NWS Forecast Office Tulsa, OK

Shower and thunderstorm chances increase further on Wednesday as a cold front drops southeast into the region. Instability ahead of the front is expected to create a potential for severe storms across parts of eastern Oklahoma and northwest Arkansas. Large hail and damaging wind gusts are the primary hazards with any severe storm, but a low tornado threat will exist as well.

The best chance of severe weather, including large hail, damaging wind and a low chance of a tornado, Wednesday and Wednesday night will be from mid afternoon into mid evening to the southeast of a line from Eufaula to Jay. Morning storms to the north and west of that line may produce large hail.

Additional showers and thunderstorms are forecast to move into the region from the west late Thursday night and into Friday morning. There is a marginal risk of severe weather, primarily large hail and gusty winds, with this activity.

Shower and thunderstorm chances increase again Friday as another cold front pushes into the region. Instability ahead of the front could create a potential for severe storms across much of eastern Oklahoma and northwest Arkansas. Continue to monitor latest forecasts.

An unsettled weather pattern will persist for the remainder of this week and into the early part of the weekend. Periods of both a severe weather and heavy rain threat should be expected.
