NATIONAL WEATHER SERVICE ANCHORAGE AK
752 AM AKDT MON MAY 4 2026
FORECAST IS BASED ON IGNITION TIME OF 0900 AKDT ON MAY 04.
DISCUSSION
A LOW PRESSURE SYSTEM IN THE NORTH PACIFIC WILL CONTINUE TO MOVE
NORTH TODAY, BRINING LIGHT RAIN THROUGH MIDDAY. THE APPROACHING
STORM SHOULD DRAW VERY LIGHT NORTHEAST WINDS OVER THE AREA TODAY,
WHICH WILL LIKELY CONTINUE OVERNIGHT. TOMORROW, LOWER PRESSURE
WILL DEVELOP INLAND HELPING TO SHIFT THE WIND DIRECTION TO BE MORE
SOUTHERLY TO WESTERLY, BUT REMAINING VERY LIGHT. COLDER AIR
MOVING IN ALOFT ON TUESDAY MAY PROMOTE SOME SHOWER ACTIVITY LATE
TUESDAY AFTERNOON BUT CONFIDENCE IS LOW ON WHETHER SHOWERS WILL
DEVELOP OVER THE BURN AREA. PRECIPITATION LOOKS MORE LIKELY TO
RETURN LATE TUESDAY NIGHT AND INTO WEDNESDAY.
