TUCSON - Temperatures are on the rise for the next few days before our first strong fall cold front.
A warming trend started today as an area of high pressure began to nudge its way into the western states, according to Meteorologist John Patrick. Daytime highs were able to climb to 87 for the Old Pueblo Sunday and we'll continue the warm up through midweek. Temperatures peak as you hit the polls on Tuesday with a near record forecast high of 90. Sunny skies, clear nights and relatively light winds will prevail through this period.
Big changes are on the horizon for late in the week as we track our first significant fall system. The biggest effect this low will have on southern Arizona is a huge a temperature swing. Daytime highs will drop from 90 on Tuesday to the 60s by this upcoming weekend. Breezy to windy conditions will also accompany this storm system starting as early as Thursday and lasting through Saturday. Models still keep the bulk of the precipitation to our north but just enough moisture should remain to support a slight chance of valley rain and mountain snow Friday and Saturday.
