AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL
317 PM EST MON JAN 26 2015

.SHORT TERM (TONIGHT-TUESDAY)...
HIGH PRESSURE WILL REMAIN IN PLACE ACROSS THE AREA FOR TONIGHT
THROUGH TUESDAY AS THE UPPER TROUGH IN PLACE ALONG THE EASTERN US
COAST SHIFTS A BIT TO THE EAST. ANOTHER DRY REINFORCING FRONT WILL
BE APPROACHING THE AREA LATE IN THE PERIOD. WINDS WILL REMAIN
GENERALLY FROM THE W/NW THROUGH THE PERIOD WITH WIND SPEEDS
WEAKENING OVERNIGHT...AND INCREASING AGAIN TUESDAY AFTERNOON TO
10-15 MPH WITH SOME HIGHER GUSTS...BUT NOT AS STRONG AS TODAY. THE
CURRENT ADVISORIES ARE SET TO EXPIRE AS THE WINDS COME DOWN
OVERNIGHT. TEMPERATURES WILL BE IN THE UPPER 30S TO LOWER 40S
NORTH...TO THE LOWER 40S TO NEAR 50 CENTRAL...AND MID 40S TO LOWER
50S SOUTH. HIGHS TUESDAY WILL BE GENERALLY IN THE 60S...EXCEPT
AROUND 70 SOUTH.

.LONG TERM (TUESDAY NIGHT-MONDAY)...
STILL NO SIGNIFICANT CHANGES TO THE ONGOING LONG TERM FORECAST. THE
UPPER-LEVEL PATTERN FEATURES A LARGE RIDGE OUT WEST WITH A DEEP
UPPER TROUGH OVER THE EAST. FOR TUESDAY NIGHT INTO WEDNESDAY...A
CLOSED LOW PRESSURE AREA AT THE SURFACE WILL SHIFT AWAY FROM THE
NORTHEAST AS AN AREA OF HIGH PRESSURE BUILDS OVER THE EASTERN
SEABOARD BEHIND ANOTHER REINFORCING AND DRY COLD FRONT. THIS FRONTAL
PASSAGE WILL SERVE TO DROP OUR TEMPERATURES A FEW DEGREES FOR
WEDNESDAY AFTERNOON...WITH HIGHS FROM AROUND 60 TO THE MID AND UPPER
60S UNDER MOSTLY SUNNY SKIES. THE SURFACE HIGH WILL SHIFT INTO THE
WESTERN ATLANTIC FOR THURSDAY AS ANOTHER TROUGH AND SURFACE LOW MOVE
EASTWARD TOWARD THE NORTHEAST. THIS WILL DRAG ANOTHER COLD FRONT
THROUGH THE FORECAST AREA ON FRIDAY WITH NO RAIN CHANCES IN THE
FORECAST DUE TO LACK OF MOISTURE. SURFACE HIGH PRESSURE WILL AGAIN
BUILD NORTH OF THE REGION WHICH WILL LEAD TO A DRY DAY ON SATURDAY.
FOR SUNDAY INTO EARLY NEXT WEEK...MODELS SHOW A LOW PRESSURE AREA
DEVELOPING ALONG THE NORTHERN GULF COAST AND THEN MOVING
NORTHEAST...DRAGGING A COLD FRONT THROUGH THE FORECAST AREA IN THE
PROCESS. THIS ONE LOOKS LIKE IT WILL BRING A FEW SHOWERS WITH IT SO
WILL INTRODUCE A SLIGHT CHANCE IN THE FORECAST. TEMPERATURES FOR THE
END OF THE PERIOD WILL RUN RIGHT AROUND NORMAL VALUES.

&&

.AVIATION...
VFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD WITH THE BREEZY WNW
WINDS LIGHTENING AFTER SUNSET TO GENERALLY 8-11KTS. WINDS WILL
INCREASE AGAIN AFTER 27/15Z TO AROUND 11G20KTS.

&&

.MARINE...
WINDS WILL GRADUALLY SUBSIDE DURING THE OVERNIGHT HOURS HOWEVER SMALL
CRAFT CONDITIONS CAN BE EXPECTED THROUGH THE EVENING AND INTO
PORTIONS OF THE OVERNIGHT AS SEAS WILL BE SLOWER TO FALL BELOW
CRITICAL HEIGHTS. SCA WILL EXPIRE AT 03Z FOR TAMPA BAY AND CHARLOTTE
HARBOR...12Z FOR THE NEARSHORE WATERS AND 15Z FOR THE OFFSHORE
ZONES.

&&

.FIRE WEATHER...
