00z FV3 is a hit. It digs the wave, then separates it from the northern stream before rounding the base of the trough and going negative tilt through the Carolinas. It manages to be just cold enough on the NW side in spite of disconnecting from the northern stream
Agree it was a better run on the GFS. 18z FV3 looks pretty good at h5 with the wave, but it struggles to throw precip inland. It was a good run for RDU area, though sfc temps may be sketchy.
UKMet on left / Euro on right at hr144 (at end of UKMet run). Largely similar for a day 6 map. Euro is a little more relaxed with the height field along the east coast, allowing the wave to get to neutral and spin up a good storm after this point.
Euro Ens Mean shows some slight improvement. West coast ridge is a little taller and the wave digs south a little more. More signal for the sfc low off the SE coast. The 51 member mean will move in baby steps - to be expected.
Think you'd do a little better than it shows, but as depicted, it's a bit of a late bloomer where the system can't draw in moisture from its southeast and generate precip until the trough gets to neutral tilt.
Could be a fun event to track...east of the mtns we need the Friday arctic boundary to do its job to usher in the cold and push the baroclinic boundary down into the northern gulf
New 12z FV3 is close to the ICON look. It has a nice backside wave that dives down into the conus trough into New Mexico, then along the gulf coast with sfc low from NE gulf to off the SE coast. It doesn't quite turn the corner and pump good precip inland
12z ICON has a healthy wave diving way south into the gulf at the end of the run Sun night. Hard to say how much it would turn the corner and pump precip inland as the wave is a bit positive tilt, but I'll take that look for sure at this juncture.
00z CMC was amped and on the warm side. The new 12z run is chilly, but weak and off the coast with the low
Yeah Orangeburgwx, I wouldn’t get trigger happy with this one. Give it a couple more days to see if there is more of a concensus. 5 days with multiple model support is a solid rule that we have. Just my opinion
