A significant severe weather outbreak is underway today across much of the Northeastern U.S., including metro New York City and Philadelphia. NOAA's Storm Prediction Center has placed the region in their "Moderate Risk" area for severe weather. A fall-like low pressure system with a very powerful cold front will sweep through the region today, triggering widespread severe thunderstorms that may organize into a "derecho" event with damaging winds covering a large swath of the Northeast. A few tornadoes may accompany the event, and several tornado warnings have already been issued in New York, with a possible tornado touchdown in the Point Breeze section of the Rockaway peninsula in Queens. The same storm system killed four people on Friday in northeast Oklahoma; three of the deaths occurred when strong thunderstorms winds blew a mobile home into a ravine. Record heat was observed in advance of the storm's cold front yesterday; Wichita Falls, TX hit a record high of 109, the hottest temperature ever recorded there so late in the season. When the cold front blew through at 7 pm CDT, the temperature dropped 15 degrees in 16 minutes, falling to 66 degrees by midnight. Wunderground meteorologist Shaun Tanner has more on the severe weather potential for the Northeast in his blog.

90L in the Gulf not a threat to develop
A partial remnant of Hurricane Isaac off the coast of the Florida Panhandle, Invest 90L, continues to be disrupted by wind shear, and no longer has time to develop before landfall occurs along the Florida Gulf Coast tonight or Sunday. Visible satellite loops show that 90L has a small area of poorly organized heavy thunderstorms, which will bring some areas of heavy rain to Florida today and Sunday.

Leslie still struggling with cool waters
Tropical Storm Leslie continues to feel the impact of the the cool waters it stirred up due to its long pause south of Bermuda, and remains a 65 mph tropical storm. The storm has no eyewall, as seen on satellite loops, but has cleared out a large cloud-free center. As Leslie continues to move north over warmer water, the storm should be able to build an eyewall and become at least a Category 1 hurricane. However, Leslie is expected to pass far enough to the east of Bermuda today and tonight that top winds of 45 mph will be observed on the island. Bermuda radar shows a large area of heavy rain from Leslie is very close to the island.

Forecast for Leslie
The strong trough of low pressure pulling Leslie to the north will bring Leslie very close to Newfoundland, Canada by Tuesday night or Wednesday morning. At that time, Leslie should be weakening due to cooler waters and increased wind shear, and is likely to be a tropical storm. Heavy rain will be the main threat to Newfoundland. The latest 11 am EDT NHC wind probability forecast calls for a 24% chance that Leslie will be a Category 1 or stronger hurricane Wednesday morning at 8 am EDT, when the storm will be near Newfoundland. Even if the core of Leslie misses Newfoundland, the island will still likely experience tropical storm-force winds, since 39+ mph winds will probably extend outward from its center 180 miles to its west on Tuesday and Wednesday. Large swells from Leslie continue to pounding the entire Eastern Seaboard, and are creating beach erosion and dangerous rip currents.


Figure 3. Hurricane Michael as seen by NASA's Aqua satellite at 11:50 am EDT Friday September 7, 2012. At the time, Michael was a Category 2 hurricane with 105 mph winds. Image credit: NASA.

Hurricane Michael weakens to Category 2
Hurricane Michael remains a Category 2 storm with 105 mph winds, out over the open mid-Atlantic Ocean. Satellite loops show that Michael is still an impressive storm with a well-developed eye. None of the models show that Michael will threaten any land areas during the coming five days, and Michael will likely die at sea over cold waters northeast of Newfoundland in 5 - 7 days.

91L off the coast of Africa
A tropical wave that emerged off the coast of Africa on Friday has been designated Invest 91L by NHC today. Most of the reliable computer models are predicting that 91L will develop into a tropical depression by Wednesday. None of the reliable computer models foresee that this storm will be a threat to the Lesser Antilles Islands, but it is still early to be assuming that 91L will recurve harmlessly out to sea.

* AT 105 PM EDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED A
LINE OF SEVERE THUNDERSTORMS. THESE SEVERE STORMS EXTENDED FROM
CASHTOWN TO SABILLASVILLE...MOVING EAST NORTHEAST 45 MPH. THESE
STORMS ARE CAPABLE OF PRODUCING DAMAGING WINDS IN EXCESS OF 60
MPH.


