When does a convective discussion become a ‘tornado warning’? Answer - when an ill-informed journalist on a local rag completely misinterprets the information. Tornado warning issued for Dorset WWW.BOURNEMOUTHECHO.CO.UK A TORNADO warning has been issued for Dorset today.

The trough and associated squall modelled to move across the SW and into the SE and EA later tomorrow (Sat 28th Oct) needs watching. Potential for bow elements and embedded structure given the parameters. GFS high res returning up to 500 0-3km SRH across the south at 15Z.

Mesoscale trends look favorable for a couple of discrete supercells in far NE MO, initiating at around 22Z and tracking NE in an environment supporting top end SRH. The last two HRRR runs on simulated has a tornadic cell initiating around Edina, MO and moving towards Burlington, IL by 00Z. DPs already approaching 66F into central MO now. The current activity should be monitored for an OFB further enhancing the vectors. The nocturnal risk into AR later is also looking serious and might well end up as the headline maker.

Hi - I can help you with this and indeed it is frustrating. The data in the Wiltshire/W Hampshire area is augmented by the radar site near West Dean, a few miles SW of Salisbury. This station has had a problem for quite a while where a quadrant of the scan in a wedge pointing east is corrupted, resulting in 'lines' and wedges of false enhancements and diminished returns. It doesn't happen all the time but it can be annoying when tracking fine detail and intensities.
