Synopsis A low pressure system will bring a chance of showers
mainly east of tucson through Tuesday night. Expect strong gusty
winds Tuesday and cooler temperatures. Dry conditions with a warming
trend will occur Wednesday into Thursday. The next system will bring
another chance of showers mainly northeast of tucson Friday through
Sunday.

Discussion Latest WV imagery depicts the upper low across
northern arizona early this morning. A surface cold front now
located just west of tucson will continue to sweep east-southeast
this morning and will usher in cooler temperatures today. Latest
kemx radar is depicting a broken line of showers with even a few
embedded heavier showers including a few lightning strikes along the
front and these will continue to move eastward. The showers have
developed further south/west than earlier expect so have expanded
the slight chance pops south and westward accordingly including the
tucson metro early this morning. Any showers in tucson will end
shortly after 12z. As the upper low drops towards the white
mountains and the new mexico border by midday, the best moisture
will be located across graham, greenlee and northern cochise
counties where a chance of showers will persist this afternoon with
a slight chance of thunderstorms continuing as well. Snow levels
will remain at about 7000 feet with an inch or two possible mainly
in the white mountains. The other main story with the upper low will
be the strong pressure gradient resulting in gusty winds,
particularly across the upper gila river valley including safford. A
wind advisory is in effect for much of graham, cochise and southern
greenlee counties from late this morning into the early evening.

There will also be fire weather concerns, especially across southern
cochise county where a red flag warning is in effect. See fire
weather discussion below for more information.

As the upper low pushes east tonight into Wednesday, the chance of
rain/snow showers will exit the white mountains overnight with dry
conditions prevailing Wednesday. The northwesterly flow will still
result in some breezes east of tucson on Wednesday afternoon with
temperatures near seasonal normals. Shortwave ridging will peak on
Thursday ahead of the next system with Thursday being the warmest
day of the week with highs about 6 to 9 degrees above normal.

Another stronger/deeper upper low will start to impact the area on
Friday as it moves into the northern part of the state, then into
new mexico on Saturday. 00z models are in good agreement regarding
the strength of the system but still some minor discrepancies
regarding the track and timing. The bulk of the moisture should
remain well to our north overall with strong and gusty winds
impacting much of southeast arizona on Friday. The upper low will
still be close enough for a chance of showers mainly northeast of
tucson Friday and Saturday. A few residual rain/snow showers will
remain possible for the white mountains on Sunday with dry
conditions prevailing elsewhere as the storm system moves away.

Otherwise, expect below normal temperatures to return Friday and
Saturday with modest warming on Sunday. It will remain dry on Monday
as well with continued warming temperatures.

Aviation Valid through 29/12z.

Isolated to scattered -shra/-tsra with CIGS 8k-12k ft
agl... Diminishing from west to east by this evening. Otherwise, sct-
bkn clouds 10k-15k ft agl. Surface wind wly/nwly 12-25 kts with
gusts to near 35 kts today. The strongest speeds will be east of
ktus. Aviation discussion not updated for TAF amendments.

Fire weather There is a chance of showers into tonight,
especially across graham and greenlee counties. Farther south in
southern fire weather zones 151 and 152, windy conditions and low
humidities will result in critical fire weather conditions today.

Therefore, a red flag warning has been issued from 11 am to 7 pm for
the southern portions of fire weather zones 151 and 152. Afternoon
breezes will continue Wednesday and Thursday along with warmer
temperatures. Another weather system will then move in late Friday
with gusty winds. This system will also bring a chance of showers
mainly northeast of tucson Friday through Sunday.

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.
