...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE NORTHERN HIGH PLAINS...
...SUMMARY...
The most concentrated corridor of severe storms, including potential
for significant severe wind/hail and a few tornadoes, is forecast
across parts of Montana into southwest North Dakota through this
evening.
...01z Update...
Latest satellite imagery and diagnostic data suggest a weak
short-wave trough is topping the ridge over central MT. Scattered
convection has developed ahead of this feature with multiple
thunderstorm clusters now evident from south-central into eastern
MT. Easterly low-level is maintaining moisture across the northern
High Plains which is contributing to MUCAPE in excess of 3000 J/kg
across much of eastern MT, south of a front draped from west of
GDV-into the Dakotas. With LLJ expected to increase across the
central High Plains into the Dakotas after sunset, a continued
eastward propagation of the overall convective field is likely.
Another notable short-wave trough is ejecting northeast across CO
toward western NE. Scattered strong/severe thunderstorms have
developed ahead of this feature within a favorable zone of low-level
warm advection from north of SNY-west of CNK. This corridor will
remain active, especially as LLJ strengthens over the next few
hours.
