Area Forecast Discussion
National Weather Service Flagstaff AZ
149 PM MST Sat Nov 28 2020

.SYNOPSIS...Fog and low clouds are clearing this afternoon in 
eastern parts of the Little Colorado River valley. Another round
of patchy fog is possible early Sunday morning for similar areas.
Dry weather this weekend will last into next week. A cool down is
possible by Wednesday with increasing wind speeds.

&&

.DISCUSSION...Limited periods of patchy fog tonight will give way
to quiet weather across northern Arizona through Tuesday. A dry 
frontal passage by Wednesday morning could create a colder period 
later next week with stronger northerly winds.

Today and Sunday...Melting snowfall and residual boundary layer 
moisture in the eastern Little Colorado River valley have created 
the continued overcast skies and patchy fog near St. Johns, 
Petrified Forest National Park and Woodruff. Increasing surface 
temperatures and breaks in the sky cover though are greatly 
helping to decrease the fog coverage and is expected to be out of 
the area by late this afternoon. Although, patchy fog is 
reintroduced into those same regions after 3 AM MST on Sunday. 
Coverage of patchy fog is expected to be less than what occurred
today.

The northwest to southeast oriented surface gradient will tighten
overnight across northern Arizona and result in increased
northeasterly winds on Sunday. Sustained winds of 5-15 mph are
likely with a few locations seeing afternoon wind gusts up to 20
mph, mainly along the Mogollon Rim and across the Coconino Plateau.

Monday and Tuesday...Upper air pattern will continue to bring dry
northwesterly flow over northern Arizona Monday and Tuesday. 
Temperatures on Monday and Tuesday are likely to be the warmest of
the upcoming work week with daytime temperatures near normal.

Wednesday to Friday...A dry cold front is progged to cross over 
Arizona by Wednesday and result in gusty north to northeast winds 
building over the region for Wednesday and Thursday, along with 
decreasing temperatures. At this point, any moisture looks to stay
well into New Mexico so the forecast calls for a dry week ahead. 
Lighter wind and warming temperatures by Friday.

.AVIATION...For the 00Z package...Primarily VFR conditions over 
the next 24 hours. Visibility continues to improve north of a line
from KSOW to KSJN in the eastern Little Colorado River valley.
