DISCUSSION
 
 
AN UPPER LEVEL LOW OVER THE NORTHWEST GULF WILL LIFT NORTHWARD  
UP COOK INLET AND THE SUSITNA VALLEY TODAY. WIDESPREAD STEADY  
RAIN OUT AHEAD OF IT (FOR ALL BUT THE COPPER RIVER BASIN) WILL  
TRANSITION TO SHOWERS BY AFTERNOON. SHOWERS WILL THEN QUICKLY  
DIMINISH FROM SOUTH TO NORTH DURING THE EVENING HOURS AS THE  
UPPER LOW EXITS TO THE NORTH.  
 
A MUCH DRIER AND WARMER TREND WILL BEGIN TUESDAY AND CONTINUE  
THROUGH WEDNESDAY, WITH WIDESPREAD TEMPERATURES IN THE 60S  
EXPECTED WEDNESDAY AFTERNOON. LOW LEVEL OFFSHORE FLOW WILL  
ALSO LIMIT SEA BREEZES AND LEAD TO VERY LOW RHS INLAND (IN THE  
20S). WINDS, HOWEVER, WILL BE LIGHT WITH THE EXCEPTION OF A  
FEW GAPS WINDS ALONG THE COAST. KODIAK ISLAND WILL BE THE ONE  
EXCEPTION TO THE WARMING AND DRYING, WITH A MARINE LAYER EXPECTED  
TO MOVE IN TONIGHT OR TOMORROW AND LEAD TO COOLER AND CLOUDIER  
CONDITIONS.
