Synopsis Warmer weather has established itself across southeast
arizona as temperatures hover closer to normal for this time of year.

Generally dry conditions will persist, although a slight chance for
precipitation develops Tuesday evening over the white mountains.

Discussion A weak shortwave moving east across southern
california in the southern stream will result in an increase the
cirrus clouds over the area tonight with thesescattered high clouds
continuing through much of Friday. The easterly gradient across the
region has weakened significantly resulting in light winds this
evening area wide for the first time in several days. The clear skies
at the moment and the light winds have allowed the temperatures to
drop faster than in previous nights, however the approaching high
level moisture will slow that drop later tonight. All that to say a
nice mid-november night is in store. Only made some minor tweaks to
the temperatures and sky cover for the overnight forecast.

Aviation Valid through 17 06z.

Sct clouds above 20k ft agl spreading in from the west tonight and
remaining through the remainder of valid period. Surfaces winds
generally remain below 12 kts through the forecast period. Aviation
discussion not updated for TAF amendments.

Fire weather Winds becoming light and diurnal in direction tonight
with more typical diurnal wind regime Friday through the weekend.

East winds return briefly Monday into Tuesday. Relative humidities
will remain low until a modest increase occurs starting Tuesday. This
also brings a slight chance of precipitation to the mountains and
higher terrain for Tuesday night.

Prev discussion issued 332 pm mst Thu nov 15 2018
after several cool and breezy days, temperatures have warmed 5-10
degrees from 24 hours ago. Skies are generally clear, with a few
bands of cirrus approaching western arizona. The strong easterly
winds have also come down as the surface gradient slackens, allowing
a return to typical diurnal flow. This lighter wind regime looks to
continue throughout the forecast period.

A fairly innocuous pattern remains through the coming days as dry
westerly flow dominates. This provides mild weather with passing
high-level clouds that thicken from time to time through the
weekend. On Monday next week, a progressive closed 500mb low
approaches the southern california coastline. However, model
solutions differ slightly as it comes ashore, nearing arizona on
Tuesday. The 12z deterministic GFS has the most aggressive scenario
maintaining the closed low, which results in a higher probability of
precipitation across the eastern portion of the forecast area
Tuesday night. Conversely, the ensemble guidance and ECMWF weaken
this feature into an open wave that produces a generally dry
forecast. For now, the forecast is assuming a slight chance of
showers around the white mountains.

Ridging or westerly flow returns on Wednesday into Thursday allowing
for dry weather area wide. Temperatures show little variation
through the entirety of the forecast, maintaining close to seasonal
normals.

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.
