NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pocatello Idaho 
334 am MDT Thursday Aug 21 2014 


Short term...today through Saturday night. Current water vapor 
imagery shows the upper level trough mainly over our eastern areas 
with a dry slot starting to approach western Idaho. Expect 
isolated convection across our western areas with scattered to 
numerous showers with isolated to scattered thunderstorms across 
our southern and eastern areas today. Friday models continue to be 
consistent in dropping an upper level low over eastern Washington 
bringing widespread precipitation across the area. Precipitable 
water amounts are around one inch across the area. Localized 
flooding will be possible. Models are showing a dry slot across 
the Snake River Plain bringing drier conditions and breezy to 
moderate winds Friday. The upper level low shifts east over 
northern Idaho Saturday morning and then into Montana by Saturday 
night. Expect scattered showers and isolated thunderstorms mainly 
over the central mountains and eastern Highlands on Saturday. 
Expect below normal temperatures today becoming 8 to 12 degrees 
below normal by Saturday. Wyatt 


&& 


Long term...Sunday through next Thursday. Expect isolated 
precipitation chances mainly in the mountains on Sunday in 
west to northwest flow. Models are consistent in bringing another 
upper level low across the area on Monday bringing moderate to 
high precipitation chances particularly across our northern areas. 
Models start trending drier in northwest flow Tuesday and even 
more so on Wednesday. Look for mostly dry conditions in southwest 
flow on Thursday ahead of the next system. Expect well below 
normal temperatures early in the period becoming slight above 
normal by Thursday. Wyatt 


&& 


Aviation...showers and thunderstorms will remain across the area 
through Friday. VFR weather will be the norm except for periods of 
heavier rainfall...which may cause temporary reductions in 
visibility. Winds with storms and outflow boundaries may exceed 
30kts. Keyes/receiver station 


&& 


Fire weather...a low pressure disturbance over southeast Idaho this 
morning with widely scattered to scattered showers of rain with at 
least isolated thunderstorms this morning. The disturbance will be 
moving to the east this afternoon...allowing some drier air to move 
into the central mountains from the west. This will be only a 
temporary break in activity. A new low pressure circulation will be 
moving from British Columbia to northern Oregon by Friday afternoon 
and will support scattered to numerous rain showers across southeast 
Idaho with widely scattered embedded thunderstorms. Friday will be 
another good day for wetting rains. Saturday the low moves right 
over this area. There will be some 10 to 20 miles per hour westerly winds in 
the snake plain but minimum afternoon humidity should be no lower 
than the lower to middle 20s. Another disturbance will drop into 
this area by Monday. The best opportunity for drying conditions is 
Wednesday and Thursday of next week with a brief period of high 
pressure that gives way to more westerlies by weeks end. Receiver station
