LONG TERM /Wednesday Night through Monday/...
The long term period starts with high pressure aloft building
into the area through the end of the week, then shifting east off
the coast. At the surface, the cooler and drier airmass that has
been dominating the short term will remain in place through much
of the weekend keeping high temps in the 70s and lows in the 40s
and 50s through the first half of the extended.

Moisture quickly returns to the area by late weekend/early next
week as a cold front starts to approach the area. Models have come
into better agreement with pushing a deep longwave trough towards
the eastern US and bringing a closed low from Mississippi/Alabama
to the area on Monday. It is quickly ushered through and out of
the area by Tuesday as the cold front sweeps through. The ECMWF is
only slightly slower and wetter, compared to the GFS. Went with
chance pops from late weekend through early next week with highest
pops on Monday, highs in the 70s and 80s, and lows in the 50s and
60s.
