<div style="padding-left: 36pt; ">The upper low that brought clouds and light rain to the region Sunday moves northeast and is over Montana by Monday. Expect a mixture of sunshine and clouds. There will be enough surface heating to push mixing heights to
5000 feet or better for good smoke dispersal conditions most areas. </div>

<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">There will be a drier and warmer air mass over the region on Tuesday. Again, daytime heating pushes mixing heights to 5000 feet or above for good smoke dispersal conditions. On Wednesday a broad upper trough approaches the
Pacific Northwest turning upper flow southwesterly. Expect dry weather and good smoke dispersal conditions. On Thursday flow aloft is west-northwesterly. Very minor impulses moving through the flow should not have much effect on the region. </div>
