Area Forecast Discussion
National Weather Service Spokane WA
1042 AM PDT Wed Jul 17 2019

.SYNOPSIS...
The next system is moving into the region bringing an increase
in clouds. Widespread breezy to windy conditions are expected
Wednesday into Thursday. Spotty showers will continue in the
northern mountains through the work week. Expect a cold morning
Friday before hot and dry weather returns by Sunday into early
next week.

.DISCUSSION...
Rest of today...A swift westerly flow carrying a fetch of deep
Pacific moisture will lead to thick mid and high clouds over the
region today and into this evening. Radar suggests some of this
overcast is thick enough to produce at least areas of virga and
probably a few sprinkles from time to time in the basin along with
a chance of actual measurable light rain showers over the higher
terrain surrounding the basin. It will also be quite breezy
across the region today with momentum transfer of the higher winds
aloft down to the surface mainly over the rising terrain of the
eastern basin and the ridgetops around the area. Forecast updates
to the Today period include widening out a small chance of
showers or sprinkles and lowering expected high temperatures by a
few degrees owing to little sunshine expected this afternoon.

.AVIATION...
18Z TAFS: Mid and high level moisture preceding another incoming
frontal system will promote thick mid level and high cloud
ceilings across the region today but ceilings will likely remain
VFR at all TAF sites. A few light showers falling out of the
cloud cover are possible mainly north of interstate 90 today but
no convective development is expected near any TAF sites with a
small chance of heavier convective showers mainly along the
Canadian border region this afternoon. Breezy conditions will
impact all TAF sites today and this evening. Conditions will
remain locally breezy tonight but clouds will thin out as the
polar jet axis sags into the southern WA and northern Oregon
overnight. /MJF
