248 AM EDT SUN OCT 12 2025
VALID 00Z MON 13 OCT 2025 - 00Z MON 20 OCT 2025
MODEL AND ENSEMBLE SOLUTIONS CONTINUE TO SEEM REASONABLY WELL
CLUSTERED, BOLSTERING OVERALL FORECAST CONFIDENCE. EXPECT LIGHT
EASTERLY TRADES INTO EARLY WEEK WILL STEADILY INCREASE MID-LATER
WEEK INTO NEXT WEEKEND AS HIGH PRESSURE BUILDS AND SETTLES TO THE
NORTHEAST OF THE STATE. MEANWHILE, AN UNSETTLING UPPER
LOW/TROUGH REMAINS FORECAST TO DIG SOUTH TOWARD THE STATE EARLY
WEEK AND THEN LINGER IN VICINITY MID-WEEK INTO NEXT WEEKEND. THIS
WOULD ACT TO POOL MOISTURE AS WINDS RESPOND/SHIFT SOUTHEASTWARD.
A RISING INVERSION AND INCREASING LIFT SHOULD FURTHER YIELD
INCREASED RAIN/DOWNPOUR CHANCES IN THIS WET PERIOD TO MONITOR.
