Weather

Continued unsettled and cooler with light precipitation focused from southeastern AZ eastward into far west TX today. A quicker/drier system appears on tap for the weekend...mainly bringing a reinforcing shot of cooler/colder air. Milder/continued dry early-middle part of next week. The large-scale pattern presently features an active storm track that will bring systems across the Southwest every 3-5 days. This will result in brief mild and dry conditions between systems and areas/periods of rain & higher elevation snow as the systems move through.  On this schedule, systems will move through the Southwest today and again over the weekend. The bulk of the moisture today looks to impact southeastern AZ eastward into west TX today. The weekend system appears to be more of a quick hitter bringing more cooler/colder air in, focused east. A northwest flow pattern looks likely to develop thereafter, with dry conditions overall...and becoming milder, esp. west. A more active period will likely ensue again around Christmas into the last full weekend of December.  

Fuels/Fire Potential

Risk for significant fire activity overall negligible for the forecast period. A more active and moist late fall/early winter weather pattern will keep fire potential low overall for the foreseeable future. Human caused fires in dormant fine fuels on warmer, winder & drier days will be the primary general concern.
