Fxus61 krnk 221152 afdrnk area forecast discussion national weather service blacksburg va 652 am est Fri feb 22 2019 Synopsis A frontal system will remain nearly stationary close to the virginia north carolina border through Saturday. A series of lower pressure systems aloft will track along and near the frontal boundary bring periods of mostly light to moderate rainfall to the region through Saturday. This will continue the threat for flooding across the region through the weekend. A cold front will push through the region Sunday finally bringing an end to the rain by afternoon. Temperatures are expected to be near normal values through the weekend. Near term through tonight As of 415 am est Friday... very little change in the upper atmospheric pattern across the u.S. Is expected through the period. Deep troughing will remain in the western u.S. With a strong 590+dm ridge aloft just off the florida east coast. The ridge is keeping a baroclinic zone nearly stationary frontal boundary draped across the region. Meanwhile, a series of upper-level disturbances will track northeast from the main upper low in the southwest u.S. And along and through the baroclinic zone. To complicate matters, a new area of canadian high pressure will move from the great lakes toward new england allowing yet another wedge of cold air to develop east of the appalachians, having just seen the last one (largely responsible for our most recent snow ice storm) depart Thursday afternoon. With the baroclinic zone established over near the blacksburg forecast area today through Friday and increasing isentropic lift as the cool air wedge develops today through Saturday, along with numerous upper-level impulses steered by the mean southwest flow aloft across our region, look for periods of rain today through Saturday. While most of the rain will be light, brief periods of heavier rainfall can be expected. Expected QPF today and tonight will be mostly in the 1 to 1.5 inch range, with the higher totals in the west where upper-level forcing is better. Soil conditions across much of the rnk CWA remain very saturated thanks to repeated recent rainfall events for months on end along with recent snow ice melt. Rainfall today and tonight will simply aggregate the situation. Thus, the flood watch, which was issued for the entire forecast area yesterday afternoon, will remain in effect until Saturday night west and Sunday morning east. Finally, there are a couple of other considerations complicated by the development of yet another cold air wedge tonight and early Saturday. As the cool wedge intensifies over the area today and tonight, sufficient dry air may be entrained southward into the northern fringe of the advancing rain shield for temperatures to wet-bulb down toward the freezing mark late tonight early Saturday across the southern shenandoah valley into the greenbrier and new river valleys. Thus, a brief period of freezing rain and or freezing drizzle is possible around daybreak Saturday. With temperatures only expected to reach 32f and limited to spotty locations at that, ice accumulations are expected to only amount to a trace at best. Will mention in the hwo ehwo, but no headlines are warranted at this time. The other consideration related to the wedge is that the attendant drier air advecting southwest could reduce precipitation amounts for a while tonight Saturday morning across northern parts of the cwa. With the wedge beginning to erode again later Saturday into Sunday, no changes to the cwa wide flood watch are warranted given as noted above the very saturated soil conditions across the entire region. With the development of a wedge once again, look for cold temperatures to return today and Saturday. Temperatures will hold mostly in the 30s higher elevations to 40s lower elevations through Saturday. Confidence in forecast parameters temperatures - moderate to high, precipitation probabilities - moderate to high, winds - high. Short term Saturday through Monday night As of 300 am est Friday... very active weather into the first part of next week with both a hydro and wind threat. The deep upper trof ejecting out of the southwestern us will amplify the southwesterly flow aloft and moisture transport over the appalachians and central mid atlantic region through Saturday. Simulated water vapor imagery shows a well defined moisture plume with teleconnections back to the pacific ocean, helping to generate precipitable water valued of 2 to 3 standard deviations above normal. Acting on this moisture will be prolonged strong isentropic lift as a warm front pushes the moist air up and over a well entrenched wedge east of the mountains. This will generate additional widespread rainfall on top of our saturated ground, and good clustering of ensemble precip plumes adds confidence in this very wet scenario. Temperature profiles may also be problematic for some freezing rain with surface readings near freezing at the typical locations in the heart of the wedge Saturday morning, but it currently looks like we will stay just warm enough to avoid any icing. With the ground already saturated from recent and ongoing precipitation, expect any ongoing flooding will be amplified and new flooding initiated before the best forcing slides to our north by Saturday evening. Any lull in the action will be short lived as low pressure moving into the great lakes will push showers ahead of a cold front back into the region form the west later Sunday night, with an outside chance of some thunder as well but would like to see instability lapse rates a bit more pronounced to warrant a mention in the forecast.

