West-wide Heat Wave

Posted at 5:18 PM, Jul 08, 2024

Soaring temperatures have spread across the West over the last several days and now some of that heat is moving into Montana. Get ready for serious heat that will last for days if not weeks across Big Sky Country. After a pleasant and even cool Independence Day Holiday, dangerous heat will beat down on Montana for an extended period. If you thought Monday was hot, Tuesday will be even hotter. Highs will reach the 90s for most areas, with some places like Helena and Missoula hitting the upper 90s. Wednesday will be the hottest day of the year so far as afternoon temperatures reach the upper 90s and low 100s. West wind will increase to 15mph in the afternoon, drying vegetation out more and leading to increased fire danger. Thursday will be hot, dry and breezy with highs again near 100. A weak front will drop south on Friday cooling temperatures off by a few degrees but it will still be hot. Highs will be in the 90s. This weekend will be hot but a few isolated thunderstorms and partly cloudy skies should keep temperatures in the 90s. Isolated thunderstorms on Saturday and Sunday could provide some briefly cooler air with rainfall. These thunderstorms will not be dry, but lightning could reach out beyond the areas of rain that could spark new wildfires. A few isolated thunderstorms are possible Monday as well. This heat likely will continue until the final week of July, so this heat wave could last more than 2 weeks. Remember to stay hydrated and find ways to cool off. Check on your neighbors and pets. These are the dog days of summer.

Stay cool,
