A Look At January

 
Snow cover in Summerhaven on morning of January 30th.

January was a very quiet weather month here. Noted in my weather log: a light sprinkle and east winds to 30 mph afternoon of the 8th; morning low of 22 F on the 12th; afternoon showers and 0.13" on afternoon of 29th. Total of 0.13" was a tie for 8th driest January since I started records in 1999.

Yesterday's high of 86 F tied the record set back in 1925.

It's Groundhog Day

Punxsutawney Phil saw his shadow this morning, so he's predicting six more weeks of winter. But, there's been very little winter here in Tucson so far.
