Synopsis Drier air and building high pressure will result in less
thunderstorm activity with higher afternoon temperatures through the
weekend. Early next week the high drifts just far enough away to
allow some moisture to return, generating isolated to scattered
thunderstorms.

Discussion Radar echoes continue to diminish this evening
as conditions become more stable without the aid of daytime heating.

Storms this afternoon mostly hugged the mountains and struggled to
gain any significant organization. The 18 00z sounding revealed a
drier atmosphere compared to 24 hours ago, with precipitable water
amounts falling to 1.27" and weak disorganized cloud-layer winds.

Due to radar trends and no indication of redevelopment, pops were
adjusted down for the rest of the overnight period. Please see the
previous discussion for further details about the coming days.

Aviation Valid through 19 06z.

Few-sct cloud bases generally 8-12k ft agl. Slight chance of -shra -
tsra in the southeast corner of the state overnight, redeveloping
Saturday afternoon and favoring mountain locations. Surface winds
are light and variable through the night, settling wly-nwly Saturday
afternoon. Aviation discussion not updated for TAF amendments.

Fire weather Thunderstorm activity trends down through the
weekend, with isolated storms favoring higher terrain areas. The
pattern then becomes more favorable at the start of next week
allowing for greater areal coverage of storms. 20-ft winds remain
terrain driven at less than 15 mph, except for in and around
thunderstorms where strong outflows may occur.

Prev discussion Saturday is looking like it should be a repeat of
today in a basic sense with similar temperatures and areas of
convective development. The mid-level flow will be turning more nw
with time as the upper level high begins to build over az so there
should be some drying aloft bringing the pw values back down to
normal levels.

The northerly flow strengthens a bit Sunday with fairly high heights
which will result in further drying aloft, enough so that storms are
not in the forecast for anywhere but near the mexico border. For the
most part it will be mostly sunny and hot across the area with high
temperatures 3-5 degrees warmer than normal.

Not a significant amount of difference for Monday with very limited
convection with the upper high in the vicinity and moisture only
begining the slow increase again late in the day.

Another warmer than normal day.

Tuesday onward, the exact position of the upper level high will
determine just how active the convection is and at this time it
doesn't look very active overall with the high either overhead or
just to the east. We will not be shut down, just not overly active
either and temperatures should remain near to or a bit warmer than
average through the week.

Twc watches warnings advisories
None.

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.
