A northern stream trough (black) with some influence from a southern stream trough (red) helped to bring some rain to parts of the Northland today.

This system won’t fully phase, however, as the trough over the Southern/Central Plains moves almost due east instead of turning north/northeast. What this means for the Northland is for drier weather to return on Thursday.
