NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
228 am MDT Wednesday Jul 29 2015 


Short term...a dry high pressure ridge begins to take hold today 
and will persist through Friday. Afternoon high temperatures 
expected to be about 10 degrees warmer this afternoon and trend 
upwards another 4 to 5 degrees on Thursday. Along with 
this...morning lows will be warmer as well and will be above the 
local frost zone except for very patchy ares in the mountains. 
Otherwise...generally clear skies and light winds. Receiver station 


Long term...beginning Saturday...high a ridge of high pressure 
begins to center itself near The Four Corners area. This is 
favorable for monsoon moisture to move north through California 
Saturday and eventually into southeast Idaho by Sunday. This puts 
US back into thunderstorms developing each afternoon and evening. 
Somewhere around next Wednesday we will be looking for a 
disturbance to come in off the Pacific and change this pattern. Receiver station 


&& 


Aviation...widespread VFR conditions under high pressure ridge 
today and Thursday. Receiver station 


&& 


Fire weather...southeast Idaho will be under a dry high pressure 
ridge today through Friday. Afternoon highs will trend up today 
about 8 to 10 degrees while afternoon humidity around 
Salmon...Challis...Arco and Shoshone lowers to near 10 percent. 
Mainly slope winds will prevail everywhere. Focus continues to be on 
high pressure near The Four Corners area beginning about Saturday. 
Monsoon moisture begins to take a wide track through California and 
by Sunday advances into Idaho. We will be under the influence of 
this monsoon moisture with afternoon and evening thunderstorms 
until a low pressure trough off the Pacific moves inland about the 
middle of next week. Receiver station 


&& 


Pih watches/warnings/advisories...none.
