Special Weather Statement issued for Greenbrier and Bath Counties due to some light freezing rain possibly mixing in with the rain this morning. Precipitation will change to just rain in the next few hours. Otherwise, no other significant changes to the forecast. && .KEY MESSAGES... 1) Widespread rain today with Marginal Risk for excessive rainfall. 2) Much warmer temperatures this week, with mostly quiet weather until rain chances return late week as multiple systems move through. && .DISCUSSION... KEY MESSAGE 1: Widespread rain today with Marginal Risk for excessive rainfall. A vigorous area of low pressure over the lower Mississippi Valley will move east today crossing the southern Appalachians and Southeast States. Southerly winds will tap rich supply of Gulf moisture with large swath of moderate to locally heavy rain for much of the southeast CONUS in addition to a line of thunderstorms that will rake the Deep South. For our forecast area we are anticipating a day of much needed rain. Some of the colder elevations across our northern CWA may experience a rain snow mix this morning, but warming aloft and lack of subfreezing air at the surface should ensure this to be an almost entirely rain event. The period of rain should last about 12-15 hours...onset this morning and ending by midnight tonight. Temperatures today will rise very little. May see readings sneak into the 40s, but clouds and persistent precip will mute the diurnal recovery. Once the air is saturated, dewpoints will also come up, so look for patchy fog and mist to go along with the rain. For areas that still have some snow cover (Highlands and into the Greenbrier Valley) watch for patchy dense fog per relatively warm air passing over the cold ground. Will also have low visibility issues in the higher elevations where the cloud base intersects the ridge tops...the HRRR forecasting sub-half mile visibility for the Blue Ridge Parkway, along with the other various mountain tops/ridges this afternoon and evening. This storm is expected to deposit about an inch of rain for most folks with localized amounts of up to 1.25 within the areas of strongest isentropic lift. Models suggest a narrow corridor of stronger lift to pass along the VA/NC border...so this may be the geographic area to watch for these higher amounts. Flood risk is low. The Weather Prediction Center maintains a Marginal Risk for excessive rainfall over most of the forecast area. While localized urban and poor drainage flooding is possible, this widespread soaking is generally beneficial due to ongoing drought conditions. In order to exceed the rain expectation we would need some instability which is lacking this far north latitude. CAPE forecast for our CWA is anemic... mixed layer under 50 j/kg. Thunderstorm probs get up to about 5% in the piedmont late this afternoon, so this would be the only area that probabilistically could exceed rainfall expectation if deep convection where to occur. All things considered, no headlines for flooding planned. KEY MESSAGE 2: Much warmer temperatures this week, with mostly quiet weather until rain chances return late week as multiple systems move through. High pressure builds in across the Southeastern US for the early part of this week, keeping dry conditions in place through midweek. Upper-level ridging will also be in place, with a mostly zonal flow aloft. The high shifts east into the Atlantic late Tuesday, with a warm southwesterly flow returning to the region. This will cause temperatures to be well above normal for the first time in weeks, around 15-20 degrees above normal. Highs will be in the 50s on Monday, but rise into the 60s area-wide each day for the rest of the week through Friday. Some locations in the southern Piedmont will likely rise into the low 70s late week. Overnight lows mainly remain in the 40s. By Saturday, a cold front will have moved through, with a big cooldown expected late next weekend. Rain chances return late Wednesday into Thursday, as upper-level energy will remain off to our north, but enough moisture along with a weak boundary across the northern Mid-Atlantic may allow for some light showers in the WV mountains. Confidence is low in coverage of rainfall initially, but light showers are expected to spread across the mountains and areas east of the Blue Ridge on Thursday with PoPs around 30%. On Friday, the next system and main cold front move into the area. Models are inconsistent with rain coverage once again for the late week system, but PoPs are around 40-50% for the entire area as the front moves through. Temperatures will be warm enough that all precipitation will fall as rain. && .AVIATION /13Z SUNDAY THROUGH THURSDAY/... MVFR conditions this morning, transitioning to IFR/LIFR this afternoon and evening. High confidence for deteriorating weather conditions this morning with lowering cloud bases leading to cigs between 1K-3K after 15Z/10AM then blo 1kft after 21Z/4PM. Visibility will also lower with time, light to moderate rain occurring across the entire area through about 03Z/10PM this evening. Ridge obscurations are likely this afternoon and evening...surface winds under 10 kts. EXTENDED AVIATION OUTLOOK... Precipitation moves east of the area after 03Z/10PM Sunday night. VFR conditions develop Monday and last through Wednesday. The exception will be some upslope rain showers and borderline MVFR ceilings in the mountains Wednesday. Winds will shift to the north behind the departing storm over the southeast CONUS tonight, then transition back to a southwesterly direction by Tuesday. By Wednesday, increasing SW winds may become gusty to 25 knots as front approaches from the northwest. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ DISCUSSION...CG/JCB/PM AVIATION...PM
