Third attempt to launch JPSS-1 weather satellite scrubbed due to weather

The Joint Polar Satellite System, first of 4, is set to launch November 14 at 1:47 a.m. PT  from Vandenberg Air Force Base. 

Update Thursday - 

The launch of the newest polar satellite was scrubbed again Thursday due to strong upper level winds. A new window is scheduled for Saturday at 1:47 a.m. Pacific Time (4:47 a.m. ET). Winds are expected to relax by then.

Update Wednesday morning - 

The JPSS-1 satellite launched was scrubbed Wednesday morning and has been rescheduled for 8 p.m. PST Thursday (11 p.m. EST), NASA said. Click here to watch it live.

Update Tuesday morning - 
The JPSS-1 satellite launched was rescheduled for Wednesday at 4:47 a.m., according to NASA.
The launch was scrubbed due to a last-minute technical problem,
JPSS-1 satellite 
Soon, the poles will be orbited by the latest and best technology available. The first Joint Polar Satellite System, is set to launch at 1:47 a.m. Pacific Time from Vanderberg Air Force Base California. The satellite, aboard a Launch Alliance Delta II Rocket, is the first in a series of high-tech satellites that will improve three- to seven-day forecasts.
The JPSS-1 is the next generation of polar satellites, loaded with the most advanced instruments, which will collect information from Earth’s atmosphere, land and ocean’s surfaces. Its three sister satellites -- the JPSS-2, 3 and 4 -- are set to launch in 2021, 2026 and 2031 respectively.
Polar satellites are crucial in weather forecasting. JPSS-1 will help forecasters create more precise forecasts up to seven days in advance. Vegetation will also be closely observed, and the satellite will monitor how weather is affecting the forests, and the crops that provide our food. The ocean’s temperatures will also be measured closely and with greater detail. The satellite will keep tabs on the atmosphere to allow for earlier warnings of severe weather. It will also be able to watch forest fires and volcanoes, monitor air quality and enhance public safety.
Unlike GOES-16, launched November 2016 from Cape Canaveral, the Joint Polar Satellite System, JPSS-1, will orbit the Earth from the North Pole to the South Pole, 14 times per day and will scan the entire Earth twice every day. This satellite really moves!
It will be known as NOAA-20 when it reaches orbit at 512 miles above the Earth, and it will replace the Soumi-NPP, which was a prototype test bed, becoming the primary U.S. polar-orbiting satellite.
WHY IS JPSS SO IMPORTANT?
You know how you often hear the weather person comparing “models" when a storm approaches? Well, when numerical data is not frequently fed into the models, the margin of error becomes larger. The famous European model is fed with more and better data.
The JPSS will provide more data, and this data will be fed into the prediction models. We are all looking forward to a better Global Forecast System (GFS) -- the American model.
