.SHORT TERM...for northeast Montana...tonight through Sun...

With the exception of one weak wave of low pressure Saturday
afternoon through Saturday night, the short term forecast period 
looks to be rather un-eventful.

Sheridan County in our NE CWA corner has left-over standing water
in the Mid Muddy Creek floodplain and may lead to some patchy 
overnight and morning fog, but it is not expected to be as thick 
or as widespread as it was this morning. Next shift should keep an
eye on this, just in case. 

This next weather disturbance will ride along a Pacific NW 
trough, but will not have near enough moisture to make enough of 
an impact for most of our CWA. Models are lining up a band of rain
showers with this system moving through our SE zones. Best 
chances for accumulating rain showers would be near and south of 
the Big Sheep Mountains. 

Expect warm days and cool to cold nights.

.LONG TERM...Sun night through Fri...

AFTERNOON UPDATE: 
Updates for the afternoon were minimal. Forecast builder was run
to cycle in the latest data; However, very few changes were made
on top of this. PoP grids on Tuesday/Tuesday night and
Thursday/Thursday night were increased beyond builder's output  
to better match up with neighbors. No other significant changes
were observed.

PREVIOUS LONG TERM DISCUSSION:
Progressive pattern for next week with a series of shortwave trofs
moving through the regions. Strongest energy with these systems
expected to push through the desert southwest but with enough 
connection to the north portion of the trof to bring some
potential for showers into eastern Montana.

Monday is expected to be dry and warm with trof digging into the
Great Basin. This system moves across the Rockies on Tuesday for
slight cooling of temperatures and some showers possible. 

Pattern repeats with dry weather on Wednesday followed by trof and
showers on Thursday. Models intensify the southern portion of the
trof as it closes off over the SW states. This will keep the
cooler and potentially wet weather over eastern Montana into
Friday.

.AVIATION...

VFR conditions will prevail for all TAF sites throughout the TAF 
cycle. Some overnight fog may develop again tonight but it is 
expected to be east of the N Dakota / Montana state line. 

Winds from the south 10-15 kts will turn more from the southeast 
later tonight, diminishing only slightly
