(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 krnk 250829 afdrnk area forecast discussion national weather service blacksburg va 429 am edt Sat may 25 2019 Synopsis A weak backdoor frontal system will sag slowly southward today toward the nc va border by tonight, likely triggering scattered showers and thunderstorms this afternoon and evening. The front will linger near the virginia north carolina border through Monday, then drift back to the north as a warm front Tuesday. Another cold front will reach the area by the end of the week. Otherwise, aloft, an area of high pressure will keep the region warm and humid through most of the week ahead. Near term through tonight As of 415 am edt Saturday... a large and strong subtropical ridge remains anchored over georgia while the westerlies remain active from the central plains to the northern mid-atlantic and new england. A series of disturbances aloft continue to track around and along the northern periphery of the upper ridge. These disturbances are close enough to squash the northern extent of the upper ridge southward from time-to-time, allowing scattered convection developing across the midwest great lakes region to slide east- southeast or southeast with time, thus having the potential to skirt at least the northern areas of the cwa. Today will be no exception to this pattern as a notable disturbance tracks across oh into pa overnight. The hires cam models to varying degrees indicate once again the potential for isolated to scattered convection this afternoon, and this pattern is consistent with recent events. The i64 corridor will remain the most favored area for convection again through the weekend and into early next week. There is the potential that one or two storms could be strong to severe as CAPE values are quite high, but shear is low under the ridge. SPC has actually, for now at least, removed the CWA from the risk of severe today and Sunday, just leaving general thunder, confining the severe threat closer to the md WV va border. With regard to pops, not comfortable going any higher than 50% at this point as there is too much uncertainty as to how far convection will penetrate southward into the cwa and how long it will last into the evening. The hrrr remains more agressive with convection than the namnest, which generally has had a better handle on convection evolution and coverage the past few days. Thus, have advertised 50% pops north to 20% pops south, ending after midnight. Temperatures will remain above normal, but a slight period of northeast winds and more cloud cover today along with afternoon showers thunderstorms north, should hold temperatures down a few degrees from Friday's readings. However, feel the mavmos is indicating too much cooling, so leaned heavily toward the ecmwf mos guidance for today's highs. Not much variation in low temperatures with it remaining more like mid-july than late may. So for today look for highs in the mid 80s west to lower 90s east, except mid to upper 70s mountains, with lows tonight mostly in the 60s, near 70 southeast. Confidence in forecast parameters temperatures - moderate to high, precipitation probabilities - low to moderate, winds - moderate, thunderstorm probabilities - low to moderate. Short term Sunday through Tuesday night As of 233 am edt Saturday... the weather pattern remains stuck as a strong broad upper level ridge continues to sit over the gulf states. The chances for rain Sunday and Monday will come from meso-scale convective systems (mcs) tracking from the plains to the midwest, then sliding southeast toward the area once they are in the ohio river valley. The two mcs's that approach the area Sunday night and Monday night will be in the decaying stage, but still could bring some isolated strong to severe weather to the area. Majority of the showers and thunderstorms in the afternoon will be the typical summer-like convection, fading in the evening. Each MCS will have a trailing cold front associated with it, but will not provide much relief from the heat. High temperatures both days will range in the 80s across the mountains to the low to mid 90s east. These temperatures are around 10f-15f warmer than normal. Long term Wednesday through Friday As of 321 pm edt Friday... Wednesday, the ridge starts to get squashed to the southeast as upper trough digs across the upper midwest great lakes. Still appears very warm hot for most but should see an uptick in storms firing in the afternoon evening across the mountains foothills. Still only slight to low chance pops. Highs will be in the 80s in the mountains, to lower to mid 90s east of the blue ridge. At present humidity levels dewpoints should preclude any heat index issues, but could approach 100 in the piedmont Tuesday afternoon for an hour or two. Surface front shifts toward the area Thursday with a better chance of showers and storms, though the main dynamics jet stay north of the area. With heat abating, should see temps cooler. Storms may be strong given how we heat up prior to the frontal passage, so more energy to work with. Still only expecting isolated to scattered |
storms with best coverage in the mountains. Temps drop back to upper 70s to lower 80s in the mountains, to mid 80s to around 90 east for highs Thursday. By Friday, models show zonal flow with front pushing off the coast and high pressure building in from the ohio and tennessee valleys. Temps will be closer to normal for the end of may with 70s in the mountains, to lower to mid 80s east. Aviation 08z Saturday through Wednesday As of 200 am edt Saturday... mostlyVFR conditions expected through the TAF valid period. The forecast area will remain on the northern periphery of a strong mid-level subtropical upper ridge. The main and best dynamics will remain north of the area, with large scale subsidence further south. Temperatures heights aloft are quite high for this area with the 0z rnk sounding showing a 500mb height of 588dm and a temperature of -8c. More typical of july than late may. This pattern will generally continue for the next few days. The thing to keep an eye on are stronger disturbances tracking across the great lakes and into the northeastern u.S. That will attempt to periodically squash the upper ridge southward. One such disturbance is expected this afternoon evening, enough to support isolated to scattered northwest flow showers thunderstorms during the afternoon evening, then dissipating, much as we have seen the past few days. SPC has backed off the severe threat for our area, but has left much of the area in general thunder. Best chances will be across the west and north. Have indicated this in the tafs with vcts west north vs. Prob30 east, and none indicated at kdan at this time. Outside isolated to scattered afternoon evening showers thunderstorms, main concern will be late night early morning radiational fog. Seeing 1 4sm fg vv001 at klwb for the past several hours this morning, and this will likely continue as it often does in the summertime through daybreak or shortly thereafter. Would also expect kbcb to see fog developing very soon. Otherwise, feel it is too warm dry for fog tonight and most sites will seeVFR ceilings and visibilities throughout the taf valid period, with CU bases generally aoa035. The development of fog overnight morning will be largely dependent on where it rains the evening before. Much of the rain the past few days has been in the greenbrier valley. Winds will be variable from NW to NE to SE to SW through the day, finally ending on SW 5-10kts by afternoon. Confidence in forecast parameters ceilings - moderate to high, visibilities - moderate to high, winds - moderate, thunderstorm threat - low to moderate. Extended aviation discussion...VFR conditions are expected across the region into early next week as high pressure offshore maintains a hot humid airmass across the region. Exception is with evening overnight fog but confidence low on development at this time. Scattered showers and thunderstorms resulting in brief sub-VFR conditions are also possible Sunday in the west, and early next week across most of the mountains, but more isolated coverage for Monday into Tuesday. Isolated convection possible in the western mountains on Wednesday. Climate As of 815 pm edt Friday... a new record high temperature of 85 degrees was set at blacksburg virginia today, while the old record of 92 degrees was tied at roanoke. Please see the wbcrerrnk product for added details. High temperatures will be close to records at few climate sites Saturday through Sunday.
