I'm Jay Farlow. W9LW is my amateur (ham) radio call sign. I've been a ham since 1973. I've been a volunteer storm spotter for the National Weather Service SKYWARN program since the 1970s. I've also been a volunteer EMT and firefighter and member of a disaster medical assistance team. I advise the leadership team of Associated Churches Active in Disaster, a ministry of Associate Churches of Fort Wayne and Allen County. Learn more about w9lw at www.qrz.com/db/w9lw.
The National Weather Service (NWS) is developing a web application that displays radar data and other information on a map. The Enhanced Data Display (EDD) can be a useful tool for SKYWARN storm spotters, especially those who do not have a radar program like Gibson Ridge’s GRLevel3.
EDD can display standard radar base reflectivity data (that common radar image that shows where the rain is and how heavy it is). It can also show velocity products, that show potential rotation in storms.
EDD can also geographically display a large number of NWS products, including convective outlooks, mesoscale discussions, watches and warnings. Once you display any of these products, you can zoom in to specific areas of interest. This can be useful, for example, if you want to learn whether your home is under a level 1 (marginal) or level 2 (slight) risk in a convective outlook, or whether your home is inside or outside a tornado warning polygon.
You can also optionally choose to add layers for features such as county lines, NWS county warning area lines, etc.
Although the application is officially still experimental (which means it might not always work as expected), it’s open to the public and available for you to try. I recommend playing around with it to see how it could help you with your situational awareness.
Six Fort Wayne amateur radio operators spent several hours May 23 assisting residents with their NOAA Weather Radio (NWR) receivers.
Tom Baker, N9TB; Jay Farlow, W9LW; Steve Haxby, N9MEL; Joseph Lawrence, K9RFZ; Steve Nardin, W9SAN; and Howard Pletcher, N9ADS worked alongside representatives of WANE TV, the Allen County Office of Homeland Security and the National Weather Service at the Walgreens store on Lower Huntington Road to configure NWR receivers.
Volunteers assured that the receivers’ specific area message encoding (SAME) and receive frequency settings were correct, so users would receive warnings that the NWS issues for their home counties.
WANE TV had promoted the three-hour event, which was duplicated at other locations in the TV station’s market area. The Office of Homeland Security estimates that 100 citizens were assisted.
As Joseph put it, the event “was an excellent example of cooperation between local weather personalities, NWS staff, DHS, and amateur radio operators to support our community. Good PR for amateur radio can go a long way in protecting ham radio bands from public utility spectrum grabs.”
Today is the fifth anniversary of a “derecho” thunderstorm that did widespread damage in northern Indiana and locations to the southeast.
“At the peak of the event,” writes the northern Indiana office of the National Weather Service, “the Fort Wayne International Airport observing equipment observed a peak wind gust of 91 mph.”
“Winds were as strong as an EF-1 tornado over a widespread area,” the NWS web page continues, “which resulted in immense damage along the storm’s entire path.” (Emphasis added by W9LW.)
One of the best lessons of that storm should be that we can have massive damage without a tornado. This was a particularly dangerous severe thunderstorm, but there’s no such thing as a “particularly dangerous situation” thunderstorm warning, so we need to pay attention to all severe thunderstorm warnings, even though such warnings are not uncommon.
The title of this post is one of the main points of a presentation I heard at the DuPage County (Ill.) Severe Weather Seminar March 11. College of DuPage meteorology professor Paul Sirvatka reminded spotters that the key to spotting a tornado in a classic supercell is knowing where the updraft is. As Dr. Sirvatka put it, a tornado is a “big sucky thing” that forms under an updraft.
Unfortunately, updrafts are not always easy to find. Depending on your location, important storm features can be obscured, making spotting difficult. And the closer you get to a storm, the more difficult it becomes to identify the important features.
A large part of Indiana has a level two (out of five) risk of severe weather today (April 20, 2017) and this evening, according to the National Weather Service (NWS) Storm Prediction Center. The primary threat today is damaging straight-line winds or gusts of 58 mph or greater, but an isolated tornado cannot be ruled out in much of northeastern and east-central Indiana.
That makes now an especially good time for Hoosiers (and everyone else who lives in an area that ever receives severe weather) to make sure they have good ways to know about any warnings their local NWS offices issue.
