.DISCUSSION...
Gusty southerly winds through Copper River are expected this
afternoon and should decrease this evening. High temperatures
within the Copper River Valley and Basin will approach the mid 70s
this afternoon with RHs not expected below 40 percent. Cool air
will follow behind a front that is moving from west to east and
daytime highs Friday afternoon will be about 10 degrees cooler.
Scattered showers will be possible with the frontal passage and
while there is some atmospheric instability, chances for isolated
thunderstorms will likely be inhibited due to cloud cover. But, if
enough clearing occurs early enough in the day Friday, a
lightning strike or two is possible near the Tok Cut Off and
eastern Alaska Range.
