905 PM EST MON JAN 26 2015

.UPDATE...
THIS EVENINGS SOUNDINGS REFLECTS THE DRIER COOLER AIR SHOWING ON WV
IMAGERY WITH PW AT 0.43 INCH. SOME STRATO CU CLOUDS FORMED FROM THE
COOL AIR OVER THE RELATIVELY WARM GULF WATERS ARE INTRUDING INTO
COASTAL AREAS. THE FORECAST APPEARS ON TRACK WITH TEMPERATURES IN
THE 40S OVER NORTHERN FORECAST AREA TO 50S CENTRAL AND SOUTH UNDER
WEST TO NORTHWEST WINDS. THE LAKE WIND ADVISORY EXPIRED AS WINDS
OVER LAND AREAS TAPERED OFF THIS EVENING. SMALL CRAFT ADVISORIES ARE
IN PLACE OVER THE GULF WATERS IWTH HIGH SURF AND RIP CURRENTS
EXPECTED. NO CHANGES ARE PLANNED AT THIS TIME.

.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.
