.WHAT HAS CHANGED...

.KEY MESSAGES...
- Dry conditions and comfortable summer temperatures continue
through the start of the work week.
- Heat and humidity return midweek with possible heat headlines
Tuesday and Wednesday.

.DISCUSSION...
KEY MESSAGE 1...Dry conditions and comfortable summer
temperatures continue through the start of the work week.
High pressure begins to build over the region and becomes centered
over New England later today, bringing a seasonable airmass into
place over the next several days. Temperatures in the low to mid 80s
and dewpoints in the upper 50s to low 60s will continue through the
start of the work week. The drier air mass will also keep rain
chances to near zero before moisture returns later in the week.
KEY MESSAGE 2...Heat and humidity return midweek with possible
heat headlines Tuesday and Wednesday.
Mid-level high pressure ridging will center over the Central
U.S., stretching 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
some locations possibly nearing 100 Tuesday and Wednesday. We
may need to consider a period of heat headlines with dew points
rising into the mid to upper 60s, which will produce heat
indices in the upper 90s for most of the interior portions of
the forecast area each afternoon.
Rain chances through the period will remain low with high
pressure being in control. Models continue to show an amplifying
upper-level trough toward the end of the week, which may bring
increasing rain chances and cooler temperatures if that trend
continues.
