Key Messages,
- Warm overnight
- Showers increase from NW to SE as cold front approaches
No significant changes to the forecast as the forecast is tracking well.
Prev Disc, Some record highs have already been broken today (notably KHSE), with some others still being threatened, but will be contingent on amount of sunshine able to peak through multiple cloud layers. Line of showers been streaming over the Crystal Coast through bulk of the day will persist for a few more hours but activity wanes while pushing offshore this evening. Winds remain breezy out of the SW keeping WAA in place until the cold front arrives. Precip activity picks back up ahead of the front just after midnight inland, through the early morning hours for Inner Banks, rainfall on the order of a tenth of an inch or two. Expecting the cold front to be bisecting the FA by sunrise with sharp veering of winds to NWerly directly behind the front. Mints in the low 60s for places that remain ahead of the front, low 50s far inland zones where front passes through earlier.

Key Messages,
- Light rain first half of the day
- Early morning highs (60s) as temps fall through the day (50s) behind the front thanks to strong cold air advection
The initial cold front is expected to push offshore shortly after sunrise SUN with a second reinforcing front to cross through the afternoon. Pops 40-75% as the front moves NW to SE across ENC. Up to a 1/4" of rain is possible, with the highest amounts likely north of US 64. Rain will exit the OBX quickly early Sunday afternoon as colder and drier air rushes in behind the front. Have a mention of SChc thunder in the grids across portions of the OBX given how anomalously warm low level flow is underneath a stout trough aloft pivoting over the coast. Precip ends for OBX by mid-afternoon with skies clearing W to E behind the front.
High temps will occur early Sunday morning (low to mid 60s) with temps dropping through the 50s the rest of the day as strong CAA develops.
NWerly winds peak late afternoon into the evening behind the reinforcing front. Gusts in the low 30kt range are expected, with strongest winds forecast over portions of the OBX. Notable, but not quite reaching headline criteria at this point.

Key Messages
- Return to colder temperatures early next week with dry conditions
- Low pressure system mid to late next week will bring next chance of rain, with some potential (20-30%) for a wintry mix or light snow as it moves offshore
Sunday night, In the post-frontal air mass on Sunday night, temps will tank to the mid to upper 20s across the coastal plain and 30s along the beaches.
Early next week, Colder temperatures and dry weather is forecast for early next week as high pressure moves over the Southeast and a deep upper trough remains over the NE CONUS. Highs 45-50 for Mon, then into the 50s to low 60s Tuesday and Wednesday. Cold lows in the 20s for interior zones Mon night, then moderating into the 30s through mid week.
Late next week, Building signal that a low pressure system will move across the East Coast Thursday or Friday, but guidance continues to struggle with the strength, location, and timing of the system. Periods of rain are possible, and there is potential (20-30%) for a changeover to a wintry mix or snow as the system pulls away from the coast. Still too early for any discussion on impacts or accumulation potential.

Key Messages
- Brief period of LLWS likely this evening
- Another round of low stratus possible late tonight into early Sunday morning
Primarily VFR ceilings and visibility are noted across ENC. Though we do have some lingering MVFR ceilings currently noted across the OBX. Expect clouds to continue to lift this evening with at least a few hour period of VFR ceilings and vis across ENC tonight as a steady SW'rly wind persists across the region keeping us well mixed tonight. Cold front currently well to the west of ENC will then sweep E'wards after midnight and track across the area through the morning hours on Sun. This is forecast to bring a period of MVFR ceilings 2-3 kft starting from W-E tonight. Have PGV/ISO terminals going down to MVFR ceilings between 8-9Z and EWN/OAJ terminals going down between 10-12Z. Mvfr ceilings should quickly progress E'wards and eventually push offshore by late morning Sun as the front pushes offshore. Once the area goes VFR conditions will remain VFR through the rest of the period Sun. Scattered to numerous showers likely to accompany the front late tonight and Sunday morning. Precip will push east of the terminals by mid morning Sunday. Sw wind gusts 15-25 kt through tonight, becoming NW gusting 20-25 kt Sunday. This could lead to crosswind issues on EWN and ISO runways Sun. Could also see a brief period of LLWS between 0-6Z given the very strong winds aloft and have included this at all TAF sites. Generally expect LLWS values of 40-45kt at 1.5-2.0 kft during this timeframe before concerns ease after 06z.
Outlook: Pred VFR conditions expected through the period with high pressure in control.
