As we enter the last third of April, the pendulum swings toward some BN again. Several early April days were BN but since then there has been a 10+ day stretch of AN. MDT currently stands exactly 4 degrees AN but expect this to get chopped back a bit over the last 10 days of the month. A real chilly one less than a week away on the GFS. Icon concurs with the GFS as a trough pivots through but the CMC not as cold that day but chilly others. 18Z Teams are BN every day at 18Z on the GFS except April 30th.
