NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Honolulu HI 
1000 am HST Monday Jul 28 2014 


Synopsis... 
high pressure far northeast of the state will maintain moderate to 
locally fresh trade winds across the islands. Showers carried by the 
trades will affect mainly windward and Mauka areas for the next 
several days. A surge in moisture from the southeast could bring an 
increase in showers and more humid conditions late in the week. 


&& 


Discussion... 
water vapor imagery shows an upper level trough north of the 
state...with a ridge to the southeast. At the surface...high 
pressure is located far northeast of the state...with a trough far 
to the north. 12z soundings from Lihue and Hilo show inversions of 
5-6kft and precipitable waters of 1.3-1.4 inches...which is normal 
for this time of year. Early morning mimic total precipitable water 
imagery shows drier air over 100 miles east of The Big Island 
extending well to the east and northeast. 


Rainfall amounts have been on the low side overnight. A few 
locations on windward Big Island received up to a tenth of an inch 
of rain in the last 12 hours...but most locations that saw rain only 
received a few hundredths. One more pocket of moisture is located 
east of The Big Island and Maui that will keep showers going into 
early afternoon...at least across the eastern islands. However drier 
low-level air will spread across the state during the 
afternoon/evening...leading to drier conditions later in the day. 


The surface high will remain nearly stationary far northeast of the 
state through much of the week. While the high does not 
strengthen...we are already starting to see a tightening of the 
pressure gradient across the islands due to low pressure well to our 
south. Overall we expect a typical trade wind setup with showers 
focused mainly across windward and Mauka areas...at least for the 
first half of the week. GFS forecast soundings show inversion 
heights dipping even lower for the next day or two. With no 
noticeable sources of moisture immediately upstream...this will help 
to limit rainfall chances for the next couple days. Winds may be 
locally breezy at times. 


By the end of the week...we may see a surge in tropical moisture 
from the southeast that could bring an increase in showers and muggy 
conditions. Extended models over the last few days have been back 
and forth with timing and how far north to bring the moisture...so 
it is difficult to nail down specifics at this point. However...they 
seem to be converging on a solution that would bring an increase in 
tropical moisture to Big Island late Thursday/Friday...and spread 
across the rest of the state through the weekend. 


&& 


Aviation... 
morning showers linger over windward Big Island...bringing tempo 
MVFR ceilings and isolate MVFR visible to phto. VFR should begin to prevail by 
this early this afternoon for windward Big Island. All other 
terminals continue with prevailing VFR conditions. Passing showers 
embedded within the trade wind flow may bring isolate MVFR ceilings 
throughout the day...mainly for windward and Mauka areas. 


Early morning soundings from both sites show an inversion between 
5.5-6.5 kft. With the moderate trades expected to increase slightly 
and the inversion...an airmet for turb in the Lee of the terrain may 
be necessary later today. Otherwise...no other airmets are expected. 


&& 


Marine... 
an ascat pass last night showed a wide area of 25 knot winds through 
the Alenuihaha Channel. Models show the gradient continuing to 
tighten over the next couple days as low pressure passes far south 
of the area. Therefore the current Small Craft Advisory for the 
typically windier areas near Maui and The Big Island will likely 
remain in effect at least through Wednesday. 


A series of small southerly swells may bring minor bumps on south 
facing shores...with a slight increase on Thursday night. Short 
period trade wind swell will continue across east facing shores... 
possibly increasing a bit in the coming days as trades strengthen. 
No other significant swells are expected through the next several 
days. 


&& 


Hfo watches/warnings/advisories... 
Small Craft Advisory until 6 PM HST Wednesday for Maalaea Bay- 
pailolo and alenuihaha channels-Big Island leeward and southeast 
waters.
