Mixed feelings/thoughts on this. Poster certainly has a point. Those are also lower income/wealth areas, not just predominantly black. Many other areas also equally underserved that have different demographics. Radars are expensive, so makes sense to put them places where you have more people/higher density to get more for the funds. Where those radars were placed was decided over three decades ago. There have been efforts/research in the past to have small "gap filling" radars, but that's infrastructure spending and we know how that's gone in America the past half century.

I'm in that line of "without excellent coverage" through SC and it actually owns because CAE, CHS, ILM, GSP, RAX and CLT TDWR all overlap coverage there and I can keep switching sources and getting a new scan every minute or two.

it's too bad that America is a poor backwards third world nation and can't afford weather radar.

Canada is even worse for radar coverage and we were just talking about how in America you at least have overlapping coverage in a lot of areas, lol...

Do they even use radar for weather forecasting? What exactly do you lose in a forecast if you don't have radar close by?

Don't satellites provide way more detail about storms? Like the NWS still issues specific and accurate tornado warnings outside of radar zones right?

I think you have to have the radar to tell if a storm cell is turning into a tornado. While satellites can show cloud cover I don't think it can discern rotation.

yeah that tornado in KS was radar indicated, so if there's no radar coverage for an area you get less warning for tornados. and in this part of the country that is bad. but then again most tornados hit unpopulated areas

I'm no expert but I think radar gives you higher resolution and can do cloud penetration so you can get cloud or rain density, real time updates for local areas, etc. We have a radar in my city and you can see what neighborhoods are getting rain and I can pretty accurately guess if I can walk to the store without getting rained on if it's on/off throughout the day.

Regardless, while the Pee Dee is definitely a very swampy stretch of water I'm very curious why it's so clearly distinct on that map, like the guy upthread said it's surrounded by several airports and there's an air force base not too far away either

i'm not an expert, but doppler radar gives you information about vorticity that satellites don't get since doppler radar can measure orthonormal water vapor velocity (wind). radar also updates more often than satellite imagery and has much better resolution for actual rain instead of just integrated water vapor column density. you want radar for near term severe weather warning systems and you want satellites for long range weather forecasting and modelling.

It's this. You can't get the kind of high resolution cross-section imagery of a specific storm from satellites that makes it possible to send out tornado warnings like with the national NEXRAD system.

Satellites are passive and observe radiation emitted by clouds. They only see the top, can't see within clouds. Radars are active, transmitting pulses of energy that penetrate clouds. That energy gives information that allows you to infer the size/amount of precipitation and measure radial velocity. Radars also scan progressively higher into the clouds/storms, giving a sense of 3D structure. Radar and satellite compliment each other and are both critical.

Radar especially helps for the very short-term forecast, like the next 3 hours. Weather forecasters also typically monitor current weather to send out alerts, so radar helps with that too. E: radar reflectivity is also starting to be included in weather models to help determine the initial conditions.

Cooper Congaree, Ashley Saluda, Edisto Black, Petey Waccamaw all sound like total badasses. But then there's Wateree Broad.

Any thoughts itt on the GFS model upgrades? Or is this just a wait-and-see situation? It's pretty amazing what the models can forecast these days.

I don't care so much about one model upgrade. Ensemble data is what should be looked at. (And eventually the plan is for all NCEP models to meld into one unified ensemble system both for short and long range forecasting.)
