Area Forecast Discussion
National Weather Service Spokane WA
952 AM PDT Thu Jul 28 2016

.SYNOPSIS...
Hot and mostly dry weather is expected Thursday and Friday. A
cold front arrives this weekend, bringing breezy conditions and
cooler weather for the start of next week. A few showers or
thunderstorms will be possible over the northern counties early
next week.

&&

.DISCUSSION...
Morning update: Main forecast challenge for this afternoon and
evening will be whether convection can fire in the north Cascades.
We are dealing with another moist and unstable air mass
environment residing under a CIN layer. If parcels can break
through the CIN layer, isolated storms capable of heavy rainfall
are a strong possibility. If the CIN layer holds similar to
Tuesday, we are looking at shallow cumulus. There is a very weak
midlevel wave evident on morning water vapor west of 130W which
could prove to be the trigger during the early evening hours but
overall confidence is very low. /sb

.AVIATION...
18Z TAFS: A westerly flow and weak disturbance may bring isold
-shra/-tsra north of Lake Chelan/Methow Valley and near the
northern mountains. Some afternoon CU is expected too, largely
near the mountains. Otherwise dry/VFR conditions prevail. /sb
