...SHOWERS IN THE IDAHO FORESTS THROUGH FRIDAY...
...NEXT WETTING RAIN THURSDAY NIGHT/FRIDAY IN SOUTHERN AREAS...
.DISCUSSION...Showers this afternoon and tonight over higher
terrain. Also isolated thunderstorms through this evening
in the Payette and Boise NFs. Showers should continue in
northern areas through Friday. Cold front along the coast
will weaken as it comes inland tonight, but will still be
strong enough for showers over higher terrain in our
district. Main upper low off the northwest coast will
become stronger Thursday leading to formation of a new cold
front from northern Nevada through eastern Idaho and another
rain event along the cold front late Thursday night through
Friday. This will be followed by cooler air over the
district, with snow showers over highest Idaho mountains
Friday through Saturday. Northern valleys should stay moist
enough for morning fog through the week.
