Central Montana Heating Up for 80 MPH Thunderstorm Gusts — SevereWX

Thunderstorms are poised to surge across central Montana this evening, fueled by scorching mid-to-upper 90s heat eroding lingering inhibition.

The Storm Prediction Center's Mesoscale Discussion 1730 highlights early convective attempts in southwest to central Montana giving way to more sustained activity. As storms spread eastward into hotter, deeply mixed air, severe wind gusts of 65-80 mph become likely, especially in areas untouched by prior outflows. Mid-level winds around 30-35 knots could foster loosely organized clusters capable of damaging downdrafts.

Peak threats include wind gusts to 80 mph and hail up to 1.25 inches. Coverage should ramp up over the next 2-3 hours, prompting a 60% chance of watch issuance within the valid period (251950Z - 252145Z).

This setup differs from earlier terrain-influenced storms, with downstream heating key to unlocking potential. Residents from Great Falls eastward should monitor trends closely.

Stay prepared: Secure outdoor items, avoid travel under storms, and have multiple alert sources ready. Check SPC for updates.
