Note:  Going into the final day of the month — May 2018 ranked as warmest May on record at Duluth, Minnesota with an average temperature of 57.5 degrees.  It’s likely with the above average temperatures we had today that May 2018 won’t drop out of the number one ranking.

Weather Synopsis

Mostly cloudy skies today in far northern and northeast Minnesota where some spotty rain showers have been occurred today, the rest of the area saw partly to mostly sunny skies.  Highs on this final day of May 2018 were in the low 70s to near 80 degrees with cooler 60s in far northern Minnesota due to the thicker cloud cover and showers today.

The big weather story for the next few days will be much cooler temperatures.  A cold front will pass through the Northland tonight with winds turning northeast behind this front.  High pressure will build into Hudson Bay Canada for Friday and Saturday while low pressure approaches from the west.  The pressure gradient will tighten between the high and low, and this will cause a gusty northeast wind especially near Lake Superior for Friday through at least Saturday morning, wind gusts from 20 to 30 mph are likely with some higher gusts possible.

925mb temperatures which ranged from +16 to +20C in northeast Minnesota and northwest Wisconsin late this afternoon will drop to +2 to +8C on Friday with the coolest readings near Lake Superior.

Lows tonight will be in the 40s and 50s with highs Friday holding in the 40s and 50s, but areas farther away from Lake Superior should make it into the 60s.

Rain is expected to move into western portions of the Northland late Friday night or Saturday morning with rain then advancing farther east Saturday afternoon.  Rain should then continue Saturday evening before ending from SW-NE later Saturday night or Sunday morning the way it looks now.  Low pressure and a rather strong upper level trough moving east out of the northern Plains will pass through the upper Midwest over the weekend and this will give us another round of rain.  PWATS ahead of this system are expected to range from 1.25 to around 1.50 inches on Saturday so some heavier pockets of rainfall are possible.

Note:  There should be a period of low clouds and possible fog/drizzle that moves inland off Lake Superior later this evening as the east wind develops, the low clouds should burn off Friday as drier air advects down the lake.

Forecast for Duluth and Superior

.Tonight…  Turning breezy.  Partly to mostly cloudy.  Some fog or drizzle is possible from late evening into the overnight hours.  Low 40 to 45.  Wind north to northwest at 10 to 15 mph, becoming northeast at 15 to 30 mph before midnight.

.Friday…  Breezy and cool.  Mostly cloudy early followed by some clearing.  High 47 to 52.  Wind east to northeast at 15 to 30 mph.

.Saturday…  Breezy and cool.  Mostly cloudy.  Rain developing especially during the afternoon.  High 43 to 48.  Wind east at 15 to 25 mph.

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.

Weather Synopsis

Expect occasional rain and thunderstorms in northeast Minnesota and northwest Wisconsin through Thursday.  Thunderstorms are most likely this evening, Wednesday afternoon and again Thursday afternoon.  Instability won’t be quite as high Wednesday or Thursday as it was today, so the potential for severe thunderstorms is lower, but still can’t rule out a few strong to marginally severe thunderstorms on Wednesday.  All thunderstorms will produce lightning.  Heavy rainfall is also expected at times, and its possible that there could be some localized flooding that develops in parts of the Northland through Thursday especially in areas that get multiple rounds of thunderstorms.

The storm environment for this evening consists of CAPE values of 1000 to nearly 3000 j/kg along with mid level lapse rates from 6.5 to around 7.0 c/km.  Plenty of moisture available for storms with dew points in the 60s and PWATS from 1.25 to 1.75 inches.  The negative just like its been for the past few days is the lack of stronger winds aloft and weak wind shear, storms will tend to gust out, weaken, then new storms develop on the the leading edge of the cooler outflow boundaries.

Lows tonight and Wednesday night will be in the 50s and 60s with highs Wednesday in the 70s and 80s, highs Thursday mainly in the 70s.

Near Lake Superior expect much cooler temperatures because of a stronger lake wind which will continue through Wednesday evening.  Lows will be in the 40s to around 50 degrees with highs Wednesday in the 50s.  Areas of fog could also develop near Lake Superior later tonight into Wednesday.

Weather Synopsis

Upper level ridge of 5820 meters continues to cover the central Plains, north to the upper Midwest and east through the Great Lakes.  The airmass underneath this ridge remains unseasonably hot with 925mb temperatures this afternoon of +20 to +30C from western/central Canada, south into the central Plains.

Showers and thunderstorms which impacted some parts of the Northland late last evening into this morning moved out before Noon with mainly clear to partly cloudy skies in our area this afternoon.  Another very warm day with highs in the lower 80s to upper 80s although it was cooler near Lake Superior with temperatures in the 60s to lower 70s today.

The weather pattern won’t change a whole lot through Wednesday.  Expect warm and muggier conditions away from Lake Superior with low temps tonight and Tuesday night in the 50s and 60s with highs Tuesday and Wednesday in the 70s and 80s with a few locations close to 90 degrees Tuesday afternoon.  Dew points are expected to be in the 60s.

Near Lake Superior it will be cooler thanks to an easterly breeze off the lake, this will lead to low temps in the 40s and 50s tonight and Tuesday night with highs Tuesday and Wednesday from the lower 50s to middle 60s.  Areas of fog could also develop at times through Wednesday.

A frontal boundary over southern Minnesota today won’t be moving much through Wednesday while a cold front approaches from the NW on Wednesday.  Plenty of moisture and instability will remain over the upper Midwest which will help to produce more scattered showers and thunderstorms from tonight through Wednesday night.  Heavy rain and lightning will be the biggest threats from these storms with at least some potential for flooding where or if thunderstorms train over the same location for a few hours.  Note:  There is also a risk for a few strong to severe thunderstorms tonight, and again Tuesday afternoon/evening with strong wind gusts and some hail possible with the stronger thunderstorms.

Forecast for Duluth and Superior

.Tonight…  Clear to partly cloudy this evening followed by partly to mostly cloudy skies late.  Scattered showers and thunderstorms possible.  Low 50 to 55.  Wind east at 10 to 20 mph.