So, here’s my list of the best ways to get tornado, severe thunderstorm and flash flood warnings. Continue reading →
For 11 years, Alabama broadcast meteorologist James Spann (ABC 33/40, Birmingham) and several of his friends in the weather enterprise have produced a weekly podcast (internet talk show) called WeatherBrains. It was the first in what has become a group of weather-related podcasts that are jointly celebrating the first-annual National Weather Podcast Month in March.
The weather brains normally record WeatherBrains on Monday evenings. Audience members can watch the discussion live on YouTube, watch it later on YouTube or download the program as an audio recording for listening at their convenience.
W9LW’s Ramblings had chance to talk to Spann about the show that started the weather podcast genre and now has an audience in the tens of thousands. Watch the 14-minute interview on YouTube or read it below. The transcript includes a few helpful notes and hyperlinks.
The National Weather Service (NWS) plans to change its website, www.weather.gov on March 7. When the change takes place any bookmark you’ve created to a specific forecast will no longer work. You’ll have to go to the home page at the URL above, enter the location for which you want a forecast and create a new bookmark for the page that appears. For more information, see the message below that the NWS sent to all Weather-Ready Nation ambassadors.
Dear Weather-Ready Nation Ambassadors,
As part of our continued effort to modernize weather.gov, the National Weather Service (NWS) is upgrading our point forecast, zone forecast, and product pages. Once these changes go live on March 7, all existing bookmarks to forecast.weather.gov will change. Links to a forecast page will display an error message that includes a URL to the new location. You will need to update your bookmarks to continue to access our forecasts quickly after the upgrade. After March 7, the new URL can also be found by searching for your location from forecast.weather.gov or www.weather.gov. These changes will not impact office pages located at www.weather.gov
If you run an automated process to get NWS data from forecast.weather.gov, you will need to switch to the new developer API by March 7. Specifications for the new API can be found here.
The primary focus of the upgrade is to make the forecast pages more reliable during weather events, but there are some new benefits of new forecast pages that include:
Addition of 7-day hourly forecast information to the point forecast page
A new mobile-friendly landing and graphical/tabular forecast page
Low-bandwidth optimization for all pages, on a partial roll-out at launch
Option to automatically detect your location on a mobile device
A new widget mode that allows you to customize the information on the point forecast
We overhauled the architecture of our application platform to provide a more stable and consistent service to meet the demand of severe weather events. The platform also introduces a modernized API that will make it easier for web developers to create high-quality applications and services to share NWS data. The updated web site now provides a complete mobile-friendly experience with optimizations for low bandwidth and customized weather widgets. We also have new data centers located in College Park, MD, and Boulder, CO, to provide 100% backup capability for the operational data used within the forecast process.
We look forward to providing you with useful and timely information using our improved connectivity and new design.
The people of Albany, Georgia continue to need volunteer assistance to recover from last week’s tornado outbreak. One of my favorite relief organizations sent today the email message below, which explains why the need for volunteers from outside the area has increased. Please share this information with any congregations or others who might be interested in helping.
IMPORTANT: Please note that if you need lodging, please do not leave your home until you have received a CONFIRMED RESERVATION. Our field team cannot accept anyone who does not have a CONFIRMED RESERVATION.
DEAR OB VOLUNTEERS,
As we move into “Week 2,” we often refer to it as “Phase 2,” because the local volunteer response begins to drop dramatically as businesses reopen, schools reopen and residents return to work. These factors significantly lower our volunteer numbers, which means that we need out-of-town volunteers even more now. We are writing you today to ask you to consider bringing a team to help us help these precious residents over the next 2 – 3 weeks.
Operation Blessing is accepting volunteers daily at 8:00 AM (Monday – Saturday) at New Birth Fellowship Church in Albany, GA. We have two orientation times each day. Orientation begins at 8:30 AM and 1:00 PM. Operation Blessing will provide everything you need – work assignments, tools, and lunch. All we ask is that you provide your own transportation to and from the work sites. No reservations are needed for daily volunteers.

The amateur radio SKYWARN net based in Fort Wayne will undergo slight changes, effective Feb 1, 2017. Formerly known as the IMO SKYWARN Quadrant Two Net, it will now be referred to as the Allen County SKYWARN Net. The net will continue, however, to accept and relay reports from spotters outside Allen County, including stations in places like DeKalb and Defiance County, which were not officially part of the former quadrant net’s responsibility.
