    South-Central Arizona including KPHX, KIWA, and KSDL:
    
    A cold front over southwest AZ and extending northeastward across
    north-central AZ (and beyond) as of 12Z will continue moving
    eastward as the day progresses. Anticipate the front to track
    across metro Phoenix in the 14Z through 18Z time frame bringing a
    wind shift from southeast to southwest (reaching PHX between 15Z-
    16Z). Gusts look to be modest with the front (10-20 kts). It will
    be accompanied by stratocumulus with bases of FL060-080 along with
    scattered showers for a few hours. Can't rule out PHX ceiling
    touching BKN050 in a shower but confidence too low to show that in
    the TAF. Anticipate some temporary thinning of clouds in the
    afternoon with more frequent gusts of 20-25 kts. Cloud bases will
    lower again after 00Z this evening with isolated showers but
    anticipate they will remain above BKN050. Expect more numerous
    showers and lower cigs over higher terrain north and east of metro
    Phoenix (higher mountain tops obscured). Anticipate clearing from
    west to east beginning after 06Z.
    
    
    Southeast California/Southwest Arizona including KIPL and KBLH:
    
    Very strong west winds over Imperial County will decrease markedly
    by 14Z this morning. Elsewhere, winds haven't been nearly as
    strong (gusting 20-25 kts). Anticipate strengthening of westerly
    winds after 18Z with gusts of 25-30 kts common. Local blowing dust
    is possible but too isolated to depict in TAFs. Most areas will
    have cloud bases AOA FL100 except for La Paz County which will
    have some local ceilings of FL070-090 with isolated showers until
    about 19Z.
