1254 PM MST Thu Jun 19 2025

.DISCUSSION...
Hot and dry conditions will continue today with winds following
their typical diurnal patterns with some occasional afternoon 
breeziness gusting upwards of 15-25 mph. A few gusts in excess of
30 mph will be possible this evening across western portions of
Imperial County. Winds further increase across the region Friday
and Saturday with afternoon gusts climbing to upwards of 20-30
mph. The strongest gusts will remain focused across the higher 
terrain north and east of Phoenix and across western portions of 
Imperial County, where gusts may exceed 30 mph. Min RHs through 
Friday will be around 5-10% before climbing to around 10-15% on 
Saturday. The dry conditions combined with the gusty winds will 
lead to elevated to locally critical fire weather conditions. 
Extreme heat conditions will continue through Friday across much 
of south-central Arizona with lower desert highs Friday ranging 
between 106-110 degrees.

...Thunderstorms imply gusty winds...
