As of 200 PM Sunday... KEY MESSAGE 1... The cold front that moved across central NC has stalled across the eastern Coastal Plain. Drier air will continue to move into the region from the northwest but lingering moisture near the front could lead to a stray shower or storm this afternoon along the Coastal Plain. The latest surface analysis shows the slow moving cold front now located across the eastern Coastal Plain with northwest winds across all of the area including at Fayetteville, Goldsboro and Clinton. Drier air has been filtering into the region thanks to a northwest or westerly flow in the low levels. The RAOB at KGSO this morning noted a PW of only 0.94 inches which is around the 18th percentile. The drier air combined with good mixing has allowed dew points to fall into the upper 50s at KINT, KGSO, KEXX, and KHNZ and the lower 60s across most of the remainder of the Piedmont. Further east and southeast across the Coastal Plain and Sandhills moisture lingers with dew points in the upper 60s to around 70. This has resulted in a bit more cumulus clouds and perhaps a little vertical growth near and just behind the front from Maxton to just southeast of Fayetteville to just south of Goldsboro. Wouldn`t be shocked if a rogue shower or storm develop near or east of this line through around 6pm but the coverage and intensity should be very limited and more favored to the east. Generally fair weather is expected overnight with a northwest to westerly flow aloft, An approaching mid level disturbance may trigger a weak area of low pressure to develop in the Carolinas overnight on the front, or at least buckle the front and the moisture back west slightly. Some of the CAMs, primarily the HRRR suggest a rogue shower could develop late tonight across southern or southeastern areas, there is very little support for this in the other CAM guidance so will exclude any overnight PoPs. There could be some patchy fog or low stratus across the Sandhills and southern Coastal Plain toward day break as well. Lows tonight should range in the lower 60s in the Triad and VA border counties, with mid 60s in the Triangle and southern Piedmont and the upper 60s in the Sandhills and Coastal Plain. Could see a few upper 50s in the typically colder spots such as Henderson and Sanford. These lows range from 1 to 4 degrees below average. Even more notable will be the dewpoints in the mid 50s to mid 60s which will result in a much more pleasant morning for the first day of school in many locations. KEY MESSAGE 2... There will be a slight chance for showers and thunderstorms Monday afternoon along and east of the I-95 corridor. The cold front moving across central North Carolina today will become hung up along the Atlantic coastline tonight into Tuesday. The bulk of the convection that will occur Monday will be along the immediate coastline, but models have inched the western edge of the precipitation slightly farther to the west than they were yesterday. Other than around Fayetteville, it still appears that nearly all precipitation that occurs should remain east of I-95, and chances for storms are anywhere between 20-40%. The Storm Prediction Center does have a marginal (level 1 of 5) risk for severe storms along the coastline, just clipping the southern tip of Sampson County. Again, it is along the coastline where the greatest instability and wind shear will remain. Key Message 3: Diurnally based convection returns to the forecast on Wednesday, maximized on Thursday. KEY MESSAGE 3... The front will inch northward Wednesday and Thursday, eventually extending from Elizabeth City to Monroe. The chance of showers/storms Wednesday afternoon should generally be to the southeast of the Triangle, although all locations are likely to see at least some minimal precipitation Thursday. As the front retreats back to the coastline for the weekend, precipitation will become more scattered, but locations in the southeast will have higher chances of rain than locations in the northwest. Temperatures should be near normal for late August, with highs around 90 and lows around 70. && .AVIATION /00Z MONDAY THROUGH THURSDAY/... As of 715 PM Sunday... Fair weather and VFR conditions are expected through the overnight hours across all of central NC. However, after midnight there`s a chance of some low stratus and fog development mainly across the south and east which could cause some temporary restrictions at KRWI and KFAY. Outlook: A stalled front across the Coastal Plain could produce some isolated storms near KFAY/KRWI Monday afternoon. As the air mass becomes gradually more moist over the outlook period, the risk of scattered afternoon and evening storms will gradually increase, with the greatest chances on Wednesday and especially Thursday. There will also be an increase risk of late night and early morning fog and stratus, especially across eastern and southern locations. && .RAH WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Blaes/Green AVIATION...CA/Blaes
