Area Discussion for - Baltimore, MD/Washington

      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus61 klwx 250759 afdlwx area forecast discussion national weather service baltimore md washington dc 359 am 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 today. A shower or two can't be ruled out over southern maryland or along the chesapeake bay coastline and adjacent areas later this afternoon and early evening. Temperatures will reach the middle to maybe upper 70s today before dropping into the middle to upper 50s tonight. Short term Monday through Tuesday night High pressure will move out to the northeast Monday and Monday night. A persistent wind from the east or northeast will usher in additional low-level moisture during this period. Dewpoint temperatures, or the indication of the amount of moisture in the air, will gradually rise out of the 50s into the 60s during the day. With this increased moisture and departing high pressure, additional showers are expected to develop not just in the eastern zones but parts of the virginia piedmont, along the blue ridge, and in the potomac highlands Monday afternoon and evening. Temperatures will reach the middle 70s then fall only into the middle 60s Monday night. About the time that showers Monday evening begin to wind down or dissipate, we could have a tropical system lingering off the east coast near the virginia and north carolina shoreline. This system is expected to push onward toward the northeast over the open atlantic Tuesday and Tuesday and not have any path toward the delmarva beaches since there will be an upper level trough approaching from the ohio valley. Although we don't anticipate a direct impact with this system Tuesday into Tuesday night, it could have an effect on our coastal waters of the chesapeake bay and tidal potomac in terms of coastal flooding. Also, showers and perhaps a diurnal thunderstorm or two could evolve in parts of our region. The east to southeast component to the wind expected Tuesday could mean that any modest convection could evolve due to upslope along the blue ridge and potomac highlands. Temperatures Tuesday should approach 80 degrees in most places. Long term Wednesday through Saturday A trough axis crossing the great lakes Wednesday will push a cold front across the mid atlantic. The atmosphere will be sufficiently moist prior to the frontal passage, with respectable instability and modest shear--certainly enough to justify a shower thunderstorm forecast at high chance to maybe likely levels. That said, it is unlikely that it will be an all day rainfall; rather the precipitation FROPA seems to be focused on the timeframe of peak diurnal heating, although the lingering upper trough jet suggests it may not move through quickly. Will be keeping chance pops east of the blue ridge into Wednesday night.

For the rest of the week, continental high pressure building toward the east coast will be the primary weather feature. Consequently temperatures will remain rather mild for late august (highs in the lower-mid 80s, lows mid 50s-mid 60s). Aviation 08z Sunday through Thursday Vfr conditions expected with high pressure to the north then to the northeast by Tuesday. Any showers should be isolated Monday and Tuesday with low confidence as to which terminals may or may not encounter one of these showers. Winds northeast around 10 knots through Monday night. Winds becoming southeasterly around 10 knots Tuesday into Tuesday night. Flight restrictions may linger into Wednesday due to low clouds and perhaps vsby as a result of east flow. Ceilings will gradually lift through the day, but an approaching cold front will support a chance of showers thunderstorms by afternoon evening. While exact convective impact uncertain, odds suggest it wouldn't be widespread or of long duration. But, the lingering moisture could result in restrictions Wednesday night. Thursday should fare better as high pressure builds.VFR likely. Marine A small craft advisory remains in effect through this afternoon for much of the chesapeake bay and tidal potomac. An extention to this small craft advisory has been issued for tonight into early Monday morning. 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 through the day Monday into Monday night. The pressure gradient likely won't be strong enough to support small craft conditions Wednesday or Thursday. But, a frontal passage late Wednesday will support showers thunderstorms so local marine warnings possible. Lwx watches warnings advisories Dc... None. Md... None. Va... None. Wv... None. Marine... Small craft advisory from 6 pm this evening to 6 am edt Monday for anz530-531-536-538-539. Small craft advisory until 6 am edt Monday for anz532-533- 540>542.

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.
