...NO CRITICAL AREAS...



...Synopsis...

Amplified mid-level flow will continue across the CONUS today as a

broad upper low gradually moves eastward. Western US ridging will

also amplify, forcing stronger flow aloft over the northern US. At

the surface, a cold front will move south across the Northern Plains

and Great Lakes. Relatively mild and wet conditions will prevent

broader fire-weather concerns over much of the country, though a few

drier thunderstorms are possible along the cold front.



...Northern Plains and Great Lakes...

As the cold front progresses southward, isolated thunderstorms are

likely to form along and ahead of it through the heat of the day.

With relatively modest moisture (PWAT values around 0.8 inches)

these storms are expected to be relatively high based. A mixed mode

of wet/occasional dry storms is possible with some lightning risk

over recent dry fuels. While coverage of the drier storms appears

limited, increasingly dry and breezy conditions behind the cold

front could allow for some lightning ignitions and localized

fire-weather concerns.
