The National Weather Service has just issued a “heavy snow” warning for the Minneapolis Saint Paul Airport:
THE NATIONAL WEATHER SERVICE IN THE TWIN CITIESCHANHASSEN HAS
ISSUED AN AIRPORT WEATHER WARNING FOR…
MINNEAPOLISSAINT PAUL INTERNATIONAL AIRPORT MSP
* VALID FROM NOON TODAY TO 4 PM CST THIS AFTERNOON
FOR THE FOLLOWING THREATS…
* SNOW FALLING AT A RATE OF 34 INCH OR MORE PER HOUR
LIGHT SNOW WILL ENVELOP THE TWIN CITIES METRO AIRPORT SHORTLY BEFORE
THE NOON HOUR. SNOWFALL RATES OF UP TO THREE QUARTERS OF AN INCH
PER HOUR ARE LIKELY BETWEEN NOON AM AND 430 PM. SNOWFALL
ACCUMULATION OF NEAR AN INCH SHOULD BE EXPECTED.
This invites some math. If the rate of snowfall is “up to” 3/4 of an inch per hour, and the snow will last for four hours and the total accumulation is near an inch, for how long would the rate of snowfall be 3/4 of an inch per hour?
