Key Messages,
- Chance of rain later this afternoon (20%-30%). Cool especially inland.
Main focus today will be inland temperatures and if we see any afternoon showers. A cold front has just about cleared our area. As high pressure nudges southward, northeast winds will create a classic cold air damming situation today, especially for our inland counties. Here we have likely hit our high for the day (mid 50s), as temps slide back into the 40s by sunrise, and likely hold here through afternoon. Closer to the coast, won't be quite as chilly but temps will likely will be pretty steady today in the 50s. The front mentioned above will try to return northward as a warm front later today. The HRRR, regional Canadian and NAM all show spotty showers this afternoon as this happens. Bufkit cross sections show good moisture and lift between 5kft and 10kft, so a few sprinkles or a light shower is possible after 18Z. With very dry air above this moist layer, if we see any showers, QPF amounts are likely to be around a trace to a hundredth or two. If we see a few rays of sunshine today it would be most likely this morning, and toward the OBX. Otherwise with good moisture in the mid levels, becoming cloudy will be the general rule today.
Tonight As of 115 AM Friday,
Key Messages,
- Rain showers early evening.
Rain chances increase along the warm front mentioned above by this evening. Highest chances will shift toward the OBX. As the front lifts through the area, drier weather builds in after midnight.
Saturday through Thursday As of 115 AM Friday,
Key Messages,
- Above normal conditions Saturday, Sunday and Monday with temperatures in the 60s and 70s!
- A pattern changing arctic cold front will move through the area late Monday with well below normal conditions returning through early to mid next week
Saturday is looking to be especially nice. With high pressure ridging over our area, H925 temps climb to +8C, which will help part of our area making a run toward 70 for highs! 925 temps cool about 1.5 degrees Sunday, and with increasing high clouds, temps won't be quite as warm or generally in the 60s.
The main trend with our arctic cold continues to be to slow it down. At one point a later Sunday FROPA is now later Monday. With strong warm air advection (WAA) Monday, highs will surge into the middle 70s or roughly average highs for late December for West Palm Beach, Fl! A thin line of showers may accompany the front Monday evening, but the bigger headline will be the abrupt return to winter. Below temps expected Tuesday and beyond, with highs in the 40s to near 50 and lows mainly in the 20s. Ouch!

Key Messages
- VFR through the bulk of today
- Deteriorating flight cats tonight
- Potential for LLWS early Saturday morning
VFR BKN to OVC mid level clouds will linger through early afternoon with light winds out of the NE. Mvfr CIGs are then expected to develop from south to north, recovering to VFR shortly after 00Z. A slight chance of light showers (15-25%) is possible for all TAF sites through the day with chances increasing along the OBX tonight (30-50%). Overnight, SCT mid level clouds will be accompanied by light SW winds, and there's potential for 35 kt of LLWS at 20,000 ft for all TAF sites early Saturday morning.
Outlook: Periods of sub-VFR CIGs will be possible through the weekend. Early next week, a period of gusty southwest winds appears likely, with gusts as high as 20-25kt.
As of 130 AM Friday,
Key Messages,
- Small Craft conditions will continue this afternoon over the coastal waters and Pamlico Sound through sunrise
- Additional rounds of Small craft conditions likely this weekend and into early next week
Surge of northeast winds moving over the coastal waters now. Winds will subside by mid morning but seas will remain elevated across offshore waters until later today at the earliest, lingering into the overnight hours for the offshore Gulf Stream waters into Friday evening. Seas peak at 6-8 feet.
Outlook: Winds temporarily improve over the weekend, but seas may remain at or above 6 ft as long period swell moves into marine waters, especially central waters off Hatteras. Winds increase again Monday morning in advance of a strong cold front with widespread Small Craft conditions and possibly Gale conditions developing. Waters from Oregon Inlet to Ocracoke may be under continuous headlines for the next several days.
