Re: EPAC: ODILE - Tropical Storm
Isn't shear supposed to decrease by now？Still no signs of that happening

I noticed that shear is always a challenge when it comes to forecasting it.

It's very fickle in all basins.

Odile's intensity forecast is definitely trick. Although shear was not expected to be an issue initially, I can't say it's a surprise--I saw that upper-level low over the Gulf working westward towards the storm the other day, but Odile was forecast to have a well-developed anticyclone by this point.
That said, the upper-level low is forecast to weaken as it moves over Mexico, leaving the question of how strong Odile can become between tomorrow and Sunday. Sea surface temperatures are very warm and mid-level moisture is abundant, so assuming upper-level winds do indeed slacken, rapid intensification remains a distinct possibility.
This probably isn't going to become the Category 4 I first thought it would, however.

TROPICAL STORM ODILE DISCUSSION NUMBER 8
NWS NATIONAL HURRICANE CENTER MIAMI FL EP152014
800 PM PDT THU SEP 11 2014
Strong northeasterly shear continues to push nearly all of Odile's
deep convection to the southwest of its center. The cyclone
actually appears a little less organized than it did earlier today,
and Dvorak final-T numbers have decreased from both TAFB and SAB.
For now, however, the initial intensity is held at 50 kt based on
an average of the CI numbers. The northeasterly shear over Odile
is being caused by the flow on the west side of an upper-level low
located over eastern Mexico. This feature is forecast to move
westward, which should cause the shear over Odile to finally
decrease in about 24 hours. Gradual strengthening is still forecast
during that time, but lower shear should support a faster rate of
intensification after 24 hours. The current shear has decreased
the amount of time that Odile has for significant strengthening,
and the intensity models have responded by showing much lower peak
intensities in a few days. The updated NHC forecast has been
adjusted downward for the entire forecast period and is near the
SHIPS model solution, which is the highest of the reliable guidance.
Odile has been meandering during the past few hours, and the
estimated 12-hour average motion is 295/2 kt. The sheared nature
of the cyclone could cause the center to continue meandering, but
overall Odile should drift westward or northwestward during the
next 24 hours. After that time, a strengthening mid-level ridge
over Mexico is expected to cause the storm to accelerate
northwestward through day 5. The track models have changed little
on this scenario, and the new NHC track forecast is mainly an update
of the previous one.

TROPICAL STORM ODILE DISCUSSION NUMBER 9
NWS NATIONAL HURRICANE CENTER MIAMI FL EP152014
200 AM PDT FRI SEP 12 2014
Deep convection has recently redeveloped closer to the center of
Odile, as the shear is perhaps beginning to weaken a bit over the
cyclone. Data from two ASCAT passes and a blend of the latest Dvorak
estimates from TAFB and SAB support maintaining the initial
intensity at 50 kt. The SHIPS model shows the vertical shear
gradually decreasing over the cyclone during the next day or so,
which should allow for gradual intensification in the next 12 hours
and steadier strengthening after that time. The intensity guidance
continues to trend lower this cycle, and the NHC forecast has again
been adjusted downward, but still shows Odile becoming a hurricane
in about 24 hours and reaching a peak intensity of 85 kt in 72
hours. Late in the period, the cyclone will begin moving over cooler
waters, which should result in steady weakening. The NHC forecast is
above the latest IVCN consensus and is close to the SHIPS model at
36 hours and beyond.
Odile has moved little since the previous advisory, as the cyclone
remains in a region of weak steering currents. The best estimate of
the initial motion is a westward drift at 2 kt. A slow westward to
west-northwestward drift is expected during the next 12 to 24 hours,
followed by a gradual acceleration toward the northwest as a
mid-level ridge amplifies to the northeast of the cyclone. Overall,
the track guidance remains in general agreement on this scenario,
but much of the guidance has shifted to the right at days 4 and 5.
The new NHC forecast has been adjusted in that direction and is
close to the EMCWF at the end of the period, but now lies to the
left of the TVCE multi-model consensus.
The initial 34-kt wind radii have been adjusted based on data from
the aforementioned ASCAT passes, which show a large wind field in
the southern semicircle.

Take a look at this this morning, its looking like an intensifying system

Re: EPAC: ODILE - Tropical Storm
TROPICAL STORM ODILE DISCUSSION NUMBER 10
NWS NATIONAL HURRICANE CENTER MIAMI FL EP152014
800 AM PDT FRI SEP 12 2014
A recent SSMIS microwave overpass and Dvorak infrared BD-curve
enhancement imagery show that deep convection, with associated -80C
degree cloud tops, continues to form over the surface center,
indicative of the subsiding northeasterly shear. A blend of the
subjective intensity estimates yields an increased initial intensity
of 55 kt. It's worth noting that the SHIPS model indicates an
initial vertical shear of 17 kt, while the UW-CIMSS shear analysis
only shows only about 5-10 kt of shear. Additionally, GOES-13
satellite-derived 100-350 mb winds indicate a more diffluent
pattern over the cyclone. The NHC intensity forecast is basically an
update with only a slight increase adjustment through 48 hours to
reflect the increasingly more favorable upper-level wind
environment.
Odile continues to drift westward this morning within weak mid-level
steering flow. Large-scale models continue to be in excellent
agreement with a mid-level ridge building over northern Mexico and
the Baja California peninsula beyond the 24 hour period. Odile is
expected to gradually accelerate northwestward through the remaining
portion of the forecast in response to this change in the synoptic
steering pattern. The NHC official forecast is very close to the
previous advisory and is based on a blend of the TVCE multi-model
consensus with emphasis on the ECMWF global model.
FORECAST POSITIONS AND MAX WINDS
INIT 12/1500Z 15.5N 105.0W 55 KT 65 MPH
12H 13/0000Z 15.6N 105.5W 65 KT 75 MPH
