1035 PM PDT Tue May 7 2024

.SYNOPSIS...
A warming and drying trend is forecast through the weekend.
Temperatures on Friday through the weekend will warm to the
highest values of the season so far, with high temperatures
reaching the 80s for much of the region.

&&

.DISCUSSION...

Tonight and Wednesday: The Low from the past few days is east of
the Inland Northwest. It is still bringing some isolated shower
activity to extreme Eastern Washington and the Idaho Panhandle
through the evening. As the low slides farther east, it will push
a weak band of showers north to south over these areas. Shower
activity will diminish over these areas through Wednesday
morning. The morning lows will be coldest for the next several
days as a warming, dry trend will begin to build into the region.
The lows will be in the 30s to low 40s. The highs will be in
the upper 50s to low 70s.

Thursday through Sunday: The period will be dominated by a ridge
off the coast. The ensembles are in good agreement of dry,
warming trend through the weekend. Each day will be a few degrees
warmer than the previous before peaking over the weekend.
Temperatures are expected to average 10-15 warmer than normal by
the weekend. The region can expect widespread 80 temperatures by
the weekend. The Central Basin could see some locations reach into
the low 90s. Overnight lows will be in the upper 40s and 50s.

Monday and Tuesday: The ridge pattern begins to flatten late
Sunday breaking the warming trend from the weekend. The ensembles
are not showing much in the way of precip. There are a couple of
weak shortwaves that slide through Southern BC. These could
produce light shower activity along the border. Temperatures will
trend to season normals for this time of year. Highs will be in
the upper 60s to 70s. Lows will be in the 40s to low 50s. /JDC
