...DRY AND CLEAR CONDITIONS INTO THE BEGINNING OF THE WEEKEND...
...BREEZY CONDITIONS ACROSS THE NORTHERN IDAHO FORESTS SATURDAY AFTERNOON...

.DISCUSSION...Clear and dry conditions today and into the beginning
of the weekend under a west-northwesterly flow aloft. A weak dry
cold front will move across the region Saturday afternoon for
increased winds, mainly across the northern Idaho forest
districts. Look for RHs 15 to 20% and gusts to 20 mph across zones
402 and 403. Winds aloft will shift to the southwest Sunday and
Monday, allowing moisture to reach the Nevada border, however,
conditions will be drier than expected. The incoming trough for
Tuesday and beyond, has slowed, with the main thunderstorm threat
reaching all zones Wednesday.
