Textbook core coming together quickly. Perfect anti-cyclone overhead.
PV anomaly still mid-level, hasn't gotten down to the surface yet.
Plenty of potential to spin up deep.

Looks a good deal stronger than the JWTC estimatedf, at leasty as of last night...
Probably undergoing some sort of RI at the moment based on its great presentation.

Re: WPAC: MA-ON - Severe Tropical Storm
Hate to say this, but this is looking bad for spreading Fukushima radiation over Honshu.
Already heard they are selling radioactive beef there.

REMARKS:
130900Z POSITION NEAR 19.8N 150.8E.
TROPICAL STORM (TS) 08W, MA-ON, LOCATED APPROXIMATELY 650 NM
EAST-SOUTHEAST OF IWO TO, JAPAN, HAS TRACKED WEST-NORTHWESTWARD AT
13 KNOTS OVER THE PAST SIX HOURS. ANIMATED SATELLITE IMAGERY SHOWS
STEADY DEVELOPMENT AND ORGANIZATION OVER THE PAST 24 HOURS.
CONVECTION HAS CONSOLIDATED NEAR THE LOW LEVEL CIRCULATION CENTER
(LLCC) AND FILLED IN THE SOUTHWESTERN QUADRANT OF THE SYSTEM, WHICH
WAS RELATIVELY CLOUD-FREE 24 HOURS AGO. WATER VAPOR ANIMATION
REVEALS THAT A WELL-ESTABLISHED TROPICAL UPPER TROPOSPHERIC TROUGH
(TUTT) EXTENDING ALONG THE 21ST LATITUDE CONTINUES TO SUPPRESS
POLEWARD OUTFLOW, BUT THE INHIBITION HAS EASED DURING THE PAST 12
HOURS AS THE STORM BEGINS TO SHAPE ITS OWN ENVIRONMENT. WATER VAPOR
ANIMATION ALSO EXPOSES A DEEP TROUGH IMPINGING ON OUTFLOW OVER THE
WESTERN SEMICIRCLE OF THE STORM. THUS THE ONLY QUADRANT WITH GOOD
OUTFLOW IS THE SOUTHEASTERN QUADRANT, AND OVER THAT QUADRANT,
CONVECTION SPREADING WELL AWAY FROM THE CORE TO THE SOUTHEAST IS
DISPERSING ENERGY FROM THE CORE. THE LATEST TWO MICROWAVE IMAGE
SERIES, A 130245Z AMSRE AND A 130613Z SSMI, BOTH CONFIRM A LACK OF
DEEP CONVECTION OVER THE NORTHERN SEMICIRCLE BUT THEY DO SHOW A WELL-
DEVELOPED MICROWAVE EYE. IN THE AGGREGATE, TS 08W IS SHOWING STEADY
INTENSIFICATION, ALBEIT AT A LESS-THAN-CLIMATOLOGICAL RATE. THE
STEERING MECHANISM IS THE SOUTHERN PERIPHERY OF THE SUBTROPICAL
RIDGE, WHICH IS ANCHORED BY A STRONG ANTICYCLONE OFF-SHORE OF HONSHU
(THE SAME FORCE BEHIND THE BRUTAL HEAT WAVE IN MAINLAND JAPAN). THE
ANTICYCLONE IS EXPECTED TO REMAIN STEADY AND STATIONARY THROUGH THE
NEXT 72 HOURS, WHICH WILL DRIVE TS 08W ON A STEADY COURSE TO THE
WEST-NORTHWEST WHILE IT INTENSIFIES AT A RATE OF APPROXIMATELY 15-20
KNOTS PER DAY. AFTER TAU 72, THE ANTICYCLONE IS EXPECTED TO WEAKEN
AND THEN DRIFT SOUTHEAST, OPENING A WEAKNESS OVER THE NORTHERN
RYUKUS. THERE IS PRONOUNCED DISPARITY IN MODEL GUIDANCE AFTER TAU
72, WITH NOGAPS AND GFS CURVING THE SYSTEM EAST OF THE KANTO AND
DIRECTLY INTO THE SUBTROPICAL RIDGE. EGRR IS THE EQUATORWARD
OUTLIER, KEEPING THE STORM AS A STRAIGHT-RUNNER. JGSM AND ECMWF
TRACK THE SYSTEM ALONG THE BOTTOM SIDE OF THE TILTING RIDGE, WHICH
IS THE SOLUTION THAT SEEMS THE MOST COHERENT AT THIS POINT. THE JTWC
FORECAST FOLLOWS CONSENSUS THROUGH TAU 72, THEN STAYS SOUTH OF
CONSENSUS, BETWEEN CONSENSUS AND ECMWF, IN THE EXTENDED RANGES. OF
GREATER CERTAINTY IN THE LONG RANGE FORECAST THAN THE TRACK IS THE
INTENSITY. IT IS PRUDENT TO NOTE THAT A POLEWARD TRACK WOULD NOT BE
THE COMMON RECURVATURE SCENARIO, WITH THE STORM ACCELERATING TO THE
NORTHEAST AND WEAKENING AS IT ENCOUNTERS SHEAR AND BOUNDARY LEVEL
MODIFICATION AS IT TRACKS INTO THE BAROCLINIC ZONE. THE CURRENT
SYNOPTIC PATTERN, WITH THE POLAR FRONT JET EXTENDING OVER NORTH
KOREA AND HOKKAIDO, WILL ALLOW THE STORM TO REMAIN IN TROPICAL AIR
AND A LOW SHEAR ENVIRONMENT, VIRTUALLY UNMODIFIED RIGHT UP TO
LANDFALL. SEA SURFACE TEMPERATURE ANALYSIS SHOWS THAT WARM WATER
EXISTS ALL THE WAY TO THE TSUSHIMA STRAIT, SO THERE IS NO REASON TO
EXPECT THE STORM TO WEAKEN UNTIL IT MAKES LANDFALL. THE LONG RANGE
INTENSITY FORECAST STAYS ON THE HIGH SIDE OF STIPS GUIDANCE, CLOSER
TO ECMWF, JGSM, AND GFDN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 130600Z
IS 15 FEET. NEXT WARNINGS AT 131500Z, 132100Z, 140300Z AND 140900Z.//
Rarely does JMA have an intensity equal to JTWC due to their different wind averaging methods. In this case, 55 kt 10-min appears more reasonable than 55 kt 1-min.

