Morning Update
Today is our rain day as advertised and it may impact your travel plans, as this spreads in during the morning. Low Pressure redeveloping along a cold front will enhance the downpours and may include some rumbles of thunder early this afternoon. Along with that, temps may boost up into the evening. After the rain abruptly ends, strong winds will pick up Monday and temps drop back down.
Active Storm Pattern
GFS: Sunday Morning to Wednesday Night
The main theme in the short term is that we are in a pattern with a storm every 3 days, but remain on the warmer rainy side (for now), while the mountains get rain, ending with a few inches of fresh snow each time.
Today’s Weather
Morning Temperatures
Morning Surface Weather
What we have this morning is an Occluded Low. A typical Low Pressure has a warm and cold side. This occlusion is when the cold air wraps completely around the core circulation. This cuts off the warm air, and in this case… shifts the energy to the southeast, in a location known as the Triple Point. This is where the old cold front, now occluded (purple), meets up with the cold front remains (blue) and new warm front (red). This is where a new Low Pressure is likely to form.
That Triple Point and new circulation will ride over Maryland in the middle of today. This is why we expect heavier rain and some thunder as it passes by.

Rain showers earlier will be spotty. Steady rain will expand from west to east through the morning.
