Special Weather Statement issued May 25 at 9:56AM AKDT by NWS Fairbanks AK
Increasing moisture and instability over the Eastern Interior will bring heavy rain showers and widely scattered thunderstorms through Monday. The atmosphere over the holiday weekend will be more typical of late July than the end of May. Storms that do form today will not move quickly and may be nearly stationary, which will allow them to drop abundant rainfall over small areas. Not all areas will see rainfall, but creeks and streams near areas that do see heavy rain may rise rapidly, especially in steep terrain. By Monday, the bigger threat from these thunderstorms will be strong outflow winds, abundant

As they fall apart, also expect the potential for brief strong and gusty, erratic winds. In addition, locally heavy rain amounts are possible over the Western and Central AK Range with a
