Area Forecast Discussion National Weather Service Wilmington NC 600 AM EST Sun Jan 19 2020

SYNOPSIS. Cold and dry conditions will develop today and persist for much of next week as arctic high pressure builds in.

NEAR TERM /THROUGH MONDAY/. Light rain showers ahead of a cold front today that will push through the Carolinas this afternoon. Before the onset of cooler air moving into the region, high temperatures today will reach into the low to mid 60s before dropping this afternoon and evening. Rain showers expected to end by this afternoon Below freezing temperatures are expected with lows in the upper 20s inland to lower 30s near the coast.

High pressure returns Monday with cool northerly winds across the area with highs reaching into the low to mid 40s, which is about 10 degrees below normal for mid January.

SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/. Cold and dry conditions for the short term period as arctic high pressure builds in. Expect widespread lower to middle 20s for actual temperatures Tuesday morning with similar values Wednesday. The boundary layer winds remain elevated both mornings so guidance could be a little cool. Highs Tuesday will be a grind to reach north of 40 degrees most areas. Its worth watching the evolution of the strong vort max moving across Tuesday as albeit rare these, can with pure dynamic lift, crank out a little qpf.

LONG TERM /WEDNESDAY THROUGH SATURDAY/. Mid level ridging will follow the early week trough with a warmup in store. It will take a little time however as Wednesday and Thursday will remain cold. A cold front late in the work week or early in the weekend will be the next significant system to move across. Global/medium range guidance still has some timing differences so prudence calls for a day or two of pops this far out in time.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. The cold front will push off the coast later this morning, with gusty west winds. Any pockets of IFR ceilings will abate in a few hours. Look for falling dewpoints and clearing skies this afternoon. Diminishing northwest winds this evening.

Extended Outlook . VFR conditions thru next week. Arctic high pressure will dominate.

MARINE. Small craft advisory continues until this afternoon as a cold front passes and brings a wind shift from the southwest to the northwest around 15 to 25 kts with gusts to 30 kts and seas between 4 and 8 feet at 6 to 8 seconds. High pressure returns Monday with much cooler temperatures and wind/wave conditions improving.

Blustery and rugged marine conditions still expected for the first few days of the short term and extended forecast periods. North winds between 15-25 knots will be in place Tuesday and Wednesday probably highest Wednesday. Guidance has ticked up with speeds so gale conditions are now at least a remote possibility with almost certain small craft conditions. Significant seas, with the higher values across the outskirts of the forecast zones will be reaching or just above small craft criteria during this time as well. Elements relax considerably with a return flow late in the period.

ILM WATCHES/WARNINGS/ADVISORIES. SC . None. NC . None. MARINE . Small Craft Advisory until 5 PM EST this afternoon for AMZ250- 252-254-256.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
