Watering Our Drought: How Sunday's snow will help

Our #springsnow dropped some impressive totals across region to end the first weekend of spring on a winter note. Our biggest snow so far for this anemic winter season is still the 4.2" that fell on December 26 and 27, 2014. For the metro, this Sunday's snow made a good faith effort to eclipse that late December snow event but once again came up on the short end of the snow stick.

The good news is that the big wet flakes will lead to a slow watering of our moisture starved ground across Minnesota. One thing that hydrologists look for is the moisture content of that snow that is on the ground. After doing some simple mathematical researching, I have determine the ratio of water to snow was approximately 15-.5 to 1 across the metro and 12 to 1 across areas to our south. This means that on average, every inch of water would result in 12-15 inches of snow. Since we did not see more than a foot, in most places it was close, we received less than an inch of water from this latest snow event. Check out the conversions on our Sunday-Monday snow totals below.

This is great news as the dreaded "drought" is back in our weather vocabulary. The key factors that will help us retain as much of this moisture as possible are as follows.

(1) A SLOW MELT – thank the cloudy skies and lower 40s for that.

(2) THAWED EARTH - a lot of non-frozen topsoil allowing for absorption rather than runoff. This is important because any measurable moisture, classified as 1/10" or more, can have beneficial effect on our drought.
