Hawaii Extended Forecast Discussion...Corrected NWS Weather Prediction Center College Park MD 228 PM EST Wed Feb 25 2015 Valid 00Z Thu Feb 26 2015 - 00Z Thu Mar 05 2015 The 25/00Z forecast cycle of the ECENS/ECMWF, GEFS/GFS and NAEFS seemed to be in decent agreement through the entire forecast period---though there are some subtle differences aloft on or just after 3/00Z. Concerning the 'Kona-like' upper system along 15N 140W, the latest guidance has not made many changes---allowing the feature to make its closest approach to the Big Island around 27/12Z---then have mid-level ridge to its north and the frontal boundary to its west---effectively 'blocking' its westward migration after 27/12Z. For the latter half of this forecast period, recommend a blend of the 25/00Z GEFS/ECENS/NAEFS. This would make for a slightly more-amplified flow pattern across the Pacific---but a slower west-to-east progression of the low-level front across Hawai'i this weekend and early next week. Vojtesak
