Synopsis Dry westerly flow will shut down thunderstorm chances
into Friday. A moisture increase from the south will gradually
bring isolated to scattered thunderstorms back to the region this
weekend and especially early next week. High temperatures within
a few degrees of normal will prevail.

Discussion Generally clear skies over SE az this morning
although mid high cloudiness continues to stream NE from leftover
storm complex in mexico as mentioned in previous discussion
section below. Precipitable water on this morning's sounding
showed 0.77 inch, still below normal. Should be enough mid level
moisture later today though to result in buildups over the
mountains, especially east of tucson. However there is still not
enough moisture or instability in the atmosphere for thunderstorms

Temperatures this morning are running 1 to 4 degrees warmer than
this time yesterday. With considerable sunshine, we should be able
to eclipse Wednesday's highs and tucson will approach the 100
degree mark. That would be the first occurrence of 100 or warmer
at the airport since the 11th of august.

Current forecast of a ramp up in moisture and thunderstorm
chances into early next week looks on track. No adjustments needed
for now.

Aviation Valid thru 18 18z.

Mainly clear skies will prevail through the period. Expect normal
diurnal wind trends less than 12 kts. Aviation discussion not
updated for TAF amendments.

Fire weather Dry westerly flow aloft will continue into Friday.

Isolated to scattered showers and thunderstorms will then return
this weekend into early next week. 20-foot winds will generally be
terrain driven at less than 15 mph apart from any thunderstorm

Prev discussion A moderate westerly flow continues with well
below average moisture for mid august. Even international border
areas were showing dew points in the 40s yesterday. Precipitable
water values are ranging from .6 to .8 inches across the area,
with below average values around 1 to 1.3 inches even in southern
sonora. Southwest chihuahua and especially sinaloa were pretty
active yesterday, with the monsoon pushed back deeper into mexico.

It's too early to call it quits, and that trend will reverse over
the next 72 hours as northern portions of mexico get active
again. The complex in northern sinaloa will help push deeper
moisture through sonora, staging in southern sonora and western
chihuahua tomorrow and then northern portions of the those states
Friday. We'll be picking up a southerly component to our flow as
this happens, with weak troughiness to our northwest and some
reconsolidation of the ridge to our east. By this weekend, all of
these trends will have pushed deeper moisture back into our corner
of the state along with new mexico. After the ramp-up over the
weekend, we should be in good shape for storms the first half of
next week.

Twc watches warnings advisories None.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
