Leftover moisture with an old boundary will support some local
enhancement to tradewind showers the next couple of days. An upper
trough is forecast to dig southward along 160W to 150W through the
mid-latitudes which will drive the tail-end of a cold front into
the region around Thu. Rainfall may focus in a narrow convergent
zone across some of the islands but precipitable water values may
only increase to around 1.25 inches except perhaps near 1.50
inches over the Big Island as the weakening boundary slips a bit
farther south. Model consensus is preferred. Typical trade pattern
may again resume by next Mon into Tue with high pressure to the
NNW of the area moving eastward but weakening.
