- Weather will trend toward warmer and drier through the middle of the week as upper ridging rebounds.

- As the ridge slides east hot temperatures will peak late week as thunderstorm chances begin to increase.

DISCUSSION

WEATHER PATTERN OVERVIEW:

Breezy northwest winds continue with a Lake Wind Advisory for Fort Peck Lake remaining in effect through 9 PM.

Clear skies will continue into tonight before upper ridging begins to rebound across the region into the middle of the week. This will lead to warmer and drier weather conditions during that time.

The ridge axis will slide east into the Plains late into the week with an increase in thunderstorms and a return to hot temperatures. Some of the storms may produce locally heavy rainfall, but they will be isolated to scattered.

FORECAST CONFIDENCE & DEVIATIONS:

NBM was blended with NBM90 for short term winds as wind speeds were arriving on the higher side of the guidance envelope. Otherwise given warm and dry weather controlled by large scale ridging for the next several days, NBM captured the expected forecast well with little to no deviations.
