Synopsis Isolated thunderstorms may occur this afternoon near the
international border southwest of tucson. Otherwise, dry conditions
with daytime temperatures a few degrees above normal through
Tuesday. A few thunderstorms may return Wednesday mainly to southern
and eastern mountains.
Discussion Clear skies across much of southeast arizona at this
time. A few exceptions with mainly cumuloform clouds were noted via
visible satellite imagery were across south central pinal county and
near international border from douglas to nogales. Dew points at
lower elevations valid 8 am mst ranged from the mid 50s-mid 60s, and
these temps were nearly 2-4 degrees lower versus 24 hours ago.
Surface temps at lower elevations valid 8 am mst were about 2-7
degrees warmer versus this time Thursday.
21 12z ktwc sounding precip water value of 1.02 inches was down
nearly 0.40 inch versus 24 hours ago. The profile was markedly drier
above 600 mb, and a decent capping inversion existed around 650 mb.
21 12z upper air plots depicted a fast belt of westerlies across the
northern conus. Meanwhile, a weaker gradient existed in the 500-300
mb layer resulting in light to moderate westerly flow in that layer
across southeast arizona.
The 21 13z and 21 14z hrrr solutions suggest that a few
thunderstorms may develop this afternoon mainly near the
international border southwest of tucson. Any thunderstorms that
develop should end by this evening. Otherwise, dry conditions across
southeast arizona with high temps about 5 degrees or so warmer
Please refer to the additional sections for further detail.
Aviation Valid through 22 18z.
Isolated -tsra -shra mainly near international border southwest of|
ktus this afternoon. Otherwise, clear skies to scattered clouds at
8k-12k ft agl. Surface wind ely to nly 5-15 kts this afternoon, then
ely sely 8-18 kts with gusts near 25 kts late tonight into Saturday
morning. Strongest speeds expected near ktus especially 14z-18z
Saturday. Aviation discussion not updated for TAF amendments.
Fire weather Isolated thunderstorms may occur this afternoon
near international border southwest of tucson. Otherwise, dry
conditions across much of the area through Tuesday. A slight chance
of thunderstorms returns Wednesday mainly near mountains east to
south of tucson. 20-foot winds becoming mainly easterly by this
evening followed by occasional east to southeast gusts near 25 mph
late tonight into Sunday morning. 20-foot winds will be terrain
driven mainly less than 15 mph Monday into midweek.
Prev discussion 306 am mst We still have enough residual
boundary layer moisture for a few patchy fog spots this morning. A
broad westerly flow dominates in mid and upper levels with
considerable drying above 700mb. Easterlies will increase at the
surface and lower levels as a strong surface high builds in the
central plains and down the front range of the rockies over the next
24 hours. We'll continue to recirculate boundary layer moisture for
another couple of days with isolated buildups in the mountains,
however the main story will be the gusty east winds Saturday morning.
A trough digging through the region north of our area will reinforce
and deepen a drier westerly flow early in the new week, while also
keeping the rebound in temperatures in check.
By mid week we have an open pattern once again with some moisture
returning from the south. Probably just enough for a low grade
thunderstorm forecast to end the season. We'll still need to keep an
eye on the tropics well into october before transition season
patterns become more dominant.

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 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.
