Forget the April showers. But watch out for the April high water.

The rainy weather that dominated the last week will dry out this weekend as a new high-pressure ridge settles over much of the western United States. In Montana, that means increased spring runoff in rivers and streams, as well as a chance of breaking some high-temperature records on Monday.

“It looks like it could stay fairly warm through Tuesday and into Wednesday,” said National Weather Service meteorologist Trent Smith in Missoula. “We’ll be up into the 70s and maybe the 80s through mid-next week.”

Hydrology models don’t forecast any of the state’s major rivers to reach flood stage, although several may get pretty close. In particular, the Yaak River near Troy and the Fisher River near Libby could see high flows over the weekend.

The wild card comes up later next week, when a surge of moisture from the Southwest could bring rain and perhaps thunderstorms. The system is expected to settle in Thursday night or Friday, but forecasts are uncertain how much rain might result.

Meanwhile, Butte has a chance of breaking a high-temperature daily record that’s stood since 1910. On April 23 of that year, the high was 75. This Monday, the forecast calls for 80 degrees.