Is that forward speed for real? Do we add on the actual wind speed to that, like with a hurricane? If so, 60+ mph seems low. Or, maybe it's the straight line wind speed, rather than it's travelling speed?


It's the forward speed the cell is traveling. This generally has nothing to do with wind speeds that you can expect from a cell.

Tropical cyclone information statement for:
Labrador
Newfoundland
Nova Scotia
Prince Edward Island.

For tropical storm Leslie.

The next statement will be issued by 3:00 PM ADT.

Leslie is moving very slowly northward. Still much uncertainty
When and where weather impacts will reach Eastern Canada.

------------------------------------------------- --------------------
==discussion==
The Canadian Hurricane Centre continues to monitor the evolution of
Leslie. The storm continues to move very slowly over the colder
water which it has stirred up. The winds are estimated at just below
hurricane force based on hurricane hunter aircraft data from last
night. Leslie should still regain hurricane strength on Sunday as it
intensifies while moving over warmer waters. Most of the computer
models still show a slow northward movement with acceleration early
next week. However - as mentioned and now observed - the computer
models are known to have difficulty simulating these ocean feedback
effects and situations where the atmospheric steering currents are
very weak. Given the latest developments Leslie will likely
strengthen to category 1 - but the storm is quite large with an
extensive area of rainfall, cloud cover and large waves.

In general, the threat of Leslie on Nova Scotia has been decreasing
but still enough to bear watching. The probability of some impact in
Newfoundland is greater, moderate at 40% for the Wednesday to
Thursday time-frame next week. This may seem contradictory to the
official track forecast which depicts the storm center over the
Avalon Peninsula early Thursday. However this position only
represents an average of an unusually broad range. Stay tuned to our
updates for the trend in the track and discussions.

One of The Key weather features that will tell the tale is the
behaviour of a trough of low pressure now approaching from the Great
Lakes. This feature is forecast to slowly intensify and move
southeastward over the weekend. During the early part of next week
the computer models are predicting that the trough will "pick up" the
hurricane and accelerate northward. There could be a front merging
with the storm and drawing moisture northward along it. However, all
this is contingent on the timing of the trough and position of the
tropical storm/hurricane.

Much smaller but more intense hurricane Michael over 2000 kilometres
east of Leslie now, will also move very slowly and is currently not
expected to affect Eastern Canada. Leslie and Michael will draw
closer to each other over the next several days. Since Leslie is
much larger, its possible impact on Michael would likely be to
shear-apart its upper clouds and acellerate it northward away from
Leslie. A true merging of the hurricanes is not expected based on
their differing sizes. But experience with this sort of situation is
limited and we will certainly monitor it.

Moderate surf conditions related to Leslie will persist along
south-facing coastlines of Nova Scotia and Newfoundland throughout
the next several days. If near the water, exercise caution knowing
that wave heights can vary significantly over a span of several
minutes and that rip currents can develop at local beaches.
Incident wave heights near 2 metres (7 feet) may break at the shore
at heights near 3 metres (10 feet).

The Canadian Hurricane Centre will continue issuing these general
information statements today and Sunday with more detailed track
forecasts possibly beginning early Monday.

little bit of Trivia from NOAA:



For the first time, National Weather Service forecasters were able to forecast a storm of this magnitude five days in advance and provide storm and blizzard warnings two days in advance. This was unprecedented. The five-day lead time allowed the entire NWS to begin preparations well in advance of the storm and warn the 100,000,000 people in the eastern third of the United States of this impending natural disaster. Prior to the “Storm of the Century,” the technology was not available to warn not only of a storm this far in advance, but also of its expected impacts.





This is a PDF of a local news letter here and on page 8 there is an article about it. I have read a lot about it since moving here.

I'm doubting this system will do too much in the way of heavy weather. The low level center seems to be coming ashore in the western panhandle, and although there is a lot of moisture out there, I don't think the dynamics are in place for any organized severe weather


Looking at the satellite, I noticed this. If the ingredients are/were finally coming together for 90L to get a bit more organized, it appears this opportunity will end as it moves ashore. We will still get some rain moving in from the Gulf over the next couple days.

STORMS ARE CAPABLE OF PRODUCING DAMAGING WINDS IN EXCESS OF 60
MPH.


Is that forward speed for real? Do we add on the actual wind speed to that, like with a hurricane? If so, 60+ mph seems low. Or, maybe it's the straight line wind speed, rather than it's travelling speed?
