.KEY MESSAGES...

- Dry with cooler than normal temperatures today and tonight. 

- Seasonably warm temperatures return mid-week, continuing
  through Friday. A few showers possible sometime late Thursday
  into early Friday, otherwise mainly dry. 

- Potential for a shift to an unsettled pattern with chances 
  for rain for second half of weekend through early next week.

.DISCUSSION...
KEY MESSAGE 1...Dry with cooler than normal temperatures today
and tonight. 

Surface high pressure will be positioned the region today 
bringing dry conditions and mainly sunny skies. A cooler airmass
will be in place with 925mb temperatures several degrees cooler
than Monday. This will yield more "Fall-like" temperatures with
high temperatures in the upper 60s and low 70s. Locations along
the immediate east coast may even be cooler in the mid 60s as a 
result of the light easterly onshore flow. The high pressure 
center shifts offshore tonight shifting winds to the S then SW.

KEY MESSAGE 2...Seasonably warm temperatures return mid-week, 
continuing through Friday. A few showers possible sometime late 
Thursday into early Friday, otherwise mainly dry. 

A strong upper level ridge/high remains positioned across the 
southeast CONUS mid-week, subtly building into the northeast mid-
week. An upper trough in northern Canada will hold off any stronger 
ridging from building into the northeast, favoring a flatter/zonal 
pattern overall. This should support warmer temperatures advecting 
in within the SW flow. Highs Wednesday/Thursday rise back into the 
mid and upper 70s with 80s in the valleys (seasonably warm for mid-
Sept). Surface high pressure should support mainly dry conditions 
Wednesday and Thursday. 

Ensemble/deterministic guidance indicates potential for a weak 
shortwave trough to drop in from the northwest late Thursday into 
Friday. Ahead of this shortwave, a plume of anomalous moisture 
advects in from the west on Thursday. Across ensemble guidance,
the PWATs run around 170-200 percent of normal or more directly
put, PWATs 1.7-1.9". The anomalous moisture is being signal 
across NAEFS guidance as well. This building moisture will bring
a more humid day for Thursday. There is some spread across 
guidance with regards to the timing of the showers; however, 
there is general agreement of the highest chances falling in the
late Thu afternoon to early Fri morning timeframe. That 
timeframe should be able to be narrowed down as the details of 
the pattern become more clear as we go through the week. Despite
the anomalous moisture, the weaker lift with this wave and 
later timing has limited the potential for widespread heavy 
rain. Ensemble QPF remains below 0.50" for most areas. We'll 
have to keep an eye on some embedded heavier showers that could 
bring locally higher amounts. A drier airmass pushes in behind 
the exiting shortwave Friday bringing dry conditions dominating 
by the afternoon. A cooler airmass sinks across the region by 
Saturday bring a return of Fall-like temperatures. 

KEY MESSAGE 3...Potential for a shift to an unsettled pattern
with chances or rain for second half of weekend through early 
next week.

Ensemble guidance hints at a transition to a more unsettled pattern 
for the second half of the weekend and into early next week. A low 
pressure system tracks eastward from the Great Lakes bringing 
increased precipitation chances more likely in the Sun-Mon 
timeframe. There indications of another wave or two bringing 
periods of rain for early next week as well. Confidence in 
precipitation chances and timing should increase as we get 
closer.
