Marine Weather and Tide Forecast for Little Creek, DE

NEAR TERM /THROUGH TUESDAY/
Just minor tweaks made to the forecast, but overall, it is on track.

The cold front is crossing the area at this hour, and will move off the coast around midnight. This will result in mostly clear skies after midnight. In wake of the front, should observe an increase in surface winds where winds may occasionally gust up to 20 mph overnight. Overnight low temps will range from the teens to mid 20s across the region so when factoring in the wind, we'll likely have wind chills in the single digits to low teens by Tuesday morning.

For Tuesday, cold Canadian high pressure will build out of the High Plains, slowing inching toward the Mid-Atlantic region.
This will be the start of a reinforcing cold airmass through mid-week. Temps will struggle to reach the freezing mark with many locations topping out in the 20s to low 30s for highs under partly to mostly cloudy skies. A shortwave aloft will also be passing through in the afternoon, so may see some isolated flurries late in the day north and west of the I-95 corridor.
Confidence in this is low as the airmass behind the front is quite dry, so have left this potential out of the forecast grids at this time. In addition to the cold temps, a modest pressure gradient will set-up over the region. So, Tuesday will be quite breezy with wind gusts up to 30-35 mph possible. This should result in wind chills remaining in the teens for Tuesday afternoon.

SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/
For Tuesday night through Wednesday night, high pressure will build across the Ohio River Valley and weaken as it approaches the southeastern states. Meanwhile, low pressure drifts offshore of the Canadian Maritimes. In between the two, a tight pressure gradient will keep a steady west to northwest flow across the area. Winds will likely gust 20-30 mph or higher at times through Wednesday. Winds will weaken some by Wednesday night.

For Thursday, high pressure dissipates to our south, as a cold front weakens as it approaches from the west. As the front approaches and weakens, there is a chance for snow showers to move into the western half of the area during the afternoon.

Temperatures for Tuesday night through Thursday will be below normal.

LONG TERM /FRIDAY THROUGH MONDAY/
On Friday, a warm front will lift north of the area, allowing temperatures to moderate back above normal. As we move into Saturday into Saturday night, a cold front is expected to move across the area. Most areas will be warm enough for any precipitation that starts our as snow to change over to rain during the day Saturday. The front will shift offshore by Saturday night, then there is a chance a developing coastal storm could affect the area later Sunday into Sunday night.
