Area Forecast Discussion National Weather Service Wilmington NC 341 PM EDT Mon Apr 19 2021

SYNOPSIS. High pressure will build over the area this evening and overnight. Slight chance of rain along the coast Tuesday night. A dry cold front will cross the area late Wednesday, with cool and dry high pressure moving in Thursday and Friday. A storm system will approach from the Gulf Coast states late Saturday into Sunday. High pressure returns early next week.

NEAR TERM /THROUGH TUESDAY NIGHT/. Deep dry and cool NW flow developing behind exiting low pressure. Sea breeze produced onshore flow coming against the N-NW flow building in which in turn produced some convergence just along the Cape Fear coast, but subsidence and dry air took over shortly thereafter with gusty N-NW flow. Winds will lighten and veer tonight into Tues as weak high pressure migrates eastward across NC. This will allow for decent radiational cooling tonight with temps dipping just below 50 most places away from the beaches.

Winds will continue to come around with onshore flow developing on Tues. This will help push cool air onshore, although water temps are well into the 60s to near 70 now. This will keep beaches closer 70 with inland areas reaching into the mid 70s. A shortwave will ride by late Tues into Tues night. This will produce more in the way of mid to high clouds late Tues, but a passing shower is possible with low end pops included in forecast from late evening Tues into early morning hours. Temps should in the mid 50s most places Tues night.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. Dry cold front will move across the area on Wed. Strong warm advection ahead of the front will push highs well above climo and lead to rather gusty winds. Gusts 30 mph are not out of the question both ahead of and behind the front. Air mass is also very dry so Wed has the potential to be a significant fire weather day. Partial thickness values give highs in the 80s with relative humidity potentially dipping under 30%. Front passes late Wed afternoon with an unseasonably cool air mass building in. Strong cold advection Wed night will drop lows well below climo. Wind will stay up all night, making frost very unlikely, but lows in the upper 30s to lower 40s certainly seem possible.

Thu is another tricky forecast. Incoming air mass is impressively cold front late April. The problem is the air mass is very dry and the sun is getting higher in the sky given that it's late April. Cold advection shuts off by mid-morning Thu and downslope flow will set up. All of these factors should lead to rapid air mass modification. In a fairly recent event involving very dry air, many areas had a diurnal range in excess of 40 degrees. Thu could be another day with fire weather concerns as well, mainly across NC. Strong winds will be present just above the top of the mixed layer. If temperatures end up a little warmer, as little as 2 degrees, instead of mixing 15 to 20 kt winds to the surface winds in excess of 30 kt could be mixed to the surface. The key will be temperatures Thu afternoon and what height the jet is at. Did bump up both sustained winds and wind gusts, but this will be something to keep an eye on.

Thu night could be a potential problem as far as frost goes. Light to calm winds and clear skies will allow for excellent radiational cooling. In addition the air mass will be excessively dry. Nearly ideal radiational cooling conditions will exist and could allow for lows into mid 30s in the coldest spots. Not expecting a freeze at this point, but frost is certainly a possibility, even with how dry the air mass is.

LONG TERM /FRIDAY THROUGH MONDAY/. Extended will be marked by weak high pressure at the start and end with storm system moving across the area Sat into Sun. Right now the weekend system looks like it would be a decent rain producer, but confidence is on the low side. Guidance has not been doing all the well with pop/qpf in our area the last few days. However, at least part of this is down to the pattern aloft and it appears the pattern aloft will transition out of the weak/split flow pattern. This does boost confidence a little. The details remain fuzzy given the extended time range, but warm front will lift across the area at some point on Sat with the low passing over or just inland of the forecast area Sat night. This could lead to some severe weather potential late Sat or Sat night, but again confidence in the weekend forecast is very low right now.

- Dry conditions Fri and Mon.

- Potential for 0.50" to 1.00" of rainfall Sat into early Sun.

- Temperatures below climo Fri increasing to near to slightly above climo Fri night through Mon.

AVIATION /20Z MONDAY THROUGH SATURDAY/. Satellite indicates some bubbly CU from Brunswick, northeast through New Hanover and Pender counties. Went with VCSH for ILM with no convection near the other sites. Some light fog possible tonight.

Extended Outlook . VFR. A moderately strong cold front expected to cross the region Wednesday night has only a low chance of convective showers associated with it.

MARINE. Through Tuesday Night: Low pressure will continue to track off to the northeast with gusty NW-N winds up to 20 kts on the back end with a spike up in seas up to 3 to 4 ft. Winds will continue to veer around to the N-NE and diminish by morning as high pressure migrates eastward across North Carolina. Once the high reaches offshore on Tues, winds will become onshore to SE by Tues aftn and increasing up to 15 kts out of the S-SW by Tues night. Seas will be down less than 3 ft through much of Tues into Tues night.

Wednesday through Saturday: Waters will become fairly active mid to late week. Dry cold front approaches from the west on Wed with tight gradient increasing southwest flow to a solid 20 kt through Wed afternoon. Offshore flow develops in the wake of the front with speeds in excess of 20 kt as strong cold advection sets up. Flow weakens on Thu and slowly backs to southwest as high pressure builds in for Fri. Low pressure approaches from the west on Sat with southerly flow increasing to 20 to 25 kt later Sat and Sat night. Seas start out around 2 ft but increase to 3 to 4 ft in the afternoon as southwest flow picks up. Seas peak around 4 ft Wed night before dropping to 2 ft or less by Thu morning as offshore flow sets up and then starts to weaken. Seas build to 4 to 7 ft later Sat ahead of the next system.
