What forecasters said that day
The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Flagstaff, AZ wrote its last area forecast discussion before this red flag warning went out at Apr 10, 4:35 AM MST, 1 hour 30 minutes earlier.
Area forecast discussion, Apr 10, 4:35 AM MST, 1 hour 30 minutes before
Area Forecast Discussion National Weather Service Flagstaff AZ 435 AM MST Tue Apr 10 2018 .SYNOPSIS...A warm day with generally light winds is expected today as high pressure moves through the state. Southwest winds will begin to increase Wednesday, as a major low pressure system approaches the west coast. Winds will stay gusty in places Wednesday night, before really increasing on Thursday as a cold front moves into Arizona. This will be a prolonged period of strong winds and dangerous fire weather conditions, possibly lasting in Friday. Much colder air will move into the area Thursday and Friday, but precipitation chances will be very low. High pressure returns over the weekend, with warming temperatures. && .DISCUSSION...A weakening s/wv ridge will quickly cross the state today, ahead of a major trough taking shape in the eastern Pacific. Hghts support temperatures about 10 degrees above normal, maybe a little higher as mixing develops this afternoon. By Wednesday, a significant s/wv at the southern end of the trough approaches central California and winds aloft increase. Hghts are still high enough to support above normal temperatures, but winds and dry surface conditions will be the bigger story. Deeper mixing and dewpoints in the single digits to middle teens will lead to dangerous fire weather conditions and gusty southwest winds. Both Wind Advisories and Red Flag Warnings have been issued. Gusty winds will continue Wednesday night over higher terrain and many areas will see only minor decreases in wind speeds. Thursday will be the windiest day as the trough moves through the Great Basin. Dry surface conditions will persist, despite rapidly cooling temperatures, and wind speeds will easily exceed Wind Advisory criteria most places. Eastern Arizona may see High Wind criteria as the front will reach this area later in the day. A variety of wind products have been issued for Thursday, as well as another Red Flag Warning. A trailing s/wv will dive south Thursday night and Friday, with winds switching to the north and staying strong through Friday afternoon, possibly even into Saturday Finally, a s/wv ridge develops for next weekend, only to yield to another strong wind potential by early next week. Precipitation will be hard to come by with this system due to the very dry air. Places along the Utah border will have the best shot on Thursday, with a few showers possible along the cold front and trailing mid-level instability Thursday night and Friday. && .AVIATION...For the 12z package... VFR conditions will prevail over the next 24 hrs. Winds light and variable, becmg SW 10-20 kts after 17Z and dropping back to light and variable after 02Z. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Expect very dry conditions today with locally breezy winds and warm temperatures. Southwest winds will increase Wednesday afternoon and a Red Flag Warning has been issued for areas along and north of the Mogollon Rim. Thursday through Saturday...A dry cold front will bring stronger southwest winds Thursday. Although temperatures will be cooler, very dry conditions will continue the threat for critical fire weather. A Red Flag Warning has been issued for all of northern Arizona on Thursday. Cold and dry weather will follow Friday, with gusty northwest winds. Continued dry and cool conditions Saturday, with breezy northerly winds. && .FGZ WATCHES/WARNINGS/ADVISORIES...
