Fxus61 klwx 171400 afdlwx area forecast discussion national weather service baltimore md washington dc 1000 am edt Thu oct 17 2019 Synopsis Low pressure departing to our northeast will rapidly intensify today before high pressure returns for Friday and into Saturday. Low pressure may impact the area Saturday night into Sunday before a cold front approaches early next week. Near term through tonight A wind advisory continues for the higher elevations through 6 pm this evening. Strong westerly winds will lead to continued upslope shower activity today, with some snow expected above 3000 feet. When all is said and done, could see an inch or two on the highest peaks out west. Additionally, a deepening surface low, located near long island, will continue to strengthen today and move off to the northeast. Gradient winds across northern and central va and all of md are expected to gust around 40 knots as a result, a wind advisory is in effect for those areas through early this evening. A chilly day today, with highs only in the upper 50s to near 60, paired with the strong winds. As the aforementioned low moves away from the area to the northeast, winds will gradually diminish across the region tonight into Friday. Slightly cooler tonight as well, with lows in the low 40s east of the blue ridge, and mid 30s to low 40s west of the blue ridge. Higher ridge tops will see lows in the upper 20s to low 30s. Upslope activity continues tonight as well, but should begin to die down. Short term Friday through Saturday By Friday, all shower activity should be finished out west, and winds will be substantially less. Winds will still be gusting in the 20-25 mph range on Friday across northern areas, but this will quickly diminish into the evening as high pressure builds directly overhead. Highs on Friday will be slightly cooler than average, with temps in the low to mid 60s. Friday night will likely be the coldest night of the forecast period across the entire area. Frost freeze headlines will be needed Friday night west of the blue ridge, with widespread lows in the low to mid 30s. Warmer temps along east of i-95, with lows closer to the low 40s. Between i-95 and the blue ridge, things are a bit less certain, as temperatures will be close to frost advisory criteria, but will wait on issuing that for now. High pressure will shift offshore Saturday, leading to warmer temperatures into the mid 60s. No rain is expected throughout the day on Saturday. Long term Saturday night through Wednesday Low pressure in the southern stream of the jet will track through the southeastern CONUS Saturday night and then most likely off the mid-atlantic coast Sunday. There may be enough warm and moist air that overruns cooler air over our area, bringing the chance for rain. Confidence is still low given that there is still some divergence among guidance as to the timing and how far north the moisture will make it, but as of now it appears that the best chance for rain will be later Saturday night through midday Sunday. A storm system will track east of the rockies Sunday night into Monday and it will intensify as it does so. This will cause a longwave upper-level trough over the central CONUS with upper-level ridging over our area. Surface high pressure may wedge into the mid- atlantic briefly which can bring dry conditions for Sunday night and Monday. However, as the trough shifts east, so to will a stronger cold front. Ahead of the cold front, a southerly flow will allow for warmer conditions along with deep moisture advection. Unseasonably warm conditions are likely Tuesday along with increasing chances for rain. High pressure will return for the middle portion of next week with drier and more seasonable

conditions. Aviation 14z Thursday through Monday Vfr conditions will prevail over the next several days, as high pressure builds into the region Friday into Saturday. However, gusty wnw winds will be the main threat today, especially at the northern terminals, where gusts of 35-40 knots are expected. Winds at cho will be slightly lighter, as the deepening surface low will be farther away than at the other terminals, but could still see gusts up to 30 knots. Winds will decrease Thursday night and Friday, but still gust in the 15-20 knot range throughout the day on Friday. As high pressure settles overhead Friday night into Saturday, winds will be light across the entire area, with no clouds or precipitation to speak of. Low pressure may bring some rain and subvfr conditions Saturday night into Sunday. High pressure may briefly return for Sunday night and Monday, but low clouds and or fog may be stuck underneath the subsidence inversion. Marine Gale warning will continue through early this evening, as a strong low pressure system intensifies to the northeast. Northern portions of the bay will see stronger gusts (near 40 knots), as the low will be closer to that region, with a tighter pressure gradient. Winds will relax somewhat later in the evening, but there is still the chance that the northern bay could see gale conditions later into the evening, but confidence is not high enough at this time, so going with a small craft advisory for all waters. Winds will continue to be gusty through Friday, remaining above SCA criteria through Friday evening. High pressure builds overhead later Friday evening, quickly bringing winds below SCA criteria finally. High pressure will keep winds light on Saturday as well. Low pressure will likely pass by to the south and east later Saturday night into Sunday. An SCA may be needed for portions of the waters during this time. High pressure may briefly return for Monday before a cold front impacts the waters Tuesday. Tides coastal flooding A strong offshore flow will cause anomalies to continue to fall sharply today. Tidal blowout conditions are possible later today into Friday near times of low tide. The offshore flow will weaken Friday night and turn onshore for the weekend. Anomalies will likely increase sharply during this time, and tidal flooding is possible this weekend. Lwx watches warnings advisories Dc... Wind advisory until 6 pm edt this evening for dcz001. Md...

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
