An upper-level ridge will build over the Southwest US late this week
into this weekend. Expansive thunderstorm activity is expected
across the Southwest Friday and Saturday due to remnant moisture
from the westward-moving Tropical Storm Alberto off the TX/Mexico
coast this afternoon. Through time, thunderstorm activity is
expected to become more isolated into early next week. No IsoDryT
probabilities have been added, as the robust nature of the moisture
push should result in mostly wet thunderstorms.

The threat for dry and windy conditions is expected to increase
early next week, as an upper trough traverses the Pacific Northwest.
A cold front is expected to cross the Cascades with dry and breezy
westerly flow in its wake. A mix of dry/cured and green fuels are
present on the eastern Cascade foothills and the Columbia Basin.
These marginally dry fuels are the primary precluding factor to
greater Critical probabilities. However, some large-fire threat is
expected, especially if a fire can begin/establish in the drier
fuels. In addition to the Columbia Basin, some dry and breezy
conditions are possible in the Snake River Plain as increasing
mid-level flow overspreads the dry and well-mixed airmass.

Beyond this weekend, the ridge is expected to maintain across the
Southwest with building heat and drying fuels. The pattern will
remain favorable for shortwave trough passages through the
Northwest, which will be monitored for increased fire weather
potential.
