.DISCUSSION...



WEATHER PATTERN OVERVIEW: 



A final warm day is expected over NE Montana today though with

increased uncertainty with the presence of a stationary front in

the northeast, increased cloudiness, and isolated rain showers.

In any event, any precipitation amounts will likely be on the

lighter side. That ridge breaks down with additional showers

riding along the boundary over the weekend as temperatures tick

lower.



Ensembles show upper ridging returning across the western U.S. for

early next week with dry weather and warming temperatures again.

That said, embedded shortwaves and ridge flattening toward the

middle of the week will keep the warm up short lived and rain

shower chances remaining active across the region. 



FORECAST CONFIDENCE & DEVIATIONS:



The main deviation this cycle was to ramp up wind speeds for the

short term forecast period. Want to highlight somewhat reduced

confidence on highs today given increased cloudiness expected as

well. Regardless, NBM captured the overall fluctuations and light

precipitation chances well for the balance of the upcoming week.
