Synopsis: Warm weather will continue through tonight with increasing chance of showers. Gusty showers and isolated thunderstorms will accompany a cold front that will cross the area Thursday morning. Dry high pressure will build in behind the front Thursday afternoon into the weekend. The high will shift south of the area early next week. Temperatures near to slightly below normal into the weekend will start warming early next week.

Near Term - Through Thursday
As of 415pm Wednesday...The FA is now well into the warm sector well ahead of the strong eastward moving cold front that will be working its way across the windward side of the Appalachian mountains early this evening. Various model soundings illustrate moisture availability remains at or below 800 mb which at this juncture is primarily involving Atlantic Ocean Moisture. As a result, have continued in carrying a low chance for light rainshowers late this afternoon and well into this evening. As the mid-level s/w trof continues it's progression eastward, it taps plenty of Gulf of Mexico moisture and carry it northward. Model trends have been narrowing the highest moisture content of the atm for this event, including Gulf and Atlantic combined moisture, to occur prior to sunrise Thu thru midday Thu. Models indicate Peak forecast PWS of 1.5 inches and excellent low level wind shear, both speed and directional changes during this 6 to 9 hr time-line. However, instability is lacking which is usual for this time of the year, ie. low Cape and high shear. With 50 kt winds forecast at just 800 feet off the sfc, a well mixed moderate to strong shower could produced a strong surface wind gust with thunder lacking. Will however, indicate isolated/low chance for thunder during the 6 to 9 hr peak of pcpn occurrence. Temperatures will be running 3 to 4 categories above normal which will make it seem even warmer given the brief Arctic temperatures experienced from Sunday night thru late last night

Short Term - Thursday Night Through Friday Night
As of 300pm Wednesday...High pressure will build in behind exiting cold front Thurs night through Fri night. A very broad mid to upper level trough will remain over the eastern CONUS though with high getting suppressed a bit further south heading into the weekend. This leaves a generally drier and cooler air mass over the area. Temps will drop a good 30 degrees Thurs night with temps down into the mid 30s by daybreak. The 850 temps drop out from near 12c Thurs afternoon down to -5 by Fri night. This Cold Air Advection will keep daytime highs below normal for Fri with most places closer to 50 most of the aftn. Fri night will have a better shot at more decent radiational cooling as winds lighten with mainly clear skies. Temps should drop down below freezing most places

Long Term - Saturday Through Wednesday
As of 300pm Wednesday...A very broad mid to upper trough will remain over the eastern CONUS. This will maintain more of a progressive flow in the northern stream, while surface high pressure will remained sprawled across the deep south over the weekend, migrating closer overhead by Monday. Overall expect dry weather through the weekend into early next week with a good deal of sunshine. Temps will be just on the cool side through the weekend, but will begin to warm through early next week. Models continue to show low pressure riding up off the Southeast coast early next week, but may be too far away to produce any weather. The next appreciable chance of rain will most likely come during the middle of next week as a cold front reaches the area late Tues into Wed.

Marine Discussion
Near Term - Through Thursday: As of 400pm Wednesday...Gale Warning remains in effect for all waters. The surface pg will continue to tighten well ahead of the eastward progression of the strong cold front now located on the windward side of the Appalachian Mountain chain. By daybreak Thu, the north-south oriented cold front will be located along the I-95 corridor. The tightened surface pg will peak Thu morning just prior to the cfp. After Fropa, models quickly relax the surface pg during Thu aftn. The Cold Air Advection will not nearly be as intense like what occurred Sunday into Sunday night due to the Cold Air Advection involved is NOT of Arctic origin. Winds will drop thru Small Craft Advisory Thu afternoon and continue trending lower Thu night. Significant seas will primarily be short period dominated, ie. wind driven waves, with no long period ground swell really involved. Seas will peak in the 6 to 11 foot range with the highest seas off Cape Fear and Romaine respectively with the shallow shoals helping with heights. "Victory at sea conditions" will help describe the rather chaotic seas due to wind direction changes during the next 24 hrs. From the pre-dawn Thu hrs thru midday Thu, expect the best chances to see widespread showers with embedded tstorms.

SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... As of 300pm Wednesday...High pressure will build in behind exiting cold front. Winds and seas will remain elevated with Small Craft Advisory through Thurs night in NW to N winds up to 15 to 20 kts initially. By Fri morning, seas will diminish in off shore flow and will continue on a downward trend through Fri. Expect lighter northerly winds Fri afternoon through Fri night with seas down under 4 ft.

LONG TERM /SATURDAY THROUGH MONDAY/... As of 300pm Wednesday...High pressure sprawled across the deep South over the weekend will shift closer overhead and then off the Southeast coast by Sunday night. This will generally maintain a light off shore flow 5 to 10 kts most of the time and seas less than 3 ft
