NWS Forecaster Discussion




Area forecast discussion 
National Weather Service tiyan GU 
729 am chst Tuesday may 26 2015 


Synopsis... 
pgua Doppler weather radar shows only a few trade-wind showers 
moving through the marianas waters. The VAD wind profile reveals 
east-northeast winds of 3 to 7 knots through the lowest 3 thousand 
feet of the air. 


&& 


Discussion... 
weather to the east seems to be in no hurry to get here. Not too 
surprising with fairly low wind speeds noted on the VAD above. 
Winds could be favorable for island convection...however moisture 
is shallow as noted by a k-index value of 6. Therefore did not put 
anything in the forecast at this time. Day shift will need to 
review the morning sounding to see if there is sufficient 
moistening to make this a concern. Otherwise...starndard trade- 
wind showers and benign sea conditions will rule The Roost. 


&& 


Climate... 
latest enso diagnostic update from climate prediction center 
confirms that a weak El Nino continues. The marianas have had a 
wetter than normal dry season...micronesia is having a rather busy 
tropical cyclone season so far and Palau has been dry. Palau has 
received about 50 percent of its normal monthly rainfall so 
far...and 58 percent its normal rainfall for the year. If the 
deficit grows much larger we may need to start issuing drought 
statements. There appears to be little relief in the near-term. 
The gfs40 predicts less than half an inch the next 10 days while 
the European model (ecmwf)-hires predicts less than a quarter inch. The latest 
forecasts from the climate prediction center are for an 80 percent 
chance that this El Nino continues through the end of the year. 
The model plumes indicate it could grow from weak to moderate or 
even strong in that time. The European model (ecmwf) ensemble plume even hints at a 
chance this could be an extreme to record event. This is 
definitely a situation to monitor closely. 


&& 


Eastern micronesia... 
widespread showers and thunderstorms are seen near kwajalein and 
north to northwest of Majuro within a broad area of trade-wind 
convergence east of a surface trough. Satellite imagery has shown 
a slow backing trend with showers spreading eastward overnight. 
Short-term forecast at Majuro will need further watching...but for 
now...am expecting scattered showers to stay north of the atoll 
while a few thunderstorms are possible in northern waters of 
Majuro. Another weak trough will pass by Majuro around Wednesday 
night and should usher in drier conditions. Kosrae sits between 
showers and thunderstorms to the north and more to the south. A 
surface trough just east will pass through the area Wednesday. 
Models keep convection largely split to the north and south as the 
trough moves to the west. A weak low-level ridge will build into 
the area and bring drier weather by Wednesday night. Little change 
expected for Pohnpei. Weather pattern will remain slightly 
unstable as a trough approaches the area. More widespread showers 
are expected to stay to the north for the week but isolated 
thunderstorms are expected the next couple of days. 


&& 


Western micronesia... 
weak monsoon trough is drifting northward over Yap. Weak 
southwest winds at Koror will become variable... similar to Yap in 
the coming days. A weak wind flow and dry pattern is expected at 
both Yap and Koror through the week. Fairly quiet weather is 
expected at Chuuk through Wednesday. Isolated thunderstorms are 
expected later in the week as winds turn to the southeast as the 
weak circulation...now near 11n153e...moves westward. 


&& 


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