High pressure is slowly transitioning towards the Ohio Valley today, which will lead to a slight shift in the winds towards the northwest.  Other than the wind shift, conditions will remain rather quiet throughout the northern Mid Atlantic, as least for now. The water vapor satellite picture this morning shows an interesting separation between the Sub [...]

This is the second afternoon of perfect conditions with clear skies, low humidity, and temperatures pushing into the upper 50’s to lower 60’s along the immediate coast and lower to mid 60’s throughout the rest of the Philadelphia and New York City metropolitan areas. The tranquil conditions will continue into this evening as temperatures slowly fall [...]

After a February and early March that produced historic heavy snowfall, heavy rain, flash flooding, wind damage, and all sorts of other issues; the Philadelphia and New York City metropolitan areas finally are going to get a nice and well deserved break. High pressure this morning is producing clear skies with temperatures in the mid 30’s [...]

It’s amazing how much weather conditions can change in less than 24 hours!  Just this morning, overcast conditions dominated and the regions was still soaked from the five day rainfall event!  This afternoon, conditions could not be much different with clear skies and much warmer temperatures as highs blew past forecasted temperatures into the upper 50’s [...]

For the first time in five days I can say that no rain is falling at any locations throughout the New York City and Philadelphia metropolitan area! The IR satellite picture basically tells the tale for today as clouds will continue to break up and skies will clear throughout the region.  The slow moving, rainfall record [...]

There are signs that the low pressure system that has brought over 3 inches of rain or more throughout the New York City and Philadelphia metropolitan area is finally starting to exit. Pressure rises are being observed throughout the northern Mid Atlantic ranging from 1 to 3 MB per hour and the center of the low [...]

It’s the low pressure system that just won’t quit. Another round of moderate to heavy rain is currently moving through southern New England and is expected to rotate through Connecticut, Long Island, the New York City metropolitan area, much of New Jersey, and eastern Pennsylvania.  The heaviest rain is expected to be focused along the immediate [...]

Another day and more rain.  That’s the best way to describe this dreary Monday morning.  Once again, the upper low that has plagued the Philadelphia and New York City metropolitan area since Thursday continues to drive Atlantic moisture into the northern Mid Atlantic. A 996 MB surface low roughly 200 miles southeast of Long Island is [...]

The area of low pressure responsible for widespread flooding, coastal flooding, and wind damage is finally starting to weaken over the central Mid Atlantic this morning. The surface low and upper level structure of the storm have become vertically stacked.  What this means is the surface, 850 MB, 700 MB, and 500 MB low pressure systems [...]

The area of low pressure that has produced widespread flooding and wind damage continues to sit just southwest of the Philadelphia metropolitan area over central Maryland. The low pressure system is currently drawing an area of showers and thunderstorms into the forecast area from the Atlantic.  These showers and thunderstorms are capable of heavy downpours, wind [...]

Heavy rain and winds sustained at 15 to 25 mph have been observed since last night as the first round of heavy rain continues to move through the Philadelphia and New York City metropolitan area. A break in the heavy rainfall is expected for late this morning into the early afternoon hours as a new coastal [...]

The coastal low is clearly becoming the primary low pressure system this evening as very strong lifting is developing off the coast along with a classic satellite signature of cyclogenesis. The radar this hour is clearly showing an area of very heavy rain just south of Cape May, New Jersey moving north towards the coast.  The [...]

The rain is here and it is not going to be stopping any time soon through this weekend, which will be a perfect time to catch up on some movies, a good book, or perhaps finally conquer a very difficult video game.  What ever you do this weekend, it likely will not be done outdoors. Light [...]

An area of low pressure off the South Carolina coast this morning is expected to intensify and slowly move north towards the New Jersey coast over the next three days.  This low pressure system is expected to produce heavy rainfall, strong winds, and the potential for some coastal flooding along the New Jersey coast and the [...]

The storm is starting to organize over the Plains, Gulf Coast, and Southeast.  The model guidance at this point is in very strong agreement for a widespread heavy rainfall starting tomorrow afternoon and continuing on through Sunday morning with rainfall amounts by Monday morning ranging from 2 inches to as much as 5.5 inches of rain. [...]

The temperatures may be warmer, but the active storm track that the Philadelphia and New York City metropolitan area experienced in February is returning once again. The easterly fetch developing at the mid and lower levels of the atmosphere is already influencing the northern Mid Atlantic as Atlantic moisture moves into the coastal plain.  The combination [...]
