Weather Synopsis
What a day! Alberto which was a sub-tropical system over the Gulf of Mexico a few days ago has been moving north, and today Alberto has reached Indiana with still a very nice swirl/representation apparent on radar and satellite imagery. Deep tropical moisture is advecting northwest from Alberto and into the Northland, and is interacting with an approaching upper low/trough moving east out of the northern Plains — Net result has been for widespread rain and showers in the Northland today with a few embedded thunderstorms as well, but with extensive cloud cover, this kept the instability down. Cooler daytime highs today compared to recent days with highs today in the 60s and 70s which is near to still above average for late May. Cooler temps near Lake Superior (50s) thanks to the east wind off the lake.
Showers and isolated thunderstorms should gradually diminish across most of the area tonight, although rain and showers could linger most of the night in far northeast Minnesota and near the Ontario border, otherwise expect mostly cloudy skies with areas of fog with some dense fog possible in parts of the area. Lows tonight ranging from the upper 40s near Lake Superior to the mid 50s and low 60s elsewhere.
Mostly cloudy to partly sunny skies on the way for Thursday. Areas of fog early, then a few pop up showers and thunderstorms for the afternoon hours with brief downpours and occasional lightning. Highs Thursday in the 70s with a few locations possibly making a run at 80 degrees if there is enough sun.
Much cooler Friday and Saturday as strong northeast winds develop between a Hudson Bay high and low pressure over the northern Plains — Should have 20 to 30 mph wind gusts near Lake Superior Friday into Saturday morning. Highs Friday and Saturday are forecast to be in the 50s and 60s, but near Lake Superior temperatures could struggle to get out of the 40s especially on Friday. Some rain is possible in parts of the Northland Friday night or Saturday as that aforementioned northern Plains low heads this way.
Forecast for Duluth and Superior
.Tonight… Rain gradually diminishing. Areas of fog and drizzle through the night. Fog could be dense at times. Low 55 to 60, cooler near Lake Superior. Wind east at 5 to 15 mph becoming west toward daybreak.
.Thursday… Mostly cloudy with some sun at times. A few showers or thunderstorms possible during the afternoon. Fog early. High 74 to 79. Wind west to northwest at 10 to 15 mph.
.Friday… Windy and cooler. Partly to mostly cloudy. High 48 to 53. Wind east at 15 to 30 mph.
