SNOW SHOWERS TUESDAY AFTERNOON
March sunshine went to work on this unseasonably cold air Tuesday. The afternoon sun and some influence of the departing snow storm combined to produce afternoon snow showers. The snow showers at time brought sleet and brief drops in visibility. The snow showers will diminish around sunset.
HISTORIC SNOW STORM
After tracking the snow storm for a little more than a week, it sure lived up to its billing. The forecast of 6″ to 10″ through the heart of the state developed as expected. Officially 9.1″ of snow fell Sunday and Monday in Indianapolis. This one storm practically equaled all the snow that fell here last winter (9.8″). The record books have been rewritten. No time in the history of record keeping has this much snow fallen so late in the season. Snowfall for the month has hit 14.5″ and places March 2013 as the fourth snowiest on record. Snowfall for the season is now 35.5″, which is 9″ above normal and 3.5 times more than last year!
CHILL EASES – WARMING TREND THROUGH EASTER
Afternoon high temperatures have struggled under the influence of this large blocking pattern. The chill will ease through the workweek and afternoon temperatures are likely to crack the 50° mark again late in the week and into the weekend. It is not a pattern buster but temperatures that are running 15 to 20 degrees below normal will rebound to just shy of normal Sunday. The 39° high Tuesday marked the 15th straight day below normal.
COLD “GREENLAND BLOCK” NOT BREAKING
The blocking pattern that developed back on Feb. 15 is showing no signs of letting up. The bubble of warm air over the North Atlantic reaches into Greenland and north to the North Pole. This setup forces cold air south into the eastern U.S. and brought about the colder than normal stretch. Thirty-four of the past 40 days (85 percent) have been below normal. This “Greenland Block” looks to hold on over the next 2.5 weeks. While the chill eases over the next few days, resurgent cold air is forecasted early next week. Showers and milder air Sunday will be swept away as an unseasonably strong cold front settles through the state again Monday night.
HINTS OF A SOUTHERN TRACKING STORM SNOW NEXT WEEK?
The U.S. and European long-range forecast charts are hinting at another southern low next week after colder air dives in There is a signal but at this distance only a hint. Bears watching.
