Storm Forecasters Adding Extra Layers To Warnings

Associated Press    8/12/2014

NORMAN, OKLA - The National Weather Service Storm Prediction Center said Monday it will add two threat levels to its weather outlooks so people aren't surprised by
really bad storms on days with just a "slight risk" of tornadoes, hail or
high winds.

  Beginning Oct. 22, forecasters can say whether slight risk days are
"enhanced" or "marginal" or just plain "slight."  Other categories remain,
including "high" and "moderate."

  The Norman, Oklahoma based center traditionally targeted local
forecasters and broadcasters across the U.S. with their advisories, known as
"convective outlooks," but the Internet makes that data available to anyone
with a computer and basic scientific knowledge.

    "We serve a very diverse group," said Greg Carbin, the center's warning
coordination meteorologist. "We have a hybrid audience of highly
sophisticated decision-makers," ranging from "expert users of weather
information" to "the head of the household in those parts of the country
that are often targeted by severe weather."

  The Storm Prediction Center for years classified the risk as high,
moderate or slight, "and you can have killer storms in a slight risk,"
Carbin said.

  The system now mimics scales for tornado damage, hurricane strength and
the former Homeland Security terrorist threat sale.
  "It gets us to five categories.  Now we have a scheme where we can rank
something 1-5,"  Carbin said.

  A public comment period drew 700 responses, mostly from individuals,
government officials and the media.

NWS and OkArkSkywarn Weather Alerts via Email - Q&A!!
In January, we rolled out an enhanced weather email alert system for our members.  This system allows you to register up to 3 email addresses, as well as up to 3 text devices, to receieve any or all of 20+ weather products produced by the National Weather Service Weather Forecast Office in Tulsa.

This system is FREE to all members and should be a very positive addition to the tools used by Emergency Managers and Skywarn volunteers in helping to protect our communities.  It is also just a great way to stay up to date with weather and be alerted of developing situations of interest to you.

There are three steps required to use the system.
1.  Have an account on the website.
2.  Register your email and text devices on the website.
3.  Select the products, counties, and alert levels that meet your needs.

That's it!!

There have been a few questions as expected, so we will be creating a FAQ for this service soon.  In the mean time, if you have any questions feel free to send them to us at:

We also welcome any feedback on this new system, good or bad, so let us know!

Gibson Ridge Radar Software
Several have asked about the Gibson Ridge Radar Software.  You can download it at

What is known as Level III WSR-88D data are available free and the GRLevel III software ($80) is hard-coded to retrieve the free data.

The Level II WSR-88D data are a more raw form of the information and not as widely available.  Iowa State University feeds data from all 88D sites for free.  I will edit this soon with the URL for this data feed.  The Level II software ($250) can make 3D radar images.

These same Level II data, plus a lot of other really good data sets (including APRS positions) are available from Allison House for a small fee...about $20 /

The Gibson Ridge software allows you to load GIS shape files to display any map background you can find or make.

You can also plot other data in the software...WFO Tulsa has some experimental feeds that plot storm reports and our outlooks (warnings are plotted automatically in the software).

You can find free surface data plots...including Mesonet...and SPC watches at:

We will have this software on the net controller desk soon.
