Yes it does warm up at times during the 2nd half of April but will it be enough to get us back above average for the month? Pretty big temperature departures so far this month, it will take a couple shots of unseasonably warm temperatures to erase the current temperature departures.

Forecast Discussion for NE Minnesota and NW Wisconsin
Short Term Forecast - Confidence: High.
Tonight (April 9)
Low pressure will move into the Upper Midwest tonight while a strong southerly low level jet develops out ahead of this system which leads to a warm advection pattern tonight. Mostly cloudy skies are expected with a chance for snow and mixed showers, precipitation that does fall tonight should remain fairly light although somewhat heavier snow could affect the Arrowhead of Minnesota with a few inches of snow accumulation possible mainly over Cook County. Low temperatures will be in the 20s and 30s with teens before Midnight in far northeast Minnesota. Winds will remain out of the south or east at 10 to 20 mph.
Sunday and Sunday night (April 10)
Low pressure will pass north/east of the area on Sunday while a cold front pushes through the Northland tomorrow morning. Mostly cloudy to partly sunny skies for Sunday with a few snow, sleet or rain showers possible mainly during the morning. Highs on Sunday will be in the 30s and 40s with near 50 degree temperatures possible in far southern parts of the Northland. Winds will be out of the south, east or west at 10 to 20 mph.
Mostly cloudy skies Sunday night with a chance for flurries or snow showers. Lows will be in the 20s with teens in far northern Minnesota. Winds will be out of the west or northwest at 15 to 25 mph.
Extended Forecast - Confidence: High.
Monday through Wednesday (April 11-13)
Flurries or snow showers are possible on Monday with highs in the 20s and 30s. Lows Monday night will be in the single digits to around 20 degrees.
Mainly dry conditions are expected for Tuesday and Wednesday with highs on Tuesday in the 30s and 40s with highs on Wednesday in the 40s and 50s but it will be cooler near Lake Superior. Lows Tuesday night will be in the 20s and 30s. Note: There is a chance for some patchy light snow in parts of the Northland Tuesday night-early Wednesday morning but this doesn't look like a real big deal at the moment.
Long Range Forecast - Confidence: Medium to High.
Above average temperatures are expected during the long range although an easterly wind will keep it cooler near Lake Superior. Looks mainly dry during the long range but a storm will be developing over the Rockies and Plains and this system may affect us sometime during the 17th-19th time frame but there's also a chance for this storm to remain west and south of the Northland which would lead to us staying dry.
