...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL INTO SOUTHERN
OREGON...

...Synopsis...
Upper ridging will dominate the Interior West as an upper low
meanders off of the West Coast today. Monsoonal moisture will pivot
northwestward around the periphery of the upper ridge across the
Desert Southwest into the Pacific Northwest, where scattered
thunderstorms are expected to develop by afternoon. Across far
southern Washington into central Oregon and extreme northern
California/northwestern Nevada, many of the thunderstorms are
expected to be high-based. Forecast soundings in this area by
afternoon peak heating suggest that a very dry boundary layer will
extend up to 500 mb amid precipitable water values around 0.75
inches. As such, a mix of wet and dry thunderstorms is expected to
overspread modestly to highly receptive fuels, warranting isolated
dry thunderstorm highlights. Scattered dry thunderstorm highlights
were also maintained across central/southern Oregon, where the
latest high-resolution guidance consensus continues to depict the
greatest concentration of thunderstorms. Lastly, high-resolution
ensemble guidance shows relatively high potential for erratic and
gusty winds (perhaps 30-45 kts) acco*panying the stronger
thunderstorms across the southern Cascades, which may exacerbate any
new or pre-existing fire starts.