Re: WPAC: MA-ON - Severe Tropical Storm
IMHO, a good chance for RI once the TUTT dissipates allowing for outflow channels to kick in.
Looking at the size of this, may not be too long.

Do we really have to spell this out every time there's a Wpac storm?!? TOKYO is the official RSMC out here so please change the title back to Severe Tropical Storm. EDIT: Or at least add that JMA have it as STS.
Latest JTWC forecast looks pretty conservative on intensity forecast. JMA going for 100kts in 72hrs, never seen them make such a bold forecast.

Re: WPAC: MA-ON - Severe Tropical Storm
The following post is NOT an official forecast and should not be used as such. It is just the opinion of the poster and may or may not be backed by sound meteorological data. It is NOT endorsed by any professional institution including storm2k.org. For Official Information please refer to the NHC and NWS products.
Truly underestimated Ma-On continues to strengthen. I would place the intensity at 90 knots 1 minute winds based on it's overall organization and well formed eye which it had for nearly 24 hours.

Thanks for changing thread title!
I agree this certainly looks like a typhoon to me. JTWC prognostic reasoning makes for a very interesting read too. Similar to early one in terms of how good they're expecting environment to be off Japan as well as a major compliment to ECMWF. It's worth reading the whole thing. Despite that I think it will peak much higher than 110kts given what the global models have been hinting at and how aggressive JMA are being!

Re: WPAC: MA-ON - Severe Tropical Storm
Ma-on is a category 1 as of 1200z and the forecast calls for at least a category 3.
