&& .NEAR TERM /THROUGH TONIGHT/... As of 255 PM Saturday... Northeasterly flow remains across the area this afternoon as surface high pressure sits over western New York. Some weak surface convergence across the northern I-95 corridor has lead to some enhanced cloud cover over this area and a few pop up low topped showers. This is consistent with RH cross sections which show much of the moisture below 750 mb. Forecast soundings also show very dry conditions aloft. Overnight expect some fog in the northeastern quadrant of the CWA followed by some MVFR/IFR stratus. This should begin around 9z and low clouds could linger across the east into the late morning or even early afternoon on Sunday. Highs today solidly in the mid 80s with overnight lows in the mid 60s. && .SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/... As of 255 PM Saturday... Hurricane Jose will continue the trek northward on Sunday off of the Carolina coast to our southeast. No real impacts are expected to central NC other than the potential for some cloudiness in the east with a band of showers perhaps progressing through the eastern portions of the CWA. A few wind gusts of 15-20 knots will be possible Sunday afternoon and into the evening. For the western half of the area, it may be hard to even realize clouds as things remain confined to the east. All in all a nice end to the weekend with low to mid 80s for high temperatures and lows Sunday night in the middle 60s. && .LONG TERM /MONDAY THROUGH SATURDAY/... As of 230 PM Saturday... As hurricane Jose moves north and passes well offshore, the primary impacts will be increased cloudiness in the east on Monday, and the northerly flow will maintain a slightly below normal trend in our high temperatures Monday and Tuesday. Highs will be in the low 80s across the north to mid 80s south both days. It`s difficult to confidently identify any forcing which might provide some convective focus from midweek onward. Initial weak troffing at the surface and aloft in the mid week will give way to high pressure in the midweek as the lingering surface trof is pushed south of the area, Highs Wednesday and Thursday will reach the mid to upper 80s, with some very low 90s possible across the southern tier. Weak cool air advection in easterly behind the surface trof will stall the airmass modification and cool highs a couple of degrees on Friday, with the modestly cooler airmass settling in to produce mostly lower 80s Saturday. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/...

As of 825 PM Saturday... Moist nnely low level flow will result in a period of LIFR-MVFR conditions centered over nern NC and sern VA late tonight-early Sunday, including as far wwd as RWI. The associated saturated layer will likely remain trapped beneath a strong, shallow inversion near the surface, such that LIFR-IFR conditions may linger at RWI until 14-15Z Sun. Much like Sat, a stray afternoon shower will also be possible at RWI and FAY. VFR conditions, with a nely wind that will increase into the 8-12kt range with diurnal heating on Sunday, are expected to prevail otherwise and elsewhere. Outlook: Continued nely flow between Tropical Cyclone Jose and high pressure centered along the New England coast will yield a good chance of late night-early morning stratus and an afternoon shower at ern TAF sites through Tue.
