079 FXUS65 KFGZ 301532 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 832 AM MST Tue Apr 30 2024 .SYNOPSIS...Warm, dry and breezy conditions continue through the rest of the week. Winder, more unsettled weather potentially returns later this weekend into early next week. && .UPDATE...Zonal flow over northern Arizona will bring a few degrees of warming today, clear skies, and afternoon breezes. A shortwave trough moving through the Great Basin on Wednesday will bring slightly stronger afternoon winds and a few degrees of cooling. && .PREV DISCUSSION /331 AM MST/...Zonal flow keeps warmer temperature and dry conditions in the forecast for today. Slight troughing on Wednesday will bring a slight cool down for the later-half of the week, but overall temperatures will remain near-normal for this time of year. Some breezier winds are also expected, but will largely be nothing to write home about as the vast majority will see gusts in the 25-35 mph range. Areas downwind of the Kaibab Plateau, Black Mesa, and Chuska Mountains will likely see the strongest gusts, where gusts up to 40 mph are possible. Heights begin to rise a bit on Friday as high pressure tries to build into Arizona. Warmer temperatures return as a result. However, this is short-lived, as guidance hints at the potential for a stronger trough to move into Arizona late in the weekend/early next week. Guidance remains in disagreement on the exact track and timing of the trough, so uncertainty remains high. Nevertheless, cooler and windier conditions looks possible, along with potentially some precipitation come Monday. At this point in time though, only a handful of members from the EPS, GEFS, and CMCE have any measurable preciptation. && .AVIATION...Tuesday 30/12Z through Wednesday 01/12Z...VFR conditions are forecast.