Low level southwesterly winds will amplify considerably ahead of the front Saturday night with strong wind gusts developing across the mountains of north carolina, up through the grayson highlands and mountain empire or virginia, and into western greenbrier in west virginia. With the waterlogged soil some uprooted trees and associated power outages look possible. The front will cross the area Sunday morning with the low level wind field still energized. Expect some significant wind gusts with the actual frontal passage, followed by strong gusty winds spreading eastward across the entire region even into the piedmont through Sunday afternoon, along with a greater than normal likelihood for uprooted trees and power outages due to the waterlogged soil. Strong gusty winds will continue west of the blue ridge as lowering inversion squeezes the flow in the mountains. Moisture behind the front looks to be fairly limited and this should inhibit development of upslope showers. Winds gradually subside as high pressure builds in with quiet weather for Monday. Long term Tuesday through Thursday As of 345 pm est Thursday... transient cool high pressure will move out to sea Tuesday night. A northern stream cold front will join forces with a southern stream disturbance late Tuesday night Wednesday morning to bring a chance for rain back into the area. At this time, the two do not phase until both systems move off the mid atlantic coast Wednesday evening. Dry high pressure will follow with no rain expected until the weekend. Near normal temperatures are expected for next week. Aviation 12z Friday through Tuesday As of 645 am est Friday... poor aviation conditions expected through the TAF valid period. Most conditions early this morning are MVFR, but are expected to deteriorate quickly to ifr-lifr by mid to late morning and remain mostly ifr-lifr through the remainder of the TAF valid period in light rain and fog, transitioning to light rain, drizzle, and fog overnight into early Saturday. Ceilings will mostly fall into the 005-015 range while visibilities generally hold in the 2-4sm range through 22z, then mostly in the 1 2-2sm range after 22z. This as the result of a stationary front draped across the region which will remain in the area through Saturday while high pressure to our northeast helps to develop another wedge through the day today into Saturday, and a series of upper-level disturbances move northeast from deep low pressure in the south central u.S. Winds will generally trend toward the east and northeast as weak low pressure remains to our southeast and high pressure strengthens to our northeast. Speeds are expected to be mostly 5-6kts or less through the TAF valid period. As southeast flow develops toward the kblf area, speeds may increase in that region more toward 10kts with low end gusts. Confidence in forecast parameters ceilings - moderate to high, visibilities - moderate to high, winds - moderate to high. Extended aviation discussion... cold front is expected to sweep east through the terminal forecast area on Sunday, gradually diminishing ending the threat for precipitation with subsequent return toVFR conditions east of the blue ridge by during the afternoon. However, colder upsloping winds from the west or northwest following the frontal passage will likely maintain the threat for sub-vfr weather west of the blue ridge through Sunday night, but dry air will allowVFR conditions to return to all areas Monday, which should continue into Tuesday before the next frontal system arrives in the wed-thu time frame. Winds are expected to become quite strong and gusty behind the front Sunday into Monday, especially over the mountains, until high pressure can sufficiently build into the region later Monday into Tuesday, thereby allowing winds to gradually relax. Hydrology As of 430 am est Friday... a quasi-stationary frontal boundary will remain over or near the rnk CWA during the next several days as a series of weather disturbances lift northeast along the boundary. Each system will bring a period of widespread mostly light to moderate rain, possibly briefly heavy at times, especially in the south and west. Rainfall totals over the next several days are expected to be in the 1 to 3 inch range in many areas, with locally higher amounts quite possible. Runoff from rain falling on a totally saturated ground from a very wet fall and winter season, combined with recent snow ice melt, will increase the threat of general areal flooding in low-lying, poor drainage, and normally flood prone areas as well as along creeks, streams, and even some of the main rivers with time. Ensemble river forecasts reflect minor to potentially moderate flooding of most major waterways and associated tributaries. Please remain abreast of possible flood and river flood warnings that me be issued through the weekend. Rnk watches warnings advisories Va...
