stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

To reduce risk during outdoor work the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency... call 911. A heat advisory means that a period
of hot temperatures is expected. The hot temperatures will create
a situation in which heat illnesses are possible. Drink plenty of

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
1116 am PDT Thursday Jul 31 2014 


Synopsis... 
it will be partly cloudy and hot with isolated thunderstorms 
through the end of the week and into the weekend. No significant 
relief from the hot weather is forecast through the seven-day 
forecast period. However, only a few spots may reach the 100-degree 
mark. Isolated thunderstorms the next several days are not 
expected to be strong or severe but could bring localized heavy 
downpours. 






&& 


Discussion... 
today through Friday...hot temperatures will continue across the 
region with isolated showers and thunderstorms possible across the 
southeast zones today. The ridge axis will shift slightly to the 
east today, but not enough to account for more than a degree or 
two of cooling. Monsoonal moisture will try to push into the NE 
blue mts, Camas Prairie and the central Panhandle mountains today. 
This will work with a weak impulse to allow isolated to scattered 
showers and thunderstorms to develop across the southeast. There 
is a decent amount of cape but bulk shear is rather weak so any 
thunderstorms that develop will tend to be garden variety. There 
is a better push of moisture Friday that will extend into the 
north Cascades as well as the Southeast. Cape will be limited to a 
couple hundred j/kg for the Cascades so there is a slight risk of 
thunderstorms to develop near active fires or recent burn scars. 
Scattered thunderstorms will again develop across the southeast 
zones. Temperatures will continue the above normal trend with 
readings in the 95 to 105 degree range. The highest temperatures 
will be in the Lewis-Clark Valley today where a heat advisory has 
been issued. Fridays temps should be a bit cooler but just by a 
couple of degrees with most valley locations in the 90s. Overnight 
lows will also be well above normal. The warmest readings will be 
in the mid-slope thermal belt at the top of the inversion where 
readings could top out in the 70s. /Kelch 


Friday night through Thursday...the inland northwest will be in 
between and exiting ridge of high pressure and a deep low in the 
Gulf of Alaska through Sunday. A weak upper level front will track 
across the region Saturday night and Sunday. Zonal flow with weak 
ridge will return Monday through the remainder of the forecast 
period. 


Southwest flow is expected Friday night through Saturday night or 
early Sunday. The models are not necessarily in agreement but all 
are showing and influx of Pacific moisture through this portion of 
the forecast. Model pwats increase to 140-160 percent of normal. 
Several weak waves will track through the region, with the upper 
level front between 00z-12z Sunday. Model guidance is showing an 
extended period of both surface based and mid level instability 
through Sunday night. Isolated to scattered showers and 
thunderstorms will be possible each afternoon through Sunday. The 
best chance for nocturnal thunderstorms appears to be Friday night 
and Saturday night. These storms may begin dry Friday night but 
should become mainly wet storms Saturday and Sunday. Temperatures 
will show a bit of a cooling trend with lower heights and some 
cloud cover but will remain above normal. 


Monday through the week the flow becomes westerly with a hint of a 
ridge of high pressure at 500 mb Monday and Tuesday. The region will 
lose the deep Pacific moisture tap, allowing the atmosphere to 
stabilize. A few showers may be possible Monday afternoon across 
the orographically favored Panhandle mountains, otherwise dry 
through Thursday. Temperatures will rebound a few degrees Monday 
and Tuesday under the ridge but cool off close to normal for 
Wednesday and Thursday. /Tobin 




&& 


Aviation... 
18z tafs: VFR conditions expected the next 24 hours. Cumulus will 
develop over the mountains in the afternoon with cirrus moving in 
from the south through the late afternoon and evening hours. 
Isolated thunderstorm development is possible from the blue mtns 
to Lookout Pass this afternoon/evening. We will also have to watch 
for the potential for a few elevated showers coming into the upper 
Columbia Basin overnight into Friday morning, but the threat of it 
passing any taf sites is low. /J. Cote'
