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.

The GFS model has been showing the development of an eastern upper air trough, allowing cold air to filter into our area again this coming weekend.

This trough will develop at the same time that moisture is streaming up from the Gulf of Mexico.  As a result, low pressure is expected to develop near us, in the Saturday -Sunday time frame.

With some precipitation occurring at night and with atmospheric thickness levels falling below 540 dm, it is possible that we will see some light snow, unlikely to accumulate, if the precipitation occurs during the night time hours.

Wednesday Update: The latest GFS continues with the possibility of snow, with the timing occurring during Sunday afternoon and evening. It’s not a sure thing, but the models have been somewhat consistent.

It should be noted that the GFS model has been depicting this possibility for almost two weeks.  And it should be noted that a week ago, the Channel 6  weather people emphatically declared no more snow for our area this season.
