Synopsis Very warm afternoon temperatures and dry
conditions will persist through Friday. A storm system will then
move across the area this weekend, resulting in much cooler
temperatures, gusty winds and a chance of valley rain and mountain
snow. High pressure aloft will build back across the area next week
for a return to dry and warmer conditions.

Discussion Ir satellite imagery revealed mostly clear conditions
across most of arizona with some scattered cirrus beginning to
stream in across western portions of the state. A ridge of high
pressure aloft will move into the region from the west today,
resulting in a brief warm up through Friday. Afternoon temps on
Friday are expected to top out 8-12 degrees above mid-january
averages.

The warm temperatures will be fleeting as a deep trough of low
pressure moves into the western CONUS Friday night. As the trough
progresses eastward, there will be a chance of valley rain and
mountain snow Saturday night into Sunday morning along with gusty
southwest winds. In addition, much colder temperatures will occur
both Saturday and Sunday, generally a 15 to 20 degree drop compared
to high temperatures forecast to occur Friday. Much colder overnight
lows are anticipated as well, with freezing temperatures possible
across the tucson metro Sunday and Monday mornings.

At this time, the fast moving system will be out of the state by
Sunday afternoon, and precip accumulations should remain fairly
light. Valley locations will generally see less than 0.10 inches,
while the mountains could see up to 0.25 inches of liquid,
especially in the white mountains. Although snow levels are expected
to drop to around 3500 ft by Sunday morning, the majority of precip
should be over by then. Snowfall totals by Sunday afternoon in the
mountains will be up to 1 inch in the catalina, rincon and
chiricahua's, and up to 3 inches in the white mountains.

Dry conditions and zonal flow advect into the region Monday with
temperatures returning to near average levels. The warmup will
continue into the middle of the week with ridging in control by
Wednesday with above average temperatures.

Aviation Valid thru 19 12z.

Skc-few clouds above 20k ft agl this morning, becoming bkn in the
afternoon and evening. Surface wind east to southeast mainly less
than 12 kts through the period. Aviation discussion not updated for
taf amendments.

Fire weather Dry conditions through Friday. A storm system will
then move across the area Saturday, resulting in much cooler
temperatures, gusty southwest winds and a chance of valley rain and
mountain snow. Dry conditions will return Sunday into next week.

Gusty northwest winds will impact the upper gila valley, including
safford, Sunday. Otherwise, terrain driven winds mainly less than 15
mph will occur early next week.

Twc watches warnings advisories None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
