The University of Oklahoma Student Chapter of the AMS (OUSCAMS) is presenting a Tornado Forecasting Workshop with Storm Prediction Center’s Rich Thompson. The series starts this Tuesday (Feb. 3), and runs from 7:30 – 9:00 p.m. CT. They will broadcast the workshops live on YouTube and record them for later viewing on the Chapter’s YouTube site. A flyer and current schedule of events is available below. Visit the OUSCAMS social media sites for more information. Other scheduled presentation include:
February 10 – Severe storm ingredients (low-level moisture and lapse rates)
February 17 – Severe storm ingredients (vertical shear and lift)
March 3 – Supercell and tornado conceptual models (plus composite parameters)
March 10 – Tornado patterns (synoptic and mesoscale)
March 24 – Convective mode forecasting (squall lines vs. discrete cells)
April 7 – Tornado parameter climatology (spatial and temporal distributions of CAPE and shear)
April 14 – Numerical models and statistical techniques (convective schemes and post processing)
April 21 – Real-time forecasting exercise
The potential for wintry weather across the Central Carolina SKYWARN coverage area exists for late Tuesday night through Wednesday morning January 13-14, 2015.
At the direction of the National Weather Service, Central Carolina SKYWARN will hold directed nets on the 146.88 repeater at the top of each hour beginning at 6am Wednesday morning for the duration of this winter weather event. The NWS will be looking for the following reports from spotters:
- Ice accretion (accumulation)
- Downed trees and power lines
- Road conditions
Thanks for your reports!
SKYWARN Recognition Day 2014 officially takes place Saturday, December 6 from 0000-2400 UTC. Over 100 National Weather Services offices across the nation, including the Raleigh National Weather Service, are expected to participate in this annual event.
SKYWARN Recognition Day was developed in 1999 by the National Weather Service and the American Radio Relay League to celebrate the contributions that SKYWARN radio operators/spotters make to the National Weather Service. During a 24 hour period, SKYWARN operators visit NWS offices and contact other radio operators across the world.
Central Carolina SKYWARN, operating under the call sign WX4NC, will join in the fun on Friday night (December 5) from 7-9 PM and Saturday from 9:00 AM to 5:00 PM, making contacts on the WB4TQD 146.88 repeater, the K4ITL 147.105 repeater, the K4ITL 147.135 repeater, the Carolina 440 UHF Link System, IRLP (node 9219), Echolink (WX3H and WX4NC), and HF (10, 15, 20, 40 & 80 meters SSB). Ask a SKYWARN operator on the 146.88 repeater for our frequencies.
Radio operators will exchange names, call signs, locations, signal reports, and a 1or 2-word weather report.
A QSL card will be available for this event. Stations logging a contact with WX4NC may send a SASE envelope to the following address to receive a QSL card:

Hope to get you in the log!
The 147.105 machine, our primary back up, is now operational as of 1:45 PM, September 11, 2014, after being off the air due to ice damage. Hats off to K4ITL for making this happen!
Per the direction of the Raleigh National Weather Service, Central Carolina SKYWARN will no longer take reports of “1 inch or more of rainfall in an hour’s time or less.” The NWS has determined that this amount of rainfall does not necessarily result in flooding and therefore should not remain a criterion to report. We will continue to take reports of “flooding and flash flooding where none normally occurs.” This change was effective September 4, 2014.
