September 2012: One for the record books
Another month, another near record in Minnesota.
With a paltry .30″ rainfall this month, this will go down as the driest September in 130 years, and the 2nd driest on record in the metro. Only 1882 (barley) squeezed out less rain with .27″.

Signs of a trend?
It’s hard to say, but with 3 of the past 4 Septembers among the top 6 driest on record it seems our early fall periods are trending drier in Minnesota. I’ve spoken with Mark Seeley about this, and he indicates there is a distinct trend toward drier autumns in Minnesota.
Last fall was the driest on record, with just 1.36″ precipitation in the metro.
Details from the MN Climate Working Group.
September through November 2011 was the driest Twin Cities meteorological autumn in the 141 year modern record. The September through November 2011 precipitation total at the Twin Cities International Airport was 1.36 inches, a negative departure of 5.92 inches from the 1981-2010 normal of 7.28 inches.

With a “dry bias” continuing into the first 2 weeks of October, it appears we may be well on the way to another dry autumn in Minnesota.

The incredible “6-Month Summer” of 2012? Welcome to Omaha!
Yes I may be overstating it a bit, but this has been a remarkable run of warmth since March. March was the warmest on record, and this was also the warmest spring on record at MSP, St. Cloud & Eau Claire.

Take a look at the temps vs. average at MSP Airport since March 1st.
March +15.5F (Warmest on record)
May +4.6F (10th warmest)
June +3.5F (13th warmest)
July +6.4F (2nd warmest)
You can see it’s not a stretch to say we’ve been feeling summer like weather for almost 6 months in the metro.
In fact the average temp since March 1st at MSP Airport is +4.91F. That’s about like living in Omaha, Nebraska where the average annual temperature is about +5F warmer than the Twin Cities.
WCCO Radio & Strib sports legend Sid Hartmann always used to threaten that the Twin Cities would be just a “cold Omaha” without professional sports. Sid, it turns out we got Omaha’s relatively balmy weather instead!

Reality Check Ahead: Cold front arrives Wednesday
Enjoy the string of 70s through Tuesday. The next cold front comes sailing south from Canada Wednesday with a chance for a few showers, and much colder weather.
Highs may not climb out of the low 50s late next week.
It may finally start feeling like October around these parts late next week.
Until then enjoy…and have a great weekend!
