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. && .PRELIMINARY POINT TEMPS/POPS...
