Area Forecast Discussion
National Weather Service Tiyan GU
346 PM CHST SAT MAY 28 2016

.Synopsis...
Light winds and strong solar heating of the island resulted in
island thunderstorms this afternoon over western Guam and the
offshore waters to the west. Radar indicates the storms are now
weakening...but other island showers are popping up over northern
Guam. Elsewhere in the Marianas...showers are very isolated.

&&

.Discussion...
Overall...the forecast is basically unchanged. The only issue is
the chance for more island thunderstorms over Guam Sunday
afternoon. Winds will again be light...but moisture will be
decreasing during the day and may only support moderate island
showers rather than the heavy thunderstorms seen today.

&&

.Fire weather...
Light winds will reduce the danger of Red Flag conditions over the
island next few days.

&&

.Eastern Micronesia...
A few showers are seen south and west of Pohnpei while more showers
are present across the central Marshall Islands and eastward to
the dateline. Scattered showers will spread over Majuro tonight
and linger through Monday before this area of convergence shifts
west. Kosrae will see isolated showers and thunderstorms by Sunday
night. Models show the zone of trade-wind convergence centered
near Kosrae but the shower coverage is a little more diffuse by
Sunday night and Monday. Pohnpei will see increasing cloudiness
and a slight chance of thunderstorms early next week.

&&

.Western Micronesia...
Quiet weather conditions persist across much of the region with some
showers seen northwest of Yap and Koror and near Chuuk. The
subtropical ridge remains just north of Yap over the Philippine Sea
and an upper-level trough curves eastward from Yap to south of the
Marianas. Divergence aloft is helping to trigger short-lived
thunderstorms in the area northwest of Yap and Koror but convection
remains isolated. With no large scale features expected to develop
across the region...very few changes were needed to the inherited
forecast. Light winds at Koror could set the stage for afternoon
thunderstorms the next day or two.

&&

.GUM Watches/Warnings/Advisories...
GU...None.
Marianas Waters...None.
