An interesting development for early April….
Over the past week, the GFS has consistently shown the development of an amplified upper air trough for the eastern US allowing cold air to filter into our area for the weekend. Additionally, the GFS has been showing a mid level vorticity to dive down through the upper trough, bringing precipitation in the form of snow to our area from daybreak Saturday through the early afternoon. The GFS has a QPF of over 0.30 inches water. This could potentially translate into an inch or two of snow on grassy surfaces by the end of the day.
The vorticity is expected to develop into a coastal low pressure system, but currently expected not to linger.
Thursday PM Update: Latest model data still supports very wet snow for Saturday morning. It’s not likely (with current surface temperatures) that there will be an accumulation that affect travel, but some accumulation is possible on grassy surfaces. Current NAM QPF is 0.39 inches water. An interesting weather event for early Spring, after what was a rather easy-to-take winter.
