Synopsis Moisture will be returning to southeast arizona this
weekend bringing a chance for showers and thunderstorms.

Thunderstorm chances will continue through at least the middle of
next week.

Discussion Morning sounding showing only 0.63 inches of
precipitable water and surface dewpoints only 50 degrees at best
on the border, lower farther north. Some mid level moisture
evident by cloud tufts in the southern sky. While mid level
moisture will be increasing today, we should remain dry and
temperatures should be able to equal or exceed yesterday's
maximums in most locations.

Forecast looks on track for increasing chances of thunderstorms
this weekend. See prev discussion for details.

Aviation Valid thru 19 18z.

Scattered clouds 8k-12k ft agl especially east of ktus this
afternoon and evening. A few -tsra may occur near the
international new mexico borders southeast of ktus tonight.

However, expected occurrence of -tsra -shra at kdug is too low to
include in the kdug taf. Expect normal diurnal wind trends less
than 12 kts into early Saturday morning. Aviation discussion not
updated for TAF amendments.

Fire weather Dry conditions today followed by a slight chance of
thunderstorms across far southeast sections late tonight. Increased
moisture will then bring scattered thunderstorms Saturday into next
week. 20- foot winds will mainly be terrain driven less than 15
mph aside from thunderstorm gusts. The exception appears to be Saturday
when an easterly component should prevail.

Prev discussion Initially, the deepest moisture is shaping up
for chihuahua and new mexico Saturday. Sunday and Monday will see
that favorable h7 theta-e axis shift deeper into our area as a
high center reconsolidates over texas downstream, and a weak low
sags into california upstream. We should see decent thunderstorm
coverage Sunday afternoon into Monday evening or Tuesday
afternoon.

After that it gets tricky. The moisture will still be here and or
nearby, but features become more subtle. The main factor is the
weakness in the flow upstream and it's positioning. If it's too
close then we likely wrap in some dry air under it, with the
deepest fetch of moisture through new mexico. For now the best we
can do is just throw in a chance of mainly afternoon and evening
thunderstorms, something close to climatology.

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.
