  next period of rain arriving as early as Friday afternoon.

.DISCUSSION...
KEY MESSAGE 1...Warm and more humid today with isolated showers and 
thunderstorms possible in the afternoon, mainly across south coast 
and southeast MA.

For today, surface high pressure will be positioned to the south of 
the region while our next system and cold front approach from the 
west. This will advect in more moisture at the surface along with 
weak warm advection bringing up 925mb temperatures a degree or two. 
This will support high temperatures in the mid to upper 80s with 
southwest to westerly winds. Dewpoints rise into the low 60s, making 
it feel a touch humid. 

The added heat and moisture ahead of the approaching front will 
build marginal instability through the day (MLCAPE 200-500 J/kg). 
This is enough to support thunderstorms as long as the cold front 
does not come in too quickly (before instability builds up enough). 
The moisture is fairly limited, especially evident in the mid-levels 
which will favor more isolated to scattered showers or thunderstorms 
this afternoon. 0-6 km bulk shear values range 25-35 kts to support 
organized convection if it develops. However, the weaker mid-level 
lapse rates may act to suppress thunderstorm development and 
longevity.


The 00Z high-resolution guidance has stayed split on potential for 
showers and thunderstorms. The NAMnest/FV3, and RRFS show 
isolated showers and storms developing across the southern 
portion of the region, mainly across the south coast. The ARW 
remains dry. The HRRR is mainly dry, with an isolated shower or 
two. This supports the lower probability (< 30%) for isolated 
showers or thunderstorms in the afternoon. Highest chances for
showers/storms will be in the 2-7 PM timeframe near the south 
coast into southeast MA. The cold front fully pushes through by 
tomorrow night diminishing any lingering showers. 

KEY MESSAGE 2...Trending cooler late-week. Scattered showers 
possible Thursday with next period of rain arriving as early as 
Friday afternoon. 

A cooler post-frontal airmass will be in place Thursday and Friday 
which will bring temperatures closer to normal in the upper 60s near 
the coast and low-mid 70s further inland/valleys. A shortwave trough 
drops southward across the region on Thursday which may bring a 
period of scattered light showers.

Confidence in the upper level pattern decreases Friday, mainly with 
regards to the speed and evolution of a cutoff low that tracks south 
from Canada. The GFS and AI GFS remain the quicker solutions, 
bringing the system in quicker with rain arriving as early as mid-
afternoon Friday. Remaining deterministic guidance has the low and 
accompanying rain arriving in the late Friday night-early Saturday 
AM timeframe. Despite the different timing in the deterministic GFS, 
the GEFS shows the highest probabilities for rain overnight Friday-
Saturday with more moderate values for Friday. There is a little 
more confidence in the widespread rain arriving late Friday night; 
however, a few showers are possible Friday at this time. 

KEY MESSAGE 3...Becoming unsettled by the weekend with below normal 
temperatures and periodic rain chances through early next week.

Previously noted, there are timing differences for the cutoff low 
amongst guidance that will dictate the timeframe of the greater 
shower/rain chances over the weekend. A quicker arrival of the 
system could taper off the more widespread showers Saturday 
afternoon. Regardless of the timing, Saturday will be unsettled with 
at least scattered showers for the first half of the day if not a 
large portion of the day. Sunday will be the drier day. The cutoff 
low will bring in a cold pool aloft southward into the region 
favoring below normal temperatures for Saturday in the 60s and 
closer to seasonable for Sunday. The pattern stays fairly steady 
through early next week due to a blocky pattern aloft. This will 
keep a troughy pattern over the region keeping temperatures 
seasonably cool. A few embedded shortwaves move through the flow 
bringing a period or two of scattered showers with a greater chance 
on Monday.
