Area forecast discussion 
National Weather Service Tucson Arizona 
840 am MST sun Apr 30 2017 

Synopsis...high pressure will bring clear skies, dry conditions 
and a strong warming trend through the upcoming week. 


Discussion...clear skies this morning under northwesterly flow 
aloft. We did see a few spots across the lower valleys of Santa Cruz 
and Cochise County dip near to slightly below the freezing point 
this morning. Hopefully, this will be the last freeze until the fall 
at lower elevations. A warming trend to well above normal 
temperatures by the end of the week will begin today. Highs this 
afternoon should top out a few degrees below normal for the end of 
April. Abundant sunshine and dry conditions will be the rule this 
week, along with less wind/fire weather concerns. The big story will 
be the potential for ktus to record the first 100 degree day of 2017 
by week's end. No updates are needed this morning. 


Aviation...valid through 01/18z. 
Sky clear conditions through the period. Surface wind less than 10 kts this 
morning becoming westerly/northwesterly 10-15 kts with gusts up to 25 kts. 
Stronger winds possible near ksad. Surface wind diminishing to less than 
10 kts this evening into Monday morning. Aviation discussion not 
updated for taf amendments. 


Fire weather...dry conditions will prevail into next Saturday. 
Expect markedly less wind as well through Wednesday, although 
afternoon gusts will occur due to daytime heating. A somewhat tight 
surface pressure gradient Thursday into Friday should produce 
elevated east to southeast winds. Daytime minimum relative humidity 
will be in the single digits at lower elevations and the teens in 
the mountains.
