NWS Forecaster Discussion




Area forecast discussion...added micronesian discussion 
National Weather Service tiyan GU 
605 PM chst Thursday Aug 21 2014 


Marianas synopsis... 
an elongated and extremely weak surface trough is evident on 
visible satellite imagery over the marianas. Winds were light west-northwest 
earlier on Guam and east-southeast on Tinian and Saipan...but winds have 
become light and variable in the last hour or two. Meanwhile...an 
upper-level low is seen in water vapor imagery centered around 
12n151e...moving west. 


&& 


Discussion... 
models show the weak circulation breaking down overnight into a weak 
trough on Friday...while the westward-moving upper low opens into a 
trough as it passes over the islands on Friday. With adequate 
moisture still in the mid-levels...this is enough to keep isolated 
thunderstorms in the forecast tonight...and have extended them 
through Friday as the upper trough moves by and island heating with 
light winds provides an extra boost. The rest of the forecast 
remains the same as previous...partly cloudy skies and isolated 
showers--unusually dry for August. 


&& 


Eastern micronesia... 
a surface trough running from about 11n165e to 1n154e is weakening 
as it moves westward. The models indicate high pressure is building 
just east of the trough for a short while until other troughs move 
in at intervals behind it. Tonight at Majuro there is a surface 
trough just to the east followed by a convergence zone. The models 
show the convergence zone and weak troughs affecting Majuro after 
tonight. This evening Kosrae is on the trailing edge of cloud cover 
around the weakening trough with a ridge to the east. The models 
indicate the ridge will affect Kosrae Friday and Friday night...then 
weak troughs and weak ridges will follow. Pohnpei is experiencing 
the weakened trough then followed by additional weakening Friday 
with ridging to the south. 


&& 


Western micronesia... 
no major changes to the inherited forecast for western micronesia. 
The monsoon trough north of 10n continues to be the primary weather 
influence over the region. Mainly light winds are expected across 
the region. Chuuk is on the edge of cloud cover with thunderstorms 
nearby to the west. What follows at Chuuk will be weather similar to 
Pohnpei. Yap is in an area of convergence between high pressure to 
the south and a circulation to the northeast. A ridging pattern is 
expected to be near Koror through the weekend.

Gum watches/warnings/advisories... 
GU...none. 
Marianas waters...none.
