Area Forecast Discussion
National Weather Service Spokane WA
1101 AM PDT TUE JUL 22 2014

.SYNOPSIS...
A strong storm system will approach the region today and pass
through on Wednesday. The threat for thunderstorms will increase
across the southeast today then spread region-wide tonight and on
Wednesday. Some storms could be strong and wet bringing the
potential for strong winds, hail, and heavy rainfall. Temperatures
will rebound by the weekend and be accompanied by dry conditions.

.DISCUSSION...
Main changes to forecast through this afternoon was to increase
precip chances and QPF in the ID Panhandle and in the Cascades. A
batch of showers is moving through the region this morning. Much
of the steadier rainfall has occurred over the ID Panhandle into
extreme portions of eastern WA. We are also seeing some showers
developing across the Cascade Mtns. These showers have generally
been light across these areas with less than 0.05 inches so far.
Showers are expected to continue in the Cascade Mtns and across
the northern mtns of WA and ID through at least the early afternoon
hours. We will then see a little bit of a break around mid
afternoon with mainly some isolated to scattered shower activity
possible.

A slight chance of thunderstorms is possible during the afternoon
for the eastern half of the forecast area; however, the best
chances for thunderstorms will be this evening into tonight as a
wave currently MOVING into California this morning moves up
through the Inland Northwest. Convection is expected to blossom
over OR this afternoon and then begin to track into WA this
evening. Best chances for thunderstorms will be across southeast
WA into the Central Idaho Panhandle. Some of these thunderstorms
may become strong this EVENING with gusty outflow winds and small
hail possible. /SVH

.AVIATION...
18Z TAFS: A low pressure system circulating off of southeast BC
will continue to push moisture across the Inland Northwest. Much
of the showers through the early afternoon will be north of the
TAF sites. However, the atmosphere will destabilize late this
afternoon with a redevelopment of showers and thunderstorms
into tonight. The strongest thunderstorms are expected to develop
over northeast OR and track into southeast WA and into the central
portions of the ID panhandle. Gusty outflow winds and small hail
will be possible with these thunderstorms through the evening.
