IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
A SHALLOW MARINE LAYER BELOW WARM AND DRY AIR WILL BRING SIGNIFICANTLY
DIFFERENT CONDITIONS FOR ELEVATIONS BELOW 500 FEET COMPARED TO THE
REST OF THE ISLAND. NORTHWEST WINDS WILL BRING INCREASING OVER THE
NEXT COUPLE OF DAYS IN GENERAL, BUT TIMING AND WIND SPEEDS WILL NOT
BE UNIFORM ACROSS THE ISLAND. THE LACK OF OBSERVATIONS ALSO MAKE IT
CHALLENGING. ALL OF THESE FACTORS WILL BRING LOWER CONFIDENCE IN
THE FORECAST THAN USUAL. MODERATE CONFIDENCE IN IMPROVED HUMIDITIES
ON THURSDAY, BUT STILL LOWER THAN USUAL FOR MAY. MORNING WINDS WILL
BE GENERALLY LIGHT BUT SOMEWHAT ERRATIC. THE NORTHWEST WIND SHIFT
WILL LIKELY BE LATER ON THURSDAY THAN TODAY.
