A low chance for thunderstorm development from late afternoon Monday into Monday evening exists, with environmental conditions supportive of high impact weather with storms that develop. Very large hail and damaging straight line winds will likely be threats with the strongest storms that develop. A limited tornado threat will exist, as well. Continue to monitor forecasts and be prepared to take action if severe weather threatens your location.
Severe weather potential will continue during the day Tuesday and perhaps into the evening also. Large hail, damaging winds and heavy rain are the favored threats Tuesday, with a lower chance of tornadoes than expected on Monday. Continue to monitor forecasts and make sure your severe weather communications and sheltering plans are ready to go.
Multiple rounds of showers and thunderstorms Tuesday into Wednesday night will increase the threat for flash flooding across the region. Widespread rainfall totals from 2 to 4 inches, with local totals to 8 inches, are expected, leading to a Moderate Risk of flash flooding. In addition to flash flooding, a medium chance for mainstem river flooding exists. Continue to monitor forecasts and remain alert for warnings. Always remember to turn around, don't drown and seek higher ground if flooding threatens your location. If you have interests along area rivers, keep an eye on river forecasts and be prepared to take action to protect those interests.
The potential for severe thunderstorms will linger into Wednesday across much of eastern Oklahoma and all of western Arkansas, although the better chance for severe weather will be located just south of the Red River.
