KEY MESSAGES

- Daily isolated to scattered afternoon showers and thunderstorms expected today through Saturday.

- Extreme heat is expected Friday through Sunday with high temperatures 95 to 110 degrees. Take the necessary precautions to stay safe from the heat.

- Hot, dry and breezy conditions are expected Friday. Take care not to cause a spark.

UPDATE

Weak shortwave tracking along the MT/WY border continues to produce scattered showers and a few embedded weak thunderstorms this morning, mainly to the S/SE of Billings but there is some activity to the west including a thunderstorm near Bozeman Pass. Over time we will see shower activity slowly diminish as the wave exits to the east, but pwats remain quite elevated today and if surface temps reach the lower 90s as expected, some surface based instability should be released. Thus will keep a mention of isolated TS this afternoon and early evening across most of the area. Building ridge and mixed west winds turn us much hotter and drier Friday. JKL

AVIATION

Isolated to scattered showers will linger through the morning along or near the MT/WY border. Isolated showers/thunderstorms will develop across the area this afternoon, particularly over the mountains and in the southeast corner of Montana. Stronger storm cells will be spotty (<15%), but may produce brief heavy rain and erratic wind gusts. Wildfire smoke from the Pacific NW may produce slant range visibility reductions at times, but surface visibility reductions are not expected at this time. BT
