Mike explains what Graupel is which is timely since it fell on his deck yesterday.  Hard Freeze Warning this morning and early morning tomorrow too but a slow warming trend will continue through the weekend.  Another storm early next week?  Mike talks about that possibility and shows us snow and cold temperatures in Texas, New Mexico and Missouri in this morning’s Coffee and a Forecast.

Tucson Weather Coffee and a Forecast for Wednesday, February 3, 2011

Already a record cold start to a record cold day in Tucson. Snow and freezing rain possible today and tonight for places like Houston and Corpus Christi. Mike has details on this amazing cold outbreak.



The Forecast Keeps Getting Colder!

The dewpoint has plunged and overnight lows are going down with it.   Another surge of cold air is heading this way to reinforce the cold air in place.  With the drier air, we actually got colder last night than expected.  Tucson got down to 25 officially this morning.  Gusty winds should relax overnight in the valley’s of southeastern Arizona allowing temperatures to plummet even more tonight.  The National Weather Service has already issued a Hard Freeze Warning for tonight and tomorrow night and now they have dropped the expected lows for both overnight periods.  The revisions are below.  If this comes true, Tucson will set two record lows, both in the upper teens!  Tomorrow’s high is now predicted to only be 38.  If that comes true it will be second coldest high temperature ever in the 118 years they have been keeping records in Tucson.  The coldest was 37 on February 6, 1899!  Amazing.
