If your field is near one of Environment Canada’s radar
stations, you can access weather
radar maps
in video format which show the past 1hr OR 3hrs of precipitation
events.  These maps can help growers
review where and how much precipitation fell nearby.
We included screen shots of Environment Canada’s webpages
below and we added red text and arrows to help.

The map below is
the first of the predicted emergence maps for the wheat midge for
the 2015 growing season.  Remember, wheat midge emergence and flight will also be affected by precipitation events and wind.  Even so, if you are hoping
to catch the very first wheat midge as they start to emerge, keep watching the map below for areas
that will be highlighted below as lime-green (i.e., 600-693 DD). 
Rain fell over
the past five days so watch for the updated map in the Weekly Update which
should be available by Thursday.
