Tucson Weather, 11/30/09 – Southern Route

2007 Snowman waits for rebirth
Winter Weather Advisory for Tucson vicinity above 4,500 feet has been canceled.
I’m looking at the IR satellite loop this morning and the cut-off low over northern Mexico seems to be drifting south still. At least to my eye. Could be one reason why the National Weather Service is highlighting heavier snow for the mountains south of Tucson as opposed to the Catalina’s. Like I mentioned last night, this storm seems to be taking the southern route. Not as good for heavy snow for Mt. Lemmon and the Catalina’s. The good news is, the low is going to take it’s time leaving the area, so we have a chance to see bands of showers, thunderstorms and mountain snow moving across Tucson and vicinity through tonight.
El Nino is being blaming for shutting off our Monsoon early this past Summer. Perhaps now the Winter El Nino pattern is kicking in that would bring us more rain and mountain snow. That would make me very happy :-)
Tucson Forecast:
Mostly cloudy today with scattered showers. High near 58. Tonight becoming partly cloudy and a low near 36. Mostly sunny on Tuesday with a high near 62.
