DISCUSSION
HIGH PRESSURE SOUTH OF THE ALEUTIAN CHAIN AND LOW PRESSURE OVER
THE YUKON TERRITORY WILL KEEP WESTERLY WINDS AND AREAS OF PATCHY
FOG OVER NUSHAGAK BAY THROUGH TONIGHT. ON THURSDAY A TROUGH OF LOW
PRESSURE WILL MOVE THROUGH THE STATE FROM THE SEWARD PENINSULA TO
INTERIOR SOUTHWEST ALASKA. THIS WILL INCREASE SOUTHWESTERLY WINDS
AND GENERATE RAINFALL BY THURSDAY AFTERNOON. GUSTS AROUND 25 KT
CAN BE EXPECTED TOMORROW AFTERNOON AND EVENING AS THE FRONT MOVES
THROUGH. WESTERLY WINDS THROUGH TOMORROW WILL LIKELY YIELD A
LIMITED SEA STATE DUE TO THE PROTECTION OF CAPE CONSTANTINE, BUT
WAVES IN THE OUTER BAY ARE LIKELY 1-2 FEET THROUGH TOMORROW
MORNING AND UP TO 3 FEET TOMORROW AFTERNOON AND EVENING AS THE
WINDS SHIFT AND STRENGTHEN.
