Weather

***Widespread wetting rainfall from two systems expected today-Monday. Some flooding possible.***

The odd weather this summer will continue as the region experiences an early taste of fall conditions today-Monday as a pair of wet systems move SE across the region bringing widespread precipitation and temperatures that are about 20 degrees cooler than normal. The impacts of both will allow for the fire danger indices to fall even further below normal by early next week. Montana PSAs and Yellowstone NP will be the most impacted by both systems...though ID and ND will receive some benefit. Some light snowfall is possible along some of the higher peaks along the Divide near Glacier NP tonight and Saturday. One area that could potentially be missed might be along the ID state line with WA and OR.

The first system is currently arriving and will impact the region through Sunday. NC and NE MT could receive several inches of precipitation. The second system will develop over WA and move into ID and eventually into SC MT Sunday night-Monday. After this second system passes...a ridge of high pressure will begin to move into the region Tuesday from the West bringing a return to warm and dry conditions. A wet cold front will move ESE across the region on Thursday bringing a chance for more wetting precipitation to the western half of the region. After that...confidence in the model data decreases again. One good model brings another wet closed low pressure into the region with more widespread precipitation. Another good model keeps us in a quieter westerly flow pattern that would promote near normal conditions.

Fuels/Fire Potential

The potential for the development and/or growth of large fires is Moderate and is decreasing due to the ongoing precipitation events.

Resources

Resources are adequate.
