The switch to PHP 7.2 caused many pages that previously worked to quit working. I fixed many but I still depend on users to report ones I missed.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kcae 171037 afdcae area forecast discussion national weather service columbia sc 637 am edt Sat aug 17 2019 Synopsis The pattern of scattered thunderstorms in the afternoon and evening will continue through Sunday. High pressure in the atlantic will direct a moist flow into the forecast area through much of next week. Weak troughing will linger locally. The pattern supports a chance of mainly afternoon and evening thunderstorms. Temperatures will be a little above normal. Near term through tonight Stratus has developed near the coast and pushed into the midlands and csra. Expect mostly cloudy skies and reduced visibilities across much of the central and eastern forecast area this morning, scattering out by late morning. The synoptic setup for today will be similar to the previous day with a sharp moisture gradient over the area and weak upper- level troughing. This will support scattered convection during the afternoon lingering into the evening. Convection allowing models (cams) suggest higher convective coverage in the coastal plain and the higher terrain of the upstate. Though outflow boundary interactions should shift the focus in late afternoon evening to development into the midlands and csra. Weak forcing and weak to moderate instability will limit the potential for severe weather. There may be a few isolated storms which are able to produce strong downburst winds given the mid- level dry air high dcape values across much of the fa. Expect highs generally in the low to mid 90s with overnight lows in the low to mid 70s. Short term Sunday through Monday night Surface high pressure in the atlantic will direct a weak southerly flow into the forecast area. The models indicate a weakness in h5 ridging over the region. The pattern supports continued hot conditions with a chance of mainly afternoon and evening thunderstorms. Followed the guidance consensus with highs mainly in the middle 90s. Expect peak heat index value 100 to 105 and below advisory criteria. The guidance consensus supports pops 20 to 40 percent with the greater values in the southeast section closer to deeper moisture. |
Long term Tuesday through Friday The GFS and ECMWF indicate little change in the overall pattern during the medium-range period. We should continue to be on the western side of the bermuda high. A weakness at mid levels between the atlantic and the southern plains ridge is forecast to continue. The pattern supports slightly above normal temperatures with scattered mainly afternoon and evening thunderstorms. Any severe thunderstorm threat will be strictly pulse-induced as the atmosphere will be devoid of any substantial shear. Aviation 12z Saturday through Wednesday This morning, stratus has developed near the coast and is impacting or expected to impact all TAF sites. Ifr lifr ceiling restrictions will continue through the early morning. The stratus will scatter out through mid to late morning. The weak surface boundary will remain over the area today. Winds will be light and variable through the remainder of the period. Scattered thunderstorms will develop in the afternoon, with higher coverage to the east coinciding with the deeper moisture. Though outflow boundary interactions may shift the focus of development into the midlands and csra in the late afternoon or evening. Confidence in vcts is highest at ogb, which is nearer the deeper moisture, but given the scattered nature of the storms confidence is low at the other TAF sites. Overnight, we expect another round of stratus to develop near the coast and push inland bringing ifr lifr ceiling restrictions. Patchy fog may also develop with drier air aloft and abundant low-level moisture. The cira simulated satellite data, which has performed well the past few nights, indicates the potential for restrictions at all TAF sites near sunrise. Extended aviation outlook... Seasonal conditions are expected with periods of restrictions in the early morning from low stratus or fog. Then additional restrictions possible in the afternoon and evening from widely scattered convection. Though vfr should be the dominating rules at the terminals. Cae watches warnings advisories Ga... None. Sc... None. |

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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. |
