NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
1022 am PDT Friday Sep 19 2014 


Synopsis... 
a strong high pressure ridge will return today and promote warm 
and dry weather through Tuesday. High temperatures Sunday and 
Monday should be ten degrees above normal. The breakdown of this 
ridge...and a return to cooler conditions...will begin Wednesday. 
However...precipitation and much cooler weather is not expected 
until Wednesday night or Thursday for most communities since the 
front will likely move very slowly east. 




&& 


Discussion... 
rest of today...there is no compelling reason to make any updates 
to the current forecast inherited from the previous shift. Overall 
an upper level ridge will be building today. Cloud cover and light 
showers apparent on radar and satellite over the west side this 
morning is expected to weaken as this already weak system scoots 
along the Canadian border today....with a ghost of a chance ofa 
shower on the high terrain north of the Columbia Basin. Otherwise 
dry and increasingly sunny conditions today with lighter winds 
than yesterday...and cooler temperatures but still around normal 
for this time of year. /Fugazzi 


&& 


Aviation... 
18z tafs: a building upper level ridge will promote dry and stable 
conditions over the region. VFR conditions are expected at all 
taf sites for the next 24 hours. /Mjf
