Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 710 AM EST Mon Jan 05 2015 Valid 00Z Tue Jan 06 2015 - 00Z Tue Jan 13 2015 Today's guidance brings no major changes in the expected forecast with better than average clustering among individual model/ensemble mean solutions. A weak and fairly dry front will pass through the islands late Mon into Tue. Eastward progression of trailing high pressure should turn northerly winds more northeasterly by midweek, and then easterly later in the week. Expect low level flow to become southeasterly as the surface high becomes sufficiently distant and a front comes into the picture to the northwest of the region, on the southeastern side of a strong upper jet becoming established along 25-35N latitude. Any rainfall that occurs should be fairly light, especially around the middle of the week when GFS/ECMWF precipitable water values reach a minimum of 0.50-0.75 inch which would be 2-3 standard deviations below normal. Even though moisture should gradually increase from late week through the weekend, PWATs may still not reach much higher an an inch. Rausch
