Rather quiet pattern to start the week will get interrupted on
Wednesday as a weak cold front pushes through the northern
islands. This should attempt to move through the rest of the
island chain on Thursday but its support will move off to the
east, leaving it to dissipate. Modest high pressure in its wake
should veer winds from northerly post-frontal passage to brisk
northeasterly late Thursday into Friday. ECMWF ensembles indicate
more precipitation for the Big Island Friday compared to the GEFS
members, which is possible but PW values should gradually drop
below climo values (1.2" or so at Hilo). Upper ridging will then
build into the region this coming weekend per the latest ensemble
guidance.
