949 FXUS65 KFGZ 202122 AFDFGZ Area Forecast Discussion National Weather Service Flagstaff AZ 222 PM MST Mon May 20 2024 .SYNOPSIS...Strong winds will diminish this evening, with a few sprinkles or isolated light showers possible over eastern Arizona. Expect dry, breezy, and mild weather through the rest of the week with near normal temperatures. && .DISCUSSION...Very windy across the northland today, particularly in the corridor from Two Guns to Winslow where gusts in excess of 60mph were recorded this afternoon. Some very light precipitation is moving through Gila, southern Coconino and Navajo Counties, but only a hundredth or two have been recorded so far and don`t expect meaningful accumulations at this time. The Red Flag Warning and Wind Advisory will stay in effect into this evening. The axis of the trough responsible for the strong winds and light showers will pass through Arizona this evening, with decreasing clouds and lighter winds overnight. With very dry air in place, the temperatures have the potential to get quite cold tonight (and Tuesday night) with the light winds, and we`re likely to see freezing temperatures in a couple of our high-elevation cold spots. The rest of the week will be dominated by low-amplitude troughing or nearly featureless zonal flow. Expect dry, breezy weather with seasonable temperatures through Friday. We`ll be keeping our eye on Friday and Saturday where the winds may be strong enough to bring critical fire weather conditions back into our area. && .AVIATION...Monday 20/18Z through Tuesday 21/18Z...Mainly VFR conditions. This afternoon, southwest winds sustained at 20 to 30 knots will gust past 40 knots north of a KFLG-KSOW line. Winds will remain a bit weaker elsewhere. Blowing dust may reduce visibility at times around KINW. A few showers are possible before 06Z which could kick up erratic winds locally. Expect light winds and clear skies overnight. OUTLOOK...Tuesday 21/18Z through Thursday 23/18Z...VFR conditions and west to southwest winds at 10 to 20 knots gusting 20 to 30 knots each day. && .FIRE WEATHER...This afternoon through Wednesday...Critical fire weather conditions will end this evening as strong southwest winds subside. A few showers are possible this afternoon and evening but wetting rains are not anticipated. Very dry conditions will resume tomorrow and Wednesday along with southwest breezes at 10 to 20 mph. Expect minimum relative humidity values of 5 to 15 percent each afternoon and decent recoveries overnight. Thursday through Saturday...Dry conditions continue with near zero chance of rain. Southwest winds are forecast each day, sustained at 15 to 25 mph with gusts of 25 to 35 mph. Expect minimum relative humidity values of 10 to 20 percent each afternoon and decent recoveries overnight. && .FGZ WATCHES/WARNINGS/ADVISORIES...
