Cool and dry: from weather expert Jim Lushine:
In addition to a relatively long cool spell, we also are in for a very dry spell as well.
But the rainfall that has fallen in the month of January at Palm Beach International Airport already has exceeded the normal rainfall for the months of January and February, combined.
With the dryer air comes increased evaporation, so the grass is going to get crunchy in about a week. Those with sprinklers may want to increase the frequency of watering.
