited. AREA...Eastern Oklahoma and Northwest Arkansas. ONSET...Ongoing. FIRE WEATHER DANGER. RISK...Limited. AREA...Northeast Oklahoma, west of Highway 75. ONSET...Ongoing. DISCUSSION... A cold front will continue moving through the region today, with scattered strong to severe storms likely along the front across southeast Oklahoma and northwest Arkansas. The stronger storms will be capable of producing large hail and damaging winds, including a tornado or two. The severe weather threat will end by late afternoon or early evening as the front sweeps southeast of the region. Gusty northerly winds and a much drier air-mass will at least lead to a limited fire weather threat this afternoon across northeast Oklahoma, mainly west of Highway 75 where min RH values will drop into the 20-30 percent range. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Activation of the Regional Spotter Network Likely. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. FRIDAY...Very High Fire Weather Potential. MONDAY...Thunderstorm Potential. TUESDAY AND WEDNESDAY...Thunderstorm Potential...Heavy Rain Potential. EXTENDED DISCUSSION... Cooler weather will follow the front tomorrow and through much of the rest of the forecast period. The lighter winds and cooler temps should help limit the fire weather threat a little, though much drier air behind the front tomorrow will cause afternoon RH values to drop into the 20-30 percent range west of Highway 75 in northeast Oklahoma. Rain chances return on Sunday for southeast Oklahoma and for the rest of the forecast area much of the beginning of next week. Heavy rain/flooding could become a concern as multiple rounds of showers and storms appear possible. Severe weather chances appear to be limited at this time. weather.gov/tulsa contains additional information.
