...WARMING THROUGH THURSDAY...
...SLIGHT CHANCE OF SHOWERS/STORMS TUESDAY...
...COLD FRONT FRIDAY/SATURDAY...

.DISCUSSION...

* Southwest Idaho BLM (ID Zones 400, 420, 423, 424, 426)...Temperatures
  general warm alongside drying conditions through Thursday,
  peaking on Thursday at 10-15 degrees above normal for this time
  of year. The warming is briefly interrupted on Tuesday as a
  quick moving system brings a 20% chance of precipitation and
  increasing cloud cover. Rain showers and thunderstorms will be
  focused on the higher terrain along and north of the Nevada
  border. Later in the week, a strong Pacific system will carry a
  cold front through the area, dropping temperatures about 15-20
  degrees from Thursday. Precipitation chances with the front are
  lower, at 10-20%, and confidence is low due to timing differences
  amongst guidance.

* Southwest Idaho Forest (ID Zones 401, 402, 403,
  421)...Temperatures general warm alongside drying conditions
  through Thursday, peaking on Thursday at 10-15 degrees above
  normal for this time of year. The warming is briefly interrupted
  on Tuesday as a quick moving system brings a 20% chance of
  precipitation and increasing cloud cover. Rain showers and
  thunderstorms will be focused on higher terrain in the southern
  Central Idaho mountains. Later in the week, a strong Pacific
  system will carry a cold front through the area, dropping
  temperatures about 15-20 degrees from Thursday. Precipitation
  chances range from 20-30% near Payette NF to 10-20% in Boise NF,
  increasing to the north. The exact chance of precipitation is
  still low confidence due to timing difference amongst guidance.

* Southeast Oregon (OR Zones 670-675)...Temperatures general warm
  alongside drying conditions through Thursday, peaking on
  Thursday at 10-15 degrees above normal for this time of year.
  The warming is briefly interrupted on Tuesday as a quick moving
  system increases cloud cover across the area. Rain showers and
  thunderstorms are possible in Baker County Tuesday evening.
  Later in the week, a strong Pacific system will carry a cold
  front through the area, dropping temperatures about 15-20
  degrees from Thursday. Precipitation chances during the frontal
  passage are highest in northeastern Oregon at 20-30%, however
  confidence is low due to timing differences amongst guidance.
