Goes-16 visible satellite loop from Sunday, June 16, 2019.
Still seeing an upper level area of low pressure off to our northwest today, this system will continue its slow eastward track into the upper Midwest and upper Great Lakes through Tuesday. This system will bring a few showers to the Northland tonight, Monday and again on Tuesday. Note: Some of us will probably remain dry through Tuesday, while others get some showers from time to time. There is also a chance for a few thunderstorms especially on Monday as instability builds to around 100-500 J/kg with steepening mid level lapse rates to around 7.0 c/km. Mid level winds are favorable for storm organization on Monday (30-50 knot westerly flow) with upper level winds 70 to around 100 knots over the area, the limiting factors for strong storms appears to be the lack of instability and moisture on Monday.

18z HRRR model 6-16-19
Radar forecast valid from 7 PM Sunday to 7 PM Monday.
The pattern we’re in remains favorable for the development of isolated to scattered showers through Monday evening, but widespread heavy rains are not expected, instead shower coverage will remain spotty, meaning some of us get hit, others get missed.

Conditions in the atmosphere have become favorable for the development of brief weak funnel clouds until around sunset in the dark red outlined area on map. Note: These types of funnel clouds are usually short-lived and weak and rarely reach the ground.

Not much change in the upper level pattern this week. Little if any chance that will get any very warm/hot temperatures into our area this week, instead we’re looking at below to near normal temps most of this week.

12z European ensemble model 6-16-19
There continues to be some signs showing up in long range model data for a pattern change during the last week of June. An upper level ridge could develop across the Southern U.S. while possibly expanding north with time, this type of pattern if it develops would become favorable for clusters of strong to severe thunderstorms which would ride SW-NE on the north side of the upper ridge/capped airmass. If this ridge can build far enough north, then the final week of June could turn quite warm and humid across the Plains, Ohio Valley, parts of the eastern U.S.; and possibly into the upper Midwest and Great Lakes.
