773 FXUS65 KTWC 292005 AFDTWC Area Forecast Discussion National Weather Service Tucson AZ 105 PM MST Sun Sep 29 2024 .SYNOPSIS... Above normal heat will continue well into the workweek across southern AZ. && .DISCUSSION... Breezy conditions today are contributing to strong mixing at the surface, which in turn is driving temperatures upward. While temperatures will moderate ever so slightly the next 5-6 days, we`ll still be in triple digit and near (all time) record high territory as we enter October. If you look closely enough, there is some upper level moisture available at in the far NE part of the CWA the next few days, but the odds of that producing anything measurable or impactful enough at the surface is very limited. Otherwise the long term pattern doesn`t show any signs of a reprieve from the heat, until sometime next week at the earliest. Will need to keep an eye on HeatRisk levels for the forseeable future, as we are in somewhat unchartered territory for these types of daytime highs for this time of year. && .AVIATION...Valid through 01/00Z SKC for most of the region with the exception of FEW clouds 9k to 12k ft AGL mainly NE of KTUS to the White Mountains. SFC winds ELY/SELY 10-18 kts with gusts to 25 kts through the forecast period. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...
