Fxus61 klwx 211423 afdlwx area forecast discussion national weather service baltimore md washington dc 1023 am edt Wed aug 21 2019 Synopsis An upper level disturbance will cross the region this afternoon and evening. A cold front will approach the ohio valley Wednesday, sinking into our area Wednesday night into Thursday, possibly stalling into Friday. Behind the front, high pressure will build over the region for the weekend. Near term through tonight An upper level trough is crossing the appalachians this morning and will move through the region during the mid to late afternoon hours, followed by a second weaker shortwave this evening. At the surface, a weak pressure trough is present in the lee of the mountains this morning and this will gradually push eastward through the day and be east of the region by tonight. More cloud cover is present this morning but breaks of sunshine are expected and this will allow temperatures to rise into the upper 80s to low 90s. Instability will not be as impressive as what we saw on Tuesday, given the additional cloud cover and slightly cooler temperatures, and the synoptic lift will be coming through piecemeal and focused further north. That being said, 1000-2000 j kg of SBCAPE should develop by this afternoon, along with modest low level lapse rates and 0-6km shear around 20-25 knots. These ingredients will support at least an isolated threat for severe thunderstorms today, with damaging winds and large hail continuing to be the primary threats. Initial development is likely to occur in the surface trough near or just east of the appalachians in the mid afternoon as the primary upper trough moves through. These showers thunderstorms should then progress eastward across the metros during the remainder of the afternoon hours and into the evening. A second round of activity is possible, but is less certain during the mid to late evening as the second weaker shortwave moves across. Shower and thunderstorm activity will then dwindle heading into the overnight, with partly cloudy skies and mainly dry conditions persisting overnight. Patchy fog will be possible towards morning as temperatures bottom out in the middle 60s to middle 70s. Short term Thursday through Friday night The cold front will slowly drift into our area Thursday morning, helping spark scattered showers and thunderstorms during the afternoon and evening hours once again. Given the front will be gracing us with its presence, while coinciding with shortwave energy tracking overhead, do expect better coverage of showers storms compared to today. Again, instability may be limited given cloud cover and lower temperatures, however we will remain moist and the flow will be parallel to the front. So in addition to isolated strong to severe storms, heavy rain resulting in isolated incidents of flooding will be a concern. The front shifts southward Thursday night into Friday, but likely lingers close enough nearby to bring additional scattered showers and storms on Friday afternoon and evening, favoring our southern zones. Temperatures noticeably cooler on Friday, likely holding in the 80s area wide. A drying trend should commence Friday night as the front sinks further south into southern virginia.

Long term Saturday through Tuesday High pressure will build into the region from the north Saturday and Sunday. Temperatures will be about 5 to 7 degrees below average. Dry conditions and lower humidity is expected through the period. The high will move to the northeast Monday and Tuesday. This will allow for a return southeast to southerly flow to bring the humidity levels up and a chance of showers or a thunderstorms. The discrepancy remains between the european models and GFS models as to how many and how far north will showers and thunderstorms develop. The european model keeps most, if not all, of our CWA dry through Tuesday. The GFS model brings an upper level disturbance across our region late Monday into Tuesday; thus, the chance for showers and thunderstorms could be higher and farther north. Temperatures will remain a few degrees below average, but humidity levels will rise some. Aviation 14z Wednesday through Sunday Afternoon evening showers and storms can be expected through Friday as a cold front slowly transits the area, bringing periods of subVFR conditions. Patchy fog could also yield MVFR ifr vis, mostly likely at mrb cho. Vfr conditions for all terminals Saturday and Sunday. We can't rule out a shower or thunderstorm near cho late Sunday into Sunday night, which could briefly reduce conditions to MVFR. Winds northeast around 5 knots Saturday and Saturday night. Winds becoming easterly 5 to 10 knots Sunday. Marine Sca conditions expected over the waters today as the gradient increases and a cold front nears the ohio valley. The gradient is expected to relax overnight and remain below SCA criteria Thursday and Friday. The front will drift over the waters on Thursday, lingering nearby into Friday. As such, afternoon and evening showers storms can be expected, some of which will deliver strong gusty winds. No marine hazards expected Saturday and Sunday. Winds northeast around 5 knots Saturday and Saturday night. Winds becoming easterly around 10 knots Sunday into Sunday evening. Lwx watches warnings advisories Dc... None. Md... None. Va... None.

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.
