VALID 00Z TUE JAN 24 2023 - 00Z TUE JAN 31 2023
A PERIOD OF LIGHTER WINDS WITH VARIABLE DIRECTION IS EXPECTED AS A
FRONT APPROACHES WESTERN AND CENTRAL ISLANDS BY TUESDAY. AFTER THE
FRONTAL PASSAGE, STRONGER NORTHEASTERLY FLOW WILL RETURN TO THE
STATE MIDWEEK, ESPECIALLY NORTHWEST OF THE BIG ISLAND. THERE WILL
ALSO BE AN UPTICK IN THE COVERAGE OF SHOWER AND THUNDERSTORM
ACTIVITY.
THERE CONTINUES TO BE A GROWING CONSENSUS FOR A CLOSED LOW ALOFT
TO FORM LATER IN THE WEEK AS THE AMPLIFYING TROUGH ASSOCIATED WITH
THE COLD FRONT MENTIONED ABOVE BUILDS SOUTHWARD TO AROUND 30
DEGREES NORTH. DEPENDING ON THE PROXIMITY TO THE ISLANDS THIS
FEATURE COULD INCREASE RAINFALL AND WIND SPEED.
