A 1024 MB HIGH IS CURRENTLY CENTERED OVER MICHIGAN WITH TROUGHING
WELL TO THE NORTH AND WEAK NORTHWESTERLY FLOW MOVING IN FROM THE
UPPER RIDGE OUT WEST. THE AFOREMENTIONED SURFACE HIGH WILL MOVE TO
OFF OF THE MID-ATLANTIC COAST EARLY TOMORROW. NEW SURFACE HIGH
PRESSURE WILL SHIFT DOWN FROM THE UPPER PLAINS THE LATTER PART OF
THE WEEK, KEEPING PRECIPITATION AT BAY FOR NOW.
TEMPERATURES WILL REMAIN ABOVE NORMAL WITH A GRADUAL WARMING TREND
EACH DAY. WHEN WE ROUND OUT THE WORK WEEK MID TO UPPER 80S ARE
FORECAST FROM THE CENTRAL TO SOUTHERN VALLEY. THE COOLEST MORNING OF
THE WEEK WILL BE THIS MORNING WHERE THE UPPER HALF OF OUR FORECAST
AREA WILL SEE LOWS IN THE 40S; 50S FOR LOWS FOR THE REMAINDER.
THOUGH THE AIR IS ON THE DRIER SIDE, FOG NEAR BODIES OF WATER IS
STILL POSSIBLE.
OUR NEXT CHANCE OF PRECIPITATION WILL ARRIVE SOMETIME THIS WEEKEND.
THERE ARE UNCERTAINTIES AS TO WHAT AND WHEN. AS OF LAST NIGHT, A
TROPICAL DISTURBANCE WITH A 80 PERCENT CHANCE OF DEVELOPMENT
DETERMINED BY THE NHC, WILL DRIFT TOWARDS THE CENTRAL NORTHERN GULF.
DETERMINISTIC MODELS HAVE GREAT DIFFERENCES IN WHAT THEY THINK WILL
OCCUR. IF ONE THING'S CERTAIN IS THAT OUR AREA WILL SEE RAIN LIFTING
UP FROM THE SOUTH SATURDAY AND POSSIBLY INTO MONDAY. SOME GUSTY
WINDS, MOST LIKELY FROM A STRONG PRESSURE GRADIENT, COULD BE
POSSIBLE AND OF COURSE WILL BE MONITORING.
