Three disturbances showing up on water vapor satellite imagery today. The one that will affect us later tonight is currently moving into southwest Manitoba and will dive SE through the night. The disturbance over southern Wisconsin has been producing stronger thunderstorms today while the system to our NE over northeast Ontario Province sits and spins in that general area.
Radar loop ending at 4:55 PM CDT today (June 19, 2017)
NW flow aloft continued today with low pressure just east of Hudson Bay Canada with high pressure over southwest Canada -- Daytime heating, some cold air aloft and lingering moisture across the area led to another day with a few pop up showers under mostly cloudy to partly sunny skies. Highs today ranged from the mid to upper 50s in far northern Minnesota to the 60s near Lake Superior, east central Minnesota and in all of northwest Wisconsin.
A strong disturbance currently moving into southwest Manitoba Province late this afternoon will continue to dive SE, moving through Minnesota later tonight. This system will bring some showers and isolated thunderstorms to parts of the Northland from late this evening into early Tuesday morning. There will also be a few showers generated by daytime heating that will carry over into the early evening hours -- Partly to mostly cloudy skies tonight with lows ranging from the mid 40s in the cool spots up north to the 50s elsewhere.
High pressure builds into the upper Midwest Tuesday resulting in a mix of sun/clouds. Still can't rule out a few spotty showers tomorrow but coverage should be a lot less compared to the past few days. Highs Tuesday in the 60s to lower 70s.
The next chance for showers will be on Wednesday as low pressure along with a warm front and cold front move east out of the northern Plains -- Elevated instability will increase a bit especially Wednesday night and this is when we could have a few thunderstorms along with the rain showers but at the moment this doesn't look like a favorable setup for a lot of thunderstorms up in our area.
Note: The high temperature so far today at International Falls, Minnesota (59 degrees) if this holds, then this will tie with 1967 for second coldest high temperature on record for June 19th. The coldest high temp on record for June 19 is 58 degrees set in 1969, 1949 and 1926.
