Windspeed

Strong backside winds should be hitting the Sarasota metro and all of the coastal communities south along the shoreline now.

RE: Punta Gorda and Port Charlotte surge...

Surge starting to move into Venice...

Should be new low pressure records by Milton for many of these communites. https://www.twitter.com.com/DRmetwatch/status/1844170494200959046?t=s-4X4kBTGpS6uLJioL3dIQ&s=19

RE: Sustained winds and gusts enhanced by the low-level jet. This region should be quite fierce through the night post-landfall as transition continues. I do believe this will orient itself to bring the highest wind perpendicular into Sarasota, Laurel, Venice, and North Port on the southern semicircle of the circulation where the worst will be seen for surge impacts. This will, unfortunately, coincide with higher tide.

Be cautious of idiots reposting tornado videos on SM from old tornado outbreaks. I just got fooled myself.

As bad as the inland tornado outbreak has been, I'm afraid the surge is still going to be the biggest disaster with Milton. Most of us knew the timing of landfall would coincide with a degraded core and transition, but the sea heights aren't just going to magically disappear. Sea height and fetch has already been acquired, and areas south of the circulation will be inundated. We don't need a thick/intense southern eyewall band either. Strong surface winds perpendicular to the peninsula shoreline will be aided by the low-level jet to push the fetch onshore south of Milton's circulation center. The surge threat is high for a reason regardless of landfall intensity and why evacuations were needed.

The HAFS models have been excellent simulating the interaction with front, trough, mid-to-upper jet, and its transitioning evolution with these features. Milton's current structure at this point just prior to landfall is very similar to their simulated structures for several days runs. Now we watch for the SLP enhanced surge aided by the expanding windfield. We also watch for Milton's southern circulation to be aided by the ST jet and potential sting jet driven westerly winds, which may enhance low-level winds in shoving the surge on the shelf inland.

Dropsonde was 910 mb at 14 kts.

EXTRAP 912.6 mb

Since Key West Radar is just barely picking up the eastern eyewall, here is a zoom in of the last 15 scans or so from the radar out of La Bajada, Cuba. Here is the most recent scan. Not at PC and my phone is being a pain to upscale the gif resolution, so here...

lol.. This hits too close to home.

It looks like the strong eastern outer band from earlier this evening has merged with the eastern eyewall, and now we have a large feeder spiraling around from the NW into the southern semicircle of a dominant eyewall. Perhaps it was a partial EWRC or just a merger, but recent recon is no longer finding a double wind maxima that is concentric. As such, Milton may begin restrengthening again through the morning hours. The CDO has actually cooled again the past few hours, and the eye is warming as well..

SW quadrant of the CDO might have trended warmer briefly, but cloudtops are cooling again. Here's both AVN and enhanced colorized for your eyes.

Even without waiting on recon, the NHC could easily re-upgrade Milton to Category 5 for the 4PM CDT/5PM EDT advisory. Though recon is descending to operational altitude, the forecaster has all of the satellite intensity estimate support to at least bump it up to 160-165. ADT supports ~150 kts even if they went much more conservative than that.

I don't know if this was shared yesterday or last night, but to say Milton's high-end intensity on an eastward motion is anomolous is quite an understatement. It would have been an anomaly as a Category 4. But for it to have attained Category 5 while moving ESE had never been seen before in HURDAT records.

Here is the most recent profile of GOM SSTs. Consider that Milton is currently reintensifying over a shallow shelf north of the Yucatán where immediate shallow layer SSTs are still ~29°C. Milton's core will move over regions of 30°C and slightly higher several times prior to landfall. Though there had been a PRE and a lot of storminess over these areas the past 24-36 hours, the thermal content near the surface simply isn't going to be an issue for Milton. It's the atmospheric dynamics at play and Milton's internal evolution of structure that will dictate its landfall intensity.

Based on the projected forward motion of Milton as it crosses the eastern GOM, the loop current is kind of an overrated feature. It's not going to be moving slow enough that depth of 26°C isotherm really matters. SSTs are pretty much 29°C near the surface for the remainder of its track and pushing 30°C over the shelf west of the Florida shoreline.

Eye continues to clear as evident in the ongoing temperature spike within the eye.

Nice post by Webb on Milton's structural evolution, EWRC overnight, and vorticity merger.

There's not really much to add. The evolution of Milton's structure over the past three hours speaks for itself. The next recon flight should be interesting.

Interesting maneuvering by recon on this last pass.
