Synopsis We'll see a strong warming trend this weekend with
unseasonably warm daytime temperatures during the upcoming week.

Expect dry conditions across the area most of next week with the
exception of a few light showers possible southeast of tucson
Sunday. We may also see a few thunderstorms in eastern mountains
late in the week.

Discussion The upper pattern this evening is defined by a weak
upper low near 31n 120w (sw of san diego) and a shortwave ridge
extending from the sonora chihuahua border nnw into NW arizona.

Ridge axis currently across southeast arizona with plenty of high
clouds on the backside of this feature spilling across our neck of
the woods.Look for the thicker mainly high clouds to track east late
this evening and overnight.

The weak upper low is progged to open up and weaken as it tracks
across southeast arizona through the day tomorrow. Any moisture
precip associated with this feature will likely remain to the
south and southeast of our area in mexico. This scenario is well
handled with the inherited forecast... So no updates will be
necessary.

Aviation Valid through 23 06z.

Bkn-ovc clouds above 20k ft agl thru 22 06z, then few-sct clouds
above 20k ft agl. Normal wind trends generally less than 10 kts.

Aviation discussion not updated for TAF amendments.

Fire weather Warmer temperatures are expected through next
week, with readings topping out about 10 degrees above normal by
early next week. It will remain dry in most locations, with just a
slight chance of showers along the new mexico border Sunday. A few
thunderstorms may also occur late next week over far eastern areas,
especially the white mountains. Any lightning would enhance fire
initiation concerns and gusty outflows may also occur. Otherwise,
winds will generally be light and terrain driven through mid next
week, with the usual afternoon gustiness due to strong daytime
heating.

Prev discussion The strong low that generated our winds over the
past couple of days is now well east of the area in the central
and southern plains. A weak westerly flow is taking it's place
with some ridging leading to a rapid warming trend over the
weekend. Temperatures are running 5 to 10 degrees warmer than
this time yesterday, with another 5 or 6 degrees of warming
expected Sunday.

Not as high and dry as we usually are behind a system like that
though. A weak low just off the northern baja coast is dirtying up
the base of the ridge and incorporating some mid and high level
tropical moisture to draw clouds into the area. As it opens up and
pushes across northern mexico tomorrow and tomorrow night, it
will generate some showers in sonora and chihuahua. We could see
a light shower or two just over the border into southeast
arizona, but most of the area will be dry.

Additional height and thickness increases to start the work week
will push temperatures to around 10 degrees above average by
Tuesday. It's still going to be dirty ridging with weak impulses
embedded in the weak westerly flow Wednesday into Friday. Add in
some interesting 700mb theta-e trends through central and
northern mexico, and into new mexico and texas. We might manage a
couple of thunderstorms near eastern mountains the second half of
the week, with an emphasis on Friday and Friday night. A dry
lightning scenario would not be cool considering dangerous
potential wildfire conditions.

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.
