DISCUSSION
ISSUED AT 134 PM EST TUE MAR 3 2026
MOSTLY DRY CONDITIONS WITH A SIGNIFICANT WARMING TREND EXPECTED
THROUGH FRIDAY. THIS IS THE RESULT OF STRENGTHENING HIGH PRESSURE OFF
THE SOUTHEAST COAST.
PRECIPITATION CHANCES BEGIN TO INCREASE FRIDAY, AND ESPECIALLY INTO
THE WEEKEND, AS AN APPROACHING SYSTEM FLATTENS THE RIDGE. THE
FRONTAL BOUNDARY LOOKS LIKE IT MAY STALL ACROSS THE REGION
THROUGH TUESDAY, KEEPING CHANCES OF PRECIP IN PLACE. RECORD HIGH
TEMPS ARE CURRENTLY FORECAST ON SATURDAY BUT LESS CONFIDENCE
COMPARED TO THE THURSDAY AND FRIDAY RECORDS. THIS IS DUE TO THE
ANTICIPATED INCREASE IN CLOUDS AND PRECIP CHANCES. IN ADDITION TO
RAIN, SATURDAY THROUGH TUESDAY WILL ALSO FEATURE SLIGHT CHANCE FOR
THUNDERSTORMS AS WELL. NOTHING REALLY STANDS OUT AT THE MOMENT
FOR ANY POTENTIAL SEVERE THREAT.
DAILY RECORD HIGH MAXIMUM TEMPERATURES
