More severe action likely

Saturday has the potential to be bigger than today. The computer models suggest instability is stronger, and the decent shear (but not awesome) should hang around. Also, temperatures high up, at 300mb are cooling and this should lead to higher storm tops and therefore a chance of larger (golfball size) hail. Today, low to mid level cloud nearly ruined the day, but luckily it cleared after lunch time. Further low-mid level cloud is likely tomorrow but I don’t think it will be thick enough to stop the storm activity. Also, surface temperatures are expected to climb towards 30C (up from 25C today) and this should help fuel bigger storms. 850mb temps should increase a little but hopefully the warmer temps at the surface will reduce the threat of a flop.
Severe thunderstorms are again a threat on Sunday but at this stage, Saturday looks like the bigger day. Stay tuned.
