Increasing moisture and instability over the Eastern Interior
will bring heavy rain showers and widely scattered thunderstorms
Saturday and Sunday. The atmosphere over the weekend will be more
typical of late July than the end of May. Storms that do form 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.
It is possible that the heaviest rain will fall along the Alaska
Highway between Delta Junction and Tok Friday evening and again on
Sunday night into Monday morning. Rising freezing levels on
Sunday will allow snowmelt from high terrain above Cathedral
Rapids and Sheep Creek along the Alaska Highway to add to rainfall
in those streams. This may cause very high water in these streams
along the Alaska Highway.
Recreators should be alert for areas of heavy rainfall, lightning,
and for rapidly rising creeks and streams.
