WEATHER DISCUSSION: Despite a cooler and rainy Labor Day holiday, Tuesday began on the brighter side. Sunny to mostly sunny skies graced the forecast throughout the region with a first look at warming temperatures. Today, those temperatures heated up into the 70’s with an overnight low into the 50’s. That warming trend continues into the next couple of days as well with daily high temperatures into the upper 70’s and lower 80’s. Drier conditions are also expected for the latter half of the week as well and into this upcoming weekend.

While warm and sunny days are in the forecast, the main concern today and the first half of Wednesday will be hazy conditions. An Air Quality alert is in effect for North, Central, and Eastern MT until 1 pm on Wednesday. Wildfire smoke from Canada continues to pool into the treasure state, creating smoky skies and reduced visibility at times. Closer to Wednesday evening with the assist of a progressive SW flow, much of the smoke and haze is expected to thin and push Eastward out of the state.

The upper-level low responsible for Monday’s rainfall events and cooler temperatures exits Eastward with some lingering isolated showers over the Central portion of the state this evening. Most of the activity tonight however will be over higher elevations in mountainous areas. Following the low is a weak upper-level ridge which will help settle down conditions rebound temperatures back to around average for this time of year. Wednesday looks to be the warmest day of the week this week.
