Area Forecast Discussion
National Weather Service Melbourne FL
341 PM EDT SUN AUG 7 2016

.DISCUSSION...
Tonight...Vis imagery this afternoon shows a surface low swirling
over the I-10 corridor east of Lake City. The feature is forecast
to drift slowly northwest into Monday and become absorbed into a
broader area of low pressure centered over the GA/Al state line.
Abundant moisture in place and supplemented by moderate SW flow
areawide will continue to favor development of precipitation, most
notably during the daytime hours with surface heating coming into
play. For the remainder of the evening scattered showers and
storms will continue through dusk with a lowering of coverage
this evening with loss of sfc heating. Will maintain the
possibility of an isolated shower area wide overnight with main
chc of thunder over the gulf stream overnight and into early
Monday.

Mon-Tue...(from prev disc) Gradual weakening of the area of low
pressure over the Southeast wl occur late Mon into Tue night as
this area drifts slowly further north and northwest. High PWAT
values in excess of 2 inches, highest near and northwest of the
I-4 corridor. Will keep cloud cover and precipitation chances
above normal through much of the period. Slightly greater than
normal chance to likely POPs (50-60 percent) for the afternoons/early
evenings and generally ISOLD to SCT chances in between for precipitation.
Relatively warm temperatures continue aloft, but will have occasional
mid-level impulses moving through the area to aid convective
development.

The ECSB will either remain pinned along the east coast or not
develop on Mon, greatest chances for formation along the Treasure
Coast. On Tue...the surface flow will be weaker with development
likely from at least the Cape southward and even decent inland
movement across the Treasure Coast. Main concerns with showers/storms
continue to be locally heavy rain/lightning, though a few stronger
storms with locally gusty winds will also be possible, especially
where outflows meet the ECSB late in the day.

Wed-Sat...Deep layer Atlantic ridging builds back westward across
the region through the end of the week and into the start of the
weekend. We will return to the daily east/west coast sea breeze
regime. Southwesterly storm motion continues on Wed but weakens Thu-
Sat, becoming fairly light and eventually south to southeasterly as
the overall wind field weakens. With a gradual decrease in deep
layer moisture over ECFL as a whole, POPs will return toward
seasonal averages, while the interior and northern CWA will be
favored for highest pcpn chances. Max temps should average out at
least a few degrees higher than the previous days given the lower
coverage of diurnal clouds/convection. Overnight lows continue mild
and generally in the L-M 70s.

&&

.AVIATION...
Scattered evening SHRA and isolated TSRA will move NE and offshore
from the land area through 08/02Z. Brief MVFR conds possible in
affected locations mainly through 08/00Z. SW boundary layer/steering
flow overnight...may bring isolated SHRA through the overnight
hours...especially north of KISM/KMLB. SCT/NMRS SHRA and isolated
TSRA expected Mon...mainly after 16Z.

&&

.MARINE...
Tonight...Gradient winds ascd with low pressure over N FL wl bring
slightly higher SW winds to the open waters with fetch protected
conditions near the coast. Winds of 10 to 15 kts early should
abate by early Mon as the low starts to pull away from the area.

Mon-Thu...(prev disc) Unsettled weather conditions continue over
the region early in the period with influence from an upper
disturbance across the area and eastern Gulf. This pattern will
slowly weaken and move away from ECFL Wed-Thu. In return, deep
layer Atlantic ridging will build back westward across the area. A
general light/moderate SSW/S flow for surface winds Mon-Mon night,
then winds veer a bit more S/SSE Tue aftn, and finally southeast
Wed-Thu. Seas 2-3 ft near shore and 3-4 ft generally over the
offshore waters. Generally deeper moisture across the area will
keep an enhanced threat for convection over the coastal waters
Mon-Tue and a general decline in overall coverage Wed-Thu. The
threat for offshore moving storms will exist Mon-Tue and generally
north of the Cape for Wed before a general lighter wind pattern
aloft on Thu.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
A MOIST SOUTHWEST FLOW OF AIR ASSOCIATED WITH LOW PRESSURE NEAR
CEDAR KEY THIS MORNING WILL CONTINUE ACROSS EAST CENTRAL FLORIDA
TODAY WITH SCATTERED SHOWERS AND LIGHTNING STORMS ACROSS THE AREA.
SHOWERS ARE ALREADY PUSHING INTO LAKE COUNTY THIS MORNING, SO WE
CAN EXPECT AN EARLIER START TO STORMS LATER THIS MORNING, WITH
REDEVELOPMENT OCCURRING THROUGHOUT THE AFTERNOON.

TODAY'S STORMS WILL MOVE NORTHEAST AT NEAR 20 MPH, AND WILL HAVE
THE POTENTIAL TO PRODUCE FREQUENT LIGHTNING, TORRENTIAL RAINFALL
OF 1 TO 3 INCHES IN A 60 TO 90 MINUTE PERIOD, AND WIND GUSTS OF
35 TO 45 MPH. MOVE INDOORS TO SAFETY AT THE FIRST SIGN OF
THREATENING WEATHER.

.MARINE THUNDERSTORM GUST IMPACT...
A FEW OF THE STRONGER STORMS TODAY COULD PRODUCE WIND GUST UP TO
AROUND 35 KNOTS OVER INLAND LAKES AS WELL AS THE INTRACOASTAL AND
NEAR SHORE ATLANTIC WATERS DURING THE AFTERNOON AND EARLY EVENING.

.RIP CURRENT IMPACT...
WEATHER AND OCEAN CONDITIONS WILL PRODUCE A MODERATE RISK FOR
DANGEROUS RIP CURRENTS IN THE SURF ZONE TODAY. THE THREAT WILL BE
THE HIGHEST FROM 300 PM THROUGH SUNSET DUE TO TIDAL EFFECTS. TO REDUCE YOUR
RISK OF BECOMING CAUGHT IN A RIP CURRENT, SWIM ONLY WITHIN SIGHT
OF A LIFEGUARD, AND NEVER SWIM ALONE. CHECK WITH THE BEACH PATROL
FOR ADDITIONAL INFORMATION ABOUT OCEAN HAZARDS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
ABUNDANT MOISTURE WILL LEAD TO NUMEROUS AFTERNOON SHOWERS AND
THUNDERSTORMS THROUGH TUESDAY, WITH STORM COVERAGE RETURNING .
TO MORE SEASONAL LEVELS FROM MID TO LATE WEEK. SOUTHWEST STEERING
WINDS WILL ALLOW SOME OF THE AFTERNOON STORMS TO PUSH OFF THE
MAINLAND INTO THE INTRACOASTAL AND NEARSHORE WATERS. LOCALLY HEAVY
DOWNPOURS, OCCASIONAL TO FREQUENT LIGHTNING STRIKES, AND LOCALLY
GUSTY WINDS WILL BE THE MAIN HAZARDS IN STRONGER STORMS.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
