Wednesday is shaping up to be a rainy day in Billings, but Thursday should give residents a break from wet weather before thunderstorms move into the area Friday.
The National Weather Service has issued a Hazardous Weather Outlook over the weekend, warning that an atmospheric disturbance out of the Pacific Northwest will slide through Idaho before reaching Montana Friday.
The storms could increase chances for thunderstorm development Friday and Saturday, the warning said.
Rain, while not severe, is expected Wednesday. The NWS forecast calls for a 50 percent chance of showers and thunderstorms and mostly cloudy skies. Highs will reach 66 and wind from the north will blow 9 to 15 mph.
Skies will break Wednesday night as a weather system known as an upper trough moves in. The trough will lift clouds and showers out of the area, replacing the moisture-laden air with drier air. Low temperatures are expected to reach down to 47.
Drier conditions are expected to stick around Thursday as skies become mostly sunny and highs reach 76. Nine to 11 mph winds out of the east are likely.
A 20 percent chance of showers and thunderstorms is expected Thursday night as lows approach 54. East winds 8 to 17 mph are expected.
