Woke to light showers this morning (Tuesday March 23 2010) as models were slow developing precipitation across southern Arizona. Ground is damp here but only a trace in gauge. Last evening's model runs indicated no rain, or only a Trace to a 1/10", with this 500 mb feature in the southern train of flow, so it remains to be seen if any signifcant showers develop in southeast Arizona. Regional radar shows some stronger echoes in southwest portion of state. Range from radars indicates beams are in the ice/mixed phase portion of the cloud, so the high reflectivities may be somewhat deceptive. However, I note that Phoenix Skyharbor is having moderate rain at this time. So, an interesting day on tap with a warm, low latitude system that has had the models struggling.
