Re: one last hybrid

The feature HF and Allan have both now referred to is clearly "getting there" - it's a little surprising that an Invest tag isn't already up on this one. Up until this morning it appeared to be in the process of establishing a cold front, but since then it has taken on much less of a frontal appearance, and more of a classic symmetrical one. Phase diagrams have suggested that by tomorrow it may have become at least marginally warm-cored. What it has in symmetry however, it still lacks in convection, especially near and within the center, so that forecast might be a little bullish, at least initially.

As far as its future is concerned, it now appears to be heading westward, and staying far-enough south to continue traveling over SSTs in the 23-24+ C range. In some ways it is a little like pre-Olga, but with more frontal beginnings. 12Z runs nearly unanimously send it WSW or SW and weaken it substantially by next Wednesday, while over 25-26C waters, but unsurprisingly the CMC pretty much makes it a tropical storm, and keeps it heading west over the 23-25C range.

TAFB only had this to say about it at 1PM today
