ZONES. THE FRONT ASSOCIATED WITH THE DEEP LOW LOCATED NEAR THE
KAMCHATKA PENINSULA IS STRETCHED OUT THROUGH THE WESTERN BERING
ACROSS THE CENTRAL ALEUTIANS.  IT WILL MAKE LITTLE PROGRESS EAST AS A
SERIES OF LOWS DEVELOP ALONG IT. EXPECT MOSTLY SNOW SHOWERS OVER THE

OF LOW CLOUDS AND FOG. THE COLD AIR MASS OVER THE SOUTHERN INTERIOR
