Light At The End Of The Tunnel? Think Again.
March sure has been a wild month! Indianapolis is running close to 4° below average on the month with around one foot of snow. The highlight was obviously the 10.2″ of snow that fell last Saturday.
Largely this was driven by the return of blocking- something that has been missing most of this winter and, for that matter, the past couple of winters. Note the prolonged, sustained negative NAO. As we’ve written in the past, the NAO, or North Atlantic Oscillation, is the “king” this time of year. In late winter and spring, negative NAO phases will result in cold periods, even in the face of potentially warmer signals from other, less dominant, teleconnections.
As we look ahead, we don’t really see any significant changes with the forecast NAO into mid-April.
To no surprise, the pattern remains colder than average over the next couple of weeks, overall.

With all of the cold around, it should also be no surprise that at least the threat of additional accumulating snow is on the table. In fact, an item of “interest” will eject out of the Rocky Mountain region and into the Plains and eastern half of the country in the 8-10 day period. It’s far too early for specifics, but at least the potential of accumulating snow is present next weekend across the Ohio Valley.

Looking Ahead To Close March And Open April: Cold Set To Return?
Before we discuss some of what has our attention as we move through the next couple of weeks, check out this cool visible satellite image from this morning. The snowpack shows up nicely. It’s also neat to see the high resolution modeling understand where that snow pack is and the associated cooler forecast highs compared to areas south and north that didn’t see the heavy snow Saturday.
As we look ahead, a wet week is in store for the region. Periods of widespread rain, heavy at times, will come at us in waves:
- Monday evening-Tuesday
- Thursday
- Next weekend, including Easter
When totaled up, widespread 2″ totals can be expected, with locally heavier amounts.
After a brief relaxation in the unseasonably cold regime, well below average temperatures are expected to return as we move through early April. It’ll feel more like winter than spring through the better part of the first half of the month.
It’s also too early to think about yesterday as the last snow of the season. Given the early April look, it wouldn’t surprise us if an additional snow event or two came along…
(As a reminder, you can always catch our most up-to-date 7-day forecast in the top left of the homepage).

Heavy, Wet Snow Continues For Most Of Central Indiana…
Right out of the gate, our ongoing snowfall forecast remains unchanged:
Heavy, wet snow will continue through the majority of the day for central Indiana. At times, banding will produce snowfall rates in excess of 1″ per hour. On the southern periphery of the snow zone, a mixture of sleet and rain will mix in at times, but as precipitation rates increase, dynamic cooling will keep the predominant precipitation type as snow even on the southern tier.
Despite marginally cold pavement temperatures, the heavy snowfall rate is having no problem accumulating on area roadways and multiple traffic hazards have already been reported this morning, particularly in Boone County. If you don’t have to travel today, it’s best to remain at home.
As temperatures fall into the lower to middle 20s tonight, refreezing will occur and areas of black ice will develop, especially on untreated, secondary roadways.
The “big dig” will begin in earnest Sunday morning as dry conditions return and the added increasingly strong March sun angle will also help in clean up efforts by afternoon.
By the way, please keep your snow reports and photos coming!
