AN UPPER LEVEL TROUGH OVER THE MAINLAND AND ITS EMBEDDED CUT-OFF LOW  
OVER THE NORTHERN GULF PRODUCED A LARGE AREA OF RAINFALL OVER THE  
SOUTHERN MAINLAND AND ACROSS THE PANHANDLE... AND EVEN SOME SHOWERS  
ALONG THE EASTERN BROOKS RANGE. ENHANCED PRECIPITATION FROM  
SHORTWAVE ACTIVITY WAS MEASURED ALONG THE SOUTHERN SLOPES OF THE  
BROOKS RANGE AND CENTRAL ALASKA RANGE.  
 
THE LONG WAVE TROUGH FINALLY DEVELOPS INTO A SINGLE UNIFIED SYSTEM  
OVER THE EASTERN HALF OF THE MAINLAND BY FRIDAY AFTERNOON. THE SHORT  
WAVE ACTIVITY WITHIN THIS TROUGH WILL BE THE FOCUS OF ENHANCED  
PRECIPITATION THROUGH THE NEXT 48 HOURS AND REMAINS THE FORECAST  
DILEMMA. THE FIRST ONE TO CONTEND WITH WAS SWINGING THROUGH THE  
PANHANDLE DURING THE DAY ON FRIDAY AND THE NEXT ON IS SCHEDULED FOR  
SATURDAY AFTERNOON. A DEFORMATION SETTING UP ACROSS THE EASTERN  
MAINLAND WILL CONTINUE THE SHOWERS FROM SOUTHCENTRAL TO THE EASTERN  
BROOKS RANGE INTO SATURDAY.  
 
MUCH BETTER WEATHER WAS OCCURRING OVER MUCH OF THE WEST THANKS TO A  
RIDGE OF HIGH PRESSURE CENTERED OVER THE WESTERN ALEUTIANS.

BELOW NORMAL. ELEVATIONS RANGED BETWEEN THE SURFACE AT BARROW AND  
7500 FT AT KODIAK. FREEZING LEVELS BEGIN TO REBOUND FIRST OVER THE
