AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
355 AM EST SAT JAN 24 2015

.SHORT TERM (TODAY-MONDAY)...
ZONAL MID/UPPER LEVEL FLOW THAT HAS BEEN DOMINATING SOUTH FLORIDA
THE PAST SEVERAL DAYS WILL BE RAPIDLY CHANGING THIS MORNING AS A
LARGE SCALE CYCLONIC CIRCULATION DEVELOPS OVER NORTH AMERICA. THE
FIRST IN A SERIES OF COLD FRONTS IS CURRENTLY EXTENDING FROM NORTH
FLORIDA INTO THE EASTERN GULF OF MEXICO AND WILL BE APPROACHING LAKE
OKEECHOBEE AND THE SOUTHWEST COAST BY 12Z AND RAPIDLY PUSH ACROSS
SOUTH FLORIDA AND OFF THE SOUTHEAST COAST SHORTLY AFTER 18Z. A NEAR
SOLID BAND OF SHOWERS AND THUNDERSTORMS EXTENDS ALONG THE FRONT AND
THIS WILL SHIFT EAST WITH THE FRONT DURING THE EARLY MORNING GIVING
MOST LOCATIONS OVER SOUTH FLORIDA A BRIEF SHOT OF RAINFALL. THE
CONVECTIVE IS MOVING ACROSS THE WARM WATERS OF THE GULF AND THIS
HAS FIRED OFF QUITE OF BIT OF LIGHTNING ACTIVITY AS THE LINE
APPROACHES THE SOUTHWEST COAST. DECENT AMOUNT OF VERTICAL SHEAR
EXISTS TO KEEP THIS LINE ACTIVE AND AS IT ENTERS THE GULF COASTAL
WATERS THERE COULD BE ONE OR TWO WATERSPOUTS OCCUR. THE LINE
SHOULD BEGIN TO WEAKEN AS IT APPROACHES THE MAINLAND DUE TO THE
COOLER SURFACE TEMPERATURES SO THE STRONGER THREAT OF STORMS
SHOULD REMAIN OFFSHORE. RAINFALL AMOUNTS WILL GENERALLY BE
LIMITED TO LESS THAN ONE-HALF INCH DUE TO THE NARROW OPPORTUNITY
OF A CONVECTIVE BAND AND ITS BRIEF NATURE. HIGH PRESSURE WILL
BUILD BEHIND THE FRONT WITH ANOTHER REINFORCING COLD FRONT MOVING
THROUGH SOUTH FLORIDA EARLY MONDAY. THIS WILL BE A DRY FRONT AS
THE FLOW REMAINS NORTHWESTERLY AND RETURN MOISTURE WILL THEREFORE
BE LIMITED.

.LONG TERM (TUESDAY-FRIDAY)...
UPPER FLOW WILL CONTINUE OUT OF THE NORTHWEST THROUGH WEDNESDAY WITH
A NORTH SURFACE FLOW SO COOL TEMPERATURES WILL ALSO DOMINATE SOUTH
FLORIDA THE FIRST PORTION OF THE EXTENDED PERIOD. A RETURN TO A
ZONAL FLOW PATTERN WILL RESUME TOWARDS THE END OF THE WEEK WITH
SURFACE HIGH PRESSURE SHIFTING EAST INTO THE ATLANTIC. THIS WILL
RESULT IN A SLOW MODIFICATION OF THE AIRMASS WITH A RETURN FLOW OUT
OF THE EAST.

.MARINE...
WIND AND SEAS WILL RAPIDLY DETERIORATE THIS MORNING AS A SOUTHWEST
WIND AHEAD OF THE FRONT INCREASES TO 20-25 KNOTS OVER THE ATLANTIC
AND THEN SHIFTS TO THE NORTHWEST BEHIND THE FRONT. SEAS WILL BUILD
TO 6-8 FEET OVER BOTH THE GULF AND ATLANTIC WATERS THIS AFTERNOON
INTO EARLY TONIGHT SO A SCA HAS BEEN ISSUED FOR THESE AREAS. A
SCEC STATEMENT WILL EXIST FOR LAKE OKEECHOBEE AND BISCAYNE BAY.
WIND AND SEAS WILL BEGIN TO SUBSIDE LATE TONIGHT AS THE PRESSURE
GRADIENT SLACKENS, HOWEVER THE FLOW WILL REMAIN OUT OF THE
NORTHWEST TO NORTH THROUGH EARLY NEXT WEEK AS HIGH PRESSURE
CONTINUES ACROSS THE SOUTHEAST STATES BEFORE THE HIGH SHIFTS EAST
ON WEDNESDAY INTO THE ATLANTIC.
