Area Forecast Discussion National Weather Service Columbia SC 739 AM EDT Sat Oct 31 2020

SYNOPSIS. High pressure to the north will provide cooler and drier weather for today. As the area of high pressure moves farther eastward late today and tonight, moisture will begin to gradually return to the region. A reinforcing cold front on Sunday could bring isolated showers with it, but then even cooler weather for early next week.

NEAR TERM /THROUGH TONIGHT/. High pressure centered over the Mid-Atlantic Region this morning will gradually shift eastward and off the New England coast by late this afternoon. Satellite imagery continues to show clear skies across the area this morning and this trend should continue through the first half of today. Winds should stay up a bit through this morning to around midday then tapper off slightly for the afternoon. With a good deal of sunshine today but a cool wind from the northeast expect below normal temperatures. Highs will be range from the middle 60s to upper 60s.

Tonight, low level moisture will continue to increase across the area as the winds become more east near the surface and southeast in the lower levels. Expect clouds to increase overnight and have continued with a slight chance of a shower by morning. This is do to increased moist return flow around the area of high pressure and ahead of the approaching cold front for Sunday. With cloudiness increasing expect lows to be not quite as cool as this morning. Lows will range from 50 to 55 degrees.

SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/. Light scattered showers should be moving across the area after sunrise Sunday ahead of an approaching cold front. Best chance for rainfall ahead of this front should be through early afternoon, then rapid drying from west to east should occur as the front moves off towards the east. In general, qpf amounts will remain light, less than a tenth of an inch for most areas. Highs on Sunday will reach into the upper 60s to the lower 70s ahead of the cold front. Winds turn northwesterly behind the front Sunday night, with cold advection taking hold. Winds should keep lower levels mixed, limiting the radiational cooling potential. Overnight lows fall into the lower 40s across the south, and the middle/upper 30s north. The winds Sunday night will also be enough to keep frost from forming.

By Monday, dry and colder conditions take better hold. Even under sunny skies, temperatures will struggle to reach the mid to upper 50s for the majority of the forecast area. Exception may be the southwestern CSRA, where highs could reach the lower 60s. Monday night the area should be the coldest temperatures of the season so far. Excellent radiational cooling conditions will exist, with clear skies, nearly calm winds, and dry air. This will cause temperatures over the entire forecast area to drop into the 30s. At this time it appears as if temperatures will remain above freezing everywhere. However, with the calm winds, at least some patchy frost is expected to develop after midnight, lasting into early Tuesday morning.

LONG TERM /TUESDAY THROUGH FRIDAY/. After the patchy frost early Tuesday morning, winds will begin turning more out of the south during the day, beginning a warming trend through the end of the week. Highs mainly in the mid to upper 60s on Tuesday and Wednesday, then continued warming into to the lower 70s Thursday and Friday. Overnight lows will also moderate back into the 40s and 50s.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. VFR conditions expected through the period.

High pressure ridging into the area centered over the Mid- Atlantic region and New England. Weak trough along the Ga and SC coast. Onshore flow is developing this morning and strato-cumulus is spreading northwest into the CSRA but expect VFR ceilings. With lingering pressure gradient in place winds will be from the NE today between 5 and 10 knots. Could see a few slightly higher gusts through the morning hours through midday. Onshore flow will increase tonight as the ridge moves offshore and a few showers may develop toward daybreak.

EXTENDED AVIATION OUTLOOK . Another cold front Sunday may lead to restrictions with passing showers.

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

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.
