National Weather Service Wilmington NC
948am EDT Fri September 29 2023
High pressure will generally prevail through early next week keeping it mainly dry with temperatures near normal. An offshore trough could bring a few coastal showers toward mid next week.
Going forecast was mainly in good shape this morning. Other than tweak for latest conditions, no changes were made.
Near Term - Through Tonight
Surface high pressure, perhaps a bit weaker than previous days will remain in control of conditions today. There will be a little more sun today and this along with airmass modification will lead to high temperatures near 80 degrees or a little higher across southwest zones. A subtle push from the northeast will occur tonight dropping low temperatures Saturday a degree or two below this morning's numbers.
Short Term - Saturday Through Sunday Night
Confidence: High Main concerns: None
Strengthening surface high pressure is expected to remain centered to the northwest near the Great Lakes and ridge southward into the Carolinas while low pressure off the Mid-Atlantic coast moves farther away. Should stay dry locally with any showers likely staying well offshore. Main change from the previous forecast was to lower dewpoints as it should be a more favorable pattern for low- level drying. Temperatures should be on a slight downward trend through the period, reaching below normal late in the weekend.
Long Term - Monday Through Thursday
Confidence: Moderate to High Main concerns: None
No major changes from the previous forecast. Surface high pressure centered to the north will maintain rather dry conditions, especially inland, with mainly coastal showers possible starting mid week as an offshore trough moves closer to the coast. However, no significant rainfall is anticipated through the period. Temperatures should generally be pretty close to normal through the period.
Northeast winds in a 15-20 knot range are hanging on this morning across the waters with seas of 3-5 feet. By mid to late morning winds will diminish and settle into a range of 10-15 knots. A slight uptick is noted early Saturday morning as a subtle reinforcement pushes in. Significant seas will follow a similar trend dropping to 2-4 feet in time.
Saturday through Tuesday
Forecast confidence is fairly high this period as high pressure remains centered to the north which will maintain enhanced north/northeast winds. Significant wave heigheights will be elevated as well and the combination of winds and seas could produce a marginal Small Craft Advisory early next week.
Tides / Coastal Flooding
The higher than normal astronomical tides combined with onshore (east/southeast) swells and north/northeast winds (which enhance Ekman transport toward the coast) will lead to minor tidal flooding during the morning and evening high tides through at least early next week across coastal southeast North Carolina and northeast South Carolina as well as along the lower Cape Fear River from around downtown Wilmington south toward the coast.
