.DISCUSSION...
Tonight and Tuesday: A ridge pattern over the region will bring a
mild, dry period. There is no threat to precip. The overnight lows
will be in the upper 40s to 50s. Tuesday highs will be a few degrees
higher than Mondays reaching into the 80s and low 90s.

Wednesday and Thursday: An incoming low will bring a big shift to
the pattern to the region. Ensembles are good agreement on the
timing. They do differ on the strength and moisture associated with
with the low. The GFS is bringing a quick moving plume of moisture
starting late Wednesday morning. The EC is not carrying the plume.
The instability parameters are also stronger with the GFS. The
forecast leans more to GFS. It has introduced thunder potential for
most of eastern Washington particularly along the the Cascades on
Wednesday morning. The probability of thunder is at least 12%. By
the evening, the threat of showers and thunder over the Basin has
diminished. It still exists over the Cascades, northern
mountains, and North Idaho Panhandle. Showers and potential
thunder remain in these areas through Thursday as the Low
continues to slide through region. The main concern with the
storms will be lightning. High temperatures will take a decent dip
between the two days. Highs will be in the 80s and low 90s for
Wednesday and drop into the 70s for Thursday. Overnight lows will
continue to be in the 40s and low 50s.

Friday and the weekend: A ridge is expected to fill in behind the
low and bring a return of warm, dry weather through Saturday. Highs
will climb back up to the 80s and low 90s. The next system on Sunday
will not be as strong as the midweek system. Any shower activity
will generally be in the northern mountains. Highs will drop
slightly to upper 70s and 80s. /JDC
