    The previous forecast remains on track for southern California, with
    no changes made. Locally Elevated conditions are possible across
    portions of the southern Great Basin, with 15 mph sustained
    north-northeasterly surface winds overlapping critically low RH and
    receptive fuels. However, given overall cooler temperatures
    expected, along with a weaker surface flow field compared to
    previous days, an Elevated area has been withheld this outlook.

    Although many areas in the West (particularly California, Nevada,
    and Arizona) will remain very dry, surface winds will slacken in
    many areas as Great Basin high pressure weakens and shifts to the
    east of that region.  Additionally, mid/upper flow will slacken as
    an evolving cutoff low moves away toward the southern High Plains. 
    Enough surface flow will remain across coastal ranges of southern
    California to introduce highlights for elevated fire weather in that
    area.  Elsewhere, a cold and unsettled pattern (particularly across
    the southern Plains/Rockies) will keep any fire-weather concerns at
    a minimum.

    Recent high-resolution guidance indicates that areas of 15-25 mph
    surface flow will linger especially in terrain-favored areas of the
    coastal ranges through the forecast period.  The offshore nature of
    the flow will maintain dry low-level conditions (5-15% RH).  Areas
    of dry fuels remain given the antecedent dry conditions through much
    of summer.  These conditions merit an elevated fire-weather
