Last gasp of winter - snow

This time of year the upper midwest is subject to warring weather fronts generally from the south west and the northwest.  The latter tend to bring drier but colder weather, while the former bring in moisture, which falls depending upon the temperature as either a liquid or a solid or a wintery blend of both.  These tend to form long narrow weather tracks that can hit or miss us depending upon just where the track is.  This year has been rather snowy, and last night we got probably 3 inches that will melt very soon as warmer air replaces the colder.  A colleague new to these parts commented on the changeable weather and how sad it was that all their shoots got snowed on.  Snow is a great insulator and spring shoots do very well beneath a blanket of snow.  TPP worries more about shrubs and trees buds getting their tips frozen if the temperature gets too cold.  People are already asking about tomato and chili peppers plants and even a minimal freeze with kill these tropical plants.  Stick with the mustard family, the coleworts, and lettuces and other cold weather greens for at least another month unless you use something to cover them as they grow.  The good old boys used to say if your peas didn't get snowed on they weren't planted early enough. Of course our friends that moved to the "upper peninsula" can only dream of spring.
