...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER...

.DISCUSSION...
Persistent springtime upper ridging continues to stretch from the
N Carib, over the FL Peninsula and up into the Eastern Seaboard 
with subsidence aloft to keep the warm and mainly dry conditions 
in place through the weekend. At lower levels breezy easterly 
flow continues around the strong high pressure center in the W 
Atlantic as a result of the tight pressure gradient. Have seen 
some light low topped sprinkles on radar in this flow as well but 
don't expect much in the way of measurable rain and will keep 
blind 10 PoPs mainly interior areas.

The upper ridge will finally get suppressed early-mid-week as a 
shortwave moves through the Deep South. Surface high pressure in
the W Atlantic weakens but will continue to dominate at the low 
levels keeping the area warm and dry while the sea breeze returns 
at least to coastal areas. Some models hinting at isolated
interior seabreeze showers Tuesday afternoon but will hold less
than 20 PoPs for now in those areas.

By late week, ridging becomes reestablished aloft to keep the
warm/dry sensible wx conditions in place.

.AVIATION...
(18Z TAFS)
VFR conditions continue with a combination of diurnal SCT lcl 
BKN050-060 cumulus clouds and cirrus aloft this afternoon with 
gusty easterly winds to continue through the evening surge then 
decrease overnight and clouds fade. Winds and clouds increase 
again Sun around 14Z. 

&&

.MARINE...
High pressure with a tight pressure gradient continues over the E
Gulf waters with winds around 20 kts and seas 4-7 ft to produce
hazardous SCA conditions through the evening surge and tonight. 
Brief decrease in E winds Sun morning before another afternoon/evening
increase with periods of SCEC/SCA likely into early next week. 
High pressure remains in the region as winds slightly decrease into
mid week with the afternoon sea breeze returning.

&&

.FIRE WEATHER...
Warm and dry springtime high pressure remains in the region with
daily minimum RH values at or just below critical levels each 
afternoon. Easterly winds become occasionally gusty each afternoon
into evening with high dispersions in some areas. Even though 
fuels remain just moist enough to preclude red flag warnings, an 
elevated fire weather risk remains with these conditions.
