HTC News - May 17, 2020

As the saying goes "April showers bring May flowers": Here in beautiful, downtown Denison, Texas we had some interesting weather the last few days. Tom Miller is usually on-spot with our weather forecast.....but not this time!! Ever wonder how the weather is predicted?
6 tools our meteorologists use to forecast the weather
1. Doppler Radar
Doppler Radar is the meteorologist’s window into observing severe storms. With 159 radar towers across the United States, NOAA’s National Weather Service has comprehensive coverage of the continental U.S. and partial coverage of Alaska, Hawaii, Puerto Rico and Guam. Doppler radar detects all types of precipitation, the rotation of thunderstorm clouds, airborne tornado debris, and wind strength and direction.
2. Satellite Data
Weather Satellites monitor Earth from space, collecting observational data our scientists analyze. NOAA operates three types of weather satellites. Polar orbiting satellites orbit the Earth close to the surface, taking six or seven detailed images a day. Geostationary satellites stay over the same location on Earth high above the surface taking images of the entire Earth as frequently as every 30 seconds. Deep space satellites face the sun to monitor powerful solar storms and space weather. NOAA also uses data from satellites operated by other agencies and countries.
3. Radiosondes
Radiosondes are our primary source of upper-air data. At least twice per day, radiosondes are tied to weather balloons and are launched in 92 locations across the United States. In its two hour trip, the radiosonde floats to the upper stratosphere where it collects and sends back data every second about air pressure, temperature, relative humidity, wind speed and wind direction. During severe weather, we usually launch weather balloons more frequently to collect additional data about the storm environment.
4. Automated Surface Observing Systems
ASOS (automated surface observing systems) constantly monitor weather conditions on the Earth’s surface. More than 900 stations across the U.S. report data about sky conditions, surface visibility, precipitation, temperature and wind up to 12 times an hour. Nearly 10,000 volunteer NWS Cooperative Observers collect and provide us additional temperature, snowfall and rainfall data. The observational data our ASOS and volunteers collect are essential for improving forecasts and warnings.
5. Super Computers
NOAA’s Weather and Climate Operational Supercomputer System (WCOSS) is the backbone of modern forecasting. With 5.78 petaflop computing capacity it can process quadrillions of calculations per second. Our supercomputers are almost 6 million times more powerful than your average desktop computer. Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.
6. AWIPS
AWIPS (NOAA’s Advanced Weather Information Processing System) is a computer processing system that combines data from all the previous tools into a graphical interface that our forecasters use to analyze data and prepare and issue forecasts, watches, warnings. This system uses NOAA supercomputers to process data from doppler radar, radiosondes, weather satellites, ASOS, and other sources using models and forecast guidance products. After meteorologists prepare the forecasts, AWIPS generates weather graphics and hazardous weather watches and warnings. All this helps our meteorologists create more accurate forecasts and faster than ever before.

Birthday/Anniversary/Celebrations:
Monday: HiTcchRedneck - John from Pennsylvania
Thursday: howln - Jim from Maryland
If it's your birthday/anniversary/special occasion let us know and we will celebrate with you.

Just called to check in and say "Hi": On Wednesday I received a call from John Powell - wolf_with_the_red_rose - our member from North Carolina. John wanted me to say hi to everyone for him. He's doing well but does not have computer access. I know several of you have asked about him recently. What members have you heard from?

Try your luck at being "Truck of the Month"!! Post a picture and a write up of your ride between the 1st-21st then we vote the 22nd-months end. After the voting the winner will be messaged for email info. The email is for the digital TOTM award. Printing and shipping them was getting pricey and time consuming. The awards will be printable on your end and then you can frame them. Thanks to Keith (charged392) for heading this up!

It's with great sadness that have officially cancelled this year's rally that was scheduled in Fort Worth, Texas. Just a reminder that if you have already reserved your hotel room be sure to call and cancel your reservations!

Chatroom is back!! Join us every Thursday evening at 7:00 CST for chatroom. See what going on with the rest of the HTC'ers.

PRAYER REQUEST:
If you have a prayer request you would like to share either add it to this thread or PM me.

*HemiSuperbee - Mark - health concerns

*Rancher - Doug said to take him off the list but I think a quick prayer for his general health issues isn't a bad idea

*Doc's mother - recent fall resulting in fractured femur & surgery, she is currently in rehab

*Studmuffin - Morris' brother-in-law, David, with liver failure

*boedacres - Steve - health issues including diabetes

*SuperBee - John & his wife - health issues

*Those affected and impacted by the Covid 19 virus both physically and financially!

Have a great week!!!
