Synopsis Isolated snow showers ending in the white mountains
later tonight. Dry conditions will prevail Tuesday into early next
week. Much cooler temperatures will occur Tuesday before a warming
trend begins Wednesday. Expect above normal daytime temperatures
across much of the area by Thursday and continuing into next Monday.
Discussion Ir satellite imagery and surface observations depicted
clear skies across western pima county, and southeast of tucson
across much of cochise county. Meanwhile, a band of fairly thick
lower and mid-level clouds extended from near the tucson metro area
northeastward into the white mountains. This band of cloudiness was
along and behind a cold front that stretched from north-central new
mexico southwestward to near sierra vista and nogales.
The 22 00z upper air plots depicted a trough over the intermountain
west, and a mid upper trough axis extended from eastern montana
southwestward into southwest arizona. 22 00z ktwc sounding total
precip water value was a paltry 0.37 inch. Interesting to note the
very fast flow aloft: 45 kts near 700 mb; 90 kts as low as 600 mb;
and nearly 130 kts around 250 mb.
The 22 00z nam GFS depict the mid upper trough axis will move
rapidly eastward and extend from central nebraska southwestward to
near EL paso by midday Tuesday. Several hrrr solutions as well as
the nam12 GFS suggest that isolated snow showers should occur across
the white mountains the rest of tonight. However, any snow
accumulations will be quite, generally an inch or less above 7000
feet. Given the aforementioned cloud band, would not be surprised to
have some flurries also occur on mount graham and perhaps the
highest peaks of the catalina mountains. Any precip is expected to
be northeast to east of this forecast area around daybreak Tuesday.
Otherwise, gusty west to northwest winds continue as of 8 pm mst.
However, speeds have diminished somewhat versus earlier today, and
will continue to diminish later tonight. Gusty northwest winds
should return Tuesday afternoon, especially east of tucson. High
temps Tuesday will range about 15-20 degrees cooler versus this
afternoon. A warming trend begins Wednesday with above normal
daytime temperatures across much of the area by Thursday and|
continuing into early next week as dry conditions prevail.
The inherited official forecast was updated for the removal of the
wind advisory east of tucson. Otherwise, no other updates are
warranted at this time. Please refer to the additional sections for
Aviation Valid through 23 06z.
Isolated -shsn ending in the white mtns northeast of ksad around
daybreak Tuesday. Otherwise, west of ktus expect skc-few clouds
above 15k ft agl. Ktus vicinity eastward, sct-bkn clouds 6k-10k ft
agl becoming few clouds 10k-15k ft agl late Tuesday morning into
Tuesday evening. Surface wind wly nwly 8-18 kts with gusts to 25 kts
diminishing late tonight. Surface wind Tuesday afternoon and evening
nwly 10-20 kts with gusts near 25 kts. Strongest speeds east of
ktus. Aviation discussion not updated for TAF amendments.
Fire weather Isolated snow showers across the white mountains
ending later tonight. Dry conditions will prevail Tuesday into early
next week. Gusty west to northwest winds diminishing later tonight.
However, gusty northwest winds returning Tuesday afternoon and
evening, especially east of tucson. 20-foot winds Wednesday into
this weekend mainly under 15 mph.
Prev discussion 214 pm mst Isolated snow showers over the white
mountains tonight into Tuesday morning. Thereafter, expecting
clearing skies Tuesday afternoon into Thursday. For Tuesday night
into Wednesday morning those clear skies, low dewpoints and light
winds will allow temperatures to cool nicely with near or slightly
below freezing temperatures in the tucson area and some of the lower
deserts. Quite a bit colder further east as usual.
Thereafter, the SW part of the country will be under dry NW flow
with heights and thicknesses gradually rising which will allow for
warmer afternoon temperatures and generally mostly clear skies
through the weekend.
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. 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.
