The warmth this month has been more impressive than some might think around these parts, especially with respect to daytime highs. Should finish the month with a monthly mean max of 55° which would be good for 6th warmest on record, and is closer to an average April than March.
Lows haven't been as warm though. It seems like in recent years a lot of the warm Marches have featured quite large diurnal ranges with daytime highs carrying most of the warmth, which may seem contrary to expectations.
