NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Honolulu HI 
846 PM HST Friday Jul 25 2014 


Synopsis... 
moderate trade winds will focus showers mainly across windward 
and Mauka areas. An increase in shower activity is expected to 
move from east to west across the state during the weekend. 
Trades may strengthen somewhat early next week. 


&& 


Discussion... 
a quiet late July evening is in progress across the state. Radar 
loops and rain gauge data show passing trade showers across some 
windward areas...with rainfall accumulations generally remaining 
on the light side. A typical summertime surface pattern prevails... 
with the northeast Pacific high centered about 1400 miles 
northeast of Honolulu. A weak low pressure area is located about 
720 miles south southeast of South Point on The Big Island...and 
is being monitored for signs of development while moving to the 
west. Water vapor imagery depicts a middle level ridge extending 
from The Big Island eastward...with an upper level trough located 
several hundred miles northeast of Kauai. The 00z soundings show a 
well defined inversion based around 7000 feet...with near normal 
precipitable water values of between 1.3 and 1.4 inches. Mimic-tpw 
imagery shows an area of higher moisture (pwats 1.5 to 1.7 inches) 
approaching the state from the east...with the leading edge about 
100 miles southeast of The Big Island. 


Through the overnight...would expect trade showers to increase 
across windward areas in the typical manner...with a few of the 
showers spilling over into some leeward areas. The highest rain 
chances should occur across windward slopes of The Big Island and 
Haleakala...as the area of enhanced moisture moves in late 
tonight. The existing forecast reflects the above thinking... 
and no updates are planned for this evening. 


Little change is expected to the overall moderate trade wind 
pattern through the weekend. Models appear to initialize the 
area of higher moisture currently just east of the state 
reasonably well...and move this area steadily westward through 
Sunday. During this time...the upper level trough initially 
northwest of Kauai will move eastward...passing north of the state 
Sunday and Sunday night. Would expect the trade inversion to rise 
and weaken a bit in response...which combined with the additional 
moisture moving through could produce a few locally heavier 
showers at times. Persistent moderate trade flow should keep the 
showers moving along however. Probability of precipitation will remain quite high over 
windward and Mauka sections especially during the night and early 
morning hours...with some spillover into leeward sections of the 
smaller islands. 


Heading into next week...the northeast Pacific high is forecast 
to weaken somewhat as a cold front moves eastward north of 
30n...but at the same time a tropical low passing well south of 
the state may be able to maintain or even tighten the pressure 
gradient locally. Overall would expect a typical trade wind 
pattern to prevail for Monday through at least Tuesday...with 
passing showers mainly affecting windward and Mauka. 


Toward the middle to later part of next week...some of the model 
guidance continues to bring another surge of deep tropical 
moisture up toward the state from the southeast. This moisture 
would be associated with the remnants of current east Pacific 
Tropical Storm Genevieve. The guidance suite has been rather 
inconsistent with both the timing and extent of any possible 
moisture surge. There is the potential for another round of 
heavy showers across the state later next week and into next 
weekend...but forecast uncertainty remains quite high at this 
point. 


&& 


Aviation... 
tempo MVFR conditions will likely occur this evening through 
Saturday morning...mainly over windward and Mauka sections...as 
low clouds and accompanying showers ride the trade winds. VFR will 
otherwise predominate. 


&& 


Marine... 
there is no recent ascat data available across the Hawaiian 
coastal waters...but an earlier ascat pass across the western 
waters and current mesonet data imply that winds are likely below 
Small Craft Advisory /sca/ criteria throughout the area. The 
northeast Pacific surface high will move slightly further away 
from the state during the weekend...but a low pressure area 
passing well south of the area may tighten the gradient across 
the islands somewhat. Winds may increase to Small Craft Advisory levels as early 
as Sunday evening across the typically windier areas around Maui 
County and The Big Island...but this remains uncertain. Small Craft Advisory 
conditions will remain possible in the typically windy areas 
through much of next week. 


As for surf...a small south-southwest swell may produce a minor bump on south 
facing shores Saturday night and Sunday. Short period trade wind 
swell will continue across east facing shores...possibly 
increasing a bit early next week if trades strengthen. No 
significant north through west swells are expected through the 
next several days. Overall...surf will remain well below advisory 
levels on all shores through the weekend and into the first part 
of next week.
