    You have absolutely no idea what you’re talking about. Please stop. The subsurface just under regions 1+2 and 3 is over +6C. You have been saying these regions are going to fall apart since the end of March and posting the wretched CFS over and over. 5 months in a row now. Give it up. You’re wishcasting

    It’s gonna be OK maybe one of your predictions will come to fruition

    Excessive Rainfall Discussion
    NWS Weather Prediction Center College Park MD
    353 PM EDT Sat Jul 08 2023
     
    Day 2
    Valid 12Z Sun Jul 09 2023 - 12Z Mon Jul 10 2023 
    
    ...THERE IS A MODERATE RISK OF EXCESSIVE RAINFALL FOR PORTIONS OF 
    THE MID-ATLANTIC INTO WESTERN NEW ENGLAND...
    
    ...20Z Update...
    
    ...Mid-Atlantic through New England...
    
    In coordination with all the forecast offices from DC/Baltimore 
    north through New England, a Moderate Risk area was introduced 
    with this afternoon's update for portions of the Mid-Atlantic into 
    western New England. All guidance continues to hone in on a 
    corridor of heavy rainfall caused by numerous training showers and 
    thunderstorms developing across the Moderate Risk area Sunday 
    afternoon for southern and western areas, then progressing through 
    New England Sunday Night. Expect a widespread 2-4 inch event 
    especially from eastern PA north through VT. However local amounts 
    are likely to exceed 6 inches of rain, with the most likely areas 
    for the higher rainfall totals through the Catskills/Poconos of 
    NY/PA and also through the Green Mountains of VT. Much of this 
    area has been very hard hit in recent days with heavy rainfall, 
    with a large area over 300% of climatological normal rains per 
    2-week AHPS data. Adding a stalling front into the mix which will 
    allow for training of abnormally high moisture air on the order of 
    PWATs to 1.75 inches makes for a likely scenario for flash 
    flooding, especially when adding terrain influences into the mix.
    
    With the full day's worth of HREF data first available at 12Z, 
    it's notable that portions of east central VT have a 30% chance of 
    exceeding 100-year annual return intervals for the amount of rain 
    expected, with the Catskills/Poconos and Green Mountains all over 
    70% chance of exceeding 3 and 6 hour FFGs Sunday afternoon and 
    evening. The steady signal of widespread rain and good model 
    agreement on both timing and areal amounts added enough confidence 
    to the forecast to upgrade to the Moderate Risk for this update.
