Top 5 Most Subzero Hours at MSP in February
As of 11AM on Tuesday, February 16th, the MSP Airport warmed to above 0F putting us at 226 hours spent below 0F at the MSP Airport this February. Interestingly, through that time period, it was the 4th most on record! It appears that we'll have some additional subzero time AM Wednesday and again AM Thursday. With that being said, we might slide into the 3rd or even 2nd most time spend below 0F at MSP in February. Here are the top 3 spots:
403 hours - 1936
253 hours - 1917
230 hours - 1914
A Little Light Snow Wednesday
Light snow will pass through the region on Wednesday. It won't be much, generally less than 1 inch, but with temperatures still as cold as they are, roads could become icy once again. Here's the weather outlook from AM Wednesday to AM Thursday. Note that most of the snow will fall through the day Wednesday and will be done by early AM Thursday.
Light Dusting of Snow Wednesday; Icy Road Potential
Here's the snowfall potential on Wednesday. Again, most locations will see amounts generally less than 1 inch, but because temperatures will be so cold, roads could become icy once again.
Initial Spring Flood Outlook – Below Normal to Normal Threat
"Current conditions suggest that the threat of major spring flooding is lower than we've seen for a few years, and is close to or below normal. Much will be determined by spring temperatures and precipitation, however. What Do We Know So Far? Soil Moisture is…Normal! After two years of record high soil moisture, 2021 starts with near to a little below normal soil moisture over the entire area, thanks to a dry autumn. This will allow for the soil to absorb more snowmelt once the thaw occurs. Snowpack / Snow Water is Lower We've had near to below normal snowfall over the area this winter, so far. Generally, only around 2 inches of water currently exists in the snowpack, with even less in the upper Minnesota and lower Chippewa (WI) basins. What does this mean? It would take a major increase in snowpack through the rest of the winter, and/or a very quick warmup with heavy rainfall, to create widespread major flooding in the Minnesota/St. Croix/ Chippewa/Upper Mississippi Rivers this season. Recall that we had nearly ideal spring melts in 2019 and 2020 (no extreme temperatures, and extended periods of no rain/snow in March). What will 2021 bring us? Next Updates: February 25 and March 11, 2021."
Extended Periods of Zero or Below in the Twin Cities
"Since 1873, the temperature in the Twin Cities has remained at or below zero for at least four consecutive days a total of 27 times, with the most recent occurrence being a five-day stretch ending January 18th, 1994. The longest such streak on record was seven days, from January 1-7, 1912. The same stretch in 1912 clocked in at 186 consecutive hourly observations with temperatures at or below zero. The stretch in 1994 lasted 142 hours. More recent zero-or-colder stretches include 86 hours from 11pm January 12 to 1pm January 16, 2009 and 93 hours from 5pm January 31, 1996 to 1pm February 4, 1996. How long would a stretch of zero or below weather be to make the top ten list? The mercury would have to stay at or below zero for at least FOUR full calendar days to have a chance of making the list. The last time there was a fairly long stretch at or below zero was from midnight, January 29, 2019 to 5 am on February 1, 2019 for a total of 78 hours."
