Pour l'instant il manquerait quelques ingrédients pour des orages costauds Mardi en après-midi mais l'essentiel y serait. Le SPC pourrait même "upgrader" en "slight risk" dans ses prévisions futures. Ça reste à suivre..
.Parts of the Northeast/New England...
Midlevel lapse rates will be weak, but relatively strong heating
will support moderate buoyancy by afternoon across parts of the
Northeast, along and ahead of the cold front. Stronger ascent and
deep-layer flow will remain north of the front, but sufficient flow
and steepening of low-level lapse rates will support a threat of
damaging gusts with any strong storms across the region. Storm
coverage is uncertain, but greater severe probabilities may
eventually be needed if trends support more than isolated storm
development during the afternoon and evening.
