AREA FORECAST DISCUSSION National Weather Service Charleston WV 320 AM EST Fri Dec 6 2019

SYNOPSIS. Weak system Friday. Dry for the weekend, getting milder into early next week with rain developing Monday. Strong cold front Tuesday. Colder Wednesday/Thursday.

NEAR TERM /THROUGH SATURDAY/. As of 300 AM Friday .

For today, a passing low to the north will drag a weak cold frontal boundary spreading showers across the CWA. My initial thinking was that the chances for precipitation were slim, however after looking at the moisture profile and seeing how a fair amount of frontogenetical forcing exists along with a vort max accompanying the front, decided to not go as conservative on the PoPs and QPF. Used a blend of modest QPF amounts from various models and added a few HiRes ones as well. The outcome was still a little conservative, but dry air filtering in quickly behind the front should cut off showers relatively quick.

The front should make its way through rather hastily with decent flow aloft and drop showers off along the way through the afternoon into early evening when the front makes its way south out of the area. With a tightening of the gradient winds will pick up gusting to about 20KT areawide, so a breezy day in store until winds calm down after fropa with the gradient slackening. Temperatures wont fray too far from seasonable during the day however will deviate considerably at night. During fropa a rain/snow mix will begin in the mountains and change over to all snow fairly quickly as the cold air dominates into sunset. The extreme elevations in the northeast mountains should see a good dusting up to half an inch with the surrounding areas maybe seeing just over a trace amount. The bulk of the snowfall will happen just after sunset and wind down quickly as the moisture column and dendritic growth zone will be cut off with very dry air being filtered into the upper levels.

A good clearing will take place overnight allowing radiational cooling to ramp up dropping temperatures into the mid to upper 20's across the board. High pressure will build in promoting fair weather to start Saturday off and will continue into the next period.

SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/. As of 235 AM Friday .

Transition period from zonal flow aloft to southwesterly as a baroclinic zone strengthens over the central part of the lower 48. Short term forecast is dry with high pressure departing into New England and off the Atlantic Coast. Should get some modest recovery in the 850mb temperatures despite any lack of appreciable war air advection and will see milder readings heading into the end of the weekend.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. As of 235 AM Friday .

Much more active in the long term with a dramatic increase in moisture in a more southerly flow tapping into the Gulf. Lower level moisture transport magnitude increases sharply, as do the disturbances running through the 500mb southwesterly flow. Result is going to be a large areal coverage of precipitation from the lower Mississippi Valley into the Great Lakes and northeast that will be slow to have any sort of eastward progression through the Appalachians. Much of this can be attributed to the track of the surface low northeastward towards Labrador, but will finally get kicked out by a cold Canadian airmass mid week from a higher amplitude 500mb lobe dropping into the Great Lakes. Colder airmass to settle in behind the cold front with possible bouts of upslope/lake enhanced precipitation in the WNW flow.

AVIATION /08Z FRIDAY THROUGH TUESDAY/. As of 1230 AM Friday .

During this period VFR will remain dominant until this afternoon as a wave associated with a low passing by to the north drags in a weak front which will spread light showers across the area into the evening when the feature finally exits to the southeast. MVFR CIGs will be brought in by said feature and overspread all terminals with increasing chances of showers through the afternoon as it moves southeast. Brief periods of MVFR VIS are possible in showers during the afternoon and a wind shift takes place, changing over from southwest to northwest during this time frame which will initiate some gusty winds up to 20KT and subside after frontal passage. A window of IFR CIGs will affect EKN/BKW in the evening, however they should lift by the overnight hours when clouds clear out to the south by early morning at which point VFR will dominate thereafter.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SATURDAY . FORECAST CONFIDENCE: High.

ALTERNATE SCENARIOS: Timing of precipitation and associated restrictions may vary from forecast.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
