Synopsis Dry and mild through Thursday. Another system will
bring a chance of valley rain and mountain snow late Thursday
night into Friday, especially northeast of tucson. Strong warming
over the weekend will give way to another system early next week.

Plenty of cool air, but it may be on the dry side this far south,
except for a few snow showers in the mountains.

Discussion Upper air flow pattern currently consists of a weak
shortwave ridge across the area. Still plenty of thin cirroform
cloudiness, especially south and east of tucson. Based on latest
satellite trends, ongoing forecast of skies tending to become mostly
clear overnight looks good with near normal temperatures. Thursday
is shaping up to be a nice dry day with westerly flow ahead of the
next system with temperatures several degrees warmer than today. No
changes to the forecast this evening. See previous discussion for
additional information.

Aviation Valid through 18 06z.

Mainly sct clouds AOA 18k ft agl through the period with occasional
bkn coverage. Terrain driven wind at less than 10 kts will occur
overnight into Thursday morning becoming W NW wind less than 12 kts
Thursday afternoon before diminishing to less than 10 kts again
Thursday evening. Aviation discussion not updated for TAF amendments.

Fire weather Dry conditions will prevail into Thursday evening.

The next chance of valley rain and mountain snow occurs from tucson
east northeast Thursday night through Friday. Dry conditions are
expected Saturday into Tuesday morning, with a slight chance of
showers in the white mountains during the day Tuesday. Gusty
northwest winds of 15 to 20 mph will occur Friday, mainly from
tucson eastward and especially in the upper gila river valley.

Elevated east to southeast winds may occur Saturday and Sunday.

Breezy west to southwest winds return Monday afternoon. Otherwise,
20-foot winds will be under 15 mph.

Prev discussion A dirty zonal flow is bringing layered cirrus
level cloud cover across in the westerlys. Partial clearing from the
west in the morning hours may allow some overnight lows to dip a
little lower than today.

A system currently just off the northern california coast will try
to split some energy into lower latitudes, however with the strong
ridging off the southern california baja coast we will probably
see a glancing blow for our area. Best dynamics and moisture couplet
just north and east of our area with a sharp gradient of precip
chances (low south to high north). Tucson on the edge of things in
the 20 to 30 percent chance range, and much higher chances near the
mountains and north to northeast. QPF values fairly low, but could
end up with a couple of inches of snow in the mountains (favoring
graham and greenlee counties).

A strong ridge will then push our temperatures 8 to 10 degrees above
average by Sunday. Ensembles and ensemble means continue to show a
dominant ridge position just west of our area early next week, with
a storm track north and east of us. Even if moisture is limited for
a drier trajectory storm Tuesday, we should manage plenty of cold
air advection to push temperatures back to several degrees below
average.

Twc watches warnings advisories None.

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.
