Winter to Spring Weather Outlook

While the calendar shows Spring to be starting towards the end of the week, the GFS model is suggesting that Winter will hang on a bit longer.

Following a warm start on Monday, several cold fronts will move through Tuesday into Wednesday and the upper air flow will become the somewhat amplified reminiscent of the pattern that gave us our cold weather through much of February.

While it will not be anywhere as cold, temperatures look to be below average (with some warmer breaks) through the end of March.  No major storms are predicted right now,  but getting some additional snow isn’t out of the question.  Stay tuned.

Winter Weather Outlook

An uncertain forecast. #PAwx   A shift is expected to occur in the jet stream during this coming week and the models are having a tough time predicting the path of the next storm.

Originally, low pressure was expected to move from the US Southwest to the Atlantic coast and then move up as a nor’easter Tuesday night into Wednesday.

Things have changed and now the storm is expected to move up and straight off the coast to our south Monday night into Tuesday morning, ending late morning Tuesday.   Different timing and different amounts of snow.  The GFS has a QPF of about 0.20 inches water, so 2-4 inches is the best guess.

A low confidence forecast right now.
