Area Forecast Discussion National Weather Service Columbia SC 629 PM EST Fri Feb 21 2020

SYNOPSIS. Dry and cool high pressure will build over the region through the weekend then move off the Southeast Coast Monday. There will be increased moisture and rain in the forecast area Sunday night through Tuesday in the southerly flow as a cold front crosses the region.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. High pressure to the west will continue to move toward the southeastern US while low pressure off the coast lifts northeast.

As a cold, dry airmass settles over the forecast area, light winds and clear skies will lead to a fairly strong inversion developing tonight. Temperatures are expected to bottom out in the 20s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/. Dry weather will dominate the region through the weekend as high pressure begins the weekend just west of the area and slowly crosses the forecast area through Sunday afternoon. Sunday night the high will move offshore ahead of the next low pressure system. Moisture and clouds will begin increasing late Sunday afternoon and evening as flow begins turning southerly and moisture slowly returns to the region. Models continue to slow the system moving into the area Sunday night and with considerable dry air to overcome has decreased pops to slight chance for late Sunday night and early Monday morning. High temperatures will be in the mid 50s Saturday and near 60s on Sunday with overnight lows in the lows 30s Saturday night and with the southerly flow warm to the low 40s Sunday night.

LONG TERM /MONDAY THROUGH FRIDAY/. Low pressure will move from the south central Plains Monday morning through the MS Valley and into the Great Lakes on Tuesday. This will push a cold front across the Gulf States with increasing southerly flow and chances of rain for the forecast area Monday and Monday night. Models continue to differ slightly with pushing the front offshore or stalling it near the coast however the ECMWF and GFS agree some moisture lingering across the area through Tuesday with another disturbance moving along the coast Tuesday night and Wednesday. A deep and fast moving upper level trough will move through the region Wednesday night and early Thursday finally pushing the front well away from the region. Dry conditions are expected for Friday as a high pressure ridge builds into the area. Temperatures will be above normal through Wednesday then lower to below normal Thursday and Friday.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. High confidence in VFR through the entire TAF period.

A cool and dry airmass will settle over the area with clear skies through Saturday. Light north to northeast winds this evening becoming variable overnight.

EXTENDED AVIATION OUTLOOK . Restrictions expected to develop Monday as a low pressure system moves into the Southeastern states. Restrictions may continue at times through at least Tuesday as front stalls near the area.

CAE WATCHES/WARNINGS/ADVISORIES. GA . None. SC . None.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
