Back In Tucson

We have been on a road trip since last Friday morning and have just returned. We were in Winslow this morning, where the low temperature was a pleasant 58F. However, when we rolled up to the house this afternoon the car thermometer was registering 104F - ugh. Quite hot after our trip, which was mostly cool and damp.

This afternoon, I see that storms and MCSs in northern Mexico are trying to push more moist air northward into southeast Arizona, but that a battle is underway between moist and the dry air centered over northwest Mexico and southeast Arizona. At this time storms have developed over parts of Cochise County and a fairly pronounced outflow has pushed well northward into that county. Will be interesting to see how things stand tomorrow morning.
