We get our brief warm up followed by about a week of easterly flow. Rainfall amounts will probably be determined in the short term. Looks like models are struggling with the placement of a PRE. Often happens with a subtropical or tropical systems to our SE.

Should get the rest of the spotty rain to pass through before noon and clear things up for the warmest day of the year so far for many along with the first 80s for some places who missed it on My 3rd.

 

5/17 - 5/22 very unsettled with cutoff meandering along in the east.  Perhaps sneaking in a nice day.  Summer looks to arrive in time for Memorial day weekend with perhaps some consecutive warm to hot days and the seasons first 90s.

While plenty of uncertainty still exists with regard to next week my hunch says we will end up being much drier then what the models were originally showing. We'll see.

Looks like my thoughts on the models going drier for next week may wind up be wrong. The overnight Euro was pretty wet and like you mentioned we will have to see how a PRE sets up for early next week.

It'll be interesting to track the ULL next week with the TS off the coast.  Mid Atlantic is a good bet for the heaviest but we'e not far off.  Wouldnt surprise me to sneak in a nice day (maybe Wed).  Looks like the ridging finally establishes itself on/around 5/23 in time for a warm Memorial Day as it looks now.

Clear skies to your north up in Orange County 64/60. Point and click forecast has a high of 84 up this way.

SPC shifted the enhanced risk area to the northwest and put our area in the slight risk Category.

SPC AC 151255

   Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0755 AM CDT Fri May 15 2020

   Valid 151300Z - 161200Z

 

Northeast States...
   Overall change from the 06Z outlook is minimal with concerns over
   the amplitude of boundary-layer moistening depicted in latest
   guidance.

   A shortwave trough over Lake Superior will translate east into Maine
   by early Saturday. Attendant mid-level speed max is progged to
   amplify with 500-mb flow in excess of 50 kt overspreading much of NY
   and northern New England by peak heating. Surface cyclone should
   diurnally deepen as it reaches the NY/VT border area around 21Z.
   Surface temperatures should warm through the 70s and low 80s south
   of the cyclone, ahead of an impinging cold front. While low-level
   moistening is underway, the bulk of guidance may be too aggressive
   with depiction of warm-sector dew points in the low 60s.
   Nevertheless, enlarged low-level hodographs should favor a few
   supercells developing from central NY and spreading towards southern
   VT/NH and western MA. Modest mid-level lapse rates will likely
   curtail significant severe potential.

There could be a very sharp cutoff between who gets the heaviest rains and doesn’t.

Euro and UKMET pretty much identical to the CanSIPS and JMA for the summer. Strongest heat over the Western US  with wet and humid conditions in the East. Also notice the heavy precipitation with the IO standing wave.

@bluewave

Will this summer be wetter then last summer. I mean June 19 had 5.46” and July 19 was 5.77”

Aug was a bit dryer at 3.70”

Itll be crazy if it’s wetter.

We know that the summer dew points increased to record levels since the super El Niño in 2016. But it will be interesting to see how those seasonal model forecasts work out for this summer.
