Yeah/ GFS def has drier air working into SNE for much of tomorrow. A brief reprieve. BOX doesn't seem to buy it beyond that
Wednesday
A brief period of dry weather for southern New England on Wednesday
as a relatively dry air mass characterized by PWATs ranging from 1
to 1.25 inches which is relatively low for mid-July. This will
support abundant sunshine across southern New England on Wednesday
with the exception of some diurnal cu. 925 hPa temps near 25 Celsius
will support hot temperatures in the low 90s at the surface. With
dewpoints only in the mid to upper 60s, the heat index will only be
a degree or two higher on Wednesday afternoon. Wednesday definitely
looks to be the pick of the week for those who prefer sunshine.
