Area Forecast Discussion National Weather Service Blacksburg VA 619 AM EST Sat Dec 14 2019
SYNOPSIS. A cold front will move across the region today and tonight. High pressure will cover the eastern United States on Sunday. Another low pressure system will track across the central and eastern United States on Monday and Tuesday, followed by high pressure on Wednesday and Thursday.
NEAR TERM /THROUGH TONIGHT/. As of 350 AM EST Saturday .
A couple of upper level troughs will bring more rain to the area today. The first trough and a surface low are tracking across the southern Ohio Valley this morning. The band of showers with this feature is currently moving across the mountains. Rainfall amounts will range from a quarter to half an inch. The second trough has the cold front attached to it. This trough will merge with the first one over the Ohio Valley, keeping the bulk of the dynamics and heavy rain showers north of the area this afternoon. Rain will come to an end east of the Blue Ridge during the afternoon. However, a deformation zone with this merged trough will bring light rain to the mountains with an additional one to two tenths of an inch of rain. This deformation zone moves north of I-64 this evening.
The cold front will track across the region this afternoon. Not much cold air behind it, but enough to have high elevation snow showers and patchy freezing drizzle along western slopes into Sunday morning. Only light accumulations of snow and ice are expected. Pressure rises behind the front will bring breezy and gusty winds to the area during the afternoon. A cross-barrier jet (35 kts) along the Blue Ridge increases overnight with the strongest winds remaining along ridges above 3000 feet. With the lack of strong cold air advection, there are no plans to issue any headlines for winds.
Temperatures this morning have warmed into the low to mid 40s. Temperatures will continue to rise today into the mid to upper 40s across the mountains and 50s east of the Blue Ridge. Cool air behind the front will drop temperatures into the 30s tonight.
SHORT TERM /SUNDAY THROUGH TUESDAY NIGHT/. As of 340 AM EST Saturday .
Lingering upslope behind the departing low will end early Sunday morning as a wintry mix of snow, drizzle, and freezing snizzle but any accumulations look to be little more than a trace and mostly confined to the higher elevations. The remainder of Sunday will see a brief break in our active pattern before another frontal boundary starts to push in from the west. Flat low amplitude flow aloft will not be give the front a lot encouragement so it will not make a lot of progress into the region. This will confine precipitation chances Sunday night to locations north of route 460 and mostly up near the Interstate 64 corridor. Temperature profiles will be favoring some snow at the start, then a transition to a wintry mix before going to all rain shortly after daybreak Monday. Any accumulations Sunday night will again be quite light and mostly up near I64. With the lazy front still not making any headway on Monday expect little in the way of showers for Southside or the NC/VA piedmont, with rain chances increasing to the west and north and showers likely up near I64. Winds will become gusty across the Mountain Empire Sunday night into Monday as the low level wind field amplified ahead of the front.
A broad upper trof finally digs into the midwest and starts to push the front through the Appalachians and central mid Atlantic region Monday night with widspread rainfall expected. The front moves through west to east late Monday night into Tuesday and precipitation will gradually taper off to upslope showers west of the Blue Ridge. With much colder air surging in behind the front expect the upslope precipitation west of the Blue Ridge to transition to snow showers from later Tuesday afternoon into Tuesday night, with any accumulations at the higher elevations generally an inch or less. Winds behind the front will become quite strong and gusty, especially along and west of the Blue Ridge with gusts over 45 MPH possible through Tuesday night.
Temperatures will be running well above normal on Sunday and Monday with readings well into the 50s east of the Blue Ridge, mid 40s to lower 50s to the west. Temperatures start to tumble on Tuesday west of the Ridge behind the front, though readings to the east will have a chance to surge into the 50s once again before the front moves through.
LONG TERM /WEDNESDAY THROUGH FRIDAY/. As of 200 PM EST Friday .
By Wednesday, enough drier air is expected to have arrived to both end the light snow showers and also clear out the remaining cloud cover, though winds will remain very gusty into Wednesday evening.
High pressure will head eastward through the southeast U.S. into Thursday, with our region experiencing no precipitation and little to no cloud cover. Once the center of the high reaches the GA/SC coast on Friday and low pressure moves east into the mid-Mississippi Valley, look for a return of southwest winds and both increasing temperature and moisture advection. At this time, no precipitation is forecast for Friday. However, cloud cover is expected to be on the increase. Any precipitation associated with the approaching low looks more likely to impact our forecast Friday night into Saturday, but that will be past the valid time of our current forecast.
Wednesday through Friday, temperatures are expected to average five degrees below normal.
Confidence in this portion of the forecast is moderate to high.
AVIATION /11Z SATURDAY THROUGH WEDNESDAY/. As of 620 AM EST Saturday .
Widespread LIFR ceilings and MVFR visibility with fog and light rain will continue through this morning. Conditions are expected to gradually improve later this morning into the afternoon when a cold front tracks across the region. Behind the front, west winds will become breezy and gusty, especially along the Blue Ridge. Upslope showers and patchy drizzle likely overnight to have western slopes (KBLF/KLWB) drop down to LIFR ceilings and MVFR visibility again.
Extended Aviation Discussion .
VFR expected areawide Sunday under high pressure. Another storm system will impact the region Monday into Tuesday. Mainly rain is expected with this system for our area with temperatures above freezing.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
