.NEAR TERM /THROUGH SATURDAY/...

-- Changed Discussion --

gradually thinning. There may be some patchy fog in the favored
locations with light winds and falling temperatures, however

the 50s and 60s.

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
Warm and dry conditions will persist through the weekend under
continued ridging. Saturday should see mostly sunny skies with a few
high cirrus, with highs once again in the mid 80s. Lows Saturday
night in the 50s/60s, with patchy fog possible again.

Sunday will be even warmer under mostly sunny skies. 925 mb
temperatures of 22-24C should allow highs to reach the upper 80s,
with a few spot 90F readings possible as well. Mild conditions
Sunday night with lows only in the 60s/70s.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
High pressure at the surface and aloft will allow for dry
conditions over the region Monday and part of Tuesday. At the
same time Hurricane Maria will be moving north over the west
Atlantic Ocean Monday into Wednesday night or Thursday.
At this moment it is not expected that it will affect our area,
however it is possible we could get some external rainbands
Tuesday or Wednesday if it gets close enough. Please monitor
the National Hurricane Center`s website hurricanes.gov for more
information.

A cold front will move through our CWA either Wednesday night or
Thursday increasing the chance of showers over our area and pushing
Maria away from the US east coast. Dry conditions return behind it
later on Thursday and Friday.

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
Scattered to broken deck of high clouds expected through
tonight. Some patchy fog possible each night and early morning
(mainly CHO/MRB), otherwise, mainly VFR through the weekend.

VFR conditions expected Monday and Tuesday with high pressure
over our area. Some sub-VFR conditions possible later Tuesday
and Wednesday with maybe some showers around, but looking mostly
dry.

.MARINE...
High pressure will allow for light winds around 10 knots or less
through the weekend.

No Small Craft Advisories expected between Monday and Tuesday
as wind gusts will be below criteria over our area. Wind gusts
increase Tuesday night and Wednesday with Hurricane Maria over
the west Atlantic Ocean.

&&

tonight`s high tide cycles at Annapolis (Anne Arundel) and
