Key message 1: Rain will arrive early Sunday morning and should become widespread by late morning. Minimal hydro impacts from the rain expected due to ongoing drought conditions. Seeing the first waves of light precip spreading eastward aloft early this evening, but the boundary layer remains so dry that none of it appears to be reaching the ground. Eventually, during the late evening and into the overnight hours, the column will moisten and we could start to see some light rain reaching the ground, but most places will remain dry or perhaps just have some sprinkles before daybreak Sunday. Note there is an outside chance that some of the higher elevations could have some light snow or sleet at onset, but a quick changeover to rain should take place, so no snow accum is expected. For tonight, the area of low pressure pushes eastward across the lower MS River basin. The low is expected to move slowly across MS/AL/GA on Sunday, with a weak in-situ cold air damming wedge remaining east of the mtns and the wedge/warm front attempting to push into the lower Piedmont. Current trends bring slightly higher rainfall amounts (0.5-1.5 inch) east of the mountains with isolated higher amounts along the usual areas of the Blue Ridge Escarpment. This rain is expected to be beneficial, what with the widespread ongoing drought and very dry vegetation/soil. Not anticipating much in the way of hydro impacts. A few of the models also have a small amount (< 50 J/kg) of sbCAPE in the southern zones of the CWA Sunday morning and into the afternoon. Confidence is very low on the instability coming to fruition, but cannot rule out a brief rumble of thunder or higher rain rates in those southern zones. Rain timing starts with scattered showers overnight and then a widespread steady rain spreading from SW to NE after daybreak Sunday. The system should have rain tapering off west to east and be out of the area between 9PM Sunday to 1AM Monday morning. Behind the system, dry air returns and cuts off precipitation chances once again. Key message 2: Dry with a warming trend next week, perhaps warming to near record levels by Thursday. As our Sunday rainmaker departs by Monday, the northerly sfc pressure gradient will weaken and in concert with the influx of deep layered dry air, maximum temperatures will be boosted to 8-10 deg F above climo. Upper heights atop the SE CONUS will rise through midweek as a warming llvl WSWly flow develops. Under broad flat ridging aloft, no pcpn is expected as piedmont maximum temperatures rise into the middle 70s...near the mid February records. It remains to be seen whether developing baroclinic zone can make any inroads into the cwfa on Friday, or perhaps develop enough weak instability to aid in any shower development. But the bigger news to round out the workweek, is we are expecting one more day of near record warmth. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... At KCLT and elsewhere: VFR conditions thru the end of operations this evening, with thickening mid-level clouds, and most likely still VFR when operations ramp up in the pre-dawn hours as it will take some time for developing light rain to bring the ceiling/vis down enough to cause a restriction. Will handle the uncertainty at onset with a PROB30. But, when it does, conditions will deteriorate rapidly down through MVFR to IFR in the mid/late morning. Cannot rule out most terminals dropping to LIFR on the ceiling in the afternoon on Sunday and staying there through the rest of the period, but will stay more optimistic for this issuance and for the time being and keep most places IFR until the late afternoon. Wind will start out light SE, but probably will shift to E/NE once the precip really starts and we get that response to the development of a cold air damming wedge in place. Outlook: Rain and associated IFR or lower restrictions remain into Sunday night. Restrictions improve Monday as dry conditions return and persist through the first part of the week. && .GSP WATCHES/WARNINGS/ADVISORIES... GA...None. NC...None. SC...None. && $$ CP/CSH/PM
