Area forecast discussion National Weather Service Columbia SC 158 PM EST sun Dec 21 2014 Synopsis... a frontal zone will remain near the southeast coast through Tuesday. A series of low pressure systems will move northeastward along the front...keeping weather unsettled. A strong cold front approaching from the west will move through the forecast area late Wednesday or Wednesday night. && Near term /through tonight/... sub-tropical plume of moisture extending from central Mexico to the southeastern states continues to be evident on the water vapor imagery this afternoon. Visible imagery shows that skies cleared a bit across the central and northern midlands allowing temperatures to rise into the middle 50s. Isentropic lifting will increase late afternoon into early evening in response to the approaching shortwave from the Gulf Coast. Light rain expected to develop and move northward into the forecast area from the south around sunset. Isentropic lift maximizes over the forecast area during the 03z-09z time frame and the area falls within the right entrance region of a strong 120+ knot upper jet throughout much of the night...aiding in forcing for precipitation. Leaned towards the higher met pop guidance and will carry categorical probability of precipitation for the entire forecast area...with the highest probability of precipitation centered around the 06z-09z time frame. Temperatures will fall into the lower to middle 40s limited by wetbulb temperatures. Despite the high probability of precipitation overnight...total rainfall amounts are expected to be light at generally a tenth of an inch or less...with some isolated amounts closer to a few tenths of an inch. && Short term /Monday through Wednesday night/... models showing the bulk of the rainfall pushing north of the County Warning Area early Monday morning...and will have decreasing probability of precipitation during the morning. Still expecting scattered rainfall with some drizzle through the day. Wedge will hold strong Monday through Monday night. With plenty of cloud cover and northeast winds...temperatures will not recover much through the day Monday...with readings remaining mainly in the 40s. Overnight lows Monday night will also be in the 40s. Deeper moisture will return to the County Warning Area again during the day Tuesday...and with this increase the area will see an increase in probability of precipitation. Wedge may diminish and weaken late in the day Tuesday...which would allow temperatures to reach the 50s. With The Wedge breakdown and the expected return of warmer air...temperatures Tuesday night will not drop much and may even rise slowly through the night. Categorical probability of precipitation through Tuesday night. Stronger cold front is poised to move into the region Wednesday. At this time the upper support remains behind the surface cold front...with the surface front moving through Wednesday evening. Widespread rainfall will move through the region early in the day Wednesday...then should see a decrease in probability of precipitation late Wednesday into Wednesday night. With the warm air ahead of the cold front...Wednesday should be the warmest day of the period as temperatures rise into the upper 60s to lower 70s. Can not rule out isolated thunder on Wednesday if the upper support can catch up with the surface front...but at this time the confidence is not high enough to mention. Winds from Wednesday through Wednesday night will become strong and gusty...with wind gusts of 20 miles per hour possible. && Long term /Thursday through Sunday/... return to more seasonable temperatures behind the front. The models continue to show a dry airmass for Christmas day. Winds will remain breezy and gusty on Christmas day...then the gradient weakens by Thursday evening. Moisture may increase associated with another cold front moving into the area Saturday into Sunday. && Aviation /19z Sunday through Friday/... VFR conditions becoming MVFR after sunset...and IFR/LIFR late tonight through Monday morning. Skies have cleared a bit this afternoon but increasing clouds expected late this afternoon with lowering ceilings to MVFR around 00z ags/dnl/ogb and by 03z at cae/cub as isentropic lift increases ahead of approaching shortwave energy. Light rain should overspread the terminals from south to north overnight. Ceilings expected to drop to IFR after 06z with the rainfall and increasing wedge conditions. Persistent southwesterly flow aloft atop the northeasterly low level flow will keep wedge conditions in place after 12z which will result in lowering visibilities in drizzle and light rain with IFR/LIFR ceilings. Extended aviation outlook...widespread MVFR to IFR conditions expected Monday through Wednesday evening as a series of systems cross the region. Breezy conditions possible Wednesday afternoon into Thursday morning. && Cae watches/warnings/advisories... SC...none. Georgia...none. && $$
