OK who ticked off MOM nature this year? Between her 10 snowstorms and over 80 Inches of snow in some spots..She has now decided to put us on the FLOOD WATCH later this week.

Above is the WV image from this evening.. The first things that should pop to you is a potent upper level low over north texas with a ton of juice along the southern jet stream to the south. Note a "tail" like feature going into East Texas.. That appears to be the line of strong storms i mentioned in last night's post that will turn severe as it heads into eastern texas where the best dynamics for severe storms will be met.
Back in the Northeast.. We will watch and wait for this storm to head eastbound. AS the storm presses on..It will interact with a block over Hudson Bay which will allow the storm to stall out. This Pattern will allow various shortwaves to rotate around the main center..All the while tapping into the southern jet juice we saw on the Water Vapor Image above.
The OUTCOME.. Could be very BAD for the Mid Atlantic and Northeast. With a flow from the south and at times off the atlantic we could see a 3-6" rainfall for many.. with 3" being the ideal number from DE coast to Boston coastline..and inland area's going to 6-9" of rain with orographical lift (marine air pressing from the ESE against the MTNS)
Here's the GFS spin on totals:

SO we will continue to update the forecast..Let you know the rivers to watch out for..and please drop advice about roadways you see that flood under these conditions below..

I think you have an orographically lift situation where moisture will stack up against the mountains and produce a higher rainfall situation. It will be a series of low's swinging in..So the ground will increasingly get more saturated each time.. This will be a long duration rain event through the weekend..while 1 shortwave is stronger then the next. As we know ..This Elnino year has a ton of juice..so a 6-9" rain prediction for the entire event is NOT out of the question. I don't think we will see a 6" rainfall from 1 shortwave though. probably 3 storms with a 1-3" rainfall with each..until the upper low out west either occludes and dissipates..or moves east
whats your thinkin for ne

That QPF map isn't in complete range for PHL. PHL will actually get 4"+ instead of 2.5" on the 12z GFS.
12z GFS QPF for the PHL area:

Combined with snowmelt and the water in the ground, a stalling low is not on the list for welcome sights! Even in Indiana with some light rains and snowmelts, our local rivers are coming upwards in depth and in some cases, swift currents.
