…Tuesday’s severe weather outlook…
•A few strong to severe thunderstorms are possible Tuesday into Tuesday evening over all of northeast Minnesota and northwest Wisconsin.
•Hazards include damaging wind gusts to 60 mph and large hail to 1.00 inch diameter (quarter size)
•Heavy downpours and cloud to ground lightning are also possible.
Severe threat on Tuesday, June 4 is at a 2 meaning that scattered severe thunderstorms are possible. Short lived and or not widespread. Stay weather aware on Tuesday.
Warm front, cold front and area of low pressure moving through the upper Midwest on Tuesday will interact with a potentially moist and unstable airmass, this combined with added lift provided by the surface fronts will likely result in the development of scattered convection across the Northland Tuesday.
Winds aloft on Tuesday don’t look terribly strong per model guidance with a rather weak low level jet as well, mid level lapse rates also look rather poor, generally around 6.0-6.5 c/km, this could limit the severe threat to some extent, but instability could be on the high side with CAPE possibly in the 1500-3000 J/kg range during the afternoon-evening hours, so we could have quite a bit of fuel/potential energy for a thunderstorm to tap into during the afternoon/evening hours.
18z HRRR model 6-3-19
Radar forecast valid from 7 AM Tuesday to 1 AM Wednesday.
Scattered showers and thunderstorms are possible across the Northland Tuesday into Tuesday night.
Low level moisture will be on the increase Tuesday with dew points climbing into the upper 50s to middle 60s over most of the Northland while Precipitable water (PWATS) increase to around 1.20 to 1.80 inches per model guidance, this increases the potential for heavy rainfall and possibly some localized flooding where thunderstorms occur Tuesday/Tuesday night.
