.SYNOPSIS...
Independence Day will see increasing clouds and some areas will
have a chance for showers. Thunderstorm potential also exists
on for far southeastern Washington, the central and southern
Idaho Panhandle, and the North Cascades on Saturday. Hot
temperatures arrive on Monday and may persist through the
remainder of next week.

.DISCUSSION...
Tonight through Saturday night: Moisture continues to push
north tonight, but with how dry the atmosphere is along with
seeing what has occurred in northern Oregon, PoPs have been
reduced throughout Friday evening. Rain that does fall will
remain light, with much of it being virga. This could lead to a
slight increase in winds this afternoon and evening, with most
areas not exceeding 15 to 20 mph. Cloud cover will continue
through the overnight hours before we begin to see breaks on
Saturday. As this shortwave moves through on Saturday, it will
interact with lingering moisture and modest instability to
trigger scattered showers and isolated thunderstorms in the
afternoon over the higher terrain in northeast WA and the ID
Panhandle. Any storms that do form could be capable of brief
heavy rainfall, gusty winds and lightning. While the overall
coverage is expected to remain limited, conditions will be
monitored closely due to the holiday weekend.

Sunday through Wednesday: Following the exit of Saturday`s system, a
strong ridge of high pressure is expected to build into the region.
This will mark the beginning of another warming trend, with dry,
unstable conditions returning. Each day will increase in
temperatures, with Tuesday and Wednesday being the warmest days.
Ensembles are indicating that yet again we could see warmer
temperatures than the last heat wave. Temperatures in the high 90s
to 105 are expected as of this forecast, with the hottest
temperatures being down in the LC Valley and Columbia Basin. This
could bring the potential for widespread impacts from heat stress to
increased fire danger. Winds will begin to increase Wednesday
afternoon as another system begins to push in offshore. Overnight
temperatures will be warm was well, with most areas remaining in the
60s to around 70. Beyond Wednesday, we begin to see model spread
on whether temperatures will remain hot, or if they will start
to cool down slightly. Keep an eye on the forecast as we get
closer. /KK
