NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
154 PM MDT Wednesday Apr 1 2015 


Short term...tonight through Saturday. 


Noticeably colder weather over the region today as an upper level 
trough digs into the region. Have seen a few convective showers 
pop up across northeast Idaho this afternoon. Much of this will 
diminish this evening along with the gusty winds. Expect cooler 
weather on Friday as the base of the trough swings through. Winds 
should be lighter as well. Will probably see showers once again 
and likely a little further south to near American Falls and 
Pocatello in addition to where they were today. Woudnt be shocked 
if a rumble of thunder occurs given negative lifted indices across the area 
Thursday afternoon. Not looking for much snow accumulation...generally 
half an inch or less. Upper level ridge returns for Friday and 
Saturday. This will produce dry weather across the region. Temperatures 
will be slightly warmer on Friday and back into the low 60s for 
many places on Saturday. 


Valle 


Long term...Saturday night through Wednesday. 
Both GFS and European models show cold front moving through Sunday 
or Sunday night with the GFS fastest with movement. Expect Sunday 
and Monday to be best chances for precipitation as upper level trough 
slides east. Snow levels should drop to valley floors Sunday night 
but expect brunt of precipitation to be in mountains. GFS spreads 
upper level ridge east Tuesday with an upper trough quickly 
approaching Wednesday. European is weaker with ridge Tuesday with a 
broad upper trough over Idaho Tuesday into Wednesday. Neither is very 
wet with the middle week trough at all so kept the low chance probability of precipitation in the 
mountains going Wednesday. Temperatures in the long term should be 
near normal to below normal most likely on Monday which looks like 
the coldest day. May warm to slightly above normal by middle week.

&& 


Aviation...should see VFR conditions through Thursday but 
occasional snow showers and MVFR conditions could possibly Spring up 
this afternoon and early evening mainly near Ida and sun. May need 
to add a tempo group to allow for the convective snow showers. 
Similar conditions expected Thursday. 12 to 24 knot winds at 
byi..pih and Ida will die down at sunset and expect lighter winds on 
Thursday.
