Fxus61 klwx 251855 afdlwx area forecast discussion national weather service baltimore md washington dc 255 pm edt Sun aug 25 2019 Synopsis Strong high pressure will build north of the region today. Low pressure likely will develop off the carolina coast early in the week and move out to sea by Tuesday. A cold front will cross the region on Wednesday. Near term through tonight High pressure ridging southward to the east of the appalachian mountains will promote dry conditions and northeasterly flow through the remainder of the day today. Similar to yesterday a fairly widespread cumulus field developed and this will persist through the afternoon and into the evening. A shower or two is possible as well over southern maryland or the chesapeake bay. Temperatures will top out in the 70s to locally near 80f. Some decrease in cloud cover is expected initially tonight but low level northeasterly will promote low level moisture increase which will lead to a return of clouds overnight and towards morning, especially across portions of eastern WV and central va. Lows will fall into the 50s 60s. Short term Monday through Tuesday night Surface high pressure will be positioned near coastal maine by Monday with an area of low pressure southeast of the carolinas. This will help to turn low level flow even more easterly, which will promote an increasingly marine influence. That in combination with an upper trough moving towards the area from the mississippi valley will act to bring more cloud cover in addition to the possibility of some isolated to scattered showers, with the highest probabilities in southern md and central va. Highs Monday will likely remain in the 70s. Monday night will see the passage of an upper level shortwave, which will act to bring scattered rain showers to portions of the region overnight and into Tuesday morning, especially along and west of the blue ridge. Lows Monday night in the 60s. By Tuesday, the shortwave will pull eastward, and the high pressure over the northeastern us will break down. Additionally, the low offshore will slowly move northeastward. This will lessen the gradient over the region, and flow will turn more southeasterly in nature. This will allow dew points and temperatures to slowly rise, with highs Tuesday likely back up near 80f. Some scattered showers are possible as well. Lows Tuesday night will hold in the 60s to near 70f. Long term Wednesday through Sunday The upper level ridge that has been in place over our region will start to break down early on Wednesday. A strong upper level trough will shift eastward into the great lakes region and into the mid- atlantic and new england. A surface low associated with the upper level trough will move through canada and its associated front will approach and move through our region from the west Wednesday afternoon and into early Thursday. A surface low or possibly a weak tropical system will move through the western atlantic ocean. This will lead to increasing moisture in our region but should limit day time heating to mid 80s. The limited heating will lessen the impact of severe weather but thunderstorms and showers will be possible as the frontal boundary moves through our region.

The cold front is expected to be fully through our area by Thursday morning leading to a return of drier air. High pressure will build back into our region Thursday through the early parts of this upcoming weekend. Another cold front will approach our region late Saturday and into Sunday bringing the next chance for precipitation. Daytime temperatures will trend upwards during this period from the upper 70s on Thursday to the mid to upper 80s by Saturday. Aviation 18z Sunday through Friday Vfr conditions are expected through the remainder of today with high pressure to the north. An increasingly easterly flow will lead to lower and thicker cloud cover late tonight into Monday and a period of MVFR conditions are likely at cho, and possible elsewhere. These conditions may persist or redevelop Monday night into Tuesday morning. A few rain showers become possible Monday and Tuesday as well. An easterly to southeasterly flow will combine with a approaching cold front to increase cloud cover over our region Wednesday. Ceilings could be low enough that subvfr conditions will be possible. Brief restrictions of MVFR to ifr could be possible as showers and thunderstorms move through terminals. The cold front will move through our region by Thursday morning leading to clearing skies and mainlyVFR conditions expected at this time. Marine A small craft advisory remains in effect for much of the chesapeake bay and tidal potomac through Monday. Depending on the gradient between the high to the north and the developing tropical system along the east coast, additional small craft advisories may be needed Monday night into Tuesday. As a cold front moves through the waters, small craft advisories maybe needed on Wednesday and into early Thursday. Tides coastal flooding Water level anomalies on the western shore of the chesapeake bay and along the tidal potomac have continued to trend upward with persistent northeasterly flow. Minor tidal flooding becomes possible tonight through Wednesday, especially as flow turns more easterly and then southeasterly Tuesday into Wednesday. Lwx watches warnings advisories Dc... None. Md... None. Va... None. Wv... None. Marine... Small craft advisory until 6 pm edt Monday for anz531>534- 537>543. Small craft advisory until 6 am edt Monday for anz530-536. Synopsis...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
