Area Forecast Discussion National Weather Service Flagstaff AZ 930 PM MST Thu Dec 12 2019
SYNOPSIS. Dry and mild conditions will continue through Friday. A cold front will cross the region this weekend bring gusty southwest winds and a chance of snow and rain showers. Expect much colder daytime temperatures Sunday through Tuesday.
UPDATE. The weak ridge off the west coast is keeping northern Arizona in a zonal to northwesterly flow aloft that is advecting in upper level moisture in the form of thin clouds. Adjusted the forecast to account for the increased high clouds overnight and moderated the morning low temperatures accordingly. Otherwise, no changes are needed to the earlier forecast. Look for the next trough to pass to the north late Saturday through Sunday with a well organized cold front to slowly work its way north to south through the region beginning Saturday evening along the Utah border and not reaching the southern boundary until Sunday evening. This will bring a 20 to 25 degree drop in the daytime temperatures by Monday from Friday's highs.
PREV DISCUSSION /228 PM MST/. It's a warm mid-December afternoon across northern Arizona, with temperatures currently running around 5 to 15 degrees above normal. Similar weather is expected on Friday as a weak ridge of high pressure remains overhead.
We will see conditions change over the weekend as a cold front drops south toward the state. Ahead of the front, gusty winds will develop northeast of the Mogollon Rim overnight Friday into Saturday. These winds will become more widespread across the area on Saturday as the pressure gradient tightens. Wind gusts of 30-40 mph will be possible, with the strongest speeds along and north of the Mogollon Rim. Gusty winds will continue Saturday night into Sunday, especially across the eastern Rim and White Mountains where higher gusts up to 50 mph are not out of question. Winds will shift to a northerly direction later Sunday behind the front and remain breezy into early next week.
As for precipitation, expect showers to develop Saturday afternoon, mainly over the higher terrain. More widespread shower activity will occur overnight Saturday into Sunday as the cold front pushes south through the region. Snow levels will initially be around 6,000-7,000 feet before falling to as low as 4,000 feet on Sunday. Snow accumulations will be highest over far northern Arizona including the Kaibab Plateau, Black Mesa, and Chuska Mountains where generally 2-6 inches of snow is possible. Moisture will be more limited to the south with up to an inch in Flagstaff, and little if any accumulation south of Interstate 40. Showers will wind down from northwest to southeast Sunday night.
A cold and dry airmass will move into northern Arizona behind the front through early next week. Temperatures will struggle to get out of the low to mid 30s over the higher terrain Sunday and Monday. Breezy northerly winds will make it feel even colder. A gradual warming trend and dry conditions are expected through the remainder of the forecast period.
AVIATION. For the 06Z package . Light winds and VFR conditions under occasional high clouds will prevail for the next 24 hours. Aviation discussion not updated for TAF amendments.
FIRE WEATHER. Dry and mild weather will continue Friday. An approaching cold front will bring gusty southwest winds and increasing chances for rain and snow showers on Saturday.
Sunday through Tuesday . The cold front will cross the region on Sunday, with continued chances for rain and snow showers mainly north of I-40. Behind the front, expect much colder temperatures and breezy northerly winds into early next week.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
