Area forecast discussion 
National Weather Service Phoenix Arizona 
245 PM MST Tuesday Jun 18 2013 


Synopsis... 
strong high pressure combined with persistent southwesterly flow 
will keep temperatures slightly above normal through the weekend. 
This will result in dry weather and persistent clear skies across 
all of southeast California...southwest and south central Arizona. 


&& 


Discussion... 
tonight through Friday... 
a rather large and energetic low pressure system will continue to 
move slowly into the Pacific northwest through Friday. Far removed 
at our latitude...dry westerly flow of warm subsident air will 
dominate. Little change in temperatures are also forecast this week 
with readings near or slightly above normal...I.E. 104 to 108 degree f 
on the lower deserts. 


Saturday through Tuesday... 
higher amounts of Mexican moisture will slowly creep north into 
parts of far Southeast Arizona late Saturday and Sunday....however still 
remain at Bay across parts of our forecast area...namely Phoenix 
/zone 23/ east to Globe/Miami /zone 24/. 


However by late Monday and Tuesday enough low level moisture may 
spread north into parts of our zone 24 for a slight chance of 
afternoon thunderstorms by Tuesday. Little change in temperatures 
are expected Saturday through Tuesday with near or slightly above 
normal values.

Aviation... 
south-central Arizona...including kphx...kiwa and ksdl... 
southeast California and southwest Arizona including kipl and kblh... 


Continued clear skies and dry conditions. Winds will be occasionally 
gusty during the afternoon hours...but gusts will remain below 20 
knots. Westerly winds will pick up this evening across portions of 
southeast California including kipl where a few gusts in the 20-25 
knot range will be possible. 


Aviation discussion not updated for amended tafs. 


&& 


Fire weather... 
Thursday through Monday... 
very dry southwesterly flow aloft will prevail through early next 
week...with only a slight increase in moisture working into portions 
of southern Arizona by the weekend. Indications are only far 
Southeast Arizona and New Mexico would be affected by this moisture. 
Therefore...dry weather...clear skies...and slightly above normal 
temperatures can be expected through the entire period. Minimum 
afternoon humidity values will fall into the single digits...with 
fair to poor overnight recovery. Some higher wind gusts may be 
possible Thursday and Friday afternoon in the typical 
locations...though still well below any critical thresholds. 
Otherwise...the usual upslope/drainage directional trends will hold 
throughout the period.
