Those of us wanting Indian Summer this year may have to settle for “Indian Spring.”
Sunday’s 58 degree high in the metro was the warmest day in 10 days, and maybe the warmest of the rest of the year. But there are signs that we may return to the 50s yet again before the snow flies for real.
Speaking of snow, is that a little slush in the (metro) forecast for Tuesday morning? Yes. But we can be thankful warmer air will filter in and change any precip back to all rain tomorrow.
There will be enough slushy snow to shovel in the western Dakotas again this week.
Here’s a look at how the forecast snowfall lays out this week according to the National Oceanic and Atmospheric Administration’s North American Mesoscale model.
The NAM is aggressive, and probably overdone for Minnesota. But I can’t rule our a couple inches of slush west of the metro Tuesday morning as close as Willmar.
Late October Panhandle Hook
If this were December we’d be busting out headlines for 6 inches to 12 inches of snow this week. The incoming low pressure system is tracking from the Texas/Oklahoma Panhandle region toward the Upper Midwest by Thursday morning.
It looks like mostly rain for Minnesota this week. Overall rainfall totals look to be mostly between a quarter inch and three quarters of an inch with some 1 inch-plus totals possible under the heavier rain band that roll in Wednesday evening.
The heaviest rains will fall to the south, where some drought busting 2 inch to 4 inch rainfall totals may drench parts of Iowa and the Midwest. Here’s NOAA’s 3 day rainfall forecast.
No Indian Summer in 2013?
We all look forward to the last surge of warmth this time of year, Believe it or not, Indian Summer does not occur every year in Minnesota.
Here’s the definition of Indian Summer from the American Meteorological Society.
A period, in mid- or late autumn, of abnormally warm weather, generally clear skies, sunny but hazy days, and cool nights.In New England, at least one killing frost and preferably a substantial period of normally cool weather must precede this warm spell in order for it to be considered a true “Indian summer.” It does not occur every year, and in some years there may be two or three Indian summers.The term is most often heard in the northeastern United States, but its usage extends throughout English- speaking countries. It dates back at least to 1778, but its origin is not certain; the most probable suggestions relate it to the way that the American Indians availed themselves of this extra opportunity to increase their winter stores.
