This sort of has the look of a storm that in the wintertime would have CT folks worried as that dry slot is racing east...while mid level deformation occurs from central NY (already at almost 1" of rain in the past 6 hours) through the Berks/SVT/SNH.

Some of those north GFS runs don't look that bad given where the current precip shields are setting up and the track of the dry slot.

agree...we could done with the worst of it here...looks pretty dry for now to the west.  Would be funny if we ended up with .50 after the models showing anywhere from 2-5 inches for the past few days

Radar really looks like the heaviest will be from I-90 and north due to the west-east banding....which some of those south model runs of the NAM won't even be close to correct.

Radar is doing a SWFE type deal in CT...burst then dry slot. It's actually a good thing as the heaviest rains with this will be further north than the heaviest 3-5" amounts the other day.

8 of the 14 June's I've measured have been 6.33" or higher! June is a wet month

 

I was noticing that.  There's normal months but a lot of 5-7" months in the record as well.  I have only one really dry one.

 

How much you at MTD? I'm up over 7.50 now

 

6.52" here.  I think you had some thunderstorms that I didn't have.  Either way it's been a wet month.

I have been watching the radar returns from ALB and it is fascinating to watch the northern edge of the shield of rain utterly halted for any addition NE displacement.   Just stuck there.   

 

Meanwhile, NYC may actually clear this afternoon, when looping hi res imagery.  

 

Water vapor imagery nicely shows the v-max in central NY state, slowly trundling eastward.  I think that the band of rain will sort of stall west to east very near where it is now, while the bottom edge near NYC rockets east during the afternoon.   This is just going by now-cast obs.  Thoughts?    I dunno, but it doesn't seem any model really aligns very well with current sat/rad trends, but I may be missing something.

Yeah I think that band will sort of stall where it is too as the low moves se and south of NYC. That will help establish additional isentropic lift an sort of redevelop rains in the Dryslot.

.NEAR TERM /UNTIL NOON TODAY/...

10 AM UPDATE...

00Z ECMWF APPEARS TO BE VERIFYING BEST WHEN COMPARED TO RECENT
OBSERVATIONS/RADAR AND SATELLITE TRENDS. THUS NOT MUCH CHANGE TO
PREVIOUS FORECAST. MCS MOVING ACROSS PA AND NJ WILL TRANSITION
INTO A BAROCLINIC WAVE/CYCLOGENESIS SOUTH OF LONG ISLAND THIS
AFTERNOON. ALREADY SEEING MODEST PRES FALLS OFF THE NJ COAST.
ASSOCIATED RAIN SHIELD MOVING RAPIDLY ACROSS THE REGION FROM WEST
TO EAST. DEW POINT DEPRESSIONS ARE NOT VERY LARGE SO NOT EXPECTING
RAIN TO EVAPORATE. INSTEAD RAIN SHOULD MOVE RAPIDLY EASTWARD
ACROSS THE AREA. HEAVIEST RAIN STILL EXPECTED AFTER 4/5PM AS LOW
LEVEL JET SETS UP JUST OFF THE SOUTH COAST WITH BEST MOISTURE
ADVECTION AND CONVERGENCE ACROSS EASTERN CT/RI AND SOUTHEAST MA.
AS A RESULT HEAVIEST LATER TODAY SHOULD BE FOCUSED FROM WESTERN MA
INTO CT/RI AND SOUTHEAST MA.

AS THIS LOW LEVEL JET SETS UP EXPECT EAST WINDS TO INCREASE LATE
TODAY ACROSS RI AND SOUTHEAST MA...YIELDING A WIND DRIVEN RAIN.
LATE DAY COMMUTE WILL BE SLOWED DOWN BY THIS ACROSS THIS REGION.
CHANCE OF ELEVATED CONVECTION AFTER 21Z/5PM ACROSS CT/RI AND
SOUTHEAST MA AS NOSE OF DRY SLOT APPROACHES THIS REGION...WITH
THETA-E DECREASING WITH HEIGHT. THIS WILL INCREASE THE RISK OF
ENHANCING THE RAINFALL OVER THIS AREA.

WILD CARD TO THIS FORECAST WILL BE NORTH-NORTHEASTWARD EXTENT OF
HEAVY RAINFALL. SHORT WAVELENGTH PATTERN IN PLACE WITH SLOW
DEPARTING MID LEVEL LOW OVER ATLANTIC CANADA PROVIDING CONFLUENT
MID LEVEL FLOW/SUBSIDENCE OVER NORTHERN NEW ENGLAND. THIS WILL
YIELD A SHARP QPF GRADIENT. THUS HIGHEST CONFIDENCE FOR HEAVY
RAINFALL IS ACROSS WESTERN MA-CT-RI AND SOUTHEAST MA. LOWEST
CONFIDENCE IS ACROSS NORTHEAST MA INTO SOUTHERN NH WHERE MUCH LESS
RAINFALL IS POSSIBLE.

AS PREVIOUS SHIFT MENTIONED ONCE RAIN BEGINS TEMPS WILL FALL INTO
THE 50S.

maybe some of the precip redeveloping in PA will get you.

 

is that you with your sister eating chinese food?

those light showers could have been a complex of storms if that MCS this morning hadn't crapped up the airmass over PA

those are my children

You wonder if the dry slot ever fills back in. You could envision it not and just left with drizzle/ light showers of misery

Sure looks like it might be done....maybe some light showers later with that stuff in North Central PA?  Damage is done, everything wet again but we have dodged a serious bullet....2 inches of rain would have been a problem let alone 3 or 4.
