NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
213 PM MDT sun Aug 30 2015 


Discussion...most of the precipitation associated with the trough 
crossing northern Idaho tonight should remain north of this area. 
Kept a slight chance of a shower in for a few hours this evening in 
Custer County. Winds in the upper snake plain are expected to drop 
off near sunset this evening. Both Monday and Tuesday are expected 
to be dry under flat westerly flow pattern. Models have slowed the 
development of the low pressure trough that develops middle week. There 
will still be a dry cold front coming in Wednesday for a breezy day. 
Another disturbance was expected on Friday but appears to be delayed 
enough to keep southeastern Idaho in warm southerly air until 
Saturday. High temperatures Friday were the single biggest change to 
the current forecast. Receiver station

Aviation...southwest flow continues today...but more stable 
conditions expected. Upper trough over central Washington may 
produce showers/thunderstorms over central mountains but models keep 
active weather north of ksun throughout the day. Thus expecting to 
keep VFR conditions going through the period. Winds expected to be 
gusty across the snake plain this afternoon/evening with strongest 
winds at kida with gusts up to 30 kts. Hinsberger 


&& 


Fire weather...upper trough is making its way across central Washington/or 
with southwest flow ahead of it. Showers/isolated thunderstorms 
development is possible over the central mountains and into Lemhi 
County. A west/southwesterly flow will increase through the 
afternoon as the trough approaches with some ridge-top wind gusts 
near 35 miles per hour. Humidity is about 10 percent higher today on account of 
the cooler airmass...but we may see downslope winds create low 
humidity around the middle to upper teens in the valleys of fire zone 
476 this afternoon. Not anticipating a red flag at this time...but 
will closely monitor relative humidity trends through the afternoon. Monday will 
generally be less breezy with no precipitation expected. Winds may pick up 
again Tuesday afternoon across the central mountains along a weak 
dry cold front...but the front will intensify on Wednesday as upper 
level support provides reinforcement. Look for possible thunderstorm 
development Wednesday afternoon/evening along with breezy 
conditions. Hinsberger

Pih watches/warnings/advisories...none.
