High Temperatures in Chicago . . .

It's March in Chicago and the average temperature has been hovering between 75 to 85 degrees for the last week.  The Spring plants are all in bloom, the grass is green, the birds are singing; and while this is a treat, I have to wonder what is around the corner.  Is this global warming or a fluke?  Since its March do I move my houseplants outside and start planting vegetable seeds or hold out for the snow to return?  Mother Nature is setting records in the Mid-West, does that mean a draught come true summer?  For now we will make the best of the weather, sit outside for lunch, use the patio set at night for dinner and plant the seeds in anticipation of this warm weather continuing.  I might as well start early, I can always purchase more seeds.  In fact on Friday I will be ordering online from High Mowing Organic Seeds.  I'll be sure to purchase more than could ever possibly be planted in my small garden, because dreaming of what could be growing in my garden half the fun!  Cheers from Chi-town.
