NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Pocatello Idaho 
334 am MST Sat Feb 6 2016 

Short through Monday night. Current water vapor 
imagery shows a low pressure trough and associated cold front 
starting to move over northern Idaho. Models show this system 
impacting mainly our northern areas this morning into the 
afternoon. This system is mainly dry. However...expect an inch of 
snow or less over the central mountains and Caribou Highlands 
with the upper snake Highlands receiving 2 to 4 inches of snow 
mainly along the Wyoming border. Expect breezy winds this morning 
into the afternoon with gusts of 25 to 35 miles per hour. A strong high 
pressure ridge will start building in Sunday into Monday. Expect 
dry conditions Sunday through the remainder of the week. This high 
pressure ridging will also bring valley inversions which will 
deteriorate air quality. By Monday expect day time temperatures in 
the 40s for mountain locations such as Stanley. Wyatt 

Long term...Tuesday through Saturday night. Strong upper ridge over 
the west will persist through Thursday. Inversion conditions will 
result in nighttime low clouds and patchy fog in the valleys...while 
higher elevations will see much warmer temperatures. The European model (ecmwf) has backed 
off on precipitation for Friday and Friday night and come more in line with the 
GFS in bringing a split flow upper trough into the west. Most of the 
energy with this system will be well south of the area...with only 
slight chances for snow in the mountains Sat and Sat night. Hedges 


Aviation...low ceilings over the upper Snake River Plain expected to 
lift later this morning...with more improvement this afternoon. Low ceilings 
likely to return tonight. Patchy light fog in the lower snake plain 
should be gone by sunrise as south winds pick up. The rest of the 
area should remain VFR. Hedges
