Late in the day yesterday Tucson finally got a bit of sun before dark - above image is from 6 pm. This morning, Easter Sunday - 31 March, is dawning clear and sunny, as image looking north from Kitt Peak (below) shows at around 6:30 am.
Obviously, March is coming to a close after producing almost nothing in the way of precipitation for the Tucson area. Only rainfall here at the house was 0.03" on the 9th. Compared to last March, this past month has been dry and also warmer - wrt morning lows. During March 2012 there were 19 mornings here at the house with lows below 40F, 8 mornings with freezing or below, and 5 mornings with lows in the 20sF. This month there were only 9 mornings with lows below 40F and 1 day (the 1st of March) with a low below freezing (29F). Quite some difference between the two years! April 2012 brought 6 days in the 30s, as well as the year's first 100+ high - we'll see what this year has in store for us.
There continues to be little on the weather horizon. It has been interesting watching the ECMWF the past 5 days or so. That model has continued to forecast an interesting weather pattern, with a 500 mb closed low over the Southwest. However, the interesting pattern has continued to be forecast out at day 9 or 10 - thus, the next weather-maker has not gotten any closer. The 500 mb ECMWF forecast below is valid at 00 UTC on April 10th. This seems, at least to me, to be somewhat unusual behavior for the European model.
