AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
249 PM EDT SUN MAY 10 2015

.DISCUSSION...

SURFACE EASTERLY WINDS SHOULD FOCUS TODAY'S CONVECTION MOSTLY ACROSS
THE INTERIOR AND WEST COAST THIS AFTERNOON. THE MOST IMPRESSIVE
FEATURE OF TODAY'S SET UP ARE THE H85-H7 LAPSE RATES NEAR 7C/KM.
ALTHOUGH MIDLEVEL MOISTURE IS SOMEWHAT LACKING, THAT DIDN'T PREVENT
STORMS FROM FORMING OVER THE PAST FEW DAYS. A FEW STORMS COULD BE
SEVERE, WITH GUSTY WINDS AND HAIL THE MAIN THREAT, ESPECIALLY WITH
A LOWER FREEZING LEVEL TODAY. AS ANA AND ITS REMNANTS ARE FORCED
INTO THE MID ATLANTIC, AND SURFACE HIGH PRESSURE STRETCHES FROM
THE WESTERN ATLANTIC INTO THE SOUTHEASTERN STATES, EASTERLY FLOW
WILL BECOME DEEPER AND PWATS WILL RISE INTO EARLY NEXT WEEK. UPPER
TROUGH MOVING INTO THE GREAT LAKES, AND SURFACE LOW MOVING INTO
NEW ENGLAND LATER TUESDAY, WILL EVENTUALLY PUSH A FRONT INTO THE
PANHANDLE OF FLORIDA. HOWEVER THE BOUNDARY WILL STALL AS AN UPPER
HIGH CLOSES OFF OVER THE GULF OF MEXICO, AS THE UPPER PATTERN
BECOMES MORE AMPLIFIED. THIS PATTERN WILL PERSIST THROUGH MUCH OF
NEXT WEEK, WITH STORMS MORE NUMEROUS OVER THE INTERIOR AND WEST.
HOWEVER, WITH DEEPER MOISTURE BY TUESDAY ALONG THE EAST COAST,
COASTAL SHOWERS AND MORNING THUNDERSTORMS MAY BECOME MORE
POSSIBLE. HIGH PRESSURE MOVING TO THE EAST COAST BY THURSDAY, MAY
PROVIDE SLIGHTLY DRIER AIR, SUCH THAT SHOWERS AND STORMS MAY NOT
BE AS NUMEROUS HEADING INTO THE END OF THE WORK WEEK.

&&

.AVIATION...

CONVECTION THIS AFTERNOON IS STILL EXPECTED TO BE MAINLY INTERIOR
AND WEST. THE ONLY TERMINAL ASSIGNED VCTS IS KAPF AT 19Z. STRONG
THUNDERSTORMS ARE POSSIBLE THIS AFTERNOON/EARLY EVENING WITH AN
ISOLATED SEVERE THUNDERSTORM POSSIBLE WITH A CHANCE OF HAIL AND 50
TO 60 MPH WINDS. BRIEF PERIODS OF IFR CONDITIONS POSSIBLE WITH
OCCURRENCE OF SHOWERS/THUNDERSTORMS.

&&

.MARINE...

PERSISTENT SURFACE HIGH PRESSURE STRETCHING FROM THE WESTERN
ATLANTIC INTO THE REGIONAL WATERS WILL KEEP EASTERLY WINDS INTACT
OVER THE NEXT SEVERAL DAYS. WINDS MAY BE ABOVE 15 KTS AT TIMES
ACROSS THE ATLANTIC WATERS TONIGHT. WITH MOISTURE INCREASING,
NIGHT AND EARLY MORNING SHOWERS AND STORMS WILL BECOME MORE
NUMEROUS EARLY NEXT WEEK ACROSS THE ATLANTIC WATERS. STORMS WILL
BE MOST PROBABLE LATE AFTERNOON AND EARLY EVENING ACROSS THE GULF
WATERS. A FRONT WILL STALL NORTH OF THE GULF AND ATLANTIC WATERS
INTO THE MIDDLE OF NEXT WEEK.
