.SYNOPSIS...
Temperatures will cool into the 80s for Thursday with a chance of
showers on Independence Day. Thunderstorm potential also exists
on Independence day for far southeastern Washington and the
central and southern Idaho Panhandle. Hot temperatures arrive
on Tuesday of next week and may persist through the week.

.DISCUSSION...

Today through tonight: As the ridge moves out of the area,
temperatures drop further today, with highs 6-7 degrees lower than
yesterday. Some breezy winds remain, but will not be as strong as
yesterday`s winds. Dry conditions and clear skies prevail.

Friday through Saturday: As Independence Day nears, models are
hinting at a more active weather pattern than initially thought. A
low pressure system passing to our south will usher a shortwave in,
increasing the chances for precipitation Friday afternoon and
evening. Precipitation chances will be highest in far southeastern
Washington and the Idaho Panhandle, but cannot be ruled out for
Spokane and Coeur d`Alene, as well as in the northern Cascades.
Lift generated by the incoming shortwave will result in a small
chance for thunderstorms, particularly in far southeastern
Washington and into the central and southern Idaho Panhandle.
Highest chances for thunder are 10- 15 percent, but a very close
eye will be kept on both thunderstorm and rainfall potential
considering the holiday. Bigger potential for thunderstorms
arrives Saturday, as the shortwave is moving out of the forecast
area. On Saturday afternoon and evening, thunderstorm chances
move northward and into northeastern Washington and the Northern
Idaho Panhandle. NBM probabilities show a 15-20 percent chance
of thunder for the far northern Idaho Panhandle.

Sunday through Wednesday: Models are now in good agreement of a
warmup beginning Sunday as a ridge moves through. This ridge will
strengthen at the beginning of next week and bring a return to
temperatures in the high 90s. Right now extended models show
Wednesday as the hottest day, with temperatures in the high 90s with
places like Lewiston, Wenatchee, Colville, Moses Lake, and deeper
Basin areas seeing triple digits. Keep an eye out as heat headlines
may be needed. /AS
