Synopsis A storm system moves across the area today with much
cooler temperatures, a few showers and an isolated thunderstorm
mainly northeast of tucson. Cold morning temperatures are possible
Tuesday morning for valleys east of tucson. Another weak storm
system brings a chance of showers and cooler temperatures to the
area on Wednesday. Expect a gradual warming trend into the weekend
with temperatures approaching normal.
Discussion Cloudy across the area this morning with showers or
sprinkles approaching from the west. Hrrr is handling the
situation quite well showing an area of light rain showers
passing through tucson later this morning. Hrrr and other guidance
shows the line of showers sprinkles could reach nogales, but
confidence is rather low. The best chance remains mainly north and
east of tucson.
Today: breezy to windy conditions area wide with patchy areas of
blowing dust for portions of cochise county where the strongest
winds should occur. Cloud cover may act to keep mixing down,
however as the frontal bndry moves through any shower activity
should help with mechanical mixing of stronger gusts to the
surface. The best shower and or thunderstorm activity will occur
mainly in eastern pinal, graham and greenlee counties but can't
rule out some activity for eastern pima county this morning. Much
cooler with high temperatures running 15 to 25 degrees below
normal. Later this morning into early afternoon will be the best
chance for snow showers in the white mountains. A dusting to a
slushy inch or two will be possible at the highest peaks above
Monday night into Tuesday morning: with a colder air mass over the
area record or near record low temperatures are possible,
especially across cochise county with the coldest valleys
potentially seeing lows in the upper 20s to the lower 30s.
Confidence remains low to moderate, but still think the freeze
watch looks good. No changes were made at this time as later
shifts will need to determine if to upgrade to a warning. The best
chance for freezing or near freezing temperatures would be the
sulphur springs valley and portions of NE santa cruz county.
Tuesday: zonal flow with the area between two weather systems.
Gusty afternoon winds will still be around with high temperatures
6 to 12 degrees warmer than Monday.
Wednesday: system #2 will bring another round of gusty winds, well
below normal temperatures and a slight chance of showers and a
few thunderstorms. Confidence remains moderate at this time as
guidance continues to waffle, but ensemble support still is|
sufficient for mention of shower activity. Confidence is high for
gusty winds and cooler temperatures.
Thursday thru Sunday: dry with gusty afternoon winds under
southwest flow aloft with upper level trofiness remaining over the
west coast. Daytime temperatures will be warming but remaining
below normal. Daytime temperatures will gradually climb to around
90s degrees for many lower desert valleys.
Aviation Valid through 21 12z.
Skies generally sct-bkn mainly 4-8k ft bkn AOA 15k ft agl through
this afternoon then skies clearing this evening. Isolated -shra -
tsra ktus eastward through 21 00z. Surface winds southerly 5-10kts
then increasing and becoming wly at 15-25 kts with gusts up to 35
kts late this morning into this evening. Strongest winds will be
east of ktus including kdug. Wind easing to less than 10 kts aft
21 03z. Aviation discussion not updated for TAF amendments.
Fire weather An abnormally strong and cool weather system will
move through the region today. This will result in continued breezy
to windy conditions with the strongest winds east of tucson.
However, increased moisture including a slight chance of a shower
and thunderstorm (mainly tucson eastward) and much cooler
temperatures, rh levels will be above critical levels. The pressure
gradient will be tight on Tuesday ahead of another system moving in
for Wednesday. Thus, windy conditions continue Tuesday with local
critical wind and rh thresholds being met for brief periods Tuesday
As the next system moves in on Wednesday, the winds will remain
elevated, however the rh values will once again increase above
critical levels. Beyond that an upper low trough will remain near
the west coast which will keep temperatures below normal but the
atmosphere will dry out with lower rh values and more typical
afternoon breezes each day into next weekend.
Climate Record or near record low temperatures are in the
forecast Tuesday morning, mainly across cochise county.

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.
