.SYNOPSIS...
Warm and dry conditions as an upper level ridge builds over the
area. Dry flow aloft will continue through the weekend with warm
and dry conditions expected into the first half of next week.
&&
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...Upper level ridge
building offshore continues to lead to a mix of sun and high
level clouds this afternoon. Temperatures warming into the low
60s with dry northerly flow aloft. High clouds will clear out
tonight with temperatures cooling down to the low to mid 30s. A
Frost Advisory will remain in affect for portions of the
Southwest Interior and South Puget Sound for overnight
temperatures near freezing.
Little change of the pattern over the weekend as we will remain
in dry northerly flow across western Washington with warm and
dry conditions. High temperatures over the weekend will warm in
the mid to upper 60s in the interior locations, with areas along
the water in the upper 50s into lower 60s.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Ensemble guidance continues to agree in a weak shortwave passing
over the area on Monday with an increase in cloud cover along
with the potential for some showers over the Cascades. Most of
the interior will remain dry throughout the week and
temperatures will slightly warm to the lower 70s by midweek.
Overnight lows remain in the upper 30s and mid 40s.
