Day 2 Fire Weather Outlook

0200 PM CDT Wed Aug 27 2025

Valid 281200Z - 291200Z

An IsoDryT area was added for the portions of the Washington
Cascades. High-based showers intermixed with lightning are forecast
to move through the Washington Cascades today into tomorrow morning.
Some clearing is expected late tomorrow morning into the afternoon
that will help initiate thunderstorms over the Washington Cascades
during the afternoon and evening. PWAT values will likely dip below
1" with storm motions of 10-20 knots, helping to reduce rainfall
totals. This combined with very dry fuels supports an IsoDryT area.
Additionally, mixed wet/dry thunderstorms are possible over the
Olympic Peninsula, northeast Washington, and the Idaho Panhandle,
but enough forecast uncertainty exists regarding actual lightning
production and rainfall totals to preclude expanding the IsoDryT
area.

...Synopsis...
Forcing for ascent accompanying a remnant midlevel low will support
isolated thunderstorms across parts of WA during the
afternoon/evening, given sufficient midlevel moisture/buoyancy.
While any storms that form may pose some risk of lightning-induced
ignitions over dry fuels, increasing boundary-layer RH and
potentially low storm coverage may limit the threat compared to Day
1/Wednesday.
