.DISCUSSION...Showers and thunderstorms near the ID/NV border are
weakening and decreasing in coverage. The activity is expected to end
by midnight. Temperatures were lower today due to the passage of a
cold front earlier in the day, and that trend will continue into
Tuesday with highs near normal. The breezy winds will subside
overnight. Dry conditions prevail on Tuesday. No updates.

&&

.AVIATION...Areas of haze from local wildfires. Otherwise VFR. 
Surface winds: W-NW 10-20 kt with gusts to 25 kt until 18/04Z. 
Winds aloft at 10k feet MSL: W-SW 20-35 kt.

.PREV DISCUSSION...
SHORT TERM...Tonight through Wednesday night...Pacific cold 
front has pushed the hot air mass to the east of our CWA but
enough moisture and instability remain along the ID/NV for 
isolated thunderstorms until sunset. Breezy post-frontal 
west/northwest winds will continue elsewhere until sunset.
Then clear and cooler tonight with lighter west winds continuing.
Sunny Tuesday with temperatures near normal. A few afternoon 
cloud buildups in southern Twin Falls County but nothing more. 
Clear with normal temperatures Tuesday night. Next warming
trend will start Wednesday as flow aloft acquires a more 
southerly component from the hot upper ridge to our south. 
That flow will also direct a weak monsoon moisture flow into
Twin Falls County for a slight chance of thunderstorms Wednesday 
afternoon and evening. 

LONG TERM...Thursday through Monday...Continued steady warming
through Saturday as the weak monsoon surge Wednesday night shifts
eastward and the upper ridge builds northward from Nevada in 
response to the next Pacific trough approaching the nw coast. 
Saturday may be as hot as yesterday, but Sunday and Monday look 
slightly cooler as the coastal trough moves inland. Models show
a hint of monsoon moisture over Idaho Sunday and Monday but not 
enough to generate thunderstorms.
