000 FXUS61 KRLX 230706 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 306 AM EDT Sat Sep 23 2017 .SYNOPSIS... High pressure dominates through early next week. Cold front approaches middle to end of next week. Cooler airmass to follow. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 240 AM Saturday... With a stagnant pattern of ridging surface and aloft, expect little change to the forecast today from yesterday. Any changes will be minor. These changes will be, after dense morning river valley fog, less cirrus from the remnants of the once tropical system off the southern New England coast, and so more sunshine. This will lead to another dry day but with high temperatures a couple of degrees higher than yesterday. Look for highs today near 90 degrees. Tonight will be similar to last night with clear skies and calm winds which will lead to river valley fog.

&& .SHORT TERM /SUNDAY THROUGH TUESDAY NIGHT/... As of 225 AM Saturday... Very few changes to the forecast for the short term as upper level ridging remains in control over the Ohio Valley through early next week. Temperatures remain well above normal and dry conditions will persist. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... As of 225 AM Saturday... Operational long range models remain consistent in a significant pattern change upcoming for the end of the week. Strong cold front to pass late Wednesday/Wednesday night, providing the next chances for showers, and a cooler airmass to follow with 850mb temperatures 10-15C cooler. && .AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
