.SYNOPSIS...
WEAK HIGH PRESSURE WILL BRING MAINLY DRY CONDITIONS TO THE INLAND
NORTHWEST TONIGHT THAT WILL ACCOMPANY AN INCREASING FOG THREAT. THE
FOG WILL BE DENSE AROUND THE LEWISTON AREA EARLY THIS EVENING. FOLLOWING
THE PASSAGE OF A FRONTAL BOUNDARY THAT WILL PRODUCE SOME LIGHT
MOUNTAIN SNOWS FOR NORTH IDAHO AND NORTHEAST WASHINGTON THIS
WEEKEND...A WEAK FRONTAL SYSTEM MAY BRING SOME LIGHT PRECIPITATION
TO THE REGION MONDAY NIGHT INTO TUESDAY. THE REMAINDER OF THE WEEK
SHOULD BE CHILLY...BUT DRY.

.DISCUSSION...

WE'VE MADE UPDATES TO THE FCST FOR THIS EVENING AND TONIGHT THAT
INCLUDED ENDING THE DENSE FOG ADVSY FOR THE CAMAS PRAIRIE AND
LEWISTON REGION...DECREASING THE FOG THREAT SUBSTANTIALLY FOR ALL
BUT THE PALOUSE AND LEWISTON AREA...AND COOLING LOW TEMPS
OVERNIGHT. THE RATHER DRY AIRMASS THAT HAS MOVED INTO THE AREA
BEHIND THIS MORNINGS COLDFNT HAS ALLOWED US TO DECREASE THE FOG
POTENTIAL WELL INTO SAT AS WELL. BZ

.AVIATION...
DRY AND RATHER CLEAR CONDITIONS WILL CONTINUE TO DOMINATE MOST
SITES THROUGH THE NIGHTTIME HOURS. HOWEVER...A BANK OF STRATUS
NEAR KPUW WILL GRADUALLY ERODE AND MOVE NORTHWARD THROUGH 10Z.
THIS MAY MAKE IT AS FAR NORTH AS JUST SOUTH OF KGEG BEFORE
GRADUALLY DISSIPATING TOWARD MORNING. OTHERWISE...SOME RADIATION
FOG IS POSSIBLE IN SHELTERED LOCATIONS OVERNIGHT. THE NEXT SYSTEM
COMES IN SATURDAY AFTERNOON...GENERALLY CAUSING -SN NORTH AND
EAST OF KGEG. /FRIES
