It's raining heavily in places in Northern and Central PA that were supposed to be dry currently.

 

Those areas on the Euro and HRRR were supposed to get heavy rains this morning.

 

But you can see how the northern edge of the line basically hits a wall when it tries to come

east so it's forced under.

We're talking about two different MCS systems. I don't know how else to explain it.

if you look at the loop he posted, the current MCS hits a wall in the next few hours and is shunted south.   The next one forms to the west of that and drops down to DCA area.

How can I trust a model that currently shows a severe warned MCS as a weak line of showers?

when that sucker hits a brick wall around Harrisburg, don't come cryin' to me.... :underthewx:

Maybe it ends up happening like that and maybe it doesn't. My point has been made. If the model doesn't show the MCS to begin with then I'm not sure how it could be correct.

So we've gone from potential LR above normal to two days of 90+ to one day to now no heat long term. Sigh.

 

going to  be some similarities to last summer in that the warmth is mid and late summer IMO.

Can't remember the last time that an advertised warm up around here didn't exceed expectations but came in more modest instead.

still 4 days away so it can always change especially if the cutoff is further east and/or weaker than progged.  GFS Was pretty weak with it.

12z Euro does a cyclonic loop with the LP offshore this weekend into Monday with

most of the rain staying to our south and east. A few showers back in over LI

but not much rain. A cooling onshore flow will prevail and the warm up

on Tuesday is less impressive than earlier runs. Could be some nice surf

per the Euro wave model with strong winds off the East Coast.

How does Saturday look down the shore? Cloudy and cool?

I'm allllll about that. Let's see what happens. Water temps are way cold compared to onshore temps due to all the upwelling. Has been keeping people out of the water which is fine with me.
