- Heat and humidity return by midweek.

.DISCUSSION...
KEY MESSAGE 1...Dry and seasonable weather with low humidity levels 
this weekend into Monday.

Areas of patchy fog from lingering moisture quickly mix out this 
morning as surface high pressure builds over the region and becomes 
centered over New England Sunday into Monday. A more comfortable 
airmass under this feature brings temperatures in the mid 80s and 
low humidity with dew points in the upper 50s/low 60s. The drier air 
mass will keep rain chances to near zero before moisture returns 
later in the week. A disturbance sliding well to the S of the region 
may provide a few high clouds across the S coast later Saturday, but 
impacts from weather will be very limited this weekend. 

KEY MESSAGE 2...Heat and humidity return by midweek. 

Mid-level high pressure ridging will remain over the Central U.S., 
stretching across into the Mid Atlantic through much of next week, 
bringing mostly hot and dry weather across the Northeast. Hot 
temperatures in the low to mid 90s will return mid week with 850mb 
temperatures ranging from +18 to +22C. We may need to consider a 
period of heat headlines with dew points rising into the mid to 
upper 60s again.

Rain chances through the period will generally remain low with a 
better chance on Tuesday into Wednesday with a possible shortwave 
trough moving through Northern New England. Southerly return flow at 
the surface will be short lived prior to this perturbation moving 
through, so moisture depth will remain shallow. Models are showing 
possible deeper upper-level troughing toward the end of the week, so 
we may start to see increasing rain chances and slightly cooler 
temperatures if that trend continues.
