580 FXUS61 KRNK 272321 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 721 PM EDT Thu Mar 27 2025 .SYNOPSIS... High pressure moves offshore Friday, with southerly flow providing above normal temperatures heading into the weekend. The next significant chance of showers and thunderstorms arrives for Sunday and Monday. && .NEAR TERM /THROUGH FRIDAY/... As of 115 PM EDT Thursday... Key messages: 1) Temperatures trending warmer. 2) A few showers possible north of U.S. 460 Friday. An area of high level clouds will skirt across the area tonight. Models have backed off on showers until Friday morning. Still some isentropic lift arrives Friday in advance of a warm front which may bring a few very light showers to areas north of U.S. 460 Friday with best chances north of I-64 in WV. Expect more clouds in the morning then clearing south to north through the afternoon. Light southwest winds tonight will pick up some Friday afternoon with gusts to 20 mph. After lows in the 40s tonight for most, some 30s deeper valleys, temperatures should jump into upper 60s to mid 70s Friday. If cloud cover lingers longer, temps could be cooler mainly over the Alleghanys east toward Lynchburg. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/... As of 100 PM EDT Thursday... Key Messages: 1. Dry Saturday, showers arrive Sunday ahead of a cold front. 2. Above normal temperatures through the weekend, warmest on Sunday. A surface high will be centered in the Atlantic off the Carolina Coast by Saturday morning, with southwesterly flow around the high advecting warmer air and more moisture into the area, and 500mb ridging extending into the region. That all being said, confidence is high for above normal temperatures and dry weather Saturday. Some models are showing light showers developing as early as Sunday morning ahead of the next approaching cold front though looks more likely Sunday afternoon, as moisture continues to increase over the area. Dewpoints will trend upward, into the mid to upper 50s in the west, and upper 50s to low 60s in the Piedmont by late Sunday. With the additional plentiful moisture in the region, cloud cover will increase Friday night through Saturday. Despite the cloud cover, temperatures Saturday will be 15 to 20 degrees above normal, in the low to mid 70s west of the Blue Ridge, and upper 70s to around 80 in the Piedmont. Sunday will be slightly cooler with clouds and precipitation, though still 5 to 10 degrees above normal. && .LONG TERM /MONDAY THROUGH THURSDAY/... As of 100 PM EDT Thursday... Key Messages: 1. Passage of cold front Monday will bring showers and possible thunderstorms. 2. Another round of showers possible late in the week. The long term forecast period will be fairly active, with a couple systems crossing through the local forecast area. A strong low pressure system will move into the Ohio Valley from the central US, and bring a cold front through the area on Monday. With dewpoints in the 50s to 60s, and the timing of the frontal passage itself during peak heating, Monday afternoon/evening, there is potential for scattered thunderstorms. However, models do still exhibit differences in timing and strength of the front as it moves through the region, which will impact the coverage and intensity of any storms that develop. Behind the front, colder air will fill into the area, and temperatures Tuesday will be cooler. Cold air advection will also lead to gusty winds late Monday night and Tuesday. Temperatures will trend warmer once again for Wednesday and Thursday. Another low pressure system will start to organize over the central US late in the week, as an upper trough deepens west of the Mississippi. Significant differences in the timing and evolution exists with this system in the global models. Therefore, forecast uncertainty is high for later in the week, but overall, it does look like another frontal passage will come through the forecast area later in the week. && .AVIATION /23Z THURSDAY THROUGH TUESDAY/... As of 720 PM EDT Thursday... VFR conditions look to remain for the entire TAF period for all terminals. Winds will remain out of the west/southwest through the period, and are not expected to be much stronger than 5-10 knots. Will see some mid and high level cloud cover tonight into Friday morning, then becoming partly cloud in the afternoon. Any light rain showers will stay mainly west/northwest of BLF/LWB through 00z Saturday. Confidence in the above forecast is high. .EXTENDED AVIATION OUTLOOK... VFR expected Friday night into late Saturday. By Sunday morning, rain showers move back into the area, with sub- VFR flight conditions possible. A line of showers/few storms is expected Monday. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None. WV...None. && $$ SYNOPSIS...EB/WP NEAR TERM...RCS/WP SHORT TERM...AS LONG TERM...AS AVIATION...RCS FIRE WEATHER...EB/WP
