(MISSOULA)- A massive high pressure system that has put the Northwest into an extended drought may be finally breaking down.
At least the forecast is finally showing a chance for some showers in the forecast for the first time in weeks.
The high pressure system has been locked over the Western United States since early August. The National Weather Service says at times the pressure has reached as far north as the Yukon, blocking any Pacific weather systems from bringing moisture to the Northwest.
Missoula has only seen a trace of measurable rain in September and is within days of breaking the all-time record for a lack of precipitation this time of the year.
However, a low pressure system moving across Oregon and into Idaho might indicate a change is about to happen. There’s not much moisture with the system, and NWS forecasters say it will probably travel south of the region, but it could generate a few isolated showers in Eastern Idaho and Southwest Montana.
On Tuesday, a fast-moving disturbance is expected to move across the Northern Rockies that could generate some isolated afternoon showers. That’s expected to bring more moist, cool conditions that should suppress fire activity in the region and reduce some of the smoke build up.
