Weather Tidbits for Duluth, Minnesota
-Three days in a row with a sub-freezing low temperature (October 9-11) Have to go back to late April (26-29) for a longer streak than this current one (4 days with a low temp colder than 32 F) Shouldn’t drop below freezing tonight so this current streak looks to end at 3.
-Going into today, the average temperature for October was 49.8 degrees (+2.3 degrees warmer than average)
-Low temperature this morning was 26 degrees which ties with 1917 and 1909 for 5th lowest minimum temperature on record for October 11. The record low temperature for October 11 is 21 degrees set in 1936 and 1919.
Southeast wind on the back side of high pressure which has shifted off to the east is resulting in warm air advection and a gradual increase in moisture which has led to an increase in clouds late this afternoon over east central Minnesota and far western Wisconsin but sunshine continued in northern Minnesota and over portions of northwest Wisconsin at 5 PM today. Highs today were generally in the 50s with a few locations getting into the low 60s.
Southerly flow will persist into Thursday night which will result in milder temperatures but also more cloud cover compared to recent days. Will also have some areas of drizzle late tonight into Thursday, and possibly again late Thursday night. A cold front will move east out of the northern Plains and is forecast to move through the Northland early Friday morning, just enough lift near this front to squeeze out some drizzle and possibly a few light rain showers but that should be about it.
Low temperatures tonight will range from the lower 40s to lower 50s. Highs Thursday will be in the 50s to lower 60s.
Friday looks dry under partly to mostly cloudy skies with highs in the 50s.
